[graceful flax]

Using django and postresql

Could anyone here share their experience with Django Channels and android especially

On how to go about it, thanks! There isn't much info online on channels with android needed some guidance

[versed python]

Django channels is meant to be run on your backend server. There's noting android specific about it.

Websockets may be more like what you are looking for even though they are not really android specific as well.

[graceful flax]

Yes, so I connect a websocket

Yea, I can setup the backend, wanted to know how I'd connect them

[versed python]

I don't have any experience with android development but you should probably look up how to use websockets in android applications.

Don't mix up your backend and frontend, they will only be communicating, they are not interdependent.

[graceful flax]

Okay yes, thanks!

[native tide]

okok my bad 😅

[toxic forge]

<@&267628507062992896> I have one question recently i have developed one blogging website using Django and made open-source the complete development.
Can i share the walkthrough video/github repository link here if it's allowed?

Please let me know.

[river raven]

Please DM @hexed spoke with the details of your project

[native tide]

Can you make a forum with just purely HTML and CSS?

[calm plume]

Probably not. You would need something like js to make it reactive and you'd need a backend too

[native tide]

or do you need something like JavaScript

oh

can you use java for web devlopment

instead of js

[calm plume]

No, java is not a web development language

[opaque rivet]

sure. It's nothing special, but I actually don't know the use of containerizing the React frontend. If you have seperate containers, how will the server return HTML pages to then be hydrated?

iirc django needs access to the bundled .js files created by say create-react-app or next.js to hydrate those pages too. So running them in seperate containers will be hard if they do not have access to eachother's files.

[calm plume]

Pretty sure dockerizing is just good because with a simple docker compose up, your program can run

Well, assuming you're using docker compose

[opaque rivet]

yeah, I just don't see the point of having your frontend and your backend in different containers... Let's say that your backend had the filestructure:

/frontend
/app_1
/app_2

In your dockerfile (for your backend) you'd copy all of the files of this project into your container:

COPY . .

So then your server can serve your frontend pages. But what is the point of running the frontend in a seperate container, I probably am missing something?

[calm plume]

I'm not sure of a real reason, but here's my take on it. Say someone wants to just work on the frontend, they could do that without launching the backend. Same thing with the backend.

[vivid stag]

This is my entrypoint.sh for a docker based container. It runs everytime docker-compose is started so even the alembic migrations run everytime even if there is no change in the Schema. Is there any way to automate it by making revisions run only when there is a change and ignore the statement otherwise ?

pip install requests
alembic revision --autogenerate
alembic upgrade head
uvicorn app.server:app --reload --host 0.0.0.0 --port 5000

[surreal portal]

Do i really have to use alembic to initialize a table in a database?

[inland oak]

yes, if you wish your project being easy developed later.

migrations stored in your repository as code changes help really much

yes you can as alternative being creating your databases with raw SQL

but you will hurt your own project with it

[surreal portal]

Because i'm using FastAPI and I really want a table to be initialized

Like, whenever I'm starting my API, I'd like to have a pythonic equivalent of CREATE TABLE IF NOT EXISTS user

[inland oak]

use alembic or its alternative. It would be a great win for you

as another way you can use cursor to run CREATE TABLE IF NOT EXISTS user directly, but I highly don't recommend it

it complicates not just development, you ruin for yourself organizing easy testing too

although testing is part of development, so I should not separate those two words

[surreal portal]

Yeah because i'm pretty much a newbie in migrations. I still need to understand how alembic works

I remember a friend trying to initialize a database with a SQL schema using sqlite3 and it's far from being the most optimal solution

[inland oak]

that's why I love Django webframework

you have already basically setup Alembic and SQLalchemy

they are tuned perfectly for you

(or at least their alternative)

just few settings to switch in order to change sqlite to postgres

[surreal portal]

By the way, for a production database, would you rather use MySQL or PostGreSQL?

[calm plume]

Personally, I would go with PostgreSQL.

[inland oak]

me too

PostgreSQL is open source with free license

it is more preferable to invest your skills into it

[quick cargo]

Postgres is a solid choice

If you're forced to use MySQL you should use MariaDB instead on that note as well

[surreal portal]

Last time i've used MySQL was as a Docker container for a Flask app. Maybe I should use Postgres instead

[north aurora]

Hello Everyone!
I'm trying to create a new user profile whenever a new user is created, with the help of django signals. But its not working as expected. Can anyone tell me why?
Here's my models.py file.

Here's my signals.py file:

And here's my apps.py file:

'm getting this error when I creates a new user and try to open the new user's profile.

Can anyone tell me what should I do now?

[calm plume]

Can you share your css for the box?

Ah, idk how to style Flask forms. Sorry

But if you do know how to style them, it should be as simple as giving them a width and height

[north aurora]

Can anyone help me in this?

[surreal portal]

BTW can we make microservices with Django?

Let's say i want to use Django as a backend service

And my frontend is something like React or Next.JS

Can I use Django without templating?

[inland oak]

Surely

this is whole branch of Django exactly for that

https://www.django-rest-framework.org/

[inland oak]

exactly how it is used ;b

[surreal portal]

Nice

Maybe I should've used Django instead of FastAPI in case my app grows

[inland oak]

btw, FastAPI is technically more recommended, but I would still recommend Django for a less skilled developers
in my opinion Django is more forgiving to developer skills.

Fast API requires ability to set up at least database from scratch, which is twice harder for real project. And database is usually most important part.
Much more room to make mistakes

I think Fast API is good choice after you developed at least several applications, and already experienced python web dev

[calm plume]

They do different things, unless you're referring to DRF

[inland oak]

DRF, link above

[calm plume]

Ah, got it

[quasi relic]

for form.email.label you dont need parentheses and you can you class=“” in form.email() -> form.email(class=“email-input”) like this

[surreal portal]

Setting up database has been a pain when I was working on Flask

[inland oak]

same, same

I started from Flask too ;b

then tried my hand in Quart

and then I made very lucky stumble with Django

thinking to try FastAPI one day, may be at the next job

[surreal portal]

My friends told me it was easier to set up a db in Django than with Flask. main reason why they made us work with Flask is for understanding how webdev works on a fundamental level

[inland oak]

yeah

I told someone yesterday something like

Learn with Flask
Build with Django

Although with recent Flask upgrade

Flask can become more sweet

[north aurora]

Help needed in this!

