django will be helpful in situation like this if you want for be able to save before downloads of user to databse

for my opinion, nothing comes close to django admin interface. if u understand u see the beauty in easiness it makes :)

[golden bone]

I don't know what get_engine() is but it's expecting an argument

I think Table is used for a many-to-many relationship: https://docs.sqlalchemy.org/en/14/orm/basic_relationships.html

[crimson monolith]

Thanks! I'll check that link

[feral night]

I know, but idk why. Any tutorials or documentations has similiar codes and no error

[golden bone]

Share an example you are trying to follow?

[jaunty berry]

hello sir, can i ask somequestion about django4 in here ?

[chilly quest]

How do I share my data(specifically data stored in python objects) across multiple post routes in flask? Do I need a database and user-login feature kind of system to implement this? Or is it also possible to build this kind of feature for a guest user i.e. without keeping track of who the user is? I am currently using global class to store the data and share it across routes, but I think it works only for one user. It won't work if more than 1 people start using my web app coz data exchange might take place. How do I solve this?

[echo flicker]

Hi! I'm an intern react front end developer. I want to get started on back end development too. What should I do

Should I use python/django/flask or the typical node. Js?

[normal cipher]

depends. if you want to continue using js, go with node js or feathers js but if you want to use python and create backend easily with basic security then go with django

[echo flicker]

I do want to experiment with django...

[normal cipher]

if you are going to choose django, you won't be disappointed

[echo flicker]

Can you suggest some resources to learn and implement django?

[normal cipher]

traversy media's course is good. here's the link https://youtu.be/PtQiiknWUcI

I'm looking for recommendations on which framework to use for a simple app with one endpoint, which will be deployed in multiple VMs (worker machines). We are currently using Flask, and planning for some major refactoring, so just want to checkout other options. Any suggestions?

[patent sandal]

[wheat verge]

[normal cipher]

can you show me your base.html and home.html

[wraith pond]

does fetch api work in brave?

[golden bone]

A database is the normal way

[golden bone]

You'll need to do more troubleshooting or provide more information but I would guess you're not properly connecting to the correct database or not migrating your data/schemas correctly. Maybe try a help channel #❓｜how-to-get-help

[compact vapor]

NavigableString objects do not support the .contents attribute, as they can't contain anything. As Tag objects do, perhaps consider using isinstance to check the object type and only call .contents if the object evaluates to Tag.

[honest dock]

Yes because tr is of type Navigablestring and it doesn't have an attribute called contents

The first thing I notice is that the comments section takes at least a second or two to load. So you need to wait element_to_be_clickable or something like that. https://selenium-python.readthedocs.io/waits.html

django-channels question,
I have a ChatGroup model and when a Message is sent in a chat group how do I dispatch the event to all users who are in that chat group?.
Like the frontend will connect to a single endpoint like http://127.0.0.1:8000/api/ws and it'll receive an event when a message is sent in every chat group the user is in

[vague ember]

depends on if you are using a pull vs push approach.
In a pull approach, you may have to poll based on the latest timestamp. In a push approach, your servers would require the ability to push updates to the interested clients

That could become quite complex depending on the scale of the system

[digital thorn]

i need help can some one help me with this

does the table articles_authorarticles exist?

because the error complains it doesn't exist

hi guys , quick question, if i want to parse through every page with this tag:
from this baseurl:https://www.hltv.org/stats/matches?offset=0 could some one point in a general direction how to?

[slim skiff]

You can use beautifulsoup to parse the page in python, and you can increase the offset by 50 in every iteration to get new pages of data

[silent hatch]

yea im using BS to scrape, so it would be like, base url= the one i linked, and then parseable url would be 'https://www.hltv.org/stats/matches?' +str{offset} inside a loop? im kinda confused how would do it

ah fk sec i'll update that

[slim skiff]

yeah that seems reasonable, you just have a loop where you increment the offset by 50 in reach iteration

the offset is a query parameter, so you have to add it at the end of the url with ?offset=200

[silent hatch]

so like...

for offset in range(0,60000):
    .
    .
    .

im kinda confused with what to do inside

or would it be, offset+50

[slim skiff]

give me a second, I'll get to my pc and be more helpful 😀

Are there other services like Heroku where I can easily deploy a Flask app?

[golden bone]

Totally different use cases. For a public facing web app with any significant traffic, SQLite probably won't cut it. Mongo is NoSQl so it works pretty differently. If you want a SQL database that can scale up, Postgres would be my first choice but MySQL is fine if that's what you're used to

[golden bone]

Heroku is probably the best for small projects. PythonAnywhere is another option but I've not really used it. Then there's always the big three (AWS, Azure, Google)

[native tide]

@golden bone Thanks. I’ll stick with Heroku. I wish there was a free option that didn’t put the app to sleep after a period of inactivity.

[golden bone]

Yeah, the big three all have a free tier, but you'd probably have to pay after the trial period

[eternal blade]

oh thanks, how can I implement the push approach using django channels?

