You could use url_for

[wheat verge]

*args allows you to do is take in more arguments than the number of formal arguments that you previously defined

def myFun(*argv):
    for arg in argv:
        print (arg)

myFun('Hello', 'Welcome', 'to', 'Django')

output
Hello
Welcome
to
Django

any speed improvements can be made here?

Hey guys, I'm working on a web project based on python-django and trying to push it to heroku. but I get a rather strange error.

remote: -----> Building on the Heroku-20 stack
remote:  !     No default language could be detected for this app.```

when forcibly putting ```heroku buildpacks:set heroku/python```

it returns ```
 remote: -----> Building on the Heroku-20 stack
remote: -----> Using buildpack: heroku/python
remote: -----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/python.tgz
remote:        More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure

but since I'm making a site according to the guide, it looks rather strange.

code source: https://github.com/KoTeD0/learning-log

if someone can help me with push and build on heroku i'll be very helpful

[compact glacier]

[turbid raven]

hey guys, i am coding a small web server that can return different kickstart files according to the username passed. My current thing is, when i send something like http://ks.myserver.com/kickstart.ks?user=myname I get kickstart.ks?user=myname back as filename. which is not what i want. i just want a kickstart.ks file

i think this is called scrubbing?

i want to tell the client to save the file in the correct filename

or do something on the python server side to return the correct filename

[high breach]

Hi guys,
I have a flask app, so when I hit on routes which are not in the same file, it always throws 404 not found error:
Directory structure:

-> user
    -> __init__.py
    -> models.py
    -> routes.py
-> app.py

app.py:

from flask import Flask
app = Flask(__name__)

from user import routes

@app.route('/') # THIS ROUTE WORKS
def index():
  return '<h1>HOME</h1>'

if __name__ == '__main__':
    app.run(debug = True)

routes.py:

from app import app

@app.route('/register', methods=['GET']) # THIS DOESN'T WORK - 404 NOT FOUND ERROR
def register_user():
  return '<h1>Register a user!</h1>'

[gray lance]

so i'm guessing you're running only app.py, and so routes.py is never run, and thus that route is never registered

you need some way to make sure that routes.py is run as well; one way would be something like

-> main.py
-> app.py
-> user
    -> __init__.py
    -> models.py
    -> routes.py
```,  and the `main.py` would be something like
```py
import user.routes  # importing it runs the file and hence the routes there are registered
from app import app