[surreal portal]

Does Flask 2.0 support ASGI?

[inland oak]

yup

it should

[surreal portal]

Since FastAPI is built on Starlette I have an easier time than with Flask

[inland oak]

at least Flask 2.0 claims

Support async views, error handlers, before and after request, and teardown functions. #3412

[surreal portal]

Might be interesting though I'm afraid all the extensions might break.

Especially Flask RESTful

[inland oak]

yeah, same thinking

that's why I would choose FastAPI for real project

Flask 2.0 is too much new)

[surreal portal]

Yeah i'm keeping Flask 2.0 for experimentation

[quick cargo]

fastapi will generally be more performant as well

not that it matter much

but for rest apis and stuff like that fastapi is king

[surreal portal]

Yeah because right now I'm trying to use it for user authentication

[inland oak]

would it be great for GraphQL as well?

[quick cargo]

can be yes

Its a very solid framework

[inland oak]

nice

[surreal portal]

I'm trying to use FastAPI as a backend for requests and session handling

Can REST APIs use authentication or should I use another backend component

[quick cargo]

I mean anything can use authentication

[inland oak]

pretty much liking roadmap of backend skills

useful to get answers like that quickly

[inland oak]

flask mega tutorial teaches to use JWT

hmm, for now hehe I use it, until I would learn alternatives at keast ;b

JWT is nice for seassion handling

[surreal portal]

That's good to hear. because I can always use that: https://testdriven.io/blog/fastapi-jwt-auth/

[inland oak]

nice

definitely using FastAPI as next framework ;b

when I would finish taking my time with Django though

[mild zodiac]

Hey guys, hope you are all well.
I would like to decode and display a tiff image in the browser using javascript.
Non of these seems to work: https://github.com/seikichi/tiff.js and https://github.com/GPHemsley/tiff-js

any help is appreciated

[quasi relic]

it is the same way when you make a class attribute for html elements

and then you call it in css file

[surreal portal]

Also this is going to sound crazy but can you host a backend on Github pages?

[calm plume]

No, I don't think so.

[coarse haven]

static only

[inland oak]

Btw, what stops from deploying frontend to github pages 😉

like react ;b

it should be possible in theory

[coarse haven]

you can

[fresh sky]

Hey 👋 Is there anyway to avoid the page refresh every time i send the text values from the form

app = Flask(__name__)

@app.route('/')
def index():
    return render_template(r'index.html')

@app.route('/', methods=['POST'])
def my_form_post():
    text = request.form['text']
    processed_text = text.upper()
    return index()

[surreal portal]

According to create-react-app you can

[opaque rivet]

what's the difference between tokens and jwt?

[surreal portal]

i'm trying to build my portfolio with React. It's overkill but at least it shows I can manipulate a demanded framework on the market

[coarse haven]

jwt are json web tokens

theres other types

anyone could make their own token type and use it

but jwt are what we all use

[inland oak]

the thing is... you can have a whole dictionary of data (encoded to JSON), which you transform to token with JWT
So I guess Token is part of JWT usage.

we are usually encoding user ID in database / his email into this JSON, in order to verify/identify him after getting the token and decoding it back into dictionary

[opaque rivet]

I heard JWTs are just meant for short-lived requests and something more persistent like token cookies are preferred for authentication

[inland oak]

yeah, you can encode time of expiration into generated token by JWT

[coarse haven]

you can put the jwt into the cookie

[inland oak]

a time of expiration which will prevent decoding it back ;b, once time is out

[opaque rivet]

smart, so jwt's are just normal tokens but JSON, so they can have different parameters

[coarse haven]

if someone says tokens, they 99.99% of the time mean json web tokens

theres literally no other 'token' that people talk about

[inland oak]

at least they are JSON when they are decoded.

when encoded they look like one string of mess as usual

[opaque rivet]

mhm

https://django-rest-framework-simplejwt.readthedocs.io/en/latest/

guess i'll use this then

[dusk rose]

Hello, my question is about Django (the webserver) Models. Is it possible to create a model with a choice list, bur if i send an other string to it it accepts it and expand the choices?

[untold cave]

Hello, I'm new here.. Does anyone know about FLask?

[dusk rose]

What do you want to know?

[untold cave]

Actually I'm creating an app using flask and getting some error which I'm unable to resolve it

No module name “flask_mysql”

I've installed the lib and env

[dusk rose]

install and import it

[untold cave]

I dont understand where I'm doing it wrong

[dusk rose]

with pip3?

[untold cave]

pip

yes

[dusk rose]

using python3?

[noble spoke]

Can you show us code

Or well, your terminal i guess

[untold cave]

yeah python 3.7

sure

[noble spoke]

Are you using a venv?

[untold cave]

yes ive created an env

which voice chat shoulod i join?

[noble spoke]

Did you actuvate and install deps in it?

[untold cave]

yeah i did

i've also installed sql

and activated the scripts

[dusk rose]

show us some screenshots

[untold cave]

okay

from flask import Flask
from flask_mysql import MySQL

Traceback (most recent call last):
File "App.py", line 1, in <module>
from flask_mysqldb import MySQL
ModuleNotFoundError: No module named 'flask_mysqldb'

This is the error

[dusk rose]

show the pip installed list

please

[untold cave]

ok wait

[dusk rose]

pip3 list

[dusk rose]

That is not the output from the env

that ist actually your normal python. You shoul activate the env first

[noble spoke]

The package is flask_mysql

Not flask_mysqldb

[untold cave]

okay let me install this one

[noble spoke]

Are you using pycharm?

