Hello
How is it possible to implement HSTS in Flask, please?

[ornate flame]

So make it?.........

[ornate flame]

Take a look at this maybe: https://github.com/GoogleCloudPlatform/flask-talisman

[timber jungle]

Just this or there is more? 🙂

from flask import Flask
from flask_talisman import Talisman

app = Flask(__name__)
Talisman(app)

[vapid sapphire]

Sir but I don't know how to do it

[ornate flame]

The default configuration:
Forces all connects to https, unless running with debug enabled.

Enables HTTP Strict Transport Security.

It says it does

[ornate flame]

Maybe list the features you want to make here

[ornate flame]

This is a good tutorial

[timber jungle]

thank you, i will try to destroy my app 😄

[vapid sapphire]

thank you sir I will have a look

[ornate flame]

what is that supposed to mean? I don't humour sometimes 😂 😅

[ornate flame]

No worries, and please don't call me sir 😅

[timber jungle]

It is easy to create a web app, but the same web app should also work after implementing some security features 😄

[vapid sapphire]

Sir in my fitness app there should be steps counter, calories counter, workout plans or a app like healthyfime

[ornate flame]

You want to make an app or website?

[hollow dragon]

Guys, do you have any recommendation to add to my first Flask project? https://hwizlh.herokuapp.com/

[timber jungle]

Make a check if the email has an @example.com
dont let the user enter fooba.example.com

make the check in backend

[hollow dragon]

Alright

[timber jungle]

You can implement this check in HTML as well. With this you can check before the user presses Submit
but everyone will be able to modify the HTML and bypass it.

This is why you should also make the check in back end as well.

[hollow dragon]

Yeah, I know about that, I'm also using password_hash, but since it's just a project for an internship I'm not really concerned about issues like that.

No one will use this but yeah, I'll look into that, thank you mate!

[vapid sapphire]

A website

[timber jungle]

even if it is internal, there will always be at least one person with malicious intents, just for the lulz.
if it is internal, it is better, because you can force users to enter only one type of email address.

This is my check, it only allows [e-mail]

import re
        googleemail = re.compile(
            r"(\.|^)[\w]{0,64}(\w+[\.]\w+){0,54}@(google)\.com(\W|$)"
        )

[hollow dragon]

Thank you mate for the help

On the other hand, what do you think about the project? I know its not extra complex but im coming from frontend and I've learned a ton about flask and python making this.

[timber jungle]

I am not the right person to go into more details about it. I am new to flask myself.
from my pov, the mail seemed like an important subject . 🙂

[hollow dragon]

Ah sure, I really like flask tho, it's pretty good.

[timber jungle]

I sometimes wonder if it would be a good practice to put an NGINX reverse proxy in front of the Flask App.
and implement the security features in NGINX rather than in Flask

[inland oak]

Well... Why not?

If u find them sufficient

The point of flask Auth only in better flexibility

[timber jungle]

Sorry, i do not understand this.

[inland oak]

flask gives you ability to make ANY auth solution, which will be within same programming language attached for example to database for adding/removing users

or in any other way... you can implement any type of auth

attaching/removing cookies to the sent requests to flask, which will persist auth

or any data you will input to JWT tokens

Flask has 100% flexibility to make any kind of Auth

Nginx will allow only really limited auth, for example i often protect admin services with at least basic auth from Nginx

you can probably try hooking some other auth things, using nginx, but it will be... ugly monstrocity between different kind of systems

in best case, it will be highly likely making only hard coded user system which stores data directly at hard drive where nginx is located

So... really limited options to auth system with Nginx

and consider in addition that you are limited only to FREE version of nginx ;b

if Nginx is enough, sure, do it. But if you need any complexity beyond 1-3 users, better to use flask

[timber jungle]

I was thinking mostly in securing the web app with an Nginx or as a Reverse proxy
Something along these https://www.acunetix.com/blog/web-security-zone/hardening-nginx/

But i see that there are multiple Python modules for doing these ( Talisman Flask, Flask SSLify, etc - the hard part of this, is that i have to find them 😄 )

[inland oak]

Ah, u will need to do it anyway

Because... If u use flask with templating html stuff, u need to serve static files with nginx
And reverse proxing the rest of stuff into your gunicorn server

Although even when using flask as rest, u a still probably required to put nginx in front at least if u wish stuff like before framework caching

[native tide]

any project ideas?

[ornate flame]

I found these good for learning purposes:

• Blog Website with auth, comments and crud.
• Real time messaging app

You could do both of this with either just flask,django etc.. or make an api with that framework and connect with a frontedn like react/next.js(this would make it a fullstack project)

So the code is recognising appNamePost, but then not applying it to appname.

The config for appname is https://paws.aaw.ooo/ewp028.png, and this is what it's setting ti to as an output https://paws.aaw.ooo/ymeegr.png

Need help understanding why.

trying appname=f"{config['config']['appname']}{appNamePost}", also doesnt work

which leads me to believe that something isnt taking the template when it should be

Any ideas?

hi i need help with flask development and sql?

i would like it to post products as a product card here, however, they aren't showing up and not sure why

code for the html layout:

{% extends "layout.html" %}
{% block content %}

help would be greatly appreciated thank you very much

[hollow dragon]

this part:

<img src = "{{ url_for('static',filename='products_pics/' ~ products.id~'.jpg') }}">

take a look at it again

[plain kettle]

i wasn't quite sure how to use images, i was thinking if i make it a sql row as well, and have it stored there

i'm kinda lost

[hollow dragon]

just for testing, put an image into your static folder

then

<img src="{{url_for('static', filename='something.jpg')}}/>

Don't really think you can make a relationship between SQL and an img src command haha

[plain kettle]

ah solid i've got a few pictures already, i'll change the filename to that then

oh wait hold, i decided to change the folder name a while back to just pics

i'll try it now

changed it to 'switch.jpg' and nothing came up

[rugged dagger]

Yo. I need to create a YearOnlyField, and be able to filter by from_year & to_year. How would you do this?

[hollow dragon]

can anyone recommend me a good resource for learning about escaping flask & html?

[velvet terrace]

So I have this XML file, and when parsing with lxml I get element names like {urn:oasis:names:tc:opendocument:xmlns:container}rootfile

I'm trying to match with xpaths on just the rootfile part

[plain kettle]

hi flask users, what does this error mean

{% extends "layout.html" %}
{%block content %}

<h1>"{{product.title}}" &nbsp </h1>
<div class = "item-container">
    <div id = "image">
        <img src="{{ url_for('static', filename= 'pics/' + product.title + '.jpg')}}" width = "400" height = "400">

{% endblock content %}

[eternal kestrel]

@plain kettle hi

show your route response

what are you returning from the route

remove the ()

it's treating product as a function

...or it is a function

[plain kettle]

ah hi thank you for your help

the route is this:

@app.route("/product/<int:product_id>")
def product(product_id):
    product = Product.query.get_or_404(product_id)
    return render_template("product_page.html",title = "Product", product = product)

wait i fixed it

it turns out i mistyped the product as products = Product.query

[hollow dragon]

I've come up with a really good solution: I just deleted the registration option from the app, so there is only login option. I have a user for the app so I'm the only who has access to the content. So it's fine because I can present it during the interview and I won't be able to store any user data outside of it. What do you guys think?

[plain kettle]

thank you for the help @eternal kestrel

hi again stuck on registering

everytime i register on my website, it clears away the password field, seemingly suggesting it does not like the password

@app.route("/Sign_up", methods = ["GET","POST"])
def Sign_up():
    form = sign_up()
    if form.validate_on_submit():
        user = User(username=form.username.data, password = (generate_password_hash(form.password.data,method='sha256')))
        db.session.add(user)
        db.session.commit()
        flash("Sign up successful. Enjoy")
        return redirect(url_for('home'))
    return render_template('Sign_up.html', title = "Sign up", form = form)

this is the routing

{% extends "layout.html" %}
{% block content %}

<form action = "" method = "POST">

    <section id = "username_new">
    {{ form.username.label }} {{ form.username }}
    {% for error in form.username.errors %}
        <span style = "color: red;"> [{{ error }}]</span>
    {% endfor %}
    </section>

    <section id = "password_new">
        {{ form.password.label }} {{form.password}}
        {% for error in form.password.errors %}
            <span style = "color: red;">[{{ error }}]</span>
        {% endfor %}

    </section>

    <section id = "password_confirm">
        {{ form.ConfirmPass.label }} {{ form.ConfirmPass }}
        {% for error in form.ConfirmPass.errors %}
        <span style = "color: red;">[{{ error }}]</span>
        {% endfor %}

anyone have experience deploying flask app on raspberry pi to web?

[outer smelt]

so i was watching corey schafer's tutorial part 2 where he talks about bootstrap and the things he pastes into his code from the bootstrap website is different from what i'm seeing in the website, what do i do?