Because I will have to iterate through all connected users and check if they are in the chat group

Right now this is what I got ```py
@receiver(post_save, sender=Message)
def new_message(sender, instance, created, **kwargs):
channel_layer = get_channel_layer()

if created:
    chat_group = instance.channel.chat_group
    for member in chat_group.members:
        async_to_sync(channel_layer.send)(
            f"User-{member.user.id}",
            {
                "type": "chat_message_create",
                "payload": MessageSerializer(instance).data,
            },
        )``` and the data doesn't get dispatched throughout the websocket

Okay. Don’t really need a whole channel. Just a question about targeting. I need to target a part of a class since the class itself dictates the rating.

[cyan cobalt]

@gentle ingot That is the whole purpose for a channel. So they can give you further information about the situation.

[gentle ingot]

No I understand that. But like. I feel that’s a simple yes abs no and would feel bad for taking a channel from@someone lol.

Not going to lie, I have no knowledge about bs4; so I can't help you.

@gentle ingot Maybe you can ask someone else

Thats okay. thanks for the channel suggestions. heading there

[vague ember]

Assuming:

• You mean that you are using websockets between the client and server
• Different clients for the same group chat may be connected to different servers
• There is no concept of federation

You could either:

• have your server periodically check their DB/cache (ex: redis) for new messages for their connected clients
• listen on a kafka/pulsar/rabbitmq topic for update notifications. Note there could be additional measures to filter out unnecessarily traffic
• use a layer of indirection with some proxies where a group chat is "hosted" and all the clients part of that group chat connect to and then channel the updates through there. But it's more appropriate for real time use cases, and not something I would go into right off the bat due to the added complexity

I'm not that strong with Django but share the code where your dashboard endpoint is defined? Do you have other endpoints that are working?

[drifting radish]

where

problem is

there ```def main(request):
return HttpResponse(request, "main.html")

def dashboard(request):
return HttpResponse(request, "dashboard.html")

urlpatterns = [
path('admin/', admin.site.urls),
path('', include("Folder.urls")),
path('', dashboard),

]

urlpatterns += staticfiles_urlpatterns()```

[golden bone]

dashboard/ isn't part of your urlpatterns. I think it would need to be unless admin/ is the endpoint you're really looking for

but

What kind of work do python backed junior Django

[warm dagger]

so I am making my first website using django. It's going good but I am having this overflow issue.
Basically a long 'word' overflows out of the div. I searched on internet and used stuff like overflow-wrap, break-word but they don't seem to work.
Any help is appreciated.

here is the html just in case.

{% extends "blog/base.html" %}
{% block content %}
<div class="content-section">
  <div class="media">
    <img class="rounded-circle account-img" src="{{ user.profile.image.url }}">
    <div class="media-body">
      <h2 class="account-heading">{{ user.username }}</h2>
      <p class="text-secondary">{{ user.profile.bio }}</p>
    </div>
  </div>
</div>

More nitpicky stuff, but on mobile, I would probably center the icons and perhaps use a black background behind the "we aren't vpn" + icon div for some more contrast.

Hello, could anyone here help with an error I'm getting in Django?

I'm saving some rather long reddit comments to my psql database. They're stored in a TextField with a unique = True constraint
(I'm relatively inexperienced and I didn't want to accidentally add duplicate values to my database).

Trouble is, Django is now throwing this error when I run:

index row size 2808 exceeds btree version 4 maximum 2704 for index "saved_posts_toplevelcomment_contents_key" DETAIL: Index row references tuple (2,28) in relation "saved_posts_toplevelcomment". HINT: Values larger than 1/3 of a buffer page cannot be indexed. Consider a function index of an MD5 hash of the value, or use full text indexing.

I've had a look online and it seems that psql adds an index for the unique = True constraint that I've added.
I'm not sure how to solve. I just want to make sure there are no duplicate values. Should I add some logic in my view to this effect and just remove the unique constraint?

[silent hatch]

maybe someone could help me around, how can I concatenate the data I parsed using scraping functions into a DF?

Hello, I have a machine learning model which I converted as a Rest API using Django rest framework. Now I want to distribute the API to users but how can I authenticate and limit the requests by the users by allowing them to interact the api using an api key?.

[dense slate]

I would think that the user would need an account that is associated with the API key to start off with.

So each user has a unique API key.

Then you could just control everything with user authentication as usual (whatever backend web framework you use).

I'm not sure the best way to throttle though, as you would need a way to keep the current usage somewhere. If it's just how many times per day, perhaps you could just have a field on their user account that counts how many times they access, and reset it at a certain time of day or after a number of hours.

[sacred crane]

Thanks @dense slate How can i give every user a new api key when they register with a new account in Django rest framework?

Did you mean using JWT?

[dense slate]

You could generate a new key on signup. I'm not sure what you're asking beyond that.

[sacred crane]

Thanks

[south arch]

Hello, can anyone explain me one thing about Django?

My problem is that in production (I am using App Engine(Google Cloud)) my templates load old staticfiles.

I am wondering why this happens.

settings.py
STATICFILES_DIRS tells me where to search for static files that are not tied up to a specific app.

STATIC_ROOT is the path where we store the static files of every app once we run python manage.py collectstatic

STATIC_URL is just a prefix for static files.

Why in localhost it shows me the updated files and why it doesn't happen the same in production?