[untold cave]

PIplist of flask

[noble spoke]

Are you using pycharm my guy

[untold cave]

yeah i am

[noble spoke]

Use pycharm's integrated terminal

[dusk rose]

do it the easy way in the settings

[noble spoke]

It should have rhe venv activated

You arent using the venv in those screenshots

[dusk rose]

no he dont

[untold cave]

Should I create the env. then install flask. then write the code?

in a single folder?

I'm a she 😛

[dusk rose]

im sorry

[noble spoke]

You make the venv
You activate it
You install your deps
You run the program

[dusk rose]

should we help you in a screen share with voice chat?

[untold cave]

yes please

[dusk rose]

Voice Chat 1

[untold cave]

okay

[dusk rose]

we are muted in this channels

@untold cave

[untold cave]

yeah why?

[noble spoke]

This isnt something that needs voice tbh

Do you have a requirements.txt?

[untold cave]

I would have to check

I dont have permission to unmute

[noble spoke]

#voice-verification

Ok the steps rougly are

py -m venv venv
venv\\Scripts\\activate
pip install flask flask_mysql

And then you run the app

From the terminal btw

[untold cave]

Let me try that

[noble spoke]

If pycharm already made a venv for you skip to step 2

[inland oak]

boop #voice-verification

hmm, not working the link

[calm plume]

If you can't see that channel, it won't link

[noble spoke]

If youre verified you wont see the channel

And you are

[inland oak]

All righty, lets go sneaky
erase space in <# 764802555427029012> to form the link ;b

[noble spoke]

They wont be able to verify, they only have 40 messages here

Hello, im getting an error in my django blog web app. When i click on "New Post" to create a post for user, it gives me this error:

on the third line is the post create url path

This the layout of the web app

any help would be very nice

[wicked hare]

I'd suggest you first add a space after the single quotes
From the code it seems that the URL isn't resolving properly on the front-end. Have you namespaced the URLs?

[dusk rose]

Can someone help me with that?

[tender island]

path('post/<new>/', PostCreateView.as_view(), name='post-create'),

here is the url on the views.py

[wicked hare]

Seems like it's okay. The problem is on the html

Kindly dm

[obsidian rose]

Hey, I'm watching a django course and coding it along, and this fragment took my attention - why does it use slashes that way?
Usually it's a division operator, but I assume it just adds a slash to the newly created url - but why does it even work?

[languid raptor]

looks like magic of Pathlib https://docs.python.org/3/library/pathlib.html?highlight=path#module-pathlib

[late gale]

hello mind if i ask what's better for web for data science matplotlib or chartsJs

[obsidian rose]

Oh, I see
Thank you

[languid raptor]

I need something to act as a proxy between Linux Python script and KVM guest instance of Windows. I've created a few Django projects so I'm familiar with the basic REST CRUD, but never had to make an API before.

Simple task. Make a request comprising two parameters: connection string, ie. r'DSN=qremote_dsn;IPAddress=192.168.0.50;Port=4500;RemoteDSN=login_dsn;OpenMode=F;OLE DB Services=-2;' and SQL-syntax query string. ie. SELECT name FROM users. After query executes, I will get back a JSON-like dictionary, or other messages from pyodbc.

Looking at FastAPI I feel this is overkill. Can I use Gunicorn directly in some way? Other ideas?

[dense phoenix]

How do I have a custom url for flask?

[lusty solar]

Looking for someone to help me with web design. Take around 1 till 2 hours priv.

[primal sluice]

FastAPI is pretty lightweight I don't get how Django is not an overkill but FastAPI is

[languid raptor]

Overkill for what I need. I'm not adding an API to a resource, but using an API as a bridge between Python script and script in KVM guest

which itself has the ODBC resource

I'm just saying I don't need all the normal CRUD operations you get form REST framework, which is all the stuff that FastAPI is making easy

[opaque rivet]

Maybe use Starlette (what fastAPI is built upon?)

[languid raptor]

Does the idea of making an "API" to bridge the gap between python script running in Linux to a KVM guest running Windows so I can get to the Windows ODBC data sources sound like it is best solved by an 'API'?
If one-line description is unclear to the problem I am trying to work around the background is here: https://unix.stackexchange.com/q/647069/9494

It has a picture, too 🙂

[surreal portal]

Streamlit for small widget apps. For something more personalized they recommend Dash with Plotly. Although it’s possible to use Python as a backend for the data, then use something like D3 to publish on a frontend

[lusty solar]

Anyone who knows how to use Codepen.io ?

[soft tangle]

Hey
I want to build a website wich can stream audio from client to server and into a „virtual Microphone“ and then i need to stream audio back to the client..

[languid raptor]

Thanks for Starlette. That's a good pivot. I've been reading the docs for the past 30 minutes and going to read some more, too.

[opaque rivet]

sure thing. also, I think an API would be the best option. I may be wrong here but you could probably dockerise your linux service and run it on windows (iirc linux docker images work on windows as windows has a linux kernel - something like that) and they'd be able to communicate via http. But an API would probably be the easiest option, and starlette looks lightweight

[languid raptor]

"API would be the best option" Its the only suggestion I've received (so you're in good company). Well, the first suggestion was to create the virtual Windows system inside Linux. Haha. So either direction I still have this same bottleneck, and the answer so far is an "API". Funny, the first time I asked this question on SO, I thought I needed to use Requests to create the "API". I'm learning!

[surreal portal]

It’s exclusively HTML - CSS - JS though

[lusty solar]

I have an issue tho

Soo like my picture is next to my text with the link on

How do I get my picture above --

[jade lark]

If you're directly talking between two machines and do not want to possibly setup a server (depending on how you'd like to structure the program) you can also look at sockets.

[languid raptor]

Is there a particular Python amazing magical package which makes sockets painless and all that jazz?

that comes to mind?

[jade lark]

I don't have enough experience with it to recommend anything sadly.

You can also always look at SSH (depending on your use case there again)

Knowing what you're trying to accomplish could help me possibly recommend something else.

