Hi all. I built a flask app that gives me dog images via an API it requests pictures from.

Im wondering how to make a panel and a button for a page. I imagine being able to give users the ability to click the button and getting a new image in the panel until they decide to quit.

What’s the best way to go about this?

[wind abyss]

How can you process an image and then upload it to a Django ImageField within the model?

[inland oak]

https://www.geeksforgeeks.org/python-uploading-images-in-django/

[wind abyss]

This doesn't explain the processing part though?

At least for me, there is an attribute error whenever I try to process an image file

[inland oak]

Django Image Field stores just path to image
the image is stored at your local path in filesystem

so the procedure would be...

Store image in Image Field

get its path

run processing commands on it

Optionally, saving to DB only at this point the path

The biggest trouble I see with images in general...

that only their path is stored in db

while it should be ideally stored the image itself 😉

[wind abyss]

I see

Do you mind if you could take a look at my code?

[inland oak]

fixing it, you need to do something like....

converting image to base64

and storing base64 in db

usually MongoDB is recommended for file/image storaging though

not sure how well SQL database will work with it

it depends on, can it store images with floating size? should be good without contraint in theory, it needs to be checked

[wind abyss]

class TiffModel(models.Model):
    name = models.CharField(max_length=450)
    image = models.ImageField(blank = True, null = True)
    processed_image = models.ImageField(blank = True, null = True)

    def save(self):
        img = Image.open(self.image)
        output = BytesIO()

        images = []
        tensors = []
        processedArrays = []

        tiffStack = []
        ###=============== Conversion ================###
        # Read tif, convert each page into arrays in images[]
        for i in range(img.n_frames):
            img.seek(i)
            images.append(np.asarray(img))

        # Read every numpy array, convert to tensorflow, process by dividing by 2
        for x in images:
            tensorX = tf.convert_to_tensor(x)
            processedTensor = tf.math.divide(tensorX,2)
            tensors.append(processedTensor)

        # Convert back to numpy array
        for x in tensors:
            processedArrays.append(x.numpy())

        # Convert to tif
        for x in processedArrays:
            tiffStack.append(Image.fromarray(x))

        img = tiffStack[0].save(self.name + ".tiff", compression="tiff_deflate", save_all=True, append_images=tiffStack[1:])

        # Save tiff file into model data
        img.save(output, format = 'TIFF', quality=100)
        output.seek(0)

        self.processed_image = InMemoryUploadedFile(output, 'ImageField', "%s.tiff" %self.img.name.split('.')[0], 'image/tiff', sys.getsizeof(output), None)

        super(TiffModel, self).self() 

I think the processing part worked well enough, but the actual saving to model throws an error everytime

Would you say the base64 approach would be effective to solve this issue?

[inland oak]

https://stackoverflow.com/questions/3748/storing-images-in-db-yea-or-nay

according to a bit of googling

base64 approach is not advised

they recommend continue storing just file paths

due to higher speed efficiency

But, that's not final answer, because NoSQL databases potentially can be good

some people who dealt with them should be asked

https://medium.com/@anilsingh.jsr/storing-images-in-blob-vs-file-system-3d704988e44e

https://www.reddit.com/r/webdev/comments/e0pgee/is_it_better_to_store_images_in_database_or/

[inland oak]

every discussion advises to follow the django ImageField path. storing image in filesystem and storing only metadata in database

there are some cases when it could be cool to store it completely in dbs, but highly likely it is not yours

[wind abyss]

I see I see

Unfortunately whenever I use the save method my django dies

[lusty wigeon]

I want to achieve this.. Which will be optimal way to do multiple forms? Also multiple files, email sending (have done already not difficult for me outside django, but does not have an idea to achieve in django in my context), pdf template for downloading report.. I am Django Beginner.. Kindly share some resources (short videos, or blogs) , ideas to do it easily (expert opionion), github repos (each part perfectly explained separately or combined).. Thanks alot in advance..

[inland oak]

it sounds like a mix of heavy frontend with a bit of backend

you should look into getting a hang of one of big three frontend frameworks: React / Angular / Vue.js

backend framework will add just login feature + ability to send by email

most of the heavy coding would be needed in frontend

I could recommend this book to get started in frontend basics 😉

And this one for javascript

After those two, getting started in Vue.js or React should be not a problem

depending on how you value your data safety about user logins and scaling, backend could be potentially a lot of work to do too, but that would be technically non essential for minimum viable product ;b

[lusty wigeon]

Ohh I see I though it is totally backend work.. I have done some work already but not satisfied with my results so asking here... I know html css, a bit.. But you shocked me that it is heavy frontend task.. But how can I manage multiple forms in context of django? by the way thanks for answering..

[inland oak]

you wrote in your specs ability for correct data. That can be made in backend too, but frontend will make it instanteous without requests to server and better? although better to validate data at frontend and backend at the same time.

but mostly, you wished to add multiple files... which if u wish to make a nice interface for adding them, requires again frontend

[inland oak]

Technically, you can do all of it purely in backend framework

where you need you can apply just a regular Javascript / JQuery, but you know... it will be a pain in the ass 😉

you will have far less capabilities to implement nice visual interactive interface
frontend framework will give freedom to implement all desired features at maximum

[lusty wigeon]

yes.. I was thinking here backend before but you guided me to frontend.. Although I think you guide me easy way (what I think).. A little bit of backend (no need of file validation except for file format which is not that hard)..

login is easy and done already in django.. the only issue was multiple forms and files.. which is I think easy in JS.. let me search for it on web...

Thanks you guided me well.. Thanks..

[inland oak]

u a welcome. although remember that even if login is easy and works out of the box.
you are restricted in those defaults to have just one working database without mechanisms to restore data in case of data loses

fine for minimum viable product, but a food for thoughts to think for scaling/data safety situations if necessary

[lusty wigeon]

yes.. django is easy in login and database sense.. just multiple forms is big deal in django..

[inland oak]

technically you could do it all with django 🤔

just page one: your first form

sending result to verification into backend and send back as sticky cookie

rendering form 2

inputting email and sending back to django

reading the cookie with data from form 1

doing stuff, sending answer

the only a bit I am unsure, how multiple files attaching works 😉 never needed it

bare bones functilnality but still a functionality

[lusty wigeon]

files in media can be retrieved..and then send as attachment..

[inland oak]

yes, nice introduction to javascript
and have a shame to be not distributing pirate copies here

[verbal pagoda]

@inland oak do they make some book like a brain friendly guide head first brainf or head first asm?
i want to learn asm....

[lusty wigeon]

yes.. he should share publisher's site.. it is pirated file..

[inland oak]

asm as in assembly language?

[verbal pagoda]

yes

[inland oak]

https://www.amazon.com/Head-First-Series-Books/b?ie=UTF8&node=8456760011
no, the closest they have to low level programming is C book as far as i know

[verbal pagoda]

hmm... it means asm is not brain friendly lol ok

[inland oak]

https://www.amazon.com/Head-First-Series-Books/b?ie=UTF8&node=8456760011 whole list of head first books

some of them became a bit outdated

[crystal siren]

Hi all,
I should do following task by python as a rehearsal:
"Create a load-balanced (public) REST API serving some json from an existing (loaded)
database and make it trivially easy to deploy on either AWS"

I don't know what does "load-balanced (public) REST API" mean!!? I would appreciate it if anyone could help me for understand it.

[inland oak]

usually people assume having API served at several machines (with assuming they have separate physical resources).
API served at machines should be exact replica/copy of each other.
which are having attached to them Cloud Provider Load Balancer object

Load Balancer will be standing on front of them, and distributing traffic between several machines

so Load Blaancer would be having its own Public IP

user requests your backend at loadbalancer public IP

and he is redirected semi-randomly to one of your replicated APIs

thus distributing workload on machines horizontaly

the task can be fulfilled in actually at least three ways

1. Most simple way:
   manually installing REST API at every server
   and raising load balancer as another VPS that has HAPROXY installed with config pointing to your REST APIs
   (Or optionally manually clicking cloud provider GUI to have cloud providers Load Balancer)

2. Smarter way:
   You use at Least Docker to install applications

3. Even smarter way:
   You use Ansible to auto install REST API and Haproxy load balancer as code from your development machine

4. Even smarter way further:
   You scratch the haproxy VPS and instead
   you write terraform code (or Pulumi or similar tool used), that raises cloud provider load balancer pointed to your VPSes with REST APIs

5. Even smarter way beyond further:
   You don't deploy your code on your own, CI tool like Gitlab CI tool does it for you, you just press a button to confirm production deployment if necessary, or no buttons is pressed, just code git commited to repository 😉

6. Ultimate way:
   Your terraform code creates Kubernetes Cluster
   REST API is auto loaded to docker registry by Gitlab CI
   Gitlab CI applies manifests to auto install everything into cluster
   Kubernetes auto creates providers cloud balancer

[crystal siren]

Thank you very much for your absolute explanation. 🙂 I'm familiar with terraform, ansible, docker, ... and totally designing CICD but in this case I don't know how should I create REST API by python

[inland oak]

so, you know tools just without kubernetes?