[dense slate]

Running with gunicorn? Is that a thing in your production environment?

I wonder if you have a cached version showing.

[south arch]

I am not

I am right now checking

it doesn't even work in localhost now if I use the remote database connection

it just shows me a file that I don't have in my Django project folder

that file has been edited

but I see the older version

it's like when I render the template, it takes the files to another place

[dense slate]

You sure you edited the correct file?

[south arch]

yes I did

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR,  'staticfiles')
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'website/static'),
)

it means that when the template render, it looks for files in /staticfiles once I run python manage.py collectstatic

the file I made changes to is correct in /staticfiles

but it's not the same that I see using Development Tools when the website runs

/staticfiles/stuff.css

Development Tool

the structure also looks clean

there's no way

I am wondering.. is it possible that it search for the files in Google Cloud Storage?

But there's not a bucket that contains those files, so, where is it taking them from?

I am completely sure that it doesn't look for the new files when I upload the website, because, as I said, both website/static/website/stuff.css and staticfiles/website/stuff.css are correct

that's just like it takes them from another place, but the url in HTML it's correct as well, is just the file that's different

[dense slate]

What's it showing incorrectly? The CSS or the template itself?

[south arch]

every static file that I edit

css, js, html

it just stopped working

I have been using a Google Cloud instance that I replaced by a new one

but instances doesn't get involved with buckets

[dense slate]

are your dirs correct? shouldn't there be / at the end?

[south arch]

everything's correct

it worked until yesterday

without reasons, it started doing this

@dense slate is it Gunicorn the tool that creates staticfiles.json file that contains all the staticfiles paths?

or is it WhiteNoise?

[silent hatch]

nothing happend3s without a reason

[dense slate]

Gunicorn uses workers to serve your pages to visitors.

But you need to restart it when you change files.

Probably not the case if you didn't set it up yourself.

[south arch]

I think that there's a problem with myself then

when I do
{% load static %}
and use
{% static 'website/stuff.css' %}

[south arch]

is it looking in "staticfiles/website/stuff.css" or in "website/static/website/stuff.css"?

do I have to store the statifiles in another place in production? Can't I just do like I am doing?

I mean, if Djagno uploads the files to "staticfiles" folder, why do I have to upload then to another place?

I also added the right settings in urls.py

[dense slate]

you can print the base_dir locally and look at your terminal to see what the directory should be/is

that way you can rule out if it's a directory issue

You put files in static, and collectstatic puts them somewhere else on its own.

You don't put them in two places manually.

[south arch]

yeah but I did check that the files are correct

I do have an idea

[south arch]

I want to check what's this output in production

it could give me some informations

[dense slate]

ah ok

[south arch]

just give me some time to check for google cloud log's output

let's see

the output looks clean

i just tried to delete all index.html content 😂😂

the page just shows!

that doesn't even make sense

I am running in local, in local database

that's up to Django

that doesn't make sense

I FOUND THE PROBLEM

Using DEBUG = True saves the changes, using it to False does not

I am sorry but I just don't get it

how is it possible that the error is related to that?

I just saw that static files are managed by the web server when Debug is set to False, why that? I mean all the files are in /staticfiles, why get them from the server, and maybe, perform a longer task to get them?

Hi guys i need one help
how to check the duplicate record in all the fields like (name,email,id)
in django

[inland oak]

how about enforcing Unique property

it will prevent creating records in database that aren't unique

[serene prawn]

@inland oak Btw i think django way of duplicating record is setting id to None and saving it? 😅

[warm dagger]

(used django) This is thr class in forms.py

class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()
    username = forms.CharField(max_length=30)


    class Meta:
        model = User
        fields = ['username','email']

what should I do to not update? (before this username was fixed to max 150 characters by defaut)
before I added that username variable (basically trying to chnage the max length from 150 to 30) by defualt the username with spaces (or anyhting beside letters, numbers and those characters) will not be updated but here it does.

or to be more exact I need a way to change the max length of the username without changing other stuffs that are in default

[serene prawn]

What's the problem here?

You have whitespaces in your username, they probably are not permitted by default

[inland oak]

huh? You can forbid Blank values too

[serene prawn]

I meant that it's the way to duplicate record essentially 🤔

e.g.

item = Item.objects.get(pk=1)
item.id = None
item.save()

[warm dagger]

before I added that username variable (basically trying to chnage the max length from 150 to 30) by defualt the username with spaces (or anyhting beside letters, numbers and those characters) will not be updated but here it does.

wireguard is VPN protocol
VMware is virtualization technology / + company that went as another cloud provider I think

they aren't alternatives to each other, they are different types of technologies

[stark tartan]

Ohh

I think Cisco merkic also there

[inland oak]

i mean, you could use wireguard at different cloud providers (as well as my application can be applied to different providers)

but I get confused with your questions

Did you from django.contrib.staticfiles.urls import staticfiles_urlpatterns and urlpatterns += staticfiles_urlpatterns() in the urls.py

[crimson monolith]

Hello. In Flask, when using the Application Factory pattern together with Blueprints, why does initializing flask-restful differ from other extensions like flask-sqlalchemy? I initialize my database in the create_app function, but the api is initialized in the blueprint itself:

api_bp = Blueprint("api", __name__)
api = Api(api_bp)

#Add resources to api
api.add_resource(HelloWorld, "/")

And then I just register the blueprint in create_app() and that's it. Trying to do it like you do with a database (db.init_app(app)) doesn't work, but doing it from the blueprint directly does work.

is the api only way to connect django and react?