[languid raptor]

Here it is with a drawing...https://unix.stackexchange.com/q/647069/9494

[jade lark]

Already looking at it 😛

[languid raptor]

Originally I was doing Python script in Windows from (A) to the ODBC data source

Once I moved the script to (B), I learned after this post that PyODBC can't make the leap

So right now API, or possibly Sockets go into (???) and would talk on route (C) to (B)

[jade lark]

Either of those options are fine there is no right or wrong answer. It's whatever you're comfortable and okay with.

[languid raptor]

Certainly. It

's really is a set it and forget it. So whatever turns out to be the least maintenance and the easiest and smallest to run in the KVM guest instance of Windows will be the winner

[jade lark]

If you're running an API you will most likely need to do it on every single server as it would need to almost be like a microservice setup.

With each being able to receive requests and perform the required action after.

with sockets you would have the clients and server. Which would probably be easier to manage.

[languid raptor]

The project is an Intranet site with a bunch of Python scripts deployed through Django. Only one server right now (^_^)

I will have to investigate the Sockets option. It's the first I've heard it mentioned, so I'm grateful to you for suggesting it. That's really why I brought the question here to Discord. To poll for options so I can learn what I don't know. I'm sure once I start the research I'll recognize what you say makes it easier to manage.

[jade lark]

This is a very basic article: https://shakeelosmani.wordpress.com/2015/04/13/python-3-socket-programming-example/

If you're already running a Django server for it then you might not want to touch sockets as integrating can be a bit harder.

Is a client requesting something on the django site that will start a chain of events on the backend?

[prisma ferry]

so im building a website and i wanna transfer info from my back end to my front end. anyone knows what i can do?

im using flask

[languid raptor]

I currently have a handful of Click CLI scripts. This was great for a start, but there are limitations.

I'm reading the Socket tutorial and found what I've been reading for several hours (edit: on FastAPI and Starlette) trying to find:

"Then we print the clients address and create another variable data which is receiving data from connection and we have to decode it, this step is necessary for Python 3 as normal string with str won’t pass through socket..."

The fact this is mentioned--and in bold no less--gives me the idea I'm on the right track. haha

Just out of the box testing, all of my connection strings (for PyODBC and SQL) were borked.

"If you're already running a Django server for it then you might not want to touch sockets as integrating can be a bit harder."

I take this to mean if I was trying to integrate my script and socket call through django? Otherwise, can the coexist? The Python scripts are run from inside View functions, but AFAICT they run just like normal python scripts.

[jade lark]

Meaning you're running them as a subprocess that is detached? It shouldn't be blocking the event loop.

If you're calling a function that will open up a socket/connection you don't want to do that directly with Django where it sits and waits for the connection to close.

[languid raptor]

It's blocking the view function

[jade lark]

Yeah, don't want to do that then.

[languid raptor]

don't cross the streams, huh?

[jade lark]

It wouldn't work well is all. Think of if you had that task taking like 5 minutes.

That thread/worker would be blocked that whole time.

[languid raptor]

Oh! You mean blocking because it ties up the server. No the scripts run in < 30s. Otherwise I'm working to figure out Celery for overnight. Block all it wants

[jade lark]

Will it always run in under 30s?

Even in the future

[languid raptor]

Well. Its a work in progress. I suppose you could make a request that would be so large as to jam up the whole server. And I'd love to hear why that was necessary from my colleagues.

[opaque rivet]

you can get websockets working with django using django channels, but's there's a bit of overhead moving from the default wsgi server to the asgi server - it looks much easier in starlette or fastAPI

[jade lark]

Don't touch Django channels. Don't over complicate this. That would really screw with his current django instance w/ middleware and all

[languid raptor]

Django is just the front end replacement for CLI

[opaque rivet]

could you elaborate?

[languid raptor]

It supports the scripts, which are really just ported over, and right now what they return is ..

[jade lark]

Okay, well. I wouldn't trust them on it as stuff always happens. If you're deployed with nginx or something your requests will also timeout after 30 seconds (unless configured for nginx and the workers)

In that case I would use celery (it should only take about 20min to integrate). Then you can fire off a task and have it return right after.

[jade lark]

async_to_sync/sync_to_async You have to switch threads constantly. It would effect the whole server for any other functionality running through Django.

[languid raptor]

files saved to server. Then I put those file references into the model form so I can manage the files through Django.

It also returns messages which are then put into the Django messages GUI.

[jade lark]

That's fine. You can create an endpoint that fetches the current status of the celery task. Use JS to keep sending a request every X amount of seconds.

Once the task is completed then you can return the response from the task. You can also use Django models with Celery.

[languid raptor]

Yes. This is the dream. First I was thinking Celery Cron jobs to run overnight. What I know about JS you can stick in your eye and still see good, so that level of front end is @FUTURE

[jade lark]

It's not too bad

you can use fetch or axios

If you're wanting cron jobs too then celery would work perfectly.

[opaque rivet]

ah yeah, there's performance hits when mixing async and sync, when switching to an ASGI server the middleware (that ships with Django) is still sync, right?

[jade lark]

That majority of it, yeah. The ORM still isn't async either which sucks. I really need Django to be fully async 😬 There is a lot of gotchas with it atm

[quick cargo]

That likely wont be for a whileeeeeee

Django is so massive it's incredibly hard to rewrite

[jade lark]

I know 🥲

[quick cargo]

The amount of work it took to get Channels working was more than what most applications even come close to in terms of design

[languid raptor]

All the celery packages and databases were installed. This was one of my early requirements, but then the projects I was porting over were changed in priority and those tasks were back burner.

Just to be clear about the Sockets issues:

• sockets which are blocking in a Django loop (like view function) would be problematic in all the normal ways of having Django tied up waiting for the script to return.
• other issues if I try to integrate sockets into Django (like using Djongo for MongoDB which can be used instead of PostGRES)

[prisma ferry]

so im building a website and i wanna transfer info from my back end to my front end. anyone knows what i can do?

[jade lark]

Correct. There could still be problems with Celery (I haven't done it before). It should be fine, but I cannot guarantee it.

Not sure I understand the issue with MongoDB?