[crystal siren]

No I know k8s as well

[inland oak]

well, then use Ultimate way. 😉

All you need making dockerized python web application that gives at least hello world

10 code lines to do that + docker file

[crystal siren]

and dose it contain "... serving some json from an existing (loaded)
database" ?

[inland oak]

from flask import Flask
from flask import jsonify

app = Flask(__name__)

@app.route("/")
def hello_world():
    return jsonify("message": "Hello, World!")

it certainly contains serving some json

REST API is not assuming database usage

although wait

perhaps assumes 🤔

or not

no, no. mistook it with CRUDe applications.

[inland oak]

https://www.redhat.com/en/topics/api/what-is-a-rest-api#:~:text=A REST API (also%20known,by%20computer%20scientist%20Roy%20Fielding.
It looks like REST API assumes just having stateless JSON formatted application
So you should be good without database

[crystal siren]

Thank you so much for your help, 🙂 so I should start

[inland oak]

should be easy as pie for you. if you already know all the infrastructure tools 😉

[inland oak]

just make sure to serve your python application with gunicorn or something like that inside the container

and not with dev server

[crystal siren]

for sure thanks

[strange nacelle]

I'm using django, how do I specify the path from where to get the templates? It takes by default from Personal Account\templates\ and I need from Main\templates\ Help pleas

[odd belfry]

can you share template config from settings.py

?

[lusty wigeon]

Hi.. I want some html table editable with styles.. Which can communicate easily data with django... How? resources needed...

[crisp cove]

Hello everyone I'm new here! Name's Mike🏄‍♂️

[serene prawn]

Not really 🤔
Even with crud you don't have to store data, at least yourself 😅
Also i guess you can fire some kind of events via crud api? e.g. sending a push notification

[inland oak]

i mean, I thought CRUD is basically basic operations with database

creating / reading / updating / deleting those objects

it is a bit hard to imagine how can be CRUD without some stateful objects lifecycle to change

[serene prawn]

Yeah, but you don't have to store them yourself, your CRUD api could be a gateway to some microservice

[inland oak]

🤔 more proxies to the god of proxies.

[serene prawn]

Yep

[cerulean badge]

(django) is there any built in non negative validator for duration field?

For python web developers, didn't you need to understand networking?

[crisp cove]

good day everyone, please I want to know why this isn't displaying what's on my view. This is django by the way

[lavish prism]

Hey @crisp cove!

It looks like you tried to attach a Python file - please use a code-pasting service such as https://paste.pythondiscord.com

[cerulean badge]

you probably have improperly configured urls or raising Http404 inside your view

[crisp cove]

Thanks I've figured it out

[cerulean badge]

so what was the problem?

[strange nacelle]

I solved this problem/ Thanks

Rather, you forgot to add a link to the urls.

[ember adder]

Django project: I have a CBV to display information about a Volunteer object. In that view, I'd like to display a list of objects (VolunteeringJob) related to the Volunteer object. Each line in that related objects list will have a delete button. So I was wondering what's the best way to handle this?

My initial idea was to have a seperate view for VolunteeringJob and my information view would call its get to have the list, then call its delete to delete an entry and so on. Is there a better way/different way to do it?

[strange charm]

can someone help me with react + django?

i'm making a job portal

want to do stripe intigration

[unique shore]

React is a frontend framework

[strange charm]

i know that

[unique shore]

And stripe is something you would do on the backend

[strange charm]

yes

[unique shore]

https://youtu.be/722A27IoQnk

[strange charm]

i tried this

already

[unique shore]

Oh lmao

[strange charm]

i need some other logic

[unique shore]

you can search something up on google

[strange charm]

yes

[unique shore]

like “stripe integration with Django”

I can’t really help as I have never used stripe and have minimal react experience

But I do have some Django experience

[strange charm]

Can i ping DM?

[unique shore]

Sure

[strange charm]

Can you ping me? i'm not able to ping you

[unique shore]

Try now

[ivory lotus]

in python, I have the following code:
views.py

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('wall/', include('art.urls')),
    path('admin/', admin.site.urls),
]

and when I go onto there, it returns a PageNotFound. All the code is in wall/, but how would I redirect the user to wall/ once they enter my development server?

[marsh canyon]

im guessing this is your urls.py rather?

you can use django's redirect view for / the home page to redirect to /wall/

here is the documentation

https://docs.djangoproject.com/en/4.0/ref/class-based-views/base/#redirectview

lemme know if you face any problems regarding the redirect

this is be all you need
path('/', RedirectView.as_view(url='/wall'), name='go-to-wall'),

you can also give the pattern name instead of url

[whole garnet]

which is better flask or django?

[ivory lotus]

oh, yeah

Hello can someone help me in my flask project

i have a admin dashboard
in which students can post their complaints on the panel and on the home page of the panel all the complaints which student has posted will be shown there
and here i have two student for example
the main problem is .. when I post a complaint from first student account, then all the complaints are visible on the second student's home page also
i want complaints on home page of the user who is currently logged in
this is the problem

In simple terms - A student can see only their posts(or complaints) on their admin panel rather than seeing every student's posts

[glad sigil]

i don't think your issue is to do with flask itself. are you maintaining a mapping of userid-complaintid when you store the complaints? i.e. do you have a studentid column for the table where you store the complaints? you need to know which user posted which complaint in order to be able to filter that, right?

[feral night]

Hi, does anyone know flask and flask-sqlalchemy?

I have problem with proejct structure and database relations

[native tide]

I'm sure there are quite a few users that used both here

[feral night]

I want to have those files: app.py, config.yml, models.py for sure

Do I need database.py file?

also where should I include this db = SQLAlchemy(app) into app or models file?

[native tide]

I'm a bit rusty on flask web dev, but I'd say you'd put that into app file, if you're not thinking yet about directory structure

if you only have models.py file, I would not create database.py atm

[feral night]

and in app.py Im including modules.py by from modules import * right?

[native tide]

hmm. as a general rule, I think you want to avoid wildcard ('*') imports

[feral night]

ok, so just classes with tabels I guess

[native tide]

try to follow the documentation. that'd be my recommendation

[inland oak]

import modules as modules

is is in general safer import indeed

modules.stuff to use

[native tide]

I was recently asked about what's the best way to import stuff in python and I could give a straight answer. copied from pep8:

import mypkg.sibling
from mypkg import sibling
from mypkg.sibling import example

as far as I understand pep8 gives no preference to:

import mypkg.sibling
from mypkg import sibling

but which is better?

[inland oak]

what makes less mess in your imports ;b
while remaining precise what u use

prefering precise imports, using mass import as package to avoid too many imports

although import as package has advantage

over precise import

[native tide]

(np)

[inland oak]

because anywhere in your code, it is seen from which package the function is

so... I guess package import is good as general method

[feral night]

If someone has any good flask-sqlalchemy repo with modules, cofig and database relations repo I would liek to see

[native tide]

Darkwind, tnx

[native tide]

maybe this: https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

this may be outdated somewhat

but in general look to miguel for guidance

not certain, but I think he's also the author of the flask sqlalchemy extension

(altough, I may have read some critiques about it from sqlalchemy devs sometime ago)

@feral night ignore the link above

[feral night]

oh ok haha

[native tide]

sorry

my mistake

don't

I've seen this post: https://blog.miguelgrinberg.com/post/flask-mega-tutorial-update-flask-2-0-and-more

[feral night]

I just need a good guide how to connacthe files like: app.py, modules.py, this for sure: config.yml and routes,py

[native tide]

but it links to the post above

I just thought the post above was outdated, because it's dated to 2017

but it seem it's up to date

also from the first link thats dated to 2017:
there's metadata on the site like:

$ python3
Python 3.9.6 (default, Jul 10 2021, 16:13:29)

so it's been updated for sure

[inland oak]

my web development road started literally from this tutorial ;b

I was complete zero, and was given to implement everything from the guide within 5 days

[feral night]

so should I follow this tutorial or do Yo urecommend something diffrent?

[inland oak]

this is good tutorial 😉

[feral night]

ok thanks

[inland oak]

I was hired because of it

[native tide]

I'm not sure there's anything better for flask to be honest :)

(for a beginner)

[native tide]

👍

someone should mention to Miguel to update the date on the tutorial post

[feral night]

Do I need to import db here in routes.py?

from flask import jsonify, request

    }

    resp = jsonify(message)
    
    return resp




@app.route('/api/add-data', methods=['GET', 'POST'])
def submit():
    if request.method == 'POST':
        if request.is_json:
            data = request.get_json()
            new_label = label(label_name=data['label_name'])
            new_question = questions(question=data['question'])
            new_answers = answers(answers=data['answers'])
            
            db.session.add_all([new_label,new_question,new_answers])
            
            db.session.commit()
            return {"message": f"Data has been sent successfully."}
        else:
            return {"error": "The request payload is not in JSON format"}

# Get All Data
@app.route('/api/get-data', methods=['GET'])
def get_all():
    if request.method == 'GET':
        all_labels = label.query.all() 
        all_questions = questions.query.all()
        all_answers = answers.query.all()
        
        
      
        
        return jsonify(all_labels+all_answers+all_questions)```

and tables?