[serene prawn]

Basically yes

[thin dome]

oh ok

[serene prawn]

api stands for "application programming interface", basically an interface through which different programs could interact

REST is popular choice for building web api's

[thin dome]

can we use fastapi?

[serene prawn]

You'd need something similar to interact with your django from react app

You can, but you don't **have ** to

You can build rest api's with django too, though i like fastapi more it's harder to setup

[thin dome]

wait

we can setup fastapi in django?

[serene prawn]

You can but it's kind of a mess 😅

[thin dome]

which ones easier rest or fastapi?

i think fastapi

Fastapi is a framework, rest is style of your api architecture

You can use rest with fastapi

Well, you can use them together but grahql isn't rest

Your api can provide multiple endpoints over http, say
/users for some rest operations
/graphql for graphql queries

Yep, but REST doesn't specify a schema format, usually that's done via OpenAPI schema that would describe all your endpoints, their inputs and outputs

@sand oracle
Many libraries are still actively developed and don't have solutions for things like authentication, permissions, validation, etc

On the other hand REST is quite mature

Plus if you migrate from REST to GraphQL you still might need or want to keep the old api

github and gitlab use graphql for some of their services

Not sure about github but i think gitlab uses graphql a lot

Also if your api is used by other developers it's often easier to use REST for them than GraphQL

[inland oak]

Lets clarify, MongoDB for NoSQL Document Type DB

there are multiple times of NoSQL types databases, and each one fits its own niche / usage case

[golden bone]

I feel like I see MongoDB used with Django a lot, but I suppose the other types would work fine too?

[inland oak]

definitely. NoSQL Key Value type database Redis/RabbitMQ is quite often used in pair with Django

Hey ! searching for someone that knows about Google Analytics reporting API :
I'm having an issue with my responses containing several pages when i'm querying segments
The page token stays the same, and if i remove the segments without changing anything else from the report request, it works as expected
Do you know what happens ?

Hi, I just released some of the code I use in running cron jobs in the form of a django package.

I would really appreciate if you took a look, maybe made some contributions or share some feedback.

A GitHub star would also be great. Thanks!

https://github.com/paulonteri/django-serverless-cron

django-serverless-cron is a Django app with a simpler approach running cron jobs.
This is done through exposing a HTTP endpoint to invoke the jobs that allows you to run any task without having to manage always-on infrastructure.

There is also an option to run jobs via management commands and the Django admin.

Why?
----

This is essentially a replacement/supplement for a traditional OS 'cron' or 'job scheduler' system:

- Serverless cron jobs no-longer a pain.
- Schedule jobs to run at a frequency that is less than 1 min. (crontab is limited to 1 min)
- The machine running crontab is no longer a single point of failure.
- The problem with the above systems is that they are often configured at the operating system level, which means their configuration is probably not easily 'portable' and 'debug-able' (if you are developing on Windows, the scheduler works differently from Linux or Unix). Also can not easily be integrated into a development environment.
- Manually triggered cron jobs. Eg: via the Django Admin.
- Alternative to cron services that aren't always available on free (and sometimes paid) web hosting services.
- Easier access to cron job execution logs and monitoring execution failures.
- No need to learn crontab. Think of it as a friendlier alternative to traditional cron jobs. Simple cron job creation. No need for cron syntax, no guessing on job frequency. Easy controls.

this is my way on replacing and rendering HTML using Flask:

    lines = [line for line in file.readlines()]
    new_lines = []
    for line in lines:
      if str1 in line:
        line = line.replace(str1, str2)
        new_lines.append(line)
      else:
         new_lines.append(line)
  file.close()
  return "".join(new_lines)

app = Flask(__name__)

@app.route('/')
def page():
  file = "index.html" # or whatever the name of the HTML file you are rendering
  return render(file, "{ test }", "Hello World!")

if __name__ == '__main__':
  app.run('0.0.0.0')

index.html:

<!DOCTYPE html>
<html>
  <head>
    <title>Python Rendering test</title>

Well, that error is just saying that the endpoint you're trying to reach doesn't exist - maybe it was written incorrectly in the urls.py.

I'm sure simplejwt has a method to setting up an endpoint and accessing it.

[jaunty magnet]

can my vue/react frontend grab data from a django backend WITHOUT creating a restful api with django rest framework? I've only have only learned by creating an api, but im curious why it has to be restful, cant I just grab it from the regular django urls.py ? Need help understanding that

[golden bone]

REST is considered good practice but not required

[finite root]

it seems like you are not using your context variable

[jaunty magnet]

so could i technically use a react app with regular django instead of using their templating language? How would you fetch the data if its not over HTTP?

[golden bone]

I'm sorry, I thought you just wanted to make your API non-REST. I'm not sure what "regular Django" would mean or how that would work without the API

[dense slate]

You can follow GraphQL instead of REST?