(flask btw)

[scenic dove]

yeah

i think it is just version differences

[outer smelt]

well do i copy paste corey schafer's version code or do i copy the latest one in bootstrap website

i'm assuming that there wont be any difference in code syntax if i use the newer version?

[forest berry]

I’m making a flask app rn and I’m wondering what’s the best practice for making web apps. When using a database like SQLAlchemy or SQLite3, should I make a REST Api to go along with it? Or is it not necessary?

[dusk sonnet]

hey, how can i go abouts creating sort of pagination for a Chat App ( Using Django Channels) whereby when visiting a chat room, only e.g. 10 messages are loaded and if the user scrolls through the chat log, every time they reach at the top load another 10 and so on depending on how many messages have been saved in that chat room.

[plucky wadi]

Yep , you can create api's with django and drf and deploy it online.

[hexed ether]

okay thanks.

Hello

I am not using Flask Login.
I am using session

Is there a possibility to show an html element only if certain users have logged in?
These users are stored in a database.

[plucky wadi]

Template tags like user.is_authenticated would get the job done ig.

check DRF pagination. I'd implement scrolling with React and call an api every 10 messages

[dusk sonnet]

iv never used DRF and React

Hey. How do I integrate a pdf reader into my website?

Does anyone know any pdf reader plugins? Not any of those comic-like ones

That'll work well with django

[proper current]

is it possible to use pyqts .ui files to build a website instead of directly writing html? at least with flask it shouldnt, but maybe im missing something?

[ionic raft]

My experience is mostly (now) with PostgreSQL and Django. sqlite3 is solid for getting started. But lately, I've opted to connect to a production ready DB (PostgreSQL) even for initial dev work. This saves time in the long run for me. SQLAlchemy is well regarded but I've not used. PostgreSQL is rock solid and scalable in any production scenario. As for making a REST API, that would be use case specific. I could see value in that if I've built a web app, for example, and want to also release an ios or Android app. I get asked a lot about if I've used a REST API, but my experience is doing the Django-tango and working with the ORM. As my experience grows I'm finding that serving me really well. But then, I've not as yet built a web app where an API was required. Is a REST API necessary? That depends. If you want to facilitate something other than your Flask application connecting to the DB, then yes.

[golden bone]

I would say this depends entirely on what you want to do. If you want people to be able to consume your app as a REST API, build one. If you don't, don't. Designing and implementing a REST API is not a trivial task, but it's useful if there is a use case for it.

[golden bone]

There are so many possibilities, I don't have a specific recommendation, but did you see https://stackoverflow.com/questions/14081128/how-to-embed-a-pdf-viewer-in-a-page ?

[forest berry]

@golden bone @ionic raft Oooh ok got it thank you!!

I was also wondering, how come in this Tech w/ Tim vid,

https://youtu.be/f_bml-MILAs

he doesn’t use an API in this case? It seems like the front end needs to make changes to the backend a lot, but he doesn’t use one. Is there any particular reason why? Or is it because he wasn’t planning to deploy the website and so he didn’t use one. I’m guessing if he was actually planning to deploy it, he would have needed to make an API rather than directly communicating w/ the database right?

[ionic raft]

I have not watched that particular tutorial. However, I've seen some of Tim's tutorials and he's quite good. As for your question, at a guess this would come back to the requirement being coded for. This appears on the surface to be a tutorial to walk you through creating a blog web application with Flask. Blog's are a common topic for dev tutorials because they cover core elements of web app development that will lay a good foundation (you will learn about DB and CRUD, using the application layer to work with the DB/presentation layers, and the presentation layer for the end-user to interact with the app). At a guess, I'd imagine he's not using an API because the requirement isn't there. You do not need to craft an API to deploy. I have two deployed web applications, being used by real-world clients, neither of which have an API. The second may end up requiring an API, but only if market demands push for smartphone apps.

[forest berry]

Oooh ok thanks!! I had always thought that if u don’t use an API, it would mean the front end is directly communicating to the backend. Since in the vid he isn’t doing that in this case, how does the front end talk to the backend w/o an API?

[ionic raft]

That's a great question. My learning path to development in Python started with a 100 day boot camp where this was laid out nicely. One challenge with tutorials is that they are focused on a specific requirement and don't often get into the underlying realities. I can speak for Django, but I did spend about 1.5 months with Flask before I went to Django. However, at their heart there is a fair bit of overlap. The simple answer is that the application layer is the middleman. You build an object model to tell the ORM how to structure/build the DB. You build the view at the application level to do the talking with the DB. The view takes care of building web pages to send to the browser (the front end), and receiving user input. Your code at the application layer is really the key part in all this. The application layer (the middle) is what speaks to the back end and the front end.

[grave terrace]

Hey All,

Been fighting with a problem all day and just can't seem to figure out a solution or find one online and was hoping to get some help....

The short and long of it is I'm using flask and wtforms as a front end for a tool I'm building and I'm struggling with dynamic form creation:

I have a python list of devices I pulled from an api and I want to create a form that prints this list and allows a user to select any or all of the items in it and pass the list of selected devices back to be processed against, I have no problem printing the list but can't figure out how to make each item a selectable form field and have it append that item to a new list on submission...

I thought this would be a relatively simple task but either I'm missing something or it's a lot harder to create a dynamic form than i thought

[forest berry]

Oooh got it thanks!! So from my understanding from what u said, using an application layer and an API are 2 ways of going from front to back end. What would it look like just going frontend to database? Would it just be like a user clicks a button and it doesn’t send any get/post requests and it just updates the DB?

[ionic raft]

Indeed, an API and the application layer are two ways of communicating with a DB. I would not advise going directly from the front end to the DB. There are good reasons for the current N-tier approach (presentation-application-data). The main one is focus. The presentation layer shouldn't include logic, it presents. The application layer does the logical grunt work. When you bring logic into the presentation layer things can become challenging.

[forest berry]

That makes sense, that rly cleared things up!! You’ve been a huge help. So does that mean by simply using Flask, flask itself provides the application layer? And also ik going from front end to DB is not recommended, but I was wondering what it would look like code wise (so ik what not to do)

[serene matrix]

I did see this, yes. But none of these give a book-like feel. It's supposed to be used in a library app. And I want to be able to remember last read position

[worthy lake]

I'm a little disappointed that I put so much effort into getting my docker-compose project perfect to throw up django, postgres, nginx, cloudflare tunnel, redis... and now I get started with learning DigitalOcean to find that they don't support docker-compose. They can translate apps made with a Dockerfile into something they all their "App Platform" but like... if I would have known this, I would have spent all this time learning their "App Platform" and not how to get docker compose just perfect

And now im thinking, do I even still want to use Digital Ocean if it cant just deploy from docker-compose directly.

Does anyone have any advice for where I should get my cloud service?
I know that places like heroku and whatever will let you serve a free python app, but Im more interested in learning learning a cloud service that is a little more... reputable for real apps.

I know that i dont want to do Azure. There is what else? AWS? Linode?

[solid hedge]

When you send a link in a discord chat, discord usually just displays the picture / gif associated the link. How is that done? does discord send a get/post request or something to the link and displays whatever it finds?
Just curious
I'd think it would be a waste of resources to be sending http requests to every link someone sends though

[quick cargo]

It's part of a HTML document's metadata

https://ahrefs.com/blog/open-graph-meta-tags/

[quick cargo]

However, yes it does send a request on every link. But it's pretty insignificant overall to do.

[solid hedge]

That's hella interesting thanks much!

[frank shoal]

It does GET. If its content-type is an image, it embeds it. If it's html, it reads the <meta> tags for opengraph properties.
https://www.opengraph.xyz/

[solid hedge]

Thanks!!

[ionic raft]

I stumbled into the exact same realization. In the end though, I opted with Digital Ocean and a Docker Image. The outcome...it is an OUTSTANDING service. I'm using DO for production deployment of Django apps in docker and I am truly blown away with the ease of management. And to be clear, there's not much time needed to "learn" their app platform. If you have a docker image and deploy, it does a very good job.

[golden bone]

You've mentioned the big players except Google Cloud.

I've not used DO but they have VPSs right? You could run Docker Compose inside of one of those. Then if you want to gradually migrate things like the databases out if it makes sense to

I see now someone already told you that, this is why you shouldn't crosspost 😩

[worthy lake]

yeah, i didnt cross post on purpose... I just started here and I realized there was a better place to talk about it after. And I should have edited my old post if was gonna do that but i didnt.

anyway...

the main thing im discovering is that... like a few people have said, the tools they have may not be what I expected, but if I ignore them and work out of docker compose exclusively, im missing out on the power in their services.

i imagine everyone is like that.

Right now i have a mix of cloudflare and DO. I'm gonna stick with it and try to learn how they do things.

[wispy crest]

#web-development so flask ques can be asked right?