[carmine cipher]

Hello guys !! Please can someone tell me what best language for backend ?

[slate narwhal]

@native tide @verbal pagoda Thanks guys

[unique shore]

You can use JavaScript, c#, Python, rust, etc

[carmine cipher]

Thanks !! What your preference and why ?

[unique shore]

I honestly love c# and asp.net core

C# and the .net platform is growing in popularity and will definitely be useful In the future

It’s also really fun to work with

[carmine cipher]

Great !!

[carmine cipher]

Actually I was thinking to go with node.js or django .

[unique shore]

those are great options

[carmine cipher]

Definitely I will try node because I have strong background in JavaScript

[unique shore]

yeah great

good luck

[topaz widget]

lol

[indigo kettle]

what are we lol-ing

just that django is python?

I guess it is a strange requirement to have 1 year of python and 2 of django

[topaz widget]

If you have two years of Django, you have two years of Python. Not a big deal, just a little silly.

[indigo kettle]

yeah I see what you mean

I will say that it is very different to be scripting with python and writing a website with django

[topaz widget]

True. But if you have 2 years of experience with Django, doing scripting with Python should be no problem.

[native tide]

Finding someone that has done 2 years of Django without having done python scripting first in some capacity is like finding a unicorn. If you did find someone with only 2 years of writing Django code, I bet they would struggle to script things in Python.

It's much more likely that they started with Python scripting and then picked up Django so pretty hard to test the theory

[indigo kettle]

yeah I wonder. It seems like people try to jump into web development with django without having much programming experience beforehand though

at least from things I've seen in this channel

I feel like I've seen quite a few people just diving in the deep end

[native tide]

Django's ORM in particular is barely python

It's a language itself

[indigo kettle]

for sure

I feel like being good at django isn't about knowing python, it's about knowing all the class based views you can inherit from, how to write better sql queries through the orm, popular 3rd party django plugins like DRF and django-filter...

[native tide]

I've done a lot of Django the past couple of years, but still get to write regular python too which is nice.

[ember adder]

incidentally, it makes you a better architect in the end IMO

[ember adder]

I learned Python through learning Django which I learned through TDD with Obey the testing goat. I've got bruised quite a bit and wouldn't recommend it that much, but I learned a ton. I've never learned Python scripting before that at all.

[native tide]

I stand corrected. So was basic python scripting difficult when you tried it or do you think Django filled in a lot of that info?

[ember adder]

Learning and doing Django really taught me a lot of the Python basics: inheritance, list comprehension, using packages, testing, etc. I mean, at some point in a project you'll have to extend Django code using Python basics and advanced stuff. In my case it was very formative and I learned a ton on the side (reading two scoops, TDD, CI/CD, Docker, Ansible, Terraform, Git, GitLab products, Django-cookiecutter, SAST, databases, reading and understanding documentation, payment integration, etc.)

[ember adder]

I have to say that before that I had done C++, Java and C#, so I had some good bases on programming.

[native tide]

thanks for sharing, giant.

[feral night]

How can I get all data witch relations?

@app.route('/api/get-data', methods=['GET'])
def get_all():
    if request.method == 'GET':
        all_labels = Label.query() 
        all_questions = Questions.query()
        all_answers = Answers.query()
        
        
        result1 = labels_schema.dump(all_labels)
        result2 = questions_schema.dump(all_questions)
        result3 = answers_schema.dump(all_answers)

        
        return jsonify(result1+result2+result3)

Yeah, you pretty much made my point. If you're learning Django, it means you're probably trying to do something that can't be achieved with Wix, Wordpress, Shopify, etc..., and you'll have to write some custom code, which means you will probably be writing Python.

How do I write tests for websites?

[native tide]

Can someone please explain what does the scope attribute do i have a hard time understanding it. Thanks!

[wooden ruin]

there are a variety of libraries you can use to create testing with, like selenium, jest, and many others that are worth learning

[swift wren]

hey guys, what would websockets be used for in a CRUD application

[swift wren]

yeah thats a good how could you write comerical tests for a django crud application, selenium sounds good but how would that tie in terms of CI/CD

[inland oak]

popular web sockets application: Live Chats, for example Live Chat Support

[sacred cipher]

hey guys does anyone know how i can transfer AWS route 53 registered domain to cloudflare

because when i try to point the nameservers towards cloudflare, it never detects it

thanks 😄

[swift wren]

are these libraries compatible?