But you need some kind of API for sure.

You can grab data without following either, with something like an ajax call.

[vague ember]

(also grpc, thrift)

[dense slate]

I think it helps to follow a REST or GQL setup if you expect to grow in complexity.

im getting an error

[visual cedar]

best practices question:

When I want to save a base URL, for example 192.168.100.50/api

And there are endpoints like /api/people, /api/houses etc

is it better to have the root include the slash at the end or should I add in the slash on every axios call myself?

tldr is:

is this preferred 192.168.100.50/api or is this preferred? 192.168.100.50/api/
when being stored as a variable to be appended to endpoints?

I know this is an incredibly lame thing to ponder about lol

[agile pier]

how to use that? pls tell the syntax..

[wooden ruin]

why not have both work? django's CommonMiddleware automatically appends the / to the end of the url so visiting /api/people and /api/people/ works the same

[ocean slate]

Hello everyone, I want to make a project website in Flask in which there is a price comparison among products . The price is compared with different e commerce websites like Amazon and flipkart ( just as an example here). For example if a person comes on my site and in the search bar he searches about Samsung mobile Model - Galaxy j7, so when he clicks on the compare button, my site would show prices of that specific product from all different e commerce website( or which I have agreed to ).

How is this possible? API ? or anything else

I hope, I am able to tell you the exact problem.

[stark tartan]

Means you want Galaxy j7 right ?

[stark tartan]

Actually you can do this my web strapping or you may get API from Amazon or fipkart

[stark tartan]

A prefer a /api/ and in axios I sent in that format but in react router in use without back slash

clarify the way you launch the Flask server

where do you press "Run" server button, or where you insert CLI command to launch it, and what is the command

[hard whale]

I just run the app.py in pycharm

tried to run is from CMD: python app.py as well

same result

[inland oak]

What is your flask version

[hard whale]

I don't know, installed it yesterday via pip

[inland oak]

Run 'pip freeze' to see the version

[hard whale]

Flask==2.0.2

click==8.0.3
colorama==0.4.4
Flask==2.0.2
itsdangerous==2.0.1
Jinja2==3.0.3
MarkupSafe==2.0.1

[inland oak]

Do u have WSL?

Or docker desktop

[hard whale]

both

not 100% sure if installed them correctly

but yes i installed them

[inland oak]

That simplifies stuff

I ll just write dockerfile for your server

Try to run with it

We will see if smth changed

[hard whale]

Thank you, I was thinking of it as well

[inland oak]

As alternative

[inland oak]

Try for now the other way...

[inland oak]

export FLASK_APP=hello
flask run

Export or Set

Hello name of your flask file

Run server with flask run

flask run --host=0.0.0.0

[hard whale]

• Serving Flask app 'hello' (lazy loading)
• Environment: production
  WARNING: This is a development server. Do not use it in a production deployment.
  Use a production WSGI server instead.
• Debug mode: off
  Usage: flask run [OPTIONS]

Error: Could not import 'hello'.

ah ok

[inland oak]

export FLASK_APP=app

[hard whale]

should both flask app and index.html be in same template folder?

[inland oak]

No

Index.html should be in folder templates

[hard whale]

flask run --host=0.0.0.0 is safe operation?

won't it expose anything to outside my pc?

i have sensitive data n my pc

[inland oak]

It will to your local network.
It will expose only web site
Your local network is highly likely unseen to public anyway

You don't have static IP, right?

[hard whale]

no, IP is dynamic

[inland oak]

It can be checked by writing ipconfig and comparing shown IP with https://httpbin.org/ip

If they match, u have static public
If not, u not, u don't have public static

Anyway, run and check already

Without 0.0.0.0 if u wish

It should not be important

[hard whale]

I have an idea, i'll use flask server on rpi anyway so i'll run flask server on rpi and try again

afaik pycharm might somehow screw up flask server if you are not pro

rpi has less stuff that can go wrong

[inland oak]

That is why u should run it from CMD
Preferably from venv CMD

[hard whale]

i tried both venv and outside venv

[inland oak]

Also there is always an option to start using virtual machines of Linux

[hard whale]

outcome is same

[inland oak]

I ll try to run your stuff

[hard whale]

as long as the whole project will use RPis i'll just switch the flask dev part there, just need to setup headless mode first

I dont even know how venv works in detail

[inland oak]

well, i have everything working smoothly. Lets try docker solution then

[inland oak]

How much time required to learn that docker

[agile pier]

?

[normal cipher]

yes

[golden bone]

It's one of these things where you can go deep and learn a lot for a long time, but the basics you really really need don't take long. It's well worth it if you have any need at all

If you browser the docs a bit you should be able to understand what that YAML does... It's basically just using an alpine Linux image to set up a container (a little bit like a virtual machine if you've ever used VirtualBox or whatever) and then it does some basic configuration like setting environment variables and copying files into the container

[agile pier]

Hello everyone, I need help for a django project. I created a model called "Order", and I need to create a filter system. So I created a form method="GET" with all the filters I need. But when I choose multiple values for a field (for example called "marketplace"), it's creating my url like :

?marketplace=firstvalue&marketplace=secondvalue

In the views.py, request.GET.get('marketplace') is giving me "secondvalue" only. Is there a way, without using javascript, to get multiple values for one field ?