[serene prawn]

sure

[wispy crest]

oh thanks...how can the data in a html file be updated without refreshing the page

they say ajax or xmlhttp reqs and stuff

[serene prawn]

Yeah, you have to send request to your backend using javascript if you don't want to refresh the page

[wispy crest]

hm

[inland oak]

I can't imagine using Django as not rest API.
Building Frontend without modern tools, SCSS, Vue. JS is too... Bad path in my opinion. I don't want to have dirty code appearing just because of chosen tools

[native tide]

.NET Core API?

[azure pecan]

hey I am quite new to web dev, I was wondering if anyone knows why I am seeing the horizontal line in the middle of my tables?

could it possibly be I am missing a closing tag or smth

[serene prawn]

Building REST API's isn't necessary if you're using django templates, otherwise if you have some sort of client app (web, mobile, desktop) you in most cases should use rest

[ionic raft]

Agreed. In the early stages of these projects the front end is mobile first. If clients demand them, then apps and rest api will follow.

[serene prawn]

I mean, if you have an app that interacts with your backend you should use rest 🤨

[zealous elk]

I am getting an error in this Flask app that I am working on. The details are in #help-burrito, please help me if you can

[wooden hearth]

Hi, so I have the following question:

Say I have a website for my car dealership

and I want to give the user, the option to "recommend" cars

meaning that say some user wants to sell their car to me, they will enter their email, phone number and the car's model for example

what's the correct way to implement something like this with django-rest framework?

Do I need a separate app for this? If I do then wouldn't that result in code duplication since I will have to rewrite the car model + the user information (email and phone number for example)?

I was thinking of just creating a new class that extends my Car model class and just add user email and phone number in there

and then create a new endpoint /recommend or something which will be connected with that model

is python a good framework for web development. when i say python i mean python not django even tho they are the same thing but i don't think so

[serene prawn]

It is pretty good, but i guess it depends on your requirements

[somber plover]

I hope this isn't needlessly pedantic, but python is a language and django is a web framework for python (one of many).

The question appears to be whether the python language is good for web development. I can only say it appears a lot of people think so. :) I haven't yet embarked on that journey. It will be interesting after many years of suffering with Ruby on Rails.

[golden bone]

Makes sense

[somber plover]

A couple of the strongest reasons to go with RoR were unhelpful in our case (at work) but it was only years in that we realized it. First, ORM (didn't use it - had to make it work with weird OS / architecture at the backend, so ended up hand-rolling our models in a non-ActiveRecord way). And second, the whole notion of an "opinionated framework", while I could see the appeal, actually worked against a lot of things we wanted to do differently. :p

I now believe the "opinionated framework" idea was largely a reaction against some of the flaws baked into Ruby as a language, and the Ruby coding culture at the time.

If I were to rewrite it today in Ruby, I'd probably go more lightweight (e.g. Sinatra) while continuing to use Vue for the front end (as we still do today). In Python (my hobby coding projects, not work), therefore, I'm looking to not repeat that sort of mistake. Therefore, I'm planning a webapp in Django + Vue (or if I'm up to the challenge, React instead, though I'd have to learn that first).

anyone knows why i'm getting this error in django?

TemplateDoesNotExist

when the template does exist

[rigid laurel]

Either the filename is wrong or you haven't set Django up to look in the right place

[golden hamlet]

how do i set django to look elsewhere

it finds a non existing source, it does \templates\templates\

instead of \templates\projectname\

it works normally for other apps

but for this app it can't find the templates for some reason

django was looking for the index.html inside of templates/templates automatically so I just changed the file name from templates/appname to templates/templates

and it works now

[ionic raft]

Regarding the on-going conversation about using a REST API framework for Django verses using the ORM. If you're using the ORM you've got extra layers of protection from vectors such as SQL injection attacks. If you're using a REST API framework you had better be paying extra attention. I found this post very informative. https://www.stackhawk.com/blog/sql-injection-prevention-django/

[kindred coyote]

can some one tell me how i can read the id out of this <button type="button" id="userbtn" class="btn btn-sm btn-danger" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> that i can make my browser.find_element_by_css_selector(" ").click() click it

i got send here from generall chat but idk if thats the right place

[lean owl]

read it how

like literally, you have that HTML as a string, and you want to read the ID?

[neat cave]

I dont know if the web-development channel is the right one but does anyone has experience with the socketio library ?

[kindred coyote]

yes

like i want the programm to click the button but i am to dumb to finde the id of it

[lean owl]

beautifulsoup would be best

[kindred coyote]

i am really new at that so pls dont blame

[lean owl]

but if you literally just need to solve this one problem, you could get away with just some string search operations

[kindred coyote]

ehh and how can i do that

[lean owl]

so like

say we have

a = """<button type="button" id="userbtn" class="btn btn-sm btn-danger" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">"""

you could do a = a[a.find("id=") + 4:]

and that'll get rid of everything before the part where it says id="

[kindred coyote]

ehhh then how

[lean owl]

and then a[:a.find("\"")] would give you the ID

[kindred coyote]

ehhh could u do that fore me

cause idk how to do that and my englisch is bad

so i am not really understanding what u mean

[lean owl]

you can literally just copypaste those three lines of code into a file to see it working

a = """<button type="button" id="userbtn" class="btn btn-sm btn-danger" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">"""
a = a[a.find("id=") + 4:]
result = a[:a.find("\"")]
print(result)

if you put that in a file and run it, it'll print the ID

[kindred coyote]

<button type="button" id="userbtn" class="btn btn-sm btn-danger" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

wait lemme try

how can i runn this

[lean owl]

same way you'd run any python program

[kindred coyote]

i runned it but it dident do anything cause i runned it wrong i guess

[lean owl]

I think you might need to slow down a little and just go through some basic python tutorials/courses before coming back to this problem

it seems like you're lacking some fundamentals

[kindred coyote]

bro pls could u do that fore me i just need that 1 line

i just need to copy paste it in then then i am done

can someone help me send data from my views into django class field (trying to set IntegerField's max_value) during run time....

My Django Template:

{% extends 'main/base.html' %}
{%block title%}Delete List{%endblock%}

{%block content%}
    <form method="post" action="/delete/">
        {%csrf_token%}
        {{form}}
        <button type="sumbit" name="Delete List">Delete List</button>
    </form>
{%endblock%}

my function inside view:

def delete(response):
    if response.method=="POST":
        form1 = DeleteList(response.POST)
        print(f"delete button pressed: {form1.is_valid()}")#just checking
        if form1.is_valid():
            ""
            print("valid form: {}".format(form1.cleaned_data))#just checking
            return HttpResponseRedirect("/display")
    else:
        #form1 = DeleteList(10) -- i want to do this...and use a number to set maxVaue of a field
        form1 = DeleteList()
    return render(response,"main/deleteList.html",{"form":form1})

my django forms class:

class DeleteList(forms.Form):
    #i was trying to make this __init__ work but seems to be buggy
    """def __init__(self,maxValue:int, *args, **kwargs):
        super(DeleteList, self).__init__(*args, **kwargs)
        self.fields['id'] = forms.IntegerField(label="Enter id",min_value=1,max_value=maxValue)
    #id = forms.IntegerField()"""    
    
    id=forms.IntegerField(label="Enter id",min_value=1,max_value=10) #-- only this seems to work

to elaborate , am trying to do something like form1 = DeleteList(10) in my functions inside view and with the int value i pass in there , iam trying to set the IntegerField's max_value on forms class
every time this form runs , the max_value of integerField will to be different
sorry if this seems to be lengthy , do ping me if this is confusing , i can explain
Thank for anyone trying to help 🙂

lots of errors in there but to fix up but the last comment says it all

I'm just gonna conclude with... I tried the deploy config where you have ten million env files.

It sucks. Horrible way to do it.\

im gonna reduce the number of env files to where i know what is coming from where exactly and cant get confused when its importing incorrectly into the conf file as None or something else. Instead there will be several conf files that figure out what goes in place of what after the env is loaded in. Not before.

[frank shoal]

I would suggest putting the router rule in nginx instead.

[lean wasp]

Im very new to server development, can you pls elaborate? So how would the flow look like? FastAPI->Nginx->Other backend servers?

[frank shoal]

it would be nginx -> fastapi, and nginx -> other backend.

[lean wasp]

And how would authentication work in this case?

[frank shoal]

handled by the other backend

What kind of backend is it?

some third party api?

[lean wasp]

GraphQL server(Strawberry)

[frank shoal]

Do you manage it?

[lean wasp]

Yes

[frank shoal]

are you using jwt?

[lean wasp]

That will the backbone of the API

That is the plan

May i pm you, to not flood this channel?

[frank shoal]

using nginx, you would have something like this. ```nginx
upstream backend {
server backend1.example.com;
}
upstream graphql {
server gql.example.com:80;
}
server {
listen 80;

...

location / {
proxy_pass http://backend;
}
location = /graphql {
proxy_pass http://graphql;
}
}

something like that.