    - djangorestframework
    - django-cors-headers
    - celery
    - django-redis
    - django-celery-beat
    - django-celery-results
    - django-graphql-jwt
``` no matter if I don't know their functionality

[midnight musk]

Hi Guys

I am Bash

i made a project using computer visoin and AI

This is the link, can you guys reiview it and give me suggestions ?

[inland oak]

they should be. I dealt with everything except graphql

there only possible trouble I can see in

• djangorestframework
• django-cors-headers
• django-graphql-jwt

they all deal with modifying a bit requests (if to look just at names from afar), so in theory there can be some sort of trouble, so better to check 😉

[swift wren]

ah okay

hey mate

can you help me make a descion

is graphql better than rest?

apparently they can work side by side

but in a application that uses both, what kind of application would that be

[inland oak]

apply REST for simple stuff
apply graphql when you have complex input/output requests

[swift wren]

oohh

[inland oak]

i did not deal with graphql, but that's my presumption.

[swift wren]

thats very helpful

i dont think i would have many complex data commuinications

im gonna add in some statistics later on the application, but i wont have large quantity of data

[inland oak]

as far as I know graphql allows to make better granularity to requests.
in one request you can query data with multiple relationship between.... lets say model objects
and to receive output matching those requests in one go

so it could be efficient for stuff like quering data of Social Network profile type

[swift wren]

like make it faster when querying more tables

at a time

[inland oak]

I guess. We can get all data in one request instead of multiple ones

the proffit in faster request time there is indeed

that's just my assumption about how graphql works, I stil did not deal with it 😉

i was more spending time to learn how to do better infrastructure and faster development

still having a lot to learn

[swift wren]

lol, better infrastructure in Django xD

btw do you have any idea about redis/kafka/pubsec ?

a person told me i need a cache

[inland oak]

I use redis to implement Message Queue pattern through Celery in order to distribute workload of a heavy task horizonally into many servers

[swift wren]

oh wow, im also using celery

[inland oak]

I am interested to learn kafka next. It would make a nice architecture

[swift wren]

wait is redis even the same thing as kafka?

what is kafka do you know?

[inland oak]

as far as I know Kafka implements Event Streaming pattern, where we can send send events into it and attaching multiple backend listeners to the events
the difference is that perhaps it is possible to have multiple subscribers to one published event, probably

and that kafka stores those events in some different way probably

and just in general listeners are attached in a bit different way to distribute workload

.... basically my knowledge about kafka ends at 5 years old knowledge

wait a second

[inland oak]

http://www.gentlydownthe.stream/

xD kafka for 5 years old.

[swift wren]

aye yo

this looks amazing

how made this the heck

[cerulean badge]

I need to implement 2 timers for both chess players, this could be done with just setInterval and decrement the timer every second but it isn't accurate and tend to drift so we could instead calculate the timedelta from a datetime to the future called <white/black>EndDatetime and subtract current time from it, for pausing, we can add the timedelta of the amount of time the opponent spent on their move to <white/black>EndDatetime. and instead of doing all of this, I could use timer.js lib instead. now my question is, is it too trivial problem to use a lib? i think one could just use it and save their time.

[serene prawn]

Graphql is really nice to work with, you won't need to ask your backend team to, say, include some fields in a response, you can just query realtionships

[unique shore]

its not necessarily worse or better. graphql works on one endpoint while REST had many

[twilit needle]

I have had a few months of experience with graphql

There's a lot of things you have to consider when comparing graphql with REST.

Graphql offers a lot of benefits over rest, it exposes a typed and unified interface for your clients. You fetch exactly what you need with graphql. Which generally means you need to make lesser network requests with graphql

[unique shore]

ye but the hype around gql was kinda overblown

its definitely really good ,but i dont think it will be replacing rest soon

[twilit needle]

But practically, I would recommend REST over GraphQL for anything you use in production, if you want to build with python.

GraphQL was released in 2015 which means it's a relatively new piece of technology. Fewer people use graphql- so you have fewer guides and resources to learn from.

What are best practices? What should I do with x in graphql? How do I validate input data?

There's no right answer to this yet, and wont be for the foreseeable future. You have to figure out what works for you on your own.

[unique shore]

mhmm

[twilit needle]

The python graphql ecosystem is also not completely production ready, when compared to the nodejs ecosystem, though we have nice libraries like strawberry and graphene.

So IMO graphql in production is a deal with the devil

I spent a lot of months learning this.. lol?😅

What's qloom?

I couldn't find any related resources, sorry

Could u link some

And also I dont think this is the right place for adverts

[violet mesa]

If I have an api that fetches some data from another API for some features but otherwise does everything by itself (interacting with presentation and data layer), is it still a technically a gateway api?
eg my zoo api fetches images from dog, cat api before returning it to zoo.com

[radiant garden]

probably not

most web services use some sort of other service, for example a database

[violet mesa]

Yeah, i need to write a report so I was wondering if gateway is correct usage here, thanks for the clearup

[cyan ivy]

hm what's graphQL?

[dense slate]

An API query language.

[twilit needle]

It's going to take years for it to replace rest

[unique shore]

like sql

they are both query langs but not the same thing

[dense slate]

It all depends what you want I suppose. I don't know if it has to replace it necessarily.

[cyan ivy]

Hmm

[serene prawn]

Why not use both? 🤔 I heard some companies use graphql for querying data and rest for mutations

[dense slate]

What's the point of using two?

[grizzled coral]

Hello

[serene prawn]

rest has established patterns for, say, permission checks, validation. I don't see why won't you use rest with graphql if you want to

[golden bone]

What do you expect to happen and what happens instead?

My guess is the problem is with your crud but you haven't shown the code for that

[grizzled coral]

Nothing session created

[golden bone]

It's such a pain to get Selenium working in most environments, especially if you're not doing it headless. There is a Docker image, that's the most reliable solution I've found

[dusk portal]

how can i make a dm chat feature in django

i guess i

will need django channels

websockets

[opaque rivet]

yep

[wheat verge]

can django projects be deployed in netlify

[grizzled coral]

Docker can get download files automatically?

[golden bone]

Docker is just a tool for building containers, you could try running that Python code inside a container with headless Selenium if you can't get it working otherwise. I personally find that easier then fighting with Selenium, but if you've never used Docker before either I don't know which path will be easier for you

[golden bone]

Maybe, looks troublesome though https://answers.netlify.com/t/can-i-deploy-django-on-netlify/8783

Maybe try this instead https://help.pythonanywhere.com/pages/DeployExistingDjangoProject/

[wheat verge]

yup i have read that it aint straightforward like it is for static websites

I basically want to receive a file over an API endpoint and put it on S3

[serene prawn]

last_build_date = Column(DateTime, default=datetime.now()) your default is incorrect, you shouldn't call now here
You can use Enum(native_enum=False) here, it would store your enum as a string

[atomic dome]

Hey, I am a bit confused about how to proceed. Should I learn vanilla Django before going into REST framework?

[native tide]

If you don't plan to use templating, just skip the views/templating parts and move to REST framework for those. Routing and models is basically the same across the two paradigms.

[serene prawn]

In your case it would be whatever datetime.now() is at the start of your program, you can pass it a callable:
https://docs.sqlalchemy.org/en/14/core/defaults.html#python-executed-functions

e.g. datetime.now without parenthesis ()

np, i'm also learning a lot - i didn't know about this https://docs.sqlalchemy.org/en/14/core/defaults.html#computed-columns-generated-always-as

[slim cape]

Thank you!

[scenic furnace]

Is there a better way to do password input than just making an HTML form and password type input?

It's slightly concerning that this method just dumps the password into URL parameters and queries the URL specified in the form's action parameter.

[native tide]

Shouldn't be in the URL parameters on a POST, and hopefully you're sending over HTTPS

[scenic furnace]

HTTP for now, I don't own an SSL certificate

Also I am not setting any info up for real, only test info.

[native tide]

HTTP if running locally in dev or even on a server without any important information is fine. POST should move it to the request body instead of the URL. Then, when you're ready and need to secure it, check out LetsEncrypt for a free SSL cert for HTTPS.

[scenic furnace]

awesome

[scenic furnace]

Oh my goodness, thank you so much for pointing me to Let's Encrypt!!!

ok, so here's what I have on the HTML side:

<form method="post">
    <label for="username">Username:</label><br>
    <input type="text" id="username" name="username"><br>
    <label for="password">Password:</label><br>
    <input type="password" id="password" name="password">

    <input type="submit" value="Log in">
</form>

My route for this page:

@app.route('/login', methods=['GET', 'POST'])
def loginPage():
    print('serving login page')
    if request.method == 'POST':
        print('login request with form data {}'.format(request.data))
        return render_template('login.html')
    else:
        return render_template('login.html')

For some reason, the request.data is empty, why?

oh doi 😆 flask leaves that empty if other mimetypes succeed...

[slate narwhal]

Anyone know what I'm doing wrong here? align-items: center; isn't working for me

[lavish prism]

Hey @brave compass!

It looks like you tried to attach file type(s) that we do not allow (.html). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

Feel free to ask in #community-meta if you think this is a mistake.

[brave compass]

I got this working while reviewing this Stack Overflow link: https://stackoverflow.com/questions/5995405/how-to-center-a-navigation-bar-with-css-or-html#

[slate narwhal]

The links in the navbar all got centered when you entered that into CSS?

Hey @brave compass!

You either uploaded a .txt file or entered a message that was too long. Please use our paste bin instead.

[brave compass]

Yep. Here's my file: https://paste.pythondiscord.com/makovoqeme.xml

I left out the background coloring. If it's still not working then maybe it's something with the viewport (though that'd be weird).

I want to send a link in email which is going to trigger a get method. It is working perfectly in postman like that. But how can I include those headers to my link?

I tried like that:

myapi.com/createBulk?email=[e-mail]&x-functions-key={myKEY}&Ocp-Apim-Subscription-Key={myKey}

But it gives me this error:

[indigo kettle]

how are you sending the request, with the requests library?

[static zealot]

I am trying to send this request with a browser, the api is running on server.

[wide anchor]

I’m a self taught developer, and I feel like I’m missing something huge.

I’ve been through some Udemy tutorials, built real world projects for my business, and worked with JavaScript and python for about a year now, but I feel as if I’m still missing something from my education of front end development. It still seems complicated to me and like I just don’t “get it”.

Process goes like this:
Have problem that’s needs to be solved, or idea —> find a similar tutorial—> make a extremely rough plan in my head —> build something with a roll of duct tape and stack overflow —> repeat

I almost feel like I can program but don’t understand computer science.

What books, guides, or articles can I read that talks more about theory and larger topics, beyond just a tutorial of “how to use x framework”? How can I start to see the big picture?

[native tide]

@wide anchor Find a problem you want to solve, then determine if what you already know is sufficient to accomplish it.

Realworld problems are the best problems to solve.

[stark tartan]

Yeh boss

[indigo kettle]

you don't set headers in get requests created by browsers. So you cannot. You can use javascript and do a fetch and set the headers that way but you can't do a simple copy and past of the url into the url bar

[stark tartan]

Programmer don't ask such questions bro 😅 😫

[stiff totem]

In django + postgresql how can i get today's, tomorrow's and then next 7 days records respectively i mean, group them and get with annotation or something

[native tide]

"my business" << This is good as there is no one to fire you, you are free to try new things and implement them as you see fit @wide anchor

I envy ya 🙂

[indigo kettle]

what does this mean

[stark tartan]

Pro talks bro you can't understand🤣 🤣

[indigo kettle]

I've been doing web development for about 6 years now and I feel like I'm only finally getting more of the big picture. It's mostly just been like you're saying, finding problems and panicking while searching for solutions that I don't understand

just keep looking things up and reading

[wide anchor]

Yea being the owner is great for sandboxing problems, but when it really comes down to it, I really want to be a better coder

[stark tartan]

Ohh that Great

[native tide]

So what do you want to accomplish first? What's a 30 second elevator pitch on the thing that needs solving @wide anchor ?

[stark tartan]

If you have some small work give me

[wide anchor]

I need to understand the principles of web development to make an archive of videos for my clients

[native tide]

An archive of videos can be telnet.

Why do you need principles, go quick easy fast, unless you want flash.

Do you want a problem to solve because you're bored, or a problem to fix because you need a solution.

[wide anchor]

Like:

How many requests to the db is too much?

Do I store the data in a local store (vue js) or do I fetch the data each time?

Other things like this

[native tide]

Depends on your DB and the popularity

Local, perhaps.

[stark tartan]

What is DB bro

[native tide]

Again, you sound as if perhaps youre searching for an unsolved problem.

sqlite3 or postgresql

[wide anchor]

No, it’s a feature upgrade for my clients on a non-software based company. I just love to code so I’d like to code the solution so I can also learn more

[native tide]

You don't need django if flask works just fine, or perhaps python3 -m http.server even.

I love to code too; it's a great hobby of mine.

But I don't search for problems, i search for ways to solve problems using python and semi-maybe-mostly niche things.

i.e.

[wide anchor]

I don’t think there even needs to be a server component - just vue js and the database is my thoughts

[wooden ruin]

but if you have the time it's definitely worth going under the hood and getting all the tiny details about a particular subject,

[wooden ruin]

also, you should at least have a basic web server for an API to your database - the frontend should almost never talk directly with a DB.

[native tide]

^

Let me ask you a question there biz owner.

Do you use Excel at work?

[wide anchor]

So I’m fetching about 1800 records in a firestore db each time the user loads up the site - and then the user will navigate using the sidebar to each video component - I was thinking it would be silly to refetch a video from the db if Inalready did

[wide anchor]

Hourly

[native tide]

Ok.

CSV or XLS(X)?

[wide anchor]

So process flow is client request —> server —> firestore ?

[wide anchor]

Google sheets

[native tide]

yuck.

But ok, xls.

Is it formatted all pretty?

i.e. Do we need formulas?

[wide anchor]

For what ? What are you referring to here ?

[native tide]

The google sheets

do you have formulas in them pointing to cells within the sheet.

i.e. Can we export as a csv and do this better, and without uncle G looking over your shoulder.

If youre doing hourly Excel work, you're doing it wrong....

Excel is an output format only; executives and above.

So many companies, they do it wrong; painfully so. Oh the horrors......... =/

[wide anchor]

For this specific project, there is no google sheet. Just a folder of sub folders containing mp4s that need to be progmatically uploaded to Vimeo and stored in my db

What would this look like at a high level example ?

[native tide]

What kinda db; something on aws maybe?

[wide anchor]

Fire base

[inland oak]

oh, you are wishing how to plan the process of developing programming product. planning the project in a... more industrial way.
System Analysis & Design comes to rescue
it teaches how to select projects, how to set requirements what needs to be done, how to design its use cases / scenarios from user view point, how to design data flow diagramms out of it, how to plan database model objects and how to design implementations of them, how to plan UI, how to plan efficient code structure by modules/packages for implementation and finally processing to implementation stage.

[wide anchor]

Amazing, so this will teach me the DESIGNING aspect of programming right ? But I would still need an “implementation” guide correct ?

[inland oak]

mm yes, it teaches you how to design projects
But essentially it just give you sight how to do in a bigger picture
In order to design well technical parts you need to have a broad and deep understanding of core technologies
in order to design UI, you need to learn how to use tools like Figma for designing and all the reading how to plan interface in human friendly way
in order to implement / planning how to code well, you need to cover at least basic topics like:
Head First Design Patterns
Clean Code by Martin
unit testing principles practices and patterns (by Vladimir Khorikov), TDD
domain driven design by Eric Evans
and e.t.c.

Writing clean efficient code structure obviously requires learning different programming aspects how to do that
and all related good practices to it. Unit testing makes it the most amazing btw 😉
Well and obviously coding well requires a lot of practice. Books are just a knowledge that needs to be practiced in order being useful.

The System Design book just gives you plan how to that in a scope of industrial project. It does not make you an expect in every specialized field to do it in the best way

[wide anchor]

Ok this is awesome - thank you, so by reading these books I could use the principles taught in them to write better, more efficient code for web development ?

[inland oak]

Surely. i am web developer as well

[wide anchor]

Awesome - I’ll dive into them. Thank you 🙏

[inland oak]

u a welcome. Btw, I went through university up to Master Degree but never was taught anything like this ;b Well technically i was, I remember going at least through one chapter of System Design
but basically I needed to self learn all of it after university too

[wide anchor]

We’re these the most helpful books to you in your journey of self taught programmer ?

[inland oak]

I love books, but books alone could not be helpful.
The usefulness was in reading books, asking advices here and in DevOps discord server and even in frontend discord server, and applying everything at practice at work everyday 8+ hours.

System Design and Design Patterns are sure memorably useful reading out of all of them

but it was just one among many.

I would stress again that learning Testing gives the best proffit in writing better code in a short time

in combination with a bit of DevOps tools like Ci/CD pipeline, Docker and e.t.c. it gives me the fastest development speed

without losing quality

[wide anchor]

Good to know, I’ve always dreaded testing and ignored it hahah

[inland oak]

I would be lying actually that saying just a bit of DevOps tools are necessary.
Actually all of them are needed to reach full happiness. to have Infrastructure as a code.

My process of development reached a stage where
Once I submit code to repository
It is auto build into docker container by CI/CD pipeline
runs unit tests
redeployed fully automatically with whole infrastructure (servers and e.t.c.) into staging environment
it runs integration tests that all microservice applications part work together in unison
and then saved as ready for deployment in one click to production

[winged pendant]

Hi everyone, has anyone had a problem trying to connect MySQL in django 4.0 using macbook pro with M1 chip?

[inland oak]

Speaking of planning and architecture
being good web developer requires learning stuff like that too

[primal quartz]

Hello, I would like to start developing a website but dont where to start. Is Django better or Flask?

and if so any tutorial suggestions?

[inland oak]

planning stuff in microservices makes it planned for bigger scalability
and just having easier / smaller code in independent parts. Makes stuff sort of... quite easy, simpler.

it brings its own set of problems though

But higher level infrastructure tools resolve them

[wide anchor]

This is all awesome stuff, thank you for all of this - have a huge pile of books to go through now hahah

[inland oak]

xD (looked at my own huge pile of books waiting ahead of me, the road never ends)

[primal quartz]

?

ill start with flask!

[inland oak]

and just going faster due to having everything out of the box

[primal quartz]

thank you for your help

[inland oak]

Good choice
https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

highly recommend this tutorial.

it was recently updated to flask 2.0

[primal quartz]

Great!

ill get started right away!

This is a huge help you guys thank you so much

[burnt cedar]

hello I was thinking of getting into web app development but Idk what roadmap should I choose

I will prefer if its related to python libraries like django or flask

should I just go with full stack course python oriented?

[inland oak]

btw for roadmaps: https://roadmap.sh/
considering that you ask about it in python Discord server, you are going to receive the most biased answer:
I think starting from python backend is the best option in terms of getting fastest development with being introduced to core programming concepts better
frontend is just not giving the same best practices efficiently IMO.
and switching from backend to front should be easier that from front to backend.
and I am biased to frontend 😉 even if i cared to learn/practice it

[burnt cedar]

ty also any paid/free tutorials for this which u recommend

because I am looking for all in one thing

which teaches pwa , frontend , backend (with python)

[inland oak]

So you aim to be developing frontend and backend separately?