Or is there a better way to create a filter system ? 😄

[lilac solar]

To answer this directly - the GET object is a special dict from Django that has a getlist function (Docs here: https://docs.djangoproject.com/en/4.0/ref/request-response/#django.http.QueryDict.getlist)
More broadly have a look at https://django-filter.readthedocs.io/en/stable/ which is probably going to be a more robust solution.

i dont want to query here

I want to query in another function

[inland oak]

Okay

[inland oak]

Your info thing can be simplified too.

U a reading from database and then updating. U a doing two actions

While u can do just one, updating the necessary thing

Also counting in such way in not transactional queries I think Is asking for troubles

Better to rewrite to transactional
Or if to keep it simple, to change the counting into another way (like quering table of substractional records)

@agile pier boop

[agile pier]

how can I simplify the info.availability part?

[inland oak]

Read Django orm syntax that contains

Object.update() method

okay

[valid vale]

you need to first add the template folders name in settings

did u add that?

[livid pike]

Yes, right here py TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [r'templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ]

[valid vale]

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR / 'templates']
        ,
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

so if you are using django 4.0 then try this .

define tamplate path like this as django doc mentioned

I guess your watching an old version Tut of django

[livid pike]

I'm using 4.0.2, I'm getting the same error even after adding BASE_DIR:

Scraping one file and scraping a thousand isn't too different, but yes you need to do it "one by one". Just use a basic for loop

[silent hatch]

so theres no way to build a function that could run through the whole directory and scrape all the files together into a DF?

[golden bone]

Yes, you can do that with a simple for loop

results = []
for filename in filelist:
     page_result = scrape_my_file(filename)
    results.append(page_result)