[golden hamlet]

as a beginner django user, you guys all seem like geniuses tbh :))

[frank shoal]

https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/

nginx is a server you should definitely look into

You can use it with docker even

[lean wasp]

Thank you!
My use case is a game server and match state is going to be stored on server and the GraphQL API would do the state update. So the incoming requests have to reach a specific server(where the state is stored).
Every match has an ID so... do you think i could make the routing based on this information with Nginx?

[frank shoal]

Why not just host it on a different domain?

[lean wasp]

Sorry, i know what is a domain, but i dont understand why would i do that? So it is a round based strategy game, doesnt require lightning fast responses. Probably there wouldn't be region locked servers, so all requests would go through one "gate"/"entity" (auth and load balancing/routing) and matches would run on servers served through GraphQL API and they would scale if there are too many matches.

[frank shoal]

new domain, like a subdomain. You should be able to do it in your cloud provider.

[lean wasp]

So the game server would send the info to the game clients in which subdomain it runs and after that the client would only send requests to that subdomain?

[frank shoal]

Yes.

for example, minecraft uses several subdomains

[lean wasp]

In this case there is no need for Nginx, right?

[frank shoal]

Yes

[lean wasp]

thanks a lot for the thoughs @frank shoal

[frank shoal]

As an example, minecraft uses status.mojang.com, api.mojang.com, sessionserver.mojang.com, api.minecraftservices.com, sisu.xboxlive.com, authserver.mojang.com

[lean wasp]

Can you recommend an article/page describing this architecture?

[frank shoal]

I use https://wiki.vg

note that minecraft's backend (and client) is proprietary and closed source. Nobody but mojang has access to it.

Hi there
Can someone explain what the point of "defaults" parameter in this example is?
def printer(positional, defaults, *args): print(positional, defaults, args)

It mean something like this:
def printer(positional, default="defparam", *args) ?

If so, and I want to call the function with default value I make call like that:
printer('positional', 'args1', 'args2', 'args3')

Output should be this:
positional defparam (args1 args2 args3) but it is not.
Instead it is:
positional args1 (args2 args3)

This is topic from args, kwargs lessons.

How could I get the browser/machine language with flask?

I didnt quite get how I could use requests.accept_languages where does the request come from? 🤔

well, i know about that one, yeah, but I got this error

So I thought something was imported as requests

[serene prawn]

It should be request, not requestS.
In flask request is a request local variable (it's unique on each request)

[onyx lava]

Could you tell me more about that?

HI, when i try to serialize my datetime field it doesnt end up outputting the same date thats in the database. Anyone know how i can solve this?

class ChatRoomMessage(models.Model):
    room_name = models.CharField(max_length=100)
    user = models.ForeignKey(User, related_name="user_messages", on_delete=models.CASCADE)
    content = models.CharField(max_length=255)
    date_sent = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return f"{self.content} {self.room_name} {self.date_sent}"

    # Must change the time its not displaying right
    def serialize(self):
        return {
            'room_name': self.room_name,
            'user': self.user.serialize(),
            'content': self.content,
            'date_sent': self.date_sent.strftime("%b %d %Y, %I:%M %p")
        }

[dusk sonnet]

So i already have USE_TZ = TRUE, same with USE_L10N and have already set the timezone for TIME_ZONE,

But ye idk why its happening

[native tide]

Trying to get this link , but its returning empy list

[native tide]

No I fixed it
But if u can help me with one more thing 🙂

[serene prawn]

use isoformat:

datetime.datetime.now().isoformat()

Date should be the same, maybe your db browser converts dates into your local time or your django app does that

You can also manually convert it into utc time via .astimezone(tz=datetime.timezone.utc)

[dusk sonnet]

so im talking about this line:

'date_sent': self.date_sent.strftime("%b %d %Y, %I:%M %p")

The format in the database is the exact same as that line however the time for some reason is displayed differently

[dusk sonnet]

in settings.py iv made it so it displays localtime

[worldly bone]

Which is better for fullstack mern or python

[serene prawn]

So, time is the same, just format is different?

[serene prawn]

Use technologies that make sense for your project, don't stick to specific stacks

[dusk sonnet]

the opposite. Time is different, format is the same

[serene prawn]

What's the time?

[worldly bone]

I was asking for to study fullstack ,im a beginner so im in bit of a dilemma that what to choose to persue fullstack web development

[serene prawn]

You're essentially asking if js is better than python, it's not, they have different uses

You can use both mongo and react with python

[dusk sonnet]

wdym?

[serene prawn]

What time you have in db and what python sends you?

[dusk sonnet]

1st is python, 2nd is db

oops

[serene prawn]

What's your timezone?

[dusk sonnet]

AEST

[serene prawn]

Weird, not sure why there's a difference of 2 hours 🤔

Python app is using aest tz?

[dusk sonnet]

iv got it in my settings.py

[serene prawn]

Ah, i see

How did you create your record in db?

[dusk sonnet]

its only 2 hrs if its past 12 for whatever timezone python is using but look here, its AM not PM. these were sent at 6:55 PM

[serene prawn]

Hm, i see

[dusk sonnet]

chat_messages = await self.save_messages(self.room_name, message, get_user_instance)

@database_sync_to_async
    def save_messages(request, room_name, content, user_name):
        messages = ChatRoomMessage(room_name=room_name, content=content, user=user_name, date_sent=timezone.localtime())
        messages.save()
        return messages

[serene prawn]

Is it correct time for you rn though?

[dusk sonnet]

in the database yes, but not what is displayed to the user

like in the above image

this line seems to be changing the time for some goddamn reason and i cant figure out why

'date_sent': self.date_sent.strftime("%b %d %Y, %I:%M %p")

[serene prawn]

You're using django templates?

[dusk sonnet]

ye im using templates offc

[serene prawn]

Hm 🤔

It should convert datetimes to your local time

https://docs.djangoproject.com/en/4.0/topics/i18n/timezones/ Read on timezones in documentation, i didn't work with templates though

[dusk sonnet]

what are u referring to when u say Django Templates ? arent u talking about the html files you create

[serene prawn]

https://docs.djangoproject.com/en/4.0/topics/templates/

[dusk sonnet]

ye in general i am using templates but im not tryna solve this in templates.

[wet dock]

I need a little help

I recently got into flask web dev

and I was working with checkboxes

I'm trying to create this in flask

I made it in tkinter

but

is there a checkbox method to detect if a checkbox is checked?

in flask

in kinter we would have to set the on and off value but how do I do that in flask?

[frank shoal]

flask deals with backend, not html frontend.

You need to use javascript.

if you use jquery, you can do if ($("#check_id:checked").length)

If not jquery, you can do document.getElementById("check_id").checked

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input/checkbox

[wet dock]

thanks

[outer apex]

In what context are you trying to detect if a checkbox is checked?

If the checkbox is part of a regular HTML form submission and you're processing the data within Flask, and has a name attribute set, you can do `flask.request.form.get('<name of the checkbox input>'). It'll return a truthy value if checked or None if unchecked.

As well, if you had a group of checkboxes for a related value and they're using the same name attribute (example is a selection of pizza toppings), you can use flask.request.form.getlist(...) to get all the options checked.

However if you're trying to detect outside of a form submission within Flask, and say you were trying to toggle DOM elements depending on a checkbox's status, then as others mentioned, you can use regular JS, JQuery, or even HTMX.

[torpid juniper]

hey every one does any one know how do i catch exceptions onflask_apispec use_kwargs decorator ????

[frank shoal]

!d flask.Flask.errorhandler

[lavish prism]

flask.Flask.errorhandler

errorhandler(code_or_exception)```
Register a function to handle errors by code or exception class.

A decorator that is used to register a function given an error code. Example:

```py
@app.errorhandler(404)
def page_not_found(error):
    return 'This page does not exist', 404
```  You can also register handlers for arbitrary exceptions...

[frank shoal]

use that.

What are the best languages for front and end developement?
Also, could you suggest any youtube course (any length) for web developement?

[native tide]

Also I have heard Django isnt really great when it comes to back-end developement what do you think about that?

Hii. Question. I'm making a web app where a user can upload a sudoku puzzle image and the backend solves and returns the solution on the web page. My question is would that change be reflected to all users? How do I make it so that the specific user is returned his specific solution. Can anyone shed light on this?

[golden bone]

You have many options but if you want things to change dynamically on the same page, you're most likely going to need some form of JavaScript.

[terse ermine]

Yes but I mean say you upload an image of some sudoku. Backend solves it and dynamically updates the page. Would I (another user) see your solution? How would i make it so that you see your solution, and I see mine.

If that makes sense lol

I just figured it out. Thank you!!!