[languid raptor]

You should learn a Python web development framework which will include a system for templating your HTML

[prisma ferry]

im using flask currently

but i wanna create a login and when you login, the back end will fetch some info from a db and display it onto the website

so its not gonna be the same for everyone

[languid raptor]

No issue. It's meant as an analogy. My project uses Mongo, but I don't integrate it into Django. Same as @opaque rivet was mentioning websockets:

you can get websockets working with django using django channels, but's there's a bit of overhead moving from the default wsgi server to the asgi server

[prisma ferry]

would i have to use React or something of that sort?

[languid raptor]

I was just making sure I can use sockets without integrating with Django or having to deal with that

[jade lark]

No, you don't need to.

[opaque rivet]

so, if you have synchronous middleware - why does that give you a performance hit? wouldn't it just be "blocking" until the request reaches the view - so no slower than the usual wsgi server?

[prisma ferry]

oh

[jade lark]

Because it would have to switch between async to sync and then most likely back again.
It really depends on what you're doing in your application.

[prisma ferry]

can you link me to a tutorial or a guide in which i can follow along or learn from?

[opaque rivet]

so switching from sync -> async (vise verca), how does that occur do you know?

[jade lark]

I don't know it all off the top of my head tbh. But the docs for it explain it quite well: https://docs.djangoproject.com/en/3.2/topics/async/

[languid raptor]

I like Miguel Greenberg's Flask tuts https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

[prisma ferry]

oh ty

[opaque rivet]

alright thanks. i really want to learn about wsgi/asgi and their differences. if you guys have any good resources please let me know 🙂 i think fastapi is my next venture

[jade lark]

What's your goal? To get hired or?

[languid raptor]

i think fastapi is my next venture

You can have it! haha I'm using Sockets or Starlette

[jade lark]

I highly recommend Corey Schafer: https://www.youtube.com/watch?v=MwZwr5Tvyxo&list=PL-osiE80TeTs4UjLw5MM6OjgkjFeUxCYH

[prisma ferry]

thank you guys so much

[opaque rivet]

yes, in the long run

so I guess django would be the best option generally, but I'm only using it as an API and that's about it

[jade lark]

Learn Django then tbh. Django as an API with DRF (django rest framework) is phenomenal

One thing I am waiting on is SQLAlchemy to be out of beta for async. Or else you're going to still have the same kind of issues with FastAPI as with Django. (To my knowledge anyways). Tortoise ORM is not well supported yet nor is it production ready

[opaque rivet]

yeah currently using that, with channels + celery. maybe I'll give a deeper read into wsgi/asgi differences before I make a decision

for employability i should've probably chose express.js or spring boot tbh

[jade lark]

Should be fine with it as long as you're using a task queue and Celery

[jade lark]

There is a lot of jobs with Django as well. JS you can always learn to compliment with Python.

Learn a frontend framework (highly recommend React, even though Vue is easier for a beginner).

[opaque rivet]

yes true, I already compliment it a good chunk with react. I decided to stick with python backends for data science / ML interests

[jade lark]

You will always need a way to present that data.

[languid raptor]

That discussion was started when I came onto Discord this afternoon: #web-development message

Streamlit for small widget apps. For something more personalized they recommend Dash with Plotly. Although it’s possible to use Python as a backend for the data, then use something like D3 to publish on a frontend

For my part I'm just hoping Bootstrap will give me most of what I want

[opaque rivet]

man D3 was a pain for me

I just used react-apexcharts and it worked decent

[jade lark]

It should. Once you get to a certain point you might want to spend time learning more web technologies

It's how I started

[languid raptor]

For me I started with the laundry list of hot things to learn, but I never was able to convert that. Now its all about organic. I learn it when I need it. Borrow it if it's not important, and learn it when out of the box isn't sufficient. Which happens really quickly with front end. Like I need to take one of my current project forms and in the CLI you can just keep adding parameters, but forms? uuug.

Thats the ZEN of weekend programmer learning to Automate the Boring Stuff. ahah

Now I've been trying to finish something so I can quit for the night and this discussion has been to fantastic for me to step away. But now I've got to finish. Most excellent discussion. Tx peeps.

bye for now

[jade lark]

No worries! Best of luck hope you get it figured out.

Someone can help with django? I'm a beginner in django

I need to consume api for a homework

[prisma ferry]

cant help u there mate

i only knoq flask

[vestal hound]

just post your question

don't ask to ask

[vestal hound]

I favour Angular myself

React is very popular though

How do I center my text, Its in the center. But I want it in the middle

[limpid cave]

Hey guys I seem to bet getting this error, and I can't figure out how to fix it

Here's my code

I have tried using redirect(request.referrer) and the same error still occurs

all my folder are in the correct location

has any1 encountered this error?

[outer apex]

Like horizontal or vertical centering?

[outer apex]

what is the directory structure of your app? are the templates in the templates directory? are you passing a custom templates path when instantiating your Flask app? Are you sure you named your file correctly - all the capitalisation etc.?

[limpid cave]

This is my dictionary view

the backend file is the file for writing the flask code]

[outer apex]

what's in the templates directory? can you share how you're instantiating the Flask instance?

[limpid cave]

It's working now. But it wasn't working for the entire night and when I used redirect and idk why

[outer apex]

right, if you hit /create with a GET request, it's gonna reach render_template(request.referrer). Whatever request.referrer evaluates to, it'll try to find a template with that value as a file name. Obviously you don't have something like http://localhost:5000/ as a file name.

[limpid cave]

I was just trying out different solutions

[outer apex]

👍

[limpid cave]

But I didn't know that so I'll keep that in mind. Much appreciated

[opaque rivet]

since JWT tokens ship with a secret, we can say that they are untamperable.

Say we had a service for adding balance. Instead of sending data in the POST request body (where someone can intercept the request and change the balance they give themselves), what if I generate JWT tokens with this information? It sounds like a good idea to me.

^ People tell me that JWTs are meant to be short-lived and shouldn't be persisted for long. Why is that?