I leave it to you to write your scrape_my_file function but that's the idea

    return {'result': response}
``` I was unable to pass solute and solvent in `    results =  background_tasks.add_task(predictions(solute,solvent))
` but i am getting they are not defined.

Can I access local/session storage variables using flask? Please ping me when you reply

[unkempt wave]

how do I insert a clickable link into code

[latent cosmos]

Greetings, what technology would you use for simple website (busniess-card like). Website doesn't need database. I used to went with python Flask/Djagno/FastAPI but what to choose if it doesnt need database? I do not know JS as well.

no wordpress please, too slow

and I appreciate if you could ping me while answering, thank you

[golden bone]

I personally like Hugo a lot. Pick a template, tweak it as needed, and generate your site.

You could also just build the site directly with traditional HTML and CSS. Bootstrap is probably worth looking at if you want to do that

Hi guys

I

I'm not too familiar with web dev and python, but I'm trying to create a login system where a large group of people can login to the website and redeem their points

Currently, I've been thinking of using Postgresql as the database, python as backend, and the frontend well whatever the front-end dev wants to use (which is not me)

For the backend, would flask suffice?

[vague ember]

I believe it would for the most part

[native tide]

So I wouldn't need something like fastapi correct?

I was told that I needed an api to interact between postgresql and the front end, so in this case

would flask take care of that?

[normal cipher]

I'm not an expert on backend but I think you should try django

[native tide]

I was thinking about django, but I heard it has a steeper learning curve than flask, and right now, I'm trying to finish the website by june so that's why I been thinking of using flask

[native tide]

@normal cipher btw can u answer this question?

[normal cipher]

you can easily learn django in a month including rest framework if you already know python

[vague ember]

there are extensions for db access.
But tbh, for the nitty gritty details of flask vs fastapi, I wouldn't be the best person

[native tide]

Why do you recommend django over flask? It's more powerful or something?

[normal cipher]

no, you won't need fast api if you are using django

[native tide]

okay so really I just need django, postgresql, front-end?

[normal cipher]

django is alot better than flask. it provides a MTV and normal security + django is better with urls and modules

[native tide]

This is going to be my most "complex" project up to date, so please bear with my questions lol

[normal cipher]

sure, ask me anything anytime

[native tide]

Okay sounds good. Do you have any recommendations to get started in django?

Also, I'll be SSH into a raspberry-pi (the server) which is going to hold the database, does that influence anything?

[normal cipher]

if you like reading, I would say read docs but you can watch Traversy media course of django

[native tide]

oh yeah reading is faster, thanks. Mind if I dm you if I have questions?

[normal cipher]

sure, why not

[native tide]

alright thanks for your help today

class VaccineCenterDetails(models.Model):
    Center_Id = models.IntegerField(primary_key = True)
    pin_code = models.IntegerField()
    VaccineCenterName = models.CharField(max_length = 255)
    address = models.CharField(max_length = 255)

    def __str__(self):
        return self.VaccineCenterName

class VaccineDetails(models.Model):
    Vaccine_ID = models.IntegerField(primary_key = True)
    Center = models.ForeignKey(VaccineCenterDetails, on_delete = models.CASCADE)
    type_of_vaccine = models.CharField(max_length = 255)
    availability = models.IntegerField()
 
    def __str__(self):
            return self.type_of_vaccine

How do I filter on the basis of foreign key field ?

def search(request):
    pincode = request.POST['pincode']
    context = {'vaccineDet':VaccineDetails.objects.filter(VaccineCenterDetails__pin_code__contains = pincode)}
    return render(request, 'display.html', context)

I tried using __ but i m a little confused

[inland oak]

Since they recommend Django
https://www.django-rest-framework.org/
Then u could probably have a look at this to add

For your situation, Django augmented with DRF should be nicer

[native tide]

What's the purpose? Sorry I'm hella confused

Is it like an add-on to django?

[inland oak]

It is out of the box solution to make API out of Django, prepared to serve as just backend to different front

[agile pier]

solved
it was Center__pin_code = pincode

[inland oak]

Yes

[native tide]

Okay so django is the framework for the backend, then I just use django-rest-framework as the api?

[inland oak]

Basically it is bunch of already prepared solutions for all your problems to make Rest API

[native tide]

What are the different types of APIs I can use? Only Rest right?

[inland oak]

Your sentence is not making sense to me

[inland oak]

There are different options, REST API is the dumbest easiest one. It should be all u need

[native tide]

For the backend, I use the django framework right? And the whatever u just linked will act as the REST API?

[inland oak]

I linked you Django Rest Framework, it will serve to be used as Django backend framework to make a REST API

[glacial portal]

How would I protect one of my routes?

Like if a certain role can access the route

[inland oak]

Seeing no details, which framework or any code the person wishes to protect, darkwind gave sensible advice:
Take pepper spray for protection with you!

Anyway.. if it is Django, you need just to extract current user for the request

Check his role

And return error for all who don't match your criteria

Feel free to wrap into decorator, for reusage at other routes

Technically same thing in any other Frameworks.
Difference only in different way to acquire Auth state, which depends on which Auth system u used

[glacial portal]

I see thanks!

I would have to learn decorators tho

Btw the comedy was appreciated

how do i reply to a GET /favicon.ico HTTP/1.1GET / I tried to respond it with this

HTTP/1.1 200 OK

Content-Type: text/html

<!DOCTYPE html>
    <html lang="en"><head></head>
    <body><img src="htdocs/favicon.ico"></body></html>

but it doesn't seem to be working, I have the favicon.ico image in htdocs folder

i am building a webserver with socket module

[inland oak]

Darkwind looked at the random rendered html code of an unknown code and unknown framework

And questioned:

[wraith pond]

uhm?

[inland oak]

you have to be providing a bit more details about your situation

if you wish other people to help you

[wraith pond]

how do i respond to a http request that says GET /favicon.ico HTTP/1.1GET /

i am building a webserver from socket

not using any framework like django or flask

[inland oak]

code examples are welcome

[wraith pond]

examples?

i just want to know the basic reply to GET /favicon.ico HTTP/1.1GET / when you have the image

[inland oak]

okay, I guess it is clear enough now

[wraith pond]

other wise i would just respond with HTTP/1.1 404 <CRLF><CRLF>

when the user didn't has the image

but now i have the image and i want to respond with the image

[inland oak]

view-source:https://flask.palletsprojects.com/en/2.0.x/tutorial/static/
i am checking source code view for <link rel="shortcut icon" href="../../_static/flask-icon.png"/>