frontend in frontend frameworks, backend in python?

it is impossible to learn everything in one thing.

I can recommend starting from Flask or Django
https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world
https://docs.djangoproject.com/en/4.0/

with moving into
Flask Restful
or Django Rest Framework https://www.django-rest-framework.org/tutorial/quickstart/ for those purposes

[burnt cedar]

yes like I was checking some bootcamps for "full stack development" in udemy

[inland oak]

bootcamps teaching full stack are usually a lie 😉

[burnt cedar]

oh

[inland oak]

for Frontend I would recommend React / Angular or Vue.js
Vue.js should be easiest out of them
To get started in frontend learn HTML/CSS first, this book is amazing

Then progress into learning Javascript

And then start doing Vue.js from docs
https://v3.vuejs.org/guide/introduction.html
and getting advices in Vue community
https://discord.gg/vue
Optionally getting started from book as well
The easiest way to setup Vue.js project, is Vue Cli 5 tool
https://cli.vuejs.org/
it will setup everything with SASS and e.t.c.

[burnt cedar]

thanks

[inland oak]

mind you, that you are just learning frameworks and nothing out of programming concepts in those materials

[burnt cedar]

mhm

[inland oak]

bad code would be for sure 😉 u need to learn more than that if you wish to be good

[burnt cedar]

👍

[wooden ruin]

have you messed around with Vite? i've used both and was wondering if you had any preference between the two

[inland oak]

Initially used during starting docs, and then abandoned in the favour of Vue Cli 5

Vue Cli 5 was setting me up everything from zero to fullest capabilities, including how the f*** to do testing, and offering in CLI interface all tools for all categories with bolierplated code.

I did not really learn how to do the same in Vite

I guess i missed that if it can do the same too

[wooden ruin]

Yeah i think you're right about vue cli having alot of good boilerplate code with everything you need to ready to go, setting up things like vuex or vue router is a real pain with plain vite. thinking of going back to vue cli 5 even if it means slightly slower build speeds.

[strange charm]

can i save form data before entering into the database. Means i want to save the form data and i want to create a entry only if the payment is successful.

django + react

[strange charm]

yes

stripe api

but how can i save form data. I can save the api data from stripe directly.

[rotund perch]

Heroku/Django
I Had an SQLITE configurations on the settings.py, why is this not working? Ive also changed the ENGINE to postgres in the config vars

This is my django settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

[strange charm]

So, suppose i have a job model. How can i call this job model? after the payment is successful? means i understand that i can use the data and store directly into my database. But what about the data which i need from the frontend form? How can i call that data after the payment?
because customer data will be provided by stripe
so its easy to save directly.
so for example: I have name, age and address. I want to save this data from the frontend after the payment went through.
maybe wrong example.
suppose i have job title, salary, fulltime, location data. How can i save this data? this data is different from stripe api data.

[tribal tapir]

Hello im trying to upload from my front end to my back end server with flask

and i have an issue

that when i pass the file i dont get the file to my back end i get an empty ImmutableMultiDict([])

[thick sinew]

If I update Jinja without updating django will it create problems?

[inland oak]

As far as I know Django uses its own templating language by default.

So updating Jinja should be completely safe

[thick sinew]

thanks

[vital harness]

Someone know what should I use for parsing a database from a website? I’m working with python

[inland oak]

that sounds weird. Could u rephrase what you are doing

[cyan skiff]

hey guys. Im new to this field. Can I create a Python website with a personal account where the user can find only the information that I allow?

[vital harness]

Sure. So, I have a school project and I need to look through prospects of different types of drugs to search some keywords in order to find an interaction between drugs. And I’m working in python and my professor told me that in order to do that I could use a method called parsing. I don’t really know what that means so I was thinking that someone can explain or give an example or so.

[inland oak]

in which form he gave you information about drugs

how your source of data looks like

[vital harness]

He told me that I need to extract data from a database in which I can find all this prospects. I’m still looking for that database because I have to do it for my country specific and it is quite difficult to find here.

[inland oak]

how the database looks like

was it given to you

[vital harness]

Nope. And I don’t know yet how the database looks like because I couldnt find it yet. I was hoping that I can least find what parsing is

[inland oak]

parsing can be done in different ways, since you don't know how your database looks like, it is impossible to say which method of parsing you need
I would assume that you will probably find database in the form of csv documents with data separated by ,

highly likely all you will need to upload database, just reading lines and applying split function by delimiter 😉 it depends on how it is structurized

technically there is so called web parsing, but i think highly likely, you don't need it

[vital harness]

Ok, I understood. Appreciate your help

[polar gull]

Hiii. I am currently building a notes taking website with django, pretty basic one. I added the note creation and deletion functionality succesfully and also added the login authentication functionality. But there is one thing i am struggling with. I want to show a user only his notes not every else note that exists in the database. Any idea how that might be done. How should i design a model or write a view for that. Would really appreciate the help.

[dense slate]

You need to send the user's information in the request to the server to then pull the objects with only that user as the author.

usually your function is like def notes(request):

the request holds that user information

[cerulean badge]

I am using 2 datetimes to the future called deadlines, and use it to calculate the times remaining for the timers for both players in chess. I get that deadline in isoformat from server after every move is played. my question is how accurate are 2 devices time when they are set to automatic date and time?

[dense slate]

Wouldn't the times always be posted according to server time? So it should be 100% accurate I would think, unless I'm misunderstanding the question.

[grizzled coral]

selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist

[cerulean badge]

i give the datetime of deadline when the time will end and use current time on that machine to see how much time left every x milliseconds

so there will not be any latency issues

[dense slate]

Ah, no idea, might be a good question for game dev.

[grizzled quartz]

also have cname record for api

[native tide]

Would I be able to ask a question about relative paths here? (html+java noob)

[dense slate]

I think this is more python focused but we can try to help maybe?

[lucid vine]

How come my new site is loaded perfectly fine inside postman, but in browsers I get ERR_CONNECTION_CLOSED

DNS is set up...

wait, do .dev sites require HTTPS? ...

[dense slate]

They don't, no.

Or wait, I mean working in dev, meaning locally, doesn't.

You getting any kind of more specific error than that?

Is that when you're fetching data?

[native tide]

I asked in a help channel, but it ended up going dormant!

this assignment is purposely meant to have unorganized files, with the intention of us using ..\ to get the img src to work! I was able to fix the navigation id from character page.html to go to index.html using ../../index.html

But I cant figure out the img pathing

[inland oak]

\ path is not valid linux filepath format. the end of the story.

[native tide]

I'm sorry, this is my first week of the course (and im learning remotely for the week due to being sick)

can you explain that a bit?

do you specifically mean the backslash?

[inland oak]

as far as I know browser paths can be possible only in two formats
Absolute and Relatives

absolute - /src/blabla.jpg
relative - blablabla.jpg
relative - ../blablabla.jpg

it is not possible to have \ file paths for web site

[native tide]

oh that path isn't to a website! It's a relative path leading to a local image file

[inland oak]

unless perhaps windows filesystem allows it for local file paths? 🤔

[native tide]

yea!

[inland oak]

u use it in HTML language

HTML usually means web site 😉

[native tide]

file-paths-incorrect\main-images\header-images\neit_logo.png would be the full relative path

but it doesnt work since character pages.html isnt in a shared folder so we need to use ..\ to get it to work

(we arent allowed to move files manually, since the sake of the assignment is the pathing)

[inland oak]

in order to find correct relative path...

as far as i understand u a using plain HTML without frameworks, right?

just open console in the folder of your HTML file that has links to images

[native tide]

uh correct, for example

<main> <header> <img src="..\..\..\main-images\header-images\neit_logo.png" alt="NEIT Logo"> </header> <hr> <nav> <a href="../../index.html">HOME</a> | <a href="characters page.html">CHARACTERS</a> </nav> <hr> <section> <h2>Monsters</h2> <img src="images\monsters\alien.jpg" alt="Alien"> <img src="images\monsters\godzilla.jpg" alt="Godzilla"> <h2>People</h2> <img src="images\people\macho man.png" alt="Macho Man Randy Savage"> <img src="images\people\mrt.webp" alt="Mr T"> <!--Image with absolute path--> <img src="https://vignette.wikia.nocookie.net/monstersincmovies/images/0/09/Sulley_002.jpg/revision/latest/scale-to-width-down/340?cb=20130512141939" alt="Sulley"> </section> <hr> <footer> <img src="..\..\..\neit-tiger.png" alt="NEIT Tiger Mascot"> </footer> </main>

[inland oak]

and find a path by hand from current HTML template to images

or by console

cd ..

dir

commands movements 😉

[inland oak]

basically images need to be accessed relative to location of your HTML file that has the links to them

well, or just using absolute paths, which would be easier. but since assigment is not allowing it, lets do it relative 😉

[native tide]

yea we have to do relative, and we can't move files/folders. I have to have the neit_logo.png img src to display in the character page.html file by changing it's directory path using ..\

Is that what you're trying to explain?

[inland oak]

file-paths-incorrect/main-images/header-images/neit_logo.png
pages/characters/characters page.html
?

assuming trying to find path from this html to png

../../file-paths-incorrect/main-images/header-images/neit_logo.png

it will be basicallly something like this

.. - means going to parent folder

we moved twice to parent folder

and then moved to subfolders of going to png

[ocean slate]

u got ur answer bhai?

[native tide]

yea for example I did ../../index.html for a navigation link to go to index.html from character page.html

[inland oak]

btw, i would highly recommend renaming characters page.html to characters_page.html

[native tide]

not allowed

[inland oak]

it just looks so gross with space. not sure why

[native tide]

it's a pre-coded assignment

we're only changing the paths for images

[inland oak]

okay, %20 I think will work instead of space

browser can escape spaces

[native tide]