Hi...does any one know any frameworks or work arounds to enable live or on demand streaming possible while using storage buckets to hold the video files

[dusk sonnet]

Hey im having an issue relating to DateTimeField in django. I use timezone.localtime() when saving objects into the database in order to display the correct time for my location. I have the following enabled in settings.py TIME_ZONE = 'My location', USE_L10N = True, USE_I18N = True, USE_TZ = True. The problem that im having is that in the admin dashboard, the time is displayed correctly and as intended however when i query in python to get certain objects, the time is printed out in UTC even tho im querying from the database. 1st image is essentially the result when querying from the database, 2nd image is viewing the same object/message from the admin dashboard.

[elder nebula]

There's WebRTC for django if you want to use live streaming, I think it allows VODs too

It might be just what you want.

I am trying to create a todo list in Django, when I want to delete an item, I have to create another html page for deleteing it.

hey guys

i have an 'edit' function in my web app, which just allows me to edit the input value from the SQLAlchemy table, so basically the rows, for example the 'title' of an object.

It works perfectly fine, except for the first item

So I can use the 'edit' function on all the items except the first one

Have no clue why

[hollow dragon]

edit: solved it

[delicate coyote]

does somebody has an Idea how to make a bidirectional client Python/Web and the Server Python Flask. There are framework like socket.io, signalR, which would you recommend?

I don't maybe WebRTC works for flask i have not idea.

Heyho,
i hope im am correct in here with django and an sql issue 😄

I am trying to add an String "Name" and an Int "ItemID" into an model and into the database.

My Model is this:

    itemid = models.IntegerField()
    name = models.CharField(max_length=50)

    def __str__(self):
        return f'{self.itemid}'```

Everytime i run

new_item.save()```

it shows Field 'itemid' expected a number but got 'New Item'.

If i run
new_item = items(1, 123456,"New Item")
it works

After opening sqlite db with dbweaver, i see an column called ID. Shouldn't be the column autoincrement?

[lapis spear]

i have these code

from django.db import models
import uuid


class User(models.Model):
    id = models.UUIDField(
             primary_key = True,
             default = uuid.uuid4,
             editable = False)
    lastname = models.CharField(max_length=100)
    firstname = models.CharField(max_length=100)
    mi = models.CharField(max_length=20)
    age = models.IntegerField()
    gender = models.CharField(max_length=20)
    birthdate = models.DateField()
    vote_status = models.BooleanField(default=False)
    poll_status = models.BooleanField(default=False)


class News(models.Model):
    id = models.UUIDField(
             primary_key = True,
             default = uuid.uuid4,
             editable = False)
    title = models.CharField(max_length=100)
    headline = models.TextField(max_length=300)
    content = models.TextField(max_length=2000)
    date_posted = models.DateField(auto_now_add=True)

class Comments(models.Model):
    id = models.UUIDField(
             primary_key = True,
             default = uuid.uuid4,
             editable = False)
    user_id = models.ForeignKey(User, on_delete=models.CASCADE)
    news_id = models.ForeignKey(News, on_delete=models.CASCADE)
    comment = models.CharField(max_length=500)
    date_posted = models.DateField(auto_now_add=True)

and this table relations

for these 3 tables the user,news, and comment did i implement it correctly on my code?

Can anyone recommend a good tutorial for building a basic website with Flask, where they also build the HTML and CSS from the ground up? Lots of the material I see online has pre-made templates, or they are copy/pasting code snippets and I'm not learning much from that. I want to learn how to cook, not just follow a recipe, if that makes sense.

[delicate coyote]

freeCodeCamp.org has lots of video content on youtube. and check the official website. first make sure you want to learn with template or REST. This are two different aproaches

Thank you, I will look there. I'm not familiar with REST, I'll have to do some research...

[brave grail]

I'm making a flask app

...and wondering if there is some way to dynamically choose dimensions for an image that is generated for a html page so that it fits on the screen?

For my specific example, I am making images from pdf file. (just the first page) ```py
def pdf_preview_image(pdf_path, image_destination):
"""

:param pdf_path:
:param image_destination:
:return:
"""
# Turn the pdf filename into equivalent png filename and create destination path
pdf_filename = split_path(pdf_path)[-1]
preview_filename = ".".join(pdf_filename.split(".")[:-1])
preview_filename += ".png"
output_path = os.path.join(image_destination, preview_filename)

# create png preview and save it
fitz_doc = fitz.open(pdf_path)
first_page_pix_map = fitz_doc.load_page(0).get_pixmap()
first_page_pix_map.save(output_path)
return output_path

fitz is like a pdf library

pdf files range from 8.5x11 to 42x36 so the images can be quite big.

[outer apex]

If you already had / willing to make different image files for the different dimensions and you're okay with the different image by width breakpoints, you could use a picture element with a few sources

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/picture

[brave grail]

I guess I'm wondering if there is a way to determine the user screen size so that I could adjust the dimensions likewise. Or is there like a standard image size web developers consider a maximum size?

If I have a registration form for users, is it safe if it only has "username" and "password" section in it? I removed the "email" section.

Or storing any user data is always unsafe?

I mean, only "username" and "password" shouldn't be personal data, right?

Or just use Two-factor auth ?

hello,, iam trying to refer this documentation: https://bootstrap-table.com/docs/api/events/ and try to make a jquery for my bootstrap table , it just wont work at all

after reading the docs i came up with this: but this never seems to work

$('#display_table').bootstrapTable({
    onClickRow: function (row, $element, field) {
      alert("testing");
    }
})

anyone here used jquery with bootstrap ? and know how to get a row clicked listener (sort of)...?

[somber plover]

dunno. it's not just you. doesn't work for me either. try chaining .on() from the bootstrapTable() object instead.

$('#display_table').bootstrapTable().on('click-row.bs.table', function (e, row, $element, field) {
  alert("testing");
});

note as per the API doc, e (the event itself) is passed as the first argument with this form.

[somber plover]

i don't use it. but might have a solution for you above.

[ruby tree]

Ahhh

[somber plover]

once upon a time, i used to use jQuery. don't anymore. it has all been replaced with vue + webpack + babel

[ruby tree]

I wish the stuff they put in the docs would just work just like that

Alright let me try what u posted

[somber plover]

checking their issues ...

[ruby tree]

https://stackoverflow.com/questions/26567867/bootstrap-table-cannot-add-click-event-on-tr

this is a old answer ^ but this seemed have worked for them

maybe something got changed in recent years , idk

[somber plover]

https://github.com/wenzhixin/bootstrap-table/issues/4878

this.

dunno what that's all about though ... i'm just using the "getting started" example code and in the jQuery load handler, attach the bootstrapTable there. ... no vue at all.

[small linden]

I’m trying to click a button on a webpage with selenium, but for some reason I cannot find any element in the page

It either says stale element or element not found

[ruby tree]

iam trying to make my code similar to a example visible on that link u posted , will update !

[somber plover]

you mean the "welcome.html" they linked?

i only see the .on() form in there, too. but nowhere in the doc explains why onClickRow no longer works if you aren't using Vue. :p

[ruby tree]

oh

[somber plover]

i think it's just a doc bug, then. the Events page talks about there being two ways to do it. the first way via "options" and the second with on(), but if you look at the Table Options page it doesn't list any of the on* events as being options anymore. https://bootstrap-table.com/docs/api/table-options/

[ruby tree]

mhaaaa i got it to sort of work via vue

<script>
new Vue({
    el: '#table',
    components: {
      'BootstrapTable': BootstrapTable
    },
    data: {
      columns: [
        {
          title: 'Item ID',
          field: 'id'
        },
        {
          field: 'name',
          title: 'Item Name'
        }, {
          field: 'price',
          title: 'Item Price'
        }
      ],
      data: [
        {
          id: 1,
          name: 'Item 1',
          price: '$1'
        }
      ],
      options: {
        search: true,
        showColumns: true
      },
      onClickRow() {
          //on click row
         alert("testing");
    }
    }
  })
    </script>

so now this onClickRow() functions would get called everytime a row is clicked on

but i still dont know how to access the values tho , testing

[somber plover]

Vue is certainly nicer. looks like progress! :)

[ruby tree]

 onClickRow(row, $element, field) {
         alert("field:"+field+"-"+"row.name:"+row.name+"-"+"row.id"+row.id);
    }

@somber plover thanks , this seems to work for now

so apparently onclickrow works on vue

and not on js i have no idea

but seems to work for now

[somber plover]

shrugs

that's great!

[ruby tree]

<div id="table">
            <bootstrap-table :columns="columns" :data="data" :options="options" @on-click-row="onClickRow"></bootstrap-table>
          </div>

this is how i create the table for it to work with vue ^

but there is one big problem here

[somber plover]

it is a heck of a lot less mysterious to have the handler explicitly put in the template like that ...

[ruby tree]

:data="data" ...... iam creating data on vue and i hope there is some way to just use my old html tables oops

[somber plover]

than the more mysterious binding on load of the handler when the table is instantiated

personal taste.