it renders this code if opened in a separate page this url

https://flask.palletsprojects.com/en/2.0.x/_static/flask-icon.png

<html style="height: 100%;"><head><meta name="viewport" content="width=device-width, minimum-scale=0.1"><title>flask-icon.png (180×161)</title></head><body style="margin: 0px; background: #0e0e0e; height: 100%"><img style="-webkit-user-select: none;margin: auto;background-color: hsl(0, 0%, 90%);transition: background-color 300ms;" src="https://flask.palletsprojects.com/en/2.0.x/_static/flask-icon.png"></body></html>

[wraith pond]

i did reply the same

just didn't include the css

[inland oak]

hmm. perhaps somehow directly file can be sent in the request

files can be attached to request

[wraith pond]

yes?

[inland oak]

as the only idea I have...

...you could try to enable thing like Wireshark

raise dummy http server wtihout ssl

and to request from your browser the favicon.ico object

you should be able in Wireshark to sniff exactly how the answer is looking like

[wraith pond]

wait so i respond to a request with my own request?

[inland oak]

Or perhaps favicon just can't be transmitted in the web socket protocol?
I am a bit unsure how you try to transmit it

[wraith pond]

you know socket module?

[inland oak]

We can send an image as encoded into base64

[wraith pond]

yes i read about that how to do that

[inland oak]

nah, never dealt with socket beyond seeing the code of a simple web chat

and coding a chat with sockets in the past 🤔

in C++

[wraith pond]

nice

story

[inland oak]

Where are you responding at all?

provide code example actually 😉

so far you look like trying to imitate web server to me

are you trying to reinvent the nginx?

[wraith pond]

client_connection, client_address = server_socket.accept()
...
      client_connection.sendall(response.encode())
client_connection.close()

[wraith pond]

response is this thingy

[wraith pond]

definition of server_socket

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((SERVER_HOST, SERVER_PORT))
server_socket.listen(1)

[wraith pond]

[inland oak]

http://www.columbia.edu/~fdc/sample.html
lets see, if we enable this testing web site without encryption

We can see favicon sent with 200 code in type x-icon thing!

[wraith pond]

yess

how do i even send it in x-icon

i tried reading the favicon.ico with "rb" and truncated it to response

but it didnt display

[inland oak]

Oh look, detailed about request of favicon

Content-Type image/x-icon

remember we were setting in python Content-Type application/json when sending json answers? looks the same

[wraith pond]

i was setting text/html when sending my stuff

[glacial portal]

@inland oak or else

[inland oak]

xD, never dealt with it before, but looks like fun

[wraith pond]

where did it send the favicon.cico i cant see it

do i need to like gzip it

because i tried that too

[inland oak]

not sure, Content-Length: 5430 i can see only this a trace of icon for now

[wraith pond]

let me try this but adding the content of favicon.ico to this

[inland oak]

I think you don't need gzip

it is just browser sends request, that it CAN accept in gzip

but it should NOT HAVE to be response with gzip

[wraith pond]

yea i figured it out when it didnt work

it can accept encodings like br and deflate too

[inland oak]

Found another Clue!

[wraith pond]

bytes?

[lavish prism]

Hey @inland oak!

It looks like you tried to attach file type(s) that we do not allow (.har). 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.

Check detailed info about response

"text" field has the data of the icon

[wraith pond]

yessss

[inland oak]

xD, even having no idea about the thing, I found it. yay.

[wraith pond]

okay but what now?

the data i read from ico file is \x00\x011

is like that

[inland oak]

obviously it is base64 encoded

yeah, it is even told there

encoded: base64 in the json

[wraith pond]

ok now the problem

is

nvm wait

[inland oak]

Just for the future debugging purposes, the json was received in Network chrome tab
when Ctrl+F5 resources and right clicking to save all as HAR at http://www.columbia.edu/~fdc/sample.html

[wraith pond]

still not working

here is what i have

        with open(f"htdocs/favicon.ico", "rb") as f:
            response += f"Content-Length: {len(f.read())}\n\nContent-Type: image/x-icon\n\n"
            response = response.encode() + f.read()
            print(response)
            client_connection.sendall(response)

[inland oak]

https://docs.python.org/3/library/socket.html

is that what you are using?

which python version?

[wraith pond]

prints this

b'HTTP/1.1 200 OK\n\nContent-Length: 1150\n\nContent-Type: image/x-icon\n\n'

not working but possible a hint for clues

he sends favicon too

[wraith pond]

woah still unanswered

probably because the title is bad

need to be named respond to Get request for favicon using local web server via sockets

or something like that

[inland oak]

this was given from professor

so it should be in theory half working already

just few things to fix

[wraith pond]

hmm he re-econded it to utf-8

the favicon file

the https://www.rfc-editor.org/rfc/rfc1341#page-51 it says too less

https://www.rfc-editor.org/rfc/rfc1521#section-5.2

[inland oak]

https://github.com/danginsburg/Fos/blob/master/very_scratch/server/example6/python-socket-server.py

highly likely it is python2

[wraith pond]

i kinda did literally the same

elif data[0:25] == "GET /favicon.ico HTTP/1.1":
        print "favicon"
        contents = open("favicon.png", "rb").read()
        socko.send("HTTP/1.1 200 OK\r\n" 
        "Connection: close\r\n" +
        "Content-Type: image/png\r\n" +
        "Content-Length: " + str(len(contents)) + "\r\n\r\n" +
        contents)

except i dont know about the \r

[wraith pond]

it is png?

i have the file as favicon.ico

[inland oak]

favicon can be sent as png

I encountered such examples

[wraith pond]

yea ik

it can also be sent in jpg

shall i try using a png?

but the colombian site sent a ico

[wraith pond]

i literally hate rfc it is so hard to navigate

[wraith pond]

let me try adding \r

[inland oak]

Text files created on DOS/Windows machines have different line endings than files created on Unix/Linux. DOS uses carriage return and line feed ("\r\n") as a line ending, which Unix uses just line feed ("\n").

i think it is just a windows thing

[wraith pond]

ah i am not windows

so the only thing that differes is the png

and the encoding

        with open(f"htdocs/favicon.icon", "rb") as f:
            response += f"Content-Length: {len(f.read())}\r\nContent-Type: image/x-icon\r\n\r\n"
            response += f.read()
            client_connection.sendall(response.endcode())

as expected it throws a error when not encoding the response

before __iadd__ to f.read()

[unique nova]

hey guys, anyone willing to help regarding objects.annotation in class based view?

            response += f"Content-Length: {len(data)}\nContent-Type: image/x-icon\n\n"
            response = response.encode() + data
            print(response)

but seriously it is still not working

[inland oak]

well, duh

[wraith pond]

duh?

[inland oak]

data = f.read() is a byte array

response += f"Content-Length: {len(data)}\nContent-Type: image/x-icon\n\n"

you add byte info to regular text info

[wraith pond]

no

you see i encode

it before adding

[inland oak]

i see you encoded response.encode()