oh my gosh I fixed it. I see what you were trying to explain.

Original relative path: file-paths-incorrect\main-images\header-images\neit_logo.png

fixed: ../../main-images/header-images/neit_logo.png

I was doing this the whole time:

..\..\main-images\header-images\neit_logo.png

I didn't realize I that I was allowed the change the backslash to a forward one... 😰

[dense slate]

I can't think of a situation I ever use a backslash in web dev.

And I've worked on both linux and windows machines.

[lucid vine]

they do

as soon as I fixed https it started working

chrome & firefox enforce it

[dense slate]

Yea, I thought you meant working locally in a dev environment.

[lucid vine]

nah, .dev tld

which is really stupid if you ask me

[dense slate]

🤷🏼‍♂️

[lucid vine]

like why does a .dev need ssl enforced??

especially when devs tinker with stuff

[dense slate]

That's surprising though, because I've been told https is only really necessary for websites using sensitive information.

[lucid vine]

why not enforce it on other tlds then

[dense slate]

That http isn't a problem otherwise.

[lucid vine]

well... yes and no

you should always use https these days

[dense slate]

should, sure.

[lucid vine]

unless you are developing some micro services

for internal use only

but then I recommend gRPC

everything should use ssl

I hope dns over https becomes more widespread too

[dense slate]

But .dev specifically enforces https?

I didn't know any of them enforced it

[lucid vine]

yeah, the dumbest thing ever

chrome won't open .dev in plain http

it refuses

lol

same with ff

I was like wtf why curl works but chrome errors out

just google things

[dense slate]

Oh I see, google bought it and now redirects traffic to https in chrome.

[lucid vine]

if I knew that I would never buy a .dev domain

live and learn I guess

[dense slate]

Is there a benefit to the .dev domain? Instead of dev.yourdomain.whatever?

[lucid vine]

there ain't any benefit to any tld over the other really, except name and SEO

but I wanted a .dev for my personal website

[native tide]

I was wondering do people Still prefer website which are made from html ,css,js considering the fact wordpress Exists?

[lucid vine]

lmao

[dense slate]

Yea, much so.

[lucid vine]

I can count 10 reasons at the top of my head

first of all PHP

second of all WP

it's all shit

[dense slate]

You can't build an advanced custom web app in wordpress.

[lucid vine]

you can actually but it's hell

[dense slate]

Yea WP is really slow.

[lucid vine]

and WP uses that same tech (HTML,CSS,JS)

so it's basically just another framework

but for beginners

a "CMS"

[native tide]

Because nowadays people make website using wordpress( probably earn good amount too) then label them as web developer so I was just confused.

[lucid vine]

naaah, publishing a WP site ain't web dev

it's like writing a blog

lol

if you write custom wordpress plugins and such then you are a dev.

[dense slate]

Yea I've seen plenty of web dev job advertisements where they use wordpress. I suppose technically, sure you're developing a website, but you won't get any advanced apps coming out of that. At least I don't know of any.

[lucid vine]

At my last job we had a lot of WP sites that were very customized

I hated it all

but publishing content for WP ain't web dev.

they probably just use it so they put it in an ad

at the least you should be comfortable with PHP

[snow edge]

I have a few images in my html file with <img> tag. When I load the html in flask using render_template, everything else gets loaded instead of the images. Can anyone tell me how to fix this?

[daring pollen]

just getting started with django, I kinda get the basics and working on a site to display content, how would I go about (or what should I search for) daily querying a site to refresh data for the app?

going to look into django-cron but open to other suggestions

[scenic furnace]

I am making a Flask web app. What's the best way to update the contents of a page every second or so?

[drifting radish]

Can i create game in unreal engine and put this on web?

[wraith dagger]

Celery are good for background tasks, but it might be complex for this case (I mean it requires extra process (worker), looks superfluity for only daily query)

Maybe u have to check Django Dramatiq, but I haven't had experience with this

[golden bone]

This is asked frequently, please search the channel

[scenic furnace]

ok

hey guys!

I'm having a strange problem with flask sql alchemy, please check if you can help me, I'm stuck

How to create a many-to-many relationship with 3 tables using flask-sqlalchemy? the default docs only work for 2 tables, not 3.

Thank you!!!

the result of the table would be
id | table1_id | table2_id | table3_id

[dense slate]

Maybe the M2M could relate to a through model that has 3 FKs?

I'm not quite picturing the scenario. Can you describe how the models would interact?

[scenic furnace]

Ok so I'm using Flask's session plugin and need to test having multiple users logged in at once. For whatever reason, I can't use my phone for this because my college's network is set up funky and my phone can't see my laptop. Is there any way to isolate two Firefox instances to allow me to do this?

[indigo kettle]

start an incognito session

[scenic furnace]

good idea

thanks, it worked!

Does flask-socketio respect flask-sessions or do I need to do funky stuff for that?

Hi, I'm using Django and I have this function on one of my models

def diferencia(self):

    return dif

and then using it on a template to show the rating of a post, but I wanna make a query which order the posts lists using this rules of likes-dislikes but I don't know how to do it

posts = Secret.objects.order_by('likes')[::-1]

and this is my query right now but I don't know how to make the query properly

[uneven bloom]

Guys can I deploy flask app on a local machine. It keeps crushing when I ran it in development mode for a longtime example after 2 days whereby it a method that runs in the background after every one minute.

[indigo kettle]

you want to use https://docs.djangoproject.com/en/4.0/ref/models/expressions/#f-expressions and annotations

probably something like py qs = Secret.objects.all().annotate(diff=F('likes') - F('dislikes')).order_by('-diff')

[inland oak]

probably reading something about REST API

I was trying to create a login system using django

but when i try to log in

literally nothing happens

i thought maybe what if it doesn't even receive the username and password, and that is what is happening according to me

it returns None None

so can someone help me in figuring this out

[north mantle]

lets say we have a json first time we cache it.. second time we gonna cache it it has changed, now how can we get only the new data. Mind that some been replaced, or been deleted

[rotund perch]

Hello,(Django rest framework) does anyone knows how to send custom errors to the frontend. I know (try-except) and if (except) return a Response, but does that returns that response if theres a 500 error when requested for the frontend?

[north mantle]

{"clips":[{"name":"18758979.mp4","time":"48 minutes ago"},{"name":"987654.mp4","time":"46 minutes ago"}]}

maybe i can just pull name, and somehow save a list of the latest one, if its not same then == new item

[wild iron]

from django.contrib import messages
messages.success(request, 'Your Message has been sent!')```

Something like this i guess

[rotund perch]

but thats on django templates I think right?

[inland oak]

with setting caching in python framework at Redis caching level, you can setup any type of cache validation rules your imagination allows https://pypi.org/project/redis/

[twilit needle]

So.. I have a small question

It's related to naming actually

[inland oak]

from rest_framework.response import Response

@api_view(["GET", "POST"])
def get_ping(request):
    return Response({"message": "pong!"})

if u wish sending error, just change response to have appropriate http error status code

return Response({"error": "my custom error"}, status=400)

or if you wish even more clarity and following best practices

import rest_framework.status as status_codes

return Response({"error": "my custom error"}, status=status_codes.HTTP_400_BAD_REQUEST)

[rotund perch]

Thats clear, Thanks!

[twilit needle]

I've got my flask views like this:

app = Flask()

@app.route():
def create_todo():
    return _create_todo(...)

def _create_todo():
    # service function
    pass

Here I've got a naming clash between my services and routes. Is there a better way to name them?

Please ping me when help!

[serene prawn]

You could encapsulate your logic into a Service/Command class

e.g.

class CreateTodoCommand:
    def __init__(self, session: Session):
        self._session = session
    
    def execute(model: CreateTodo):
        ...

@route
def create_todo(model: CreateTodo):
    command = CreateTodoCommand(get_session_somehow())
    command.execute(model)

For simple crud service would probably be better but i'd use command if you have some complex logic

[native tide]

Hello folks,
I currently have a flask app deployed on pythonanywhere and I want to add celery to the arsenal, but since pythonanywhere has no support for that, i need to migrate.
What are the service I could use that would provide a server for the workers and a redis broker ?

[serene prawn]

I think you can go with any vds

[native tide]

The thing is, I won't be migrating the flask app from pythonanywhere, I just need to distribute the tasks so I'll need a remote broker as well.

For the flask app to be able to send the tasks over to Redis

[serene prawn]

You still can host your services anywhere, but it think there are managed solutions too

[native tide]

Exactly, I'm asking about those managed solutions.
And if anyone has any recommendations, etc...

[ivory lotus]

#help-candy please

[serene prawn]

I'm just saying you don't have to use a managed solution since you can just run redis on a vds

Didn't have any experience with managed redis and other services, so i can't recommend anything

[native tide]

Alright, thank you !

[native tide]

I have another question here, if I get a VPS/VDS instance for example on provider X, how can I hit the local redis instance from my flask app ?

[serene prawn]

Well, it's not local if redis is on vds and your app is on pythonanywhere 🤔

[silk dove]

Thank you very much

[inland oak]

just raise redis with docker/docker-compose at this VPS

and it will become local to your flask app (for easiest setup I would recommend putting flask to docker-compose too, so it would be right in the same docker network, which will make domain address to access redis, same as the service name in docker-compose)

[twilit needle]

I'm actually doing this currently

Wondered if I could have plain service functions

[native tide]

That requires migrating the flask app from pythonanywhere

Which is not what I want to do

[serene prawn]

Use whatever you're most comfortable with, i find bare functions hard to track/manage

[plush bloom]

hey anyone here?

[golden bone]

Nope

(don't ask to ask, just ask)

[plush bloom]

ok

i need help in registering my model onto the admin site in django

i think i did everything correctly

but the database is not popping in the admin site

@golden bone

[golden bone]

show your code

[plush bloom]

ye 1 sec

[plush bloom]

models.py

[plush bloom]

admin.py

is there anything else u need?

@golden bone

[golden bone]

Please stop pinging me, if someone can help they will

[plush bloom]

u asked to show the code...

and i thought u can help

srry

[golden bone]

I was encouraging you to ask your question... I don't know Django too well but it looks like your migration worked

[plush bloom]

yeaa

[golden bone]