[cosmic swallow]

I don't know where to ask this so here is good as any
Does anybody knows package which can translate WSLD into python code (class preferably) and has realse sooner then 10 years ago?

[worn mural]

Because you cant invalidate a JWT. Let's supose someone hacked your account and had access to your JWT and this JWT had a 1 week life time, even if you changed your password they would be able to perform actions using your account thru this token. It isn't safe.

[worn mural]

You could generate a token with this information, but that is the beauty of JWT, they are signed, so unless they had access to your private key they wound be able to forge a valid signature.

So you need to verify if the JWT signature is valid and then proceed.

[opaque rivet]

yeah, and am I correct in saying that JWTs are stateless (so no db information is stored) so if the JWTs are not short-lived, then we will have users authorized when they shouldn't be (e.g. if they are banned)

makes sense.

[worn mural]

Exactly

[opaque rivet]

hmm yeah. I don't think I'll be able to JWT encode my POST data, because then I'll have to make a seperate request to my server to return the secret key, and that can be intercepted.

[worn mural]

This isn't a good practice

your post data should be sent tru the request

with the JWT

The jwt its only used to authentification

If you want to display the balance of a player for example

You should send a request to ur backend with the JWT and the backend will return the balance

If the JWT is valid of course

In my personal app I use refresh tokens with access token

The access tokens are valid for 5 minutes

And are JWT's

that are issued by my authorization server

And they can be generated from a refresh token

With the user logout for example I just revoke the refreshtoken

and they cant generate new tokens

After 5 minutes

From refresh token

This is the flow

that I follow

[opaque rivet]

Sounds good. What library do you use for them?

I'm just trying to think of ways to prevent people from intercepting http requests & changing their payload.

[surreal portal]

I love FastAPI guys. It's so smooth and creating a JWT system didn't look too hard

[worn mural]

I love FastAPI too

[drifting radish]

hello

[opaque rivet]

I'm learning a bit of FastAPI today, hence the JWT talk 🙂

[surreal portal]

Wish i could custom the username field in OAuth forms

[drifting radish]

Is it possible to make such a popcat page?

[surreal portal]

Haha same here. Especially for authentication

[worn mural]

Why so ?

[drifting radish]

clicker

[surreal portal]

I want to use the mail as an authenticator instead of a username when I want to test on the Swagger UI

[drifting radish]

ohdady gb

[surreal portal]

But the doc said "no problem you can customize the field in your frontend"

[worn mural]

Ohh

[worn mural]

JWT

People will always be able to change the payload

If this is a problem for you

you need to change your inside architecture

Or validade tru ur backend

[opaque rivet]

surely I'd imagine a lot of websites are prone to just changing the payload

if I'm adding a balance on a website, use Burpsuite to intercept the request and change balance from 5 to 500, then pay for 5, the server might have inadequate checks

so yeah I guess I can just use conditionals and extra checks to prevent that

[worn mural]

A local Tinder for grad students here in São Paulo(Brazil) has a premium version that unlocks more likes

I saw that they didn't verify if the user was indeed a premium member

They did everything thru the payload request

With a param called "unlimited" = True

I intercepted and made every request sent this parameter

[opaque rivet]

haha, that's great 😂

[worn mural]

and even if I didn't pay

[opaque rivet]

did you use Burpsuite for this?

[worn mural]

Noo

I used ProxyCharles

Its pretty much the same thing

[worn mural]

I was able to do unlimited likes

[opaque rivet]

that's great 😂, I'll have to try the same thing haha

[worn mural]

hahahaha

I make tons of money

Because they didn't launch the premium version yet

and people were hungry for this feature

So I created a custom client that send this parameter tru the request

and sold for other people hahaha

[opaque rivet]

😂 You're genius

[surreal portal]

A bit OT-Python related but is there an effective way a react client can use JWTs?

[worn mural]

Sure

To make requests

to the user information

[surreal portal]

Is there any library that can use effectively JWTs to access protected routes?

[fading mason]

whats a good udemy/linkedin course for learning django?

[opaque rivet]

You could most likely make a middleware for this

[worn mural]

Ohh Idk of any library

[surreal portal]

CS50: Web Dev on EdX

[fading mason]

oh wow

[worn mural]

this is how it works @opaque rivet hahahaa

[surreal portal]

Best way to make use of webdev when you're a total beginner is trying on Flask, learning how routes work and making HTML templates

[opaque rivet]

😂 😂

bloody smart guy

[surreal portal]

Then you can move on to data persistence with databases and learn how RDB works, how SQL works and how ORM works

Next step is APIs, microservices and REST

[fading mason]

I know how DBs work, and I know general web dev stuff. Just looking to learn Django in-depth

mainly cuz its huge and has a ton of features

[worn mural]

@opaque rivet and this is the JWT they use to authentification

As you can see

they don't have any expiration time

[surreal portal]

is this graphQL?

[worn mural]

No this is just jwt.io

I can decode the jwt

[worn mural]

So if I ever had access to the admin access token I would have unlimited access

[opaque rivet]

so you have another server returning the refresh tokens?

and I guess each refresh token has to be specific to each JWT? So once the refresh token expires, the JWTs are invalid and can't request new ones

[opaque rivet]

also, what do you think about encrypting the JWT tokens themselves? That way outsiders can't see its contents?

[nimble dawn]

Is figma good for web development

[calm plume]

It's great for setting up your designs

[nimble dawn]

Like if I take codes for some elements

copy and paste, not the whole website only for some elements in which I get stuck

[calm plume]

That's a good way to learn. But just make sure you understand the code you're copying

[worn mural]

Good Idea but not really needed

[surreal portal]

I need to sharpen my skills for front-end design for my Github pages

[worn mural]

I don't do it

[opaque rivet]

check out tailwindUI, do you use react/vue?

[surreal portal]

React and I've already heard of material-ui

Though for my portfolio I'd like to try vanilla CSS

a good component library is antd. But even better, it's tailwindUI, based off tailwindcss which is just a glorified bootstrap with some extras.