(and is one of many reasons why I no longer directly write jQuery ;) )

[ruby tree]

haha

and this is the js

new Vue({
    el: '#table',
    components: {
      'BootstrapTable': BootstrapTable
    },
    data: {
      columns: [
        {
          title: 'Item ID',
          field: 'id'
        },
        {
          field: 'name',
          title: 'Item Name'
        }, {
          field: 'price',
          title: 'Item Price'
        }
      ],
      data: [
        {
          id: 1,
          name: 'Item 1',
          price: '$1'
        },
        {
          id: 2,
          name: 'Item 2',
          price: '$2'
        }
      ],
      options: {
        search: true,
        showColumns: true
      },
      onClickRow(row, $element, field) {
         alert("field:"+field+"-"+"row.name:"+row.name+"-"+"row.id"+row.id);
    }
    }
  })

it works , i just need to experiment with it for sometime to learn how it works... all i know rn is it just works like magic , iam new to vue , this is goona be interesting

I got a take home project to create a chat application in Django and I built it using channels following channels documentation tutorial but I'm quite confused on how to make them secure(end to end only)
This is what the requirement said:

Third part of this project is for you to make this web socket secure. You don’t have to add any certificates to make the protocol ‘wss’ instead of ‘ws’. But you have to come up with a way to make sure just using the socket link no third party can see the streams. That mean you have to add a layer of security to view the stream.

I've looked into https://channels.readthedocs.io/en/stable/topics/security.html but I don't think that is it, would appreciate if anyone could push me in the right direction.

hmmm

guys, in my django project , i have a js function set up that would trigger based on clicks from a bootstrap table, so the part visible on the code is only of importance here , iam looking for ways by witch i can delete id received in this function ,, can someone help me go in a correct direction -iam clueless as of now

..
...
.....
else if($(this).data("delete-id")){      
id=$(this).data("delete-id");
alert("delete clicked: "+id);  //was just testing to see if it works and it works..

//in here i need to make some way to connect to my django models and delete that perticular id...
}

i have already setup a delete page and this is the view function for it :

def delete(response):
    temp = models.ToDoList.objects.all()
    max_id=0
    for i in temp:
        max_id=i.id
    
    if response.method=="POST":
        form1 = DeleteList(max_id,response.POST)
        if form1.is_valid():
            "if valid input , then delete that id"
            temp.filter(id=form1.cleaned_data["id"]).delete()
            
            return HttpResponseRedirect("/display")
    else:
        form1 = DeleteList(max_id)
    return render(response,"main/deleteList.html",{"form":form1})

i think the way to go forward is to somehow make my js function do a post method so that i can just handle it in my delete views function .... is this correct ? how do i do this btw

How can I have two OneToOneFields in a single Django Model?

This works:

from django.db import models
from django.conf import settings


class FriendRequest(models.Model):
    author = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True)

This doesn't:

from django.db import models
from django.conf import settings


class FriendRequest(models.Model):
    author = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True)
    recipient = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True)

The second one throws:

interactions.FriendRequest.recipient.
interactions.FriendRequest.recipient: (fields.E304) Reverse accessor for 'interactions.FriendRequest.recipient' clashes with reverse accessor for 'interactions.FriendRequest.author'.
        HINT: Add or change a related_name argument to the definition for 'interactions.FriendRequest.recipient' or 'interactions.FriendRequest.author'.

First, you open your ports

Local, firewall, router, etc

Maybe do some port forwarding (ports 80, 443 TCP)

(optional) assign a dns name to your public ip

Hello guys, how can I run my python script in web asynchronously (Without refreshing the page). Can it run on ajax?

[frank shoal]

Use JavaScript to poll your endpoint and update the page dynamically using the DOM api

[native tide]

Hey, i have a django webserver where certain code does not run on my production server but it does run on my machine. I have isolated some things that cause the error, but cannot get django to write the error log to a file, somehow. When i allow error logging, it just causes all of my requests to return an error 500...
what do i do?

It also just does not log
this is my logging config

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': '/var/www/debug.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

What are the differences/benefits to using aiohttp's websocket support vs using websockets?

[regal lotus]

resp = requests.get('https://wax.api.atomicassets.io/atomicmarket/v1/assets?collection_name=nfsocialexgg&schema_name=nfse&page=1&limit=1&order=desc&sort=asset_id')
data = resp.json()
asset_id = data['data']['asset_id']
print(asset_id)


### And the error I get is 

TypeError: list indices must be integers or slices, not str

The Json response is too long to post here. But it's in the readme

[ashen yew]

#help-avocado Figured someone from here could help me out

[mental summit]

data["data"] is a list of dictionaries. Each one has an asset_id.

What do I need to know to make a website that is accessible on the internet?

[golden bone]

If you're not asking how to violate laws or ToS, then yes

[golden bone]

If that's literally all you want to do, you need to know how to open a browser, type and click and that's about it. Wix, Weebly, Squarespace, etc. require nothing more than that.

[native tide]

No

Like there is a page with some words

And I need to take these words

[golden bone]

There are various tools you can use depending what you need to do exactly... here's a relatively simple approach: https://timber.io/blog/an-intro-to-web-scraping-with-lxml-and-python/

Hello

[native tide]

What do people use for deploying django projects for free?
Ive been trying to get Heroku to work for hours upon hours and it just isnt working, does anyone have any good alternatives or can anyone help me troubleshoot my problem?

[native tide]

I use pythonanywhere for small scale projects, good for testing before moving to a higher solution

No matter what I do I always get the same error:
Heroku will not recognise django_heroku

Ive gone through two tutorials multiple times, looked at probably 20+ forum posts, nothing has worked, the error message never changes

Its in the requirements.txt file

Ive tried django-on-heroku

Every single person who gets this error message online seems to have a different problem and different solution so it may possibly be the most unhelpful error message ever made

Are you talking about this?

import django_heroku
django_heroku.settings(locals())```
Because yes I have this

I also included it in the requirements.txt file

I also installed psycopg2 and psycopg2-binary which apparently you need

i know you have it in the requirements.txt file but do you need to run a console command in heroku?

like pip install -r requirements.txt?

Ill try it

it's what I need to do on pythonanywhere, heroku might work differently

(ostexp2) osboxes@osboxes:~/ostexp2$ pip install -r requirements.txt
ERROR: Could not find a version that satisfies the requirement apturl==0.5.2 (from versions: none)
ERROR: No matching distribution found for apturl==0.5.2```

Weird

Is this normal?

[jaunty depot]

hey guys
I'm not sure if I understand correctly the documentation - I wanted to ask, if I wanted to make a django project that is connected to mysql database, do I need to make a User model as well, so that it will be migrated to mysql database? I'm reading, that Django by default contains "User" model in it, but will it also be available when using outer (not sqlite3) database?

[golden bone]

I don't think you need a Django user to run the migration, did you try it?

[jaunty depot]

no no, I'm not building the project yet - I'm just finding out and reading about it. I wanted to make a project that will allow registration of new users, logging in/out etc

and just wanted to know how does that work, that Django offers built-in user models

I know that I will build some other models and wanted to know how it will cooperate

[golden bone]

Your User model will be stored in whatever database you use, shouldn't matter

[jaunty depot]

ah, okay, so now I know
thanks!

I want to have an img with a caption, so I tried <figure><figcaption>.  But <figure> implies the end of a <p>, where <img> does not.  Is there a way to add a caption to <img>, or to keep the inline nature with <figure>?  I know I can style it display:inline-block, but HTML validators complain, and it's parsed as if it ends the paragraph.

[serene matrix]

Maybe wrap the img in a div and put your caption in a <span> and then style their classes how you like

Where do you guys put your process-codes(I don't know if that's what it's called)?

For instance: a function that sends an email.

Do you just drop them in views.py or do you put them in utilities.py?

[agile pier]

what does ur requirements.txt file contain?

[granite lintel]

ive got a question, is flask better than django or not

[serene matrix]

The required dependencies for your app to function as intended

[serene matrix]

They say flask is for small projects. Django is godzilla. I've never tried flask but I know just how 'zilla django is

[native tide]

they are both good but for different purposes. I would say that flask is better suited to "lightweight" applications and the more complicated it becomes then the more you want django

[agile pier]

I know the use of requirements.txt file.
I was asking for trying to help him, maybe he left some dependency

Hi everyone, does anyone have good knowledge of deploying Django on heroku using waitress as the web server on windows. It's almost seem impossible

[nova garnet]

How can I use this
chart.labels().format('{%Name}');
in Flask? I’m following this tutorial https://www.anychart.com/blog/2020/11/11/venn-diagram-javascript/ but using '{%Name}' gives me an error.

[lavish prism]

Hey @hollow shell!

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

[native tide]

The tutorial is for javascript

[nova garnet]

I have JavaScript in my html and I’m running it with Python flask

[native tide]

in python format is used like this chart.labels('{}').format(what_wanna_put)'

[nova garnet]

Also I actually don’t understand the variable {%name} in the tutorial. Where does it come from? Is it from what’s inside data?