I don't think models automatically show up in Django admin, you might need a Model admin class ?

admin.ModelAdmin

Yeah, check the docs,.I think that's what you're missing

[plush bloom]

ok thanks a lot man

[barren lava]

Hi, Nice to meet you

[plush bloom]

hello

[barren lava]

you solved your problem?

[plush bloom]

nope

can u tell wut is the problem using the photos of my code?

[barren lava]

yup,

no problem

[plush bloom]

r u really good with django?

[barren lava]

In order to see your user table on admin site , you need to register model

[plush bloom]

this is how u do it right

[plush bloom]

yep did that only

[barren lava]

and you can check your admin site.

[plush bloom]

yes i did

but it was not there

if u r open to join a vc or something i can screen share

[native tide]

I just want to make auto making thread / creating list. I just checked in console, the error says

[wild iron]

why am i getting this error, when even this error page clearly states that /register exists

[barren lava]

you need to add "register" in url.py

[wild iron]

already done that

i think the problem is with the keyword register, i just tried signup instead of register and it worked

noo

thats weird

coz i tried private window

and this works

but the normal window is putting a / in the end for some reason

so need to figure out why its doing that

[wild iron]

fixed it by creating another app for register

[carmine cipher]

Hello guy . Please someone can share with me a good roadmap to learn efficiently mobile app.I really need it.

[rotund perch]

@api_view(['GET','POST','PUT','DELETE'])
def testView(request, id=0, get_type='all', title=''):
  if request.method == 'POST':
    return Response("THIS IS GOING TO POST(CREATE)")
  if request.method == 'PUT':
    return Response(f"THIS IS GOING TO PUT(UPDATE) THE ID {id}")
  if request.method == 'DELETE':
    return Response(f"THIS IS GOING TO DELETE THE ID {id}")
  if(get_type == 'all'):
    return Response(f"THIS IS GOING TO GET ALL BECAUSE THE GET TYPE IS {get_type}")
  if(get_type == 'one'):
    return Response(f"THIS IS GOING TO GET ONE BECAUSE THE GET TYPE IS {get_type} WITH THE ID {id}")
  if(get_type == 'group'):
    return Response(f"THIS IS GOING TO GET A  GROUP BECAUSE THE GET TYPE IS {get_type} WITH THE {title}")
  
  return Response("none of the functions worked..")

is this a good practice?

Ive just put a response for earch not the thing I want to do but just for showing the code and to be more clear

[indigo kettle]

I prefer the class based views for this kind of thing

think about if you should be using elif. Even if the functionality will be the same, the logic is easier to follow if you use elif

[unkempt brook]

hello I am looking for help with this question I just posted in stack overflow - https://stackoverflow.com/questions/70792589/chromedriver-not-opening-django-development-server. Thanks in advance!

[short venture]

I agree. Function based views are mostly repetitive and unnecessary.

[serene prawn]

Function based views are fine, mashing multiple methods into single function is not 😦

[short venture]

That's the problem with the function based views. They get messy pretty fast. While it could've been done with CBVs much more elegantly.

[short venture]

You can use GenericViewSet in this case, as it seems.

https://www.django-rest-framework.org/api-guide/viewsets/#genericviewset

[rotund perch]

Okay thanks!

[short venture]

That's because of the APPEND_SLASH setting. You must add a slash at the end of the URL as a best practice.

https://docs.djangoproject.com/en/3.2/ref/settings/#append-slash

[serene prawn]

It could be better to use ViewSet in case you need custom logic and not just operating your models

[wild iron]

Oooh okay thanks

[rotund perch]

It inherits from what class

[serene prawn]

https://github.com/encode/django-rest-framework/blob/master/rest_framework/viewsets.py#L217

[lavish prism]

rest_framework/viewsets.py line 217

class GenericViewSet(ViewSetMixin, generics.GenericAPIView):```

[short venture]

Depends on the context but I didn't advise GenericViewSet because of the code block because that's for showing purposes, obviously. I advised GenericViewSet because he uses and wants to use multiple HTTP verbs, which is a perfect use case for it.

[serene prawn]

So why use GenericViewSet over ViewSet here?

[short venture]

Because he also implies CRUD operations, which can't be done without a model?

[serene prawn]

It depends

[short venture]

Generic one also provides most of the necessary logic for CRUD operations, which is a big plus, since he won't repeat himself.

[serene prawn]

Well, having CRUD already written for you is obviously nice but often you need custom logic anyways

[short venture]

You can still override those logic in the relevant methods. Still much easier with Generic one.

[serene prawn]

Don't think so Your requests might not map to your models 1:1

[short venture]

I don't think he's going to rewrite all the methods for the relevant HTTP verbs. That's not the case most of the time.

[short venture]

Can you be more specific?

[serene prawn]

Simple example using a Post model: when creating it you might want to link it to the user, perform custom validation, etc.
Having that logic in a serializer doesn't seem to be right imo

[short venture]

Why? That's the perfect use case for the serializers. Since validations are purely meant to serializers. In normal Django, we use forms for custom data validation and in DRF, we use serializers.

Also, serializer's create method is also perfect use case for it. Linking the user.

[serene prawn]

If you need to perform a validation based on database state (e.g. user can't have more than 10 posts) would you put that into a serializer? 🤨

[short venture]

Where would you put that, and why?

[serene prawn]

Into APIView/ViewSet method or a service function/class

[short venture]

Because?

[serene prawn]

Because this way my business logic does not reside in serializers

Also it's would be easier to test

[short venture]

Agree to disagree. 🙂

[serene prawn]

Imo having multiple responsibilities in a serializer is not really a good thing

It should validate incoming data, that's all imo

[short venture]

I don't think so. Think of forms (which is the exact representation of serializers in DRF). Forms do not only validate the incoming data. They mostly do all the necessary validation of the related models.

https://docs.djangoproject.com/en/3.2/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other

[serene prawn]

Tbh forms and serializers are different things, though, they're similar

Also serializers are generally hard to work with compared to say pydantic models

[short venture]

The official documentation doesn't agree with you.

https://www.django-rest-framework.org/api-guide/serializers/

You can see references of forms in that single article multiple times. To make it clear serializers are mostly the same of the forms.

[serene prawn]

Official does not mean i agree with it

Why would single entity have multiple responsibilities?

It's generally bad

[short venture]

This conversation isn't going to some meaningful and senseful point. So no need to keep it.

[serene prawn]

I really don't understand why you should perform anything beyond validation in serializers

[hexed crest]

does anyone know what text editor i should use

[unique shore]

VSCode is the most popular code editor

[scenic furnace]

any text editor can be used, so just use one that works for you

I use vs code, or if I'm working command line-only I'll use vim, but I've seen people use notepad++ and several others with no issue

[unique shore]

Sublime too

[serene prawn]

I think PyCharm and VSCode are most popular atm

[scenic furnace]

Ok so I have Flask-Session and Flask-SocketIO running together. Currently, when I run emit() inside a @socketio.on function the client that sent the signal that triggered the function is the only once to receive it. How can I emit() to all clients as well as to only the one client attached to a session?

Hello, I'm using Selenium to automate a purchase on a website. I'm not trying to automate captcha or anything, I just want to be able to input the captcha and then for it to move on.
Currently, I'm using ImplicitWait, but after completing the hCaptcha, it leaves me on the same page.

Any idea how I fix?

this is basically it

wait 40 seconds for captcha to finish, then continue however it doesn't allow that

it's just stuck on here

any help is appreciated :)

[golden bone]

Can you try to get whatever url you want after that?

You can also try waiting for the xpath instead of relying for the implicit wait

[lethal junco]

please help, can't run open-edx on pycharm

any idea? I want to run it localhost

Hey guys, I’m looking for a 0 to 1, beginner to advanced JavaScript book that is written for people who already know how to code. Any senior devs in here have a good recommendations ?

[lapis glade]

async def image_get(image_uuid):
    if image_uuid != None:
      image_link = "https://media.valorant-api.com/weaponskinlevels/" + image_uuid + "/displayicon.png"
      return RedirectResponse(image_link)```

How instead of returning a redirect can i get the image and relay that without a redirect

[lapis glade]

not a senior dev by any means but specifying what languages you coded in before may help others recommend

[inland oak]

Not really to advanced advanced level, as it is impossible to fit it into one book

But the best covering beginning stuff

[wide anchor]

I’m great at python, and I can get my way around JavaScript, Go, and Rust

But I’m not great at the last 3

[wide anchor]

Thank you again, I will check it out 💯

[scenic furnace]

Heads up for anyone testing multiple sessions in a Flask app and using Firefox to test: If you open multiple windows/tabs, they will share cookies and therefore share the session. Two Private windows are the same way. If you open a normal window and a private window, you can test up to two sessions at a time, but no more..

[wet meadow]

Could someone tell me some designs for my website?

[azure shard]

ah you see, I get the checkout link, and then I expect the human to do the captcha within the 40 seconds, then it will continue

the issue is that after completing captcha, it just stays there

[native tide]

That’s the way cookies in browsers are expected to work?

Multiple windows and tabs of the same browser will use the same session

[quasi summit]

Most probably wrong channel but has anyone written a Firefox add-on with Python or does know if it works and can point me to a tutorial or something?

Apparently it is not, need to do it in JavaScript

[warm lagoon]

if anyone has worked previously with selenium please take a look at my problem in #help_crossaint

[wild iron]

what could be causing this error in django

[serene prawn]

It should be request.POST, not request.post

python is case-sensitive

[wild iron]

ohh yeahh that was the error

thankss

[golden bone]

Right, so that's why I suggested that you tell Selenium to load the page you want after that.

Hello Guys,
I'm currently working with a python project that needs to integrate a SOAP based WebService
and i need to upload images with MTOM.
I've been searching for libs that i can use to deploy, but i'm not finding anything.
Does someone knows or have any official/alternative method that works in this case?

Hi guys, i'm trying to pass an url as a parameter with django for a view function, but i cant' manage to do it and i haven't been able to find anything online

If i try to use any other string it works as intended, but it's for an url shortener, so i need to pass links

[frank shoal]

maybe use a query parmameter?

{{base_url}}/add?url=https://www.google.com

Don't forget to urlencode it

[native tide]

i'm gonna look that up