[surreal portal]

Baidu uses it I've seen

Not me. I only know flexbox and there's too much relative units to use from lmao

[native tide]

hello there

I think this is the right place to ask the question

Should someone coming from full stack js (react-js, react-native, nodejs) use flask for backend and continue to use react-js and react-native as "front-ends" or would one learn django?

[calm plume]

Go ahead and ask your question, and someone will help if they can

[native tide]

I am not sure about what should I do since js is a must for someone front end stuff but yet django features seem promising

correct me if I am wrong

:)))

[opaque rivet]

django isn't a frontend framework, so for front-end, you will have to end up learning JS

[native tide]

Oh, I mean i am really confident in my js kek

So I could easly integrate django with react-js for example?

[opaque rivet]

Yes

If you're really confident with JS then you can also go for the node.js backends, such as express

[native tide]

I mean I did use that for years, I am looking to switch for some personal reasons

and not to be toxic but from what I've seen django is better then flask for making scalable backends right(flask seems really good for prototyping)?

[opaque rivet]

Scalability really just depends on how you build your app. The main difference is that Django is batteries-included so it has lots of features out of the box (such as an ORM, etc.) while with Flask you can choose your modules and really personalize your app. Django is more popular.

and with Django it's much more easier to get going due to the amount of things already provided by Django.

[opaque rivet]

how come you wanted to move from node.js? I was thinking to move to it before deciding for FastAPI

[native tide]

So for the projects I am working on I am doing a huge amount of stuff in C,C++, lua, nodejs,x86, so i kinda decided to move to a new more general programming language

since speed isn't really an issue

anyways thx I'll look into django :))

[calm plume]

Depends on what it is

But usually, no

Then 4ms shouldn't really matter

[thorn idol]

Can I ask a css question here? :)

Nvm just saw the channel info xD

[calm plume]

[thorn idol]

So I basically tried to make a navbar with bootstrap:)

But the drop down isn't working..

[topaz widget]

Hey does anyone know why Chrome would botch a CSS transition on the first attempt but get it right every time thereafter?

[hoary brook]

Maybe you have defined the transition in something like the :hover element instead of the "main" element.

[topaz widget]

Thanks for the response, but the transition is initiated by JavaScript after clicking on an element.

[hoary brook]

Ah okay, I was just wondering since it's happened to me before as well

[topaz widget]

I tried just running the transition before the user would get to it, but it seems to have to be visible on the page.

[hoary brook]

Yeah, transitions and animations get initiated when the element becomes visible.

[topaz widget]

I gotta tell you, I'm getting pretty sick of the browsers' rendering engines. I'm probably just gonna switch entirely to WebGL for visually intensive stuff from now on.

Hi, I'm uploading a flask API to GCP at the moment, but I have never used any cloud platform before. At the moment, I have most of the application in the editor including a yaml, requirements, a venv, and all code. There are also files from a user that will be stored here. Is this the best place to store these files, or is there a better option I should be looking to after this is deployed?

[outer apex]

What's the file being used for? Is it mainly for reading, or are data getting written into it? Is it ever going to be distributed/sent?

[wooden path]

I generate the files, store it somewhere, and then it gets sent back to the user if requested

They're mainly text and audio files

[outer apex]

Gotcha. Maybe consider Cloud Storage? The API to handle files in Storage is probably pretty straightforward.

[wooden path]

ahh I will give that a try

Thanks!

If I had a pytorch model that's being deployed with the app, is it best not to move that?

[outer apex]

I'm not familiar with pytorch models. Are they relatively stable and not for distribution? If so, it's probably okay to keep it with the app.

[wooden path]

I'm honestly not too sure, I was mainly given this code and told to host it. The model is only being used by the app itself so I guess that means i'll just leave it as is

[outer apex]

Gotcha. Yeah, that's probably fine.

[wooden path]

Thanks for your help!

[last orchid]

When I start a jupyter-notebook server for instance, it gives me a token i need to use to connect to the frontend with:

How would I go about implementing something like this in an app I'm making? It runs similar to jupyter with a local server and a web frontend
I'm using Flask. I know I can basically use flask_login to do it, but bringing that in seems a bit overkill for the situation, where I just want to randomly generate a token
I'm thinking about essentially just writing my own "middleware" and comparing against a randomly generated number at startup, but I feel like there's probably some gotchas there
and I'm imagining there are packages that let me do this sort of thing cleanly and explicitly.

The server does't show any error message, but shows "Cannot receive from redis... retrying in 1 secs" sometimes.
Can anyone tell me how to fix it?
I'm using Azure Redis Cache as a message queue database.

when you using django you can add something like py {% static 'path/to/image.png' %} but if you are not using django or any other frameworks that work like that copy your image in the same directory where your html file is and do it like ```html
<img src="./image.png" />

i think you actually want to learn the app, right?

[proper mural]

no bro i just want to have the url of my picture

idk is it too hard too undrestand ? idk how to say it to be undrestanable

you want to get your image url based on this https://cdn.statically.io/img/:domain/:image so you need to see how to use this statically app or anything else it is

I usually use React with Sass or TailwindCSS for frontend, and Node.js, Django, or FastAPI for backend.

[grave needle]

Cool!

[grave needle]

I don't know how CSS preprocessors work yet...

[elder root]

sorry wrong channel

just django and react

[calm plume]

Ok

[solemn glacier]

what lol

[calm grove]

hehe

python puns

[solemn glacier]

I think the guy you replied to was talking to somebody else.

What do you mean

Run a python script with html

[calm grove]

i mean

[calm plume]

HTML and Python do very different things, you don't run one using the other. However, you can use them together.

[calm grove]

like how?

[solemn glacier]

You must first describe your intention

what is your goal

[calm plume]

You could use HTML as part of the frontend and Python for the backend

[solemn glacier]

what are you trying to do

excuse the typos, my keyboard is too slow for my fingers

[calm grove]

well i mean its not like you can do ```html
<script src='main.py'><script>

[solemn glacier]

No, it's not.