[rigid laurel]

try using a lowercase n in name

chart.labels().format('{%name}');

https://docs.anychart.com/Basic_Charts/Venn_Diagram

the name comes from the data you define above presumably

but this is specific to whatever random graph library this is - not anything more generalisable

[nova garnet]

flask doesn't seem to like chart.labels().format('{%name}'); so now I'm trying the suggestion of abstract

[rigid laurel]

oh it's obvious why

the {% is being mistaken for the opening of a Jinja tag

https://stackoverflow.com/questions/25359898/escape-jinja2-syntax-in-a-jinja2-template

{% raw %}
chart.labels().format('{%Name}');
{% endraw %}

trying this:

I'll try this now

it works but I'm still not getting a tooltip when hovering over the diagram with my mouse... I'll try copy pasting the whole thing with the {% raw %} {% endraw }

I finally got it working! thanks a lot!

I figured out why i didn't see a tooltip. apparently I can't have a transparent background AND a tooltip

[nova garnet]

turns out i can have a transparent background with tooltip. just had to use chart.background().fill('white',0); instead of chart.background().enabled(false);

Im using Django
My website is used for seeing all songs in game soundtracks
I have it so if the url is ' ' then it directs to index.html
And if the url has anything else it attempts to find all songs from whatever it got ( 'url/game_name/' gets all songs from game_name)

I want it so if the game does not have any songs then it redirects to index.html
Heres what I have:

from django.shortcuts import render
from django.http import HttpResponse
from .models import Game, Song

def AllGames(request):
    return render(request, 'index.html', { 'games' : Game.objects.all() })

def GameHTML(request, game_name):
    allsongs = Song.objects.all()
    game_songs = []

    for song in allsongs:
        if song.game.name == game_name:
            game_songs.append(song)

    game_songs.sort()

    #Problem Area:
    if (game_songs.count == 0):
        return render(request, 'index.html', { 'games' : Game.objects.all() })

    return render(request, 'songs.html', { 'game_name' : game_name, 'all_songs' : game_songs})```

If you can see the problem thats great but if not does anyone know a way to write stuff to a console or something so I can check game_songs.count whenever I try putting in a url?

Forgot to mention my problem is that if (game_songs.count == 0) never gets called when it should

I added this but I dont know where it shows up, its not in the web dev tools

logging.basicConfig(level=logging.INFO)
    logging.debug(game_songs.count)```

[paper yacht]

who teach you to name function using camel case?

[paper yacht]

your logic is wrong. I'll do it in my way, recieve specific game by id and after that retrieve the song using get_or_404 and then if there's no song redirect to html page. I suppose that the relationship of DB is one-to-many? So why you don't use it?

[native tide]

Whats DB?

Database?

I think its many-to-one not one-to-many as well

All songs store what game they belong to

A game can have multiple songs

[paper yacht]

game can have many songs, so one-to-many

[native tide]

Alright so Im not sure what you want me to do

So your saying I can find the ID of the game_name
Then using get_or_404 I can filter through all songs which have that ID in them

Maybe something like this?

def GameHTML(request, game_name):
    game_ = Game.objects.get(name=game_name)

    game_songs = get_object_or_404(Song, game=game_)

    game_songs.sort()

    if (game_songs.count == 0):
        return render(request, 'index.html', { 'games' : Game.objects.all() })

    return render(request, 'songs.html', { 'game_name' : game_name, 'all_songs' : game_songs})```

get_object_or_404 seems to throw an exception if it returns multiple songs which is what I want

#web-development message

pls

i need help

[paper yacht]

yeap, but pass to get_object_or_404(Song, pk=game_.id) and Game.objects.get(pk=pk) why you passed the name of the game?

and what the purpose of sorting the songs?

[native tide]

What is pk?
Im sorting them so when they are in order on the website

[paper yacht]

primary key of your table

[native tide]

Should I be changing this?

urlpatterns = [
    path('', views.AllGames),
    path('<str:game_name>/', views.GameHTML)
]```

[paper yacht]

or if you're use this url mapping so there's no need to change

[native tide]

game_songs = get_object_or_404(Song, pk=game_.id)```

This only returns one song and throws an error when I try to sort it

Cant I do something more like this

game_songs = Song.objects.filter(game=game_)```

[paper yacht]

yes

[native tide]

Cool, just need to figure out how to sort a QuerySet now

[native tide]

Does anyone see anything wrong with this search bar?
When pressing the button it just reloads the page with url 'server.com/?'

<input class="form-control me-2" type="search" id="gameSearch" placeholder="Search for a Game" aria-label="Search">
        <button class="btn btn-outline-success" type="submit" onclick="Find()">Find</button>
        <script>
            function Find(){
                var input = document.getElementById("gameSearch").value;
                window.location.assign(`${window.location.hostname}/${input}/`)
            }
        </script>```

[sudden sierra]

Maybe you don't need type="submit" if you're not submitting anything?

[native tide]

Unfortunately that didnt change anything, whenever I press the Find button I get this error:

[frank shoal]

Usually a search is done like this via a normal form. ```html
<form action="/gameSearch">
<label for="gameSearch">Game Search</label>
<input type="search" name="q" id="gameSearch">
<input type="submit" value="Search">
</form>

Submit will send the user to https://<hostname>/gameSearch?q=<searchstring>

[native tide]

What is name=q referring to

[frank shoal]

its naming the input. it's determines what query string to use.

in this case, ?q=value

where q is the key

[native tide]

Ill try it

[native tide]

So when I search I get:
/?q=value
How do I get rid of the ?q= part so its just
/value

[frank shoal]

What are you using on the backend?

[native tide]

Im not 100% how to answer that but I think VSCode, Django, SQLite and PythonAnywhere

One of those is probably the answer

[frank shoal]

django, then use request.GET.get("q")

[native tide]

Where do I put that?

[frank shoal]

in your endpoint for /gameSearch

[native tide]

In <form action=... ?

[frank shoal]

no, in your backend.

You know how to define an endpoint, yes?

[native tide]

No Im not sure

I mean maybe I do and I just dont know what its called

Very new to web dev

Is this what you meant?

urlpatterns = [
    path('', views.AllGames),
    path('<str:game_name>/', views.GameHTML),
    path('?q=<str:game_name>/', views.GameHTML)
]```

Doesnt seem to work so I guess not

[paper yacht]

for last expression you shall enable regex r'?q=<>/'

[native tide]

Still doesnt seem to work

urlpatterns = [
    path('', views.AllGames),
    path(r'?q=<str:game_name>/', views.GameHTML),
    path('<str:game_name>/', views.GameHTML)
]```
For the regex one, is the string meant to be all red except for the ? which is orange?

Am I supposed to use re_path?

Something like this? I really need help

re_path(r'(?q=<str:game_name>)/', views.GameHTML),```

|

Let me start again

Im trying to make a search bar
This is my HTML:

<form action="/gameSearch">
          <label for="gameSearch">Game Search</label>
          <input type="search" name="q" id="gameSearch">
          <input type="submit" value="Search">
        </form>```
When I use it the url ends up as:
```hostname/?q=value```
I want it so it either ends up as:
```hostname/value```
Or a way to modify this so the first url works:
```py
urlpatterns = [
    path('', views.AllGames),
    path('<str:game_name>/', views.GameHTML)
]```

how long it took?

[paper yacht]

don't remember

[olive hazel]

can u guess months?

[native tide]

Still looking for an answer to this but in the meanwhile for this code why does the {{ game.img }} work but {{ game.color }} doesnt?
Says it wants a property value:

{% for game in games %}
            <div class="col">
            <div class="card" style="width: 13rem; background-color:{{ game.color }};">
                <div class="card-body">
                    <img src="{{ game.img }}" class="card-img-top" alt="">
(Removed, unimportant)
        {% endfor %}```

[paper yacht]

@native tide do you have color attribute in Game model?

[native tide]

Yep

class Game(models.Model):
    img = models.CharField(max_length=2083)
    name = models.CharField(max_length=255)
    song_count = models.IntegerField()
    description = models.CharField(max_length=2083)
    color = models.CharField(max_length=10)

    def __str__(self) -> str:
        return self.name```

Anyone know of any servers where I might be able to get more answers? I mean I would think these are like noob beginner questions

Hello guys, for updating a ressource on django (non REST framework), would you suggest a post or a put request?
Is it best practice to make CRUD operations even on an app that is not an API?

[native tide]

@native tide You are not using "count" method the intended way. list.count() counts the number of occurrences of an item in a list. https://www.w3schools.com/python/ref_list_count.asp.
I would suggest you use len() method, instead of count()

@native tide Such as: if len(game_songs) == 0:

i need someone to point me in the right direction, I want to create a webapp that essentially takes an upload from the user(which is stored temporarily and deleted after processing) (pdf, doc, txt file) and well reads some text and spits some output out, I need to know what technologies are involved in the taking upload part

[viscid bough]

Sonds crazy.. When its full stack

[frank shoal]

if it's cloud based, I would start with creating a S3 bucket to store uploads.

basically have a web server that accepts uploads and stores them in S3, then have a worker (like celery) connected to a store like redis or rabbitmq

[glacial wigeon]

ok so I'll need s3, django and a domain?

i dont know much about webdev, a c++ coder here

[native tide]

That is quite broad. If you're using django, you could store the files in a media folder. It would be achievable with django I/0 operations. Depending on the magnitude of users you could use aws or heroku. I think you should be good with heroku as a start. Since heroku serves static files, and takes care of the domain

[frank shoal]

a process to accept uploads, a place to store them, and a process to process uploads individually

[native tide]

Django - Docker - Heroku

[glacial wigeon]

yeah thats what I need

is heroku better than the s3 free tier?

[frank shoal]

heroku doesn't come with storage.

it just comes with a database (postgres)

I personally use both

[glacial wigeon]

i see, i'll learn a bit of s3 tom and see if it fits the bill

probably will

[frank shoal]

note: s3 charges for bandwidth, not storage space

I believe internal access (i.e. from aws servers) is free.

Has anyone encountered this error before , "<static_files> was blocked due to MIME type {"text/html"} mismatch {X-content-options : nosniff)
Tech stack : django app running on docker with nginx as reverse proxy and gunicorn as my web server.

[verbal surge]

Hi everyone! I would like to try using Python instead of JS for web development. I've seen Django, Flask, and FastAPI mentioned, but does anyone have a recommendation for which one I should start with?

[plucky wadi]

I started with Flask and i'm now using Django.

[verbal surge]

How do you like both of them?

[plucky wadi]

Django has a lot of built in features. I'd prefer you use it.

[verbal surge]

Thanks for the suggestion! I'll definitely look into it

[verbal surge]

Good to know! Thanks for the info

Does anyone know how to save a todo list to local storage

[past cape]

how do you get "Connection is secure" for your website?

like this

ping when replying, thank you

[whole crow]

you need an SSL cert, which these days you get from Lets Encrypt, which many hosts can do for you.

[pine yew]

TLS* SSL is a deprecated technology where sadly the name keeps getting reused everywhere

[past cape]

ah okay, thank you

[pine yew]

basically Google pays someone like Symantec to give them a certificate (where Symantec is the certificate authority [CA]) and Google uses that to encrypt the the traffic they serve to you using HTTPS (HTTP over TLS).

This is seen as secure because 1. you trust the CA, 2. they've established their identity with the CA so you know they served the traffic

there's a lot more complexity when it comes to CAs and certificates, but that's the gist of it

what "trust" breaks down to usually is which vendors the operating system vendor has established trust with and includes their root certificates in your OS certificate store

[past cape]

make much more sense

ty sir, appreciated

[pine yew]

or something like Firefox which includes its own certificate store

or Java which provides its own store as well (usually inherited from the OS, though)

[past cape]

so they can just approve themselves as certified?

[pine yew]

not usually what happens, there's usually a chain of trust

[past cape]

ah right

im not gonna keep asking questions, but i got the gist of it, ty

[pine yew]

but anyways, the easiest way to serve HTTPS traffic (and thus get the "trusted" lock for your domain) is to subscribe to Let's Encrypt service which can auto-renew your certificates and hands them out for free @past cape

[whole crow]

@pine yew what is the right word to use instead of SSL?

Hi, is there an option to use django admin panel while having ONLY an in-memory database?

Does anyone know how to set var(--color) as game.color here?

{% for game in games %}
  <div class="col">
    <div class="card" style="background-color: var(--color);">

    </div>
  </div>
{% endfor %}```
Usually Id use {{ game.color }} but it seems theres special rules when inside CSS

Redis is an in memory database. I don’t know if there is a Django extension for it though

Can someone please suggest me some Flask projects. I'm a beginner in Flask. Thanks in advance 🙂🌟

Let's encrypt is a hard way
Just use Cloudflare, it has it as inbuilt feature to have verified certs
U need to have self signed certs active at your address though

How is it that websites have custom links for every profile? For example, if I visit someone's profile on IG or FB, they have custom links to their profile that is unique to them, how can I implement the same system into my own flask website?

[zealous elk]

Any idea that you have. The only restriction you should give yourself is that it shouldn't include stuff other than webdev, for example, algorithms. If it is an idea you came up with, even better.

[wet hinge]

maybe make a basic CRUD

[gritty vapor]

Are you talking about : www.fb.com/person-xyz-(random alphanumeric characters)/ such links ?

[zealous elk]

Yes

[gritty vapor]

Basic CRUD like student registration something?

[wet hinge]

not sure how new you are, you might start with a very, very basic CRUD, just to communicate with a database

and build more advanced ones later

to-do app could be the very very basic CRUD

just a simple list with buttons to add a task, edit a task, delete a task

no fancy stuff

no user login

then you can make one with user accounts, each user would have his own to-do list, @gritty vapor

Hey folks, I'm looking for an old Python 2 project that I can run in a test environment to practice migration to Python 3. I'm working on a migration of a legacy app at work, and I want to try out some techniques I've learned recently. Anybody have any antiques they are willing to share?

[candid meteor]

what r some things i should remember before shutting down my website considering that i will later host it again in some time

digital ocean btw, i want to stop hosting and continue exactly where i left in a year or two

Because everything is chrome in the future.

[proven hawk]

Make sure tests exist to make your life easier.

Indeed, that is something that is a part of any good migration. 100% agree.

[golden bone]

yes, there are loads of cut-and-paste tutorials like this: https://realpython.com/flask-by-example-part-1-project-setup/

[hollow dragon]

ah thank you, my app is finally done, all i need to do is to dockerize it

[golden bone]

I assume you mean programatically, with Python via SMTP... Does this no longer work? https://geekflare.com/send-gmail-in-python/

[deft osprey]

Yea sorry that's exactly what I mean, on 5/30 Google decided they would no longer allow "less than secure apps" which smtplib falls under I guess

[hollow dragon]

damn tho, deploying can be so freaking complex

this might be the best one so far https://youtu.be/ZVtv_JkF72M

[austere isle]

how to fix this error , in the tutorial of cs50 the instructor didn't do anything on the file settings.py > templates and it worked for him but for me this error occured

[novel stream]

how's your TEMPLATE set in your settings.py?

[austere isle]

actually i am a beginner

[austere isle]

i didn't set anything on templates

[novel stream]

no worries on that, everyone were a beginner at same time 🙂

[austere isle]

i just made a folder named templates in the project and made a folder named home and in that i have written the html file

[austere isle]

yes 😇

[novel stream]

what I think you're missing is to setup the DIRS key in your TEMPLATE. Could you show us how's your BASE_DIR being generated? It's in the same file and usually at the beginning of the settings.py

[hollow dragon]

im tryna run my docker container and this is what I get:

[2022-06-08 11:40:15 +0000] [9] [INFO] Worker exiting (pid: 9)
[2022-06-08 11:40:16 +0000] [7] [INFO] Shutting down: Master
[2022-06-08 11:40:16 +0000] [7] [INFO] Reason: Worker failed to boot.

i guess i have to change something in my procfile or gunicorn settings

[novel stream]

is this locally or in heroku?

For things like that we would need to take a look at those files

[austere isle]

in this in the project1 > home > templates > home > index.html

[hollow dragon]

i want to deploy it to heroku but i was trying to run it locally

maybe i should try to do it for heroku?

[novel stream]

@austere isle can you actually send what's in the beginning of this file? The BASE_DIR usually will be there

[novel stream]

it probably would fail there as well

[austere isle]

ok

[novel stream]

for running locally your docker setup shouldn't depend on the procfile, which is a specific file for heroku

[novel stream]

OK so now try the following: in the TEMPLATES you will see a key called DIRS where its value for now is an empty list. Try putting there the following:

"DIRS": [BASE_DIR.join("templates")],

it will do so that Django will look for templates inside your apps

[hollow dragon]

would you mind helping me if I share my screen? it'd be easier, i'd be really glad

its a flask app btw

[novel stream]

I'm not experienced with Flask but I can try

[novel stream]

don't mind at all

I still have some time until start working 🙂

[hollow dragon]

thank you!

[austere isle]

now i got this error

[novel stream]

how is it your TEMPLATES now?

[austere isle]

\

[novel stream]

I'm sorry, let's try this here instead: 'DIRS':[os.path.join(BASE_DIR,'templates')]

[austere isle]

ok not a problem

[austere isle]

now it worked thanks a lot 😇

[novel stream]

Nice!

[hollow dragon]

Gonna try this : https://medium.com/featurepreneur/how-to-deploy-docker-container-on-heroku-part-2-eaaaf1027f0b

Hope it works 💀

[novel stream]

the only part you should be careful about is to not use sudo to run the docker/docker-compose commands

[hollow dragon]

Because of the WSL?

[novel stream]

but it seems to be a nice blogpost