[calm plume]

Check out Flask or Django. It's make more sense then. But basically, you could use HTML as part of the frontend and Python for the backend

[solemn glacier]

in general terms

[rare ibex]

Hey, can someone help me with making my flask webhook listener work

[solemn glacier]

you can't run client side python code in a web browser by visiting a page

[rare ibex]

so i made this to listen to post requests from a platform, but it doesnt work with my local machine ip url

[calm grove]

ive heard of them. what exactly are Flask and Django

[rare ibex]

but i hosted the same code on replit and gave that url, it worked there

so how do i make my webserver public so that theplatform can send requests there

[solemn glacier]

They're back end python frameworks for web servers. I think you should first review the concept of frontend/backend or rather client/server

[solemn glacier]

You want to host a web server on your local machine?

a public facing web server?

[rare ibex]

no im actually gonna host it on my vps

[calm plume]

@calm grove I think you would benefit from reading this message: #web-development message

[rare ibex]

but rn, its just for testing

but i cant test if it doesnt work on my machine

[solemn glacier]

or you an only connect to the platform api when its hosted

not on your local?

[calm grove]

thanks i'm looking now

[rare ibex]

didnt get you

[solemn glacier]

what i mean is the problem you are facing is it that you can test when you host on your vps, but not on your local machine?

[rare ibex]

im still developing it on my local, so i'll need to change the code and stuff, but i cant really test it since it doesnt work with my url

[solemn glacier]

you can't do the post requests?

[rare ibex]

no i havent hosted it on vps

i will but not now

[solemn glacier]

Sorry I still don't have a clear undertanding of the exact problem

[rare ibex]

there's this platform called repl.it that runs python code online, so i ran my code there and gave that url

[solemn glacier]

ok

[rare ibex]

the other platform(one sending webhooks) sent the post data to my webserver which is running on repl.it

but when i local host, i get address like http://121.0.1... and when i give that, it doesnt work with it(the platform that sends webhooks doesnt work with that url)

[solemn glacier]

oh

the platform isnt local

the second platform

making the requests

?

[rare ibex]

nope

[solemn glacier]

You'll need to portforward

i dont suggest it though

[rare ibex]

its another api/website that sends pings when user purchases a product and stuff like that

[rare ibex]

whats another option?

[solemn glacier]

I wouldn't expose your local web server to the public net

er

hmm

[calm plume]

It's http://127.0.0.1 iirc

[solemn glacier]

can you move your platform making the requests to local

for testing

[rare ibex]

yes

[rare ibex]

i cant actually

[solemn glacier]

127.0.0.1 is an ip address for a local connection, without NAT. so he would use that if he broadcast to his loopback address only but the problem is

[calm grove]

@calm plume basically i'm just trying to make some kind of hangman website for a little portfolio project. just something to be able to say that i did. not very important but i want to know if i should use js for it or python. python would be easier cuz i already have a python script for hangman. how would i go about using that script to make hangman website? or is it to complicated and i should just use js

[rare ibex]

since its a public website that sends these webhooks

[solemn glacier]

A third party service on the internet can not make a request to his loopback obviously, or even his local machine unless he exposes it to the internet via portforwarding

[rare ibex]

how do i expose it to the internet?

[solemn glacier]

portforward on your router

are you in a basic nat environment?

[rare ibex]

uhh idk what that means lol

[solemn glacier]

it's not a good idea

[rare ibex]

hmm

[solemn glacier]

Do you need the post data from the third party platform

[rare ibex]

so the only other option is hosting it on my vps?

[solemn glacier]

or can you do it yourself

and send it locally

The VPS should work

[rare ibex]

ye i do

[solemn glacier]

vps*

[rare ibex]

hmm i dont rlly have access to the vps right now, so ig ill just run it on repl.it to check ifmy code works, is there any other option?

[solemn glacier]

don't use NAT

which is 100x worse than portforwarding lol

[rare ibex]

also when i host on my vps in future, i just have to give the url that it outputs when i run the flask code right?

[rare ibex]

oh ok

[solemn glacier]

you'll want to make sure you bind to the correct address

by the way

those post requests

your local machine is a web server listening for post requets? it is not sending any type of request to initiate it?

[rare ibex]

nope

oh it does work with an wrapper for google sheets

[solemn glacier]

ya, vps is your best option or generating the requests locally

is it hard to deploy a flask project? i've been thinking about learning flask more

[wooden ruin]

using libraries like gunicorn can make it easy to deploy a project

if you are using static files you will need to configure this with something like nginx or whitenoise

[azure saddle]

oh, thanks for the info!

lets say I have a python set how can I show all the items in a python set to a html list?

[wooden ruin]

you can iterate over the set and create a string based on the content of the html file, then writing that to the file itself!

however it's best to use a templating engine like the one flask/django use

[opaque rivet]

can you guys explain why you can't have websockets with WSGI? Why can't you just handle the request on a thread?

[buoyant shuttle]

Hye guys I'm having problem

My graph is not showing in chart. Js

[regal raven]

Heyo. I'm building 2 web apps in Flask and have the same problem in each on multiple environments, which tells me the problem is with me not understanding something.

I am trying to use Flask's redirect function. The line looks like return redirect(url_for("play"))

But instead of sending me to the proper location, it redirects me to http://localhost/play

Why is this? Is there some server configuration I need to do? Am I supposed to supply flask run some additional flags?

[native tide]

I'm using flask, then?

Or quarts?

[regal raven]

From what I'm reading online, it seems I need a web server like Apache or nginx or something atop my Flask app. Hopefully that will fix things?

[wooden ruin]

if you are using Flask, you should get familiar with their template syntax. it's really cool and powerful, it comes built in as well

[wooden ruin]

typically something like nginx or whitenoise are used to handle static files (css, js, etc.) personally i like using whitenoise because it's fast and easy

[regal raven]

Well, I don't see why this shouldn't be possible with the default webserver

in flask

(also i'm not just serving static files btw, i rely pretty heavily on jinja2)

[wooden ruin]

no need to worry about jinja2, that's handled with a wsgi/asgi server

[regal raven]

well, any idea about the redirects issue?