app.run(debug=True)
``` and then run the main.py file instead

there are possibly other ways but i remember doing something like this once 😅

@high breach

[high breach]

yes?

[gray lance]

oh i just answered your question, figured i'd ping in case you'd miss it

[lone hedge]

question on Flask \w Jinja templates, is it possible to pass a function to a view as a variable and reference that python function in an onclick property for some button in the view? looking for the best way to do this if possible

[outer apex]

Are you hoping for the click to run this Python function? This is not going to work.

What were you hoping to do?

[lone hedge]

yes, and avoiding writing the pure JS version

[proper hinge]

The browser cannot run Python code directly. If the click handler needs to modify something on the client side, then you're going to have to write it in JS.

You can trigger a function to run in your Python backend if you set up a way to communicate between the client and server (e.g. an API)

[lone hedge]

yep, have an api

[proper hinge]

Then you need to write JS code that will make a request to your API

[lone hedge]

got you 😦

[faint ferry]

how can i make a dashbord for my discord bot

[unique shore]

use a framework and interact with your bot through an API

[native tide]

What's the best way to return an image to the user from an external url such as ibb.co in a way such that it acts like it is a local image?

Im wanting to replace a send_from_directory return to get an external image and return it in the same way

flask btw

i figured out a work around, but this would be nice to know for future projects if anyone knows ^^

[dull frigate]

Hi

What framework(s)/setup/configuration do you recommend for a project that is asynchronously and constantly reading live data, processing it and then showing it in a website? At the moment, I'm using asyncio loop that runs forever that feeds an object and asyncronously detects changes in a "communication object" and send those changes through a websocket. But I feel it is very clunky, a lot of global variables, while True loops, etc

How would you "structure it"

[inland oak]

Django Channels
Or FastAPI
Not sure which one of them

[dull frigate]

together or one or the other?

very new to this kind of development

[inland oak]

Choose only one of them

[dull frigate]

looking for orientation here

these support live 2way communication?

[inland oak]

Dunno. Never worked with web sockets.
I only know that Django channels allows to work with web sockets and had as a example how to make a chat

Django is pretty structurized out of the box

If u look for some enforced structure

FastAPI as far as I know, best async framework

So could be nice choice too

I dealt only with django before though

[dull frigate]

thanks

[agile pier]

pls help me with this..

[scenic dove]

Hello
is it possible to be a web dev without learning JS ?

im learning django rn

[small coral]

Probably not, you'll most likely want to know how to use JS frameworks such as React as a web developer

[scenic dove]

React uses only JS ?

i mean its main language like with python and django?

[inland oak]

Technically u can, since python is backend language to make Rest APIs.
But know that knowing JS is still obligatory for any Dev in web development, if the person is beyond junior level

At least basics of it

Ideally yeah, js is used to make properly frontend in react/Vue.js

Then the person becomes backend person that can pretend to know some frontend

And yes, js is the main language of Frontend languages

There are no alternatives

Only things like typescript, which is just mypy'ed(static typed) extension of javascript

If u make some normal pages in python backend, u still need to use sometimes js as addition

But usage of vanilla js is a great perversion and ugliness

If u need js in python backend, better to make static linking to vue.js, to use it for much easier js syntax.
It is possible to use vue.js inside of any backend framework

Ideally frontend is made separately though

Because then person has full access to all things with js npm package manager

[lusty smelt]

Hey everyone! I've got a help channel open but it was suggested I post here as well. I've got a pretty specific question I'm hoping for some guidance on.

I have a Flask application that uses HMAC headers for authorization. I have all the documentation for how to properly format your headers and I need to insert the info into an API page.

So I need to make a custom security scheme for my HMAC authorization. I am having trouble finding a good example to follow.

It appears Redocly doesn't support HMAC headers out of the box. Like it does for OAuth1.0 and others

I'm over in #help-chili if anyone has some assistance for me

[pearl vigil]

Anyone used Django-Signature before?

i am having trouble with authentication

[pearl vigil]

looking to get signatures on django forms

[ember adder]

In Django I have a form with a ModelChoiceField which queryset can have 1k+ entries. That would be pretty heavy performance side and I want to avoid the user to scroll a huge list. What are good alternatives?

[gleaming kernel]

Im setting up a tiny form but I cant get the "submitted" part to stay on the screen before it reloads

can I set up a timer?

or stop the page from reloading?

[jade minnow]

setTimeout?

[gleaming kernel]

ill try that

[agile pier]

as it is advised to change the secret key in django settings.py
so while changing the security key, do I need to make some other changes also somewhere?

[native tide]

It's just a key that is used in the some of the security features that if a malicious person knew it, they could invalidate the built in CSRF protection and stuff like that

if you're talking about preparing a production server, there is a lot of things to go over to really be ready to do that.

i just generate one with import secrets;secrets.token_hex(32) and stick it in there.

[agile pier]

can you please tell me those things?
like changing the key, debug=False, and..?

[agile pier]

so i dont need to make other changes related to secret key after changing it?

[native tide]

well, they are a great deal of things that you really will have to read about extensively because those things you mentioned are just getting started.

as for the key, no. You just change it and it automatically does its job as long as no one knows what it is and its sufficiently unguessable.

If you're not pushing to production or anything dont worry too much yet but eventually digital ocean has good guides

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-20-04
https://www.digitalocean.com/community/tutorials/how-to-harden-your-production-django-project
there's tons of them

[agile pier]

i also made these changes
https://stackoverflow.com/questions/65172313/how-to-get-rid-of-django-security-vulnerabilities-warning-signs-in-terminal for security

[agile pier]

thanks for this

[native tide]

thee thing to remember is dont take production lightly. There isnt a checklist to be secure. You make mistakes and its not secure. so you have to know all the things that can happen and stay read up on all of it. As long as you knw that going in, and dont think it's magic and safe, you'll learn it as you go

[agile pier]

got it, thank u

[native tide]

it helps imo when you start playing with having you own test production server to dabble a bit into penetrating testing on it. You dont have to go all in on the career of professional pen testing for clients. Just... try to break your own server.

and look up how to do it

common misconfigs etc

but run your test server pretending its a real production server and having it set up exactly like one.

[agile pier]

okay, good idea

[austere acorn]

If an API uses cursors to paginate its results, how am I supposed to send concurrent requests to fetch multiple pages ? Because in cursors each page depends on the previous one

[unkempt haven]

Hi everyone its my first time scripting a website and i need help

I run my code and it gives me a link to open it (im using flask)

but i keep on getting problem

[austere acorn]

Show us the output of your console

Also did you write any view ?

[formal gull]

how would i go about determining if my sqlite database has been updated and send that to my websocket i have working now in django?

i've read some about redis, but im not sure as most things using websockets are just chat apps and im not sure of what is exactly what i am looking for

[austere acorn]

You can use django signals instead of subscribing to events from the database itself, that's easier but not sure if it's the best way to do thing.

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

[formal gull]

from just skimming does this sound about right, when someone else submits something/updates something i attach a signal to that to tell the websocket to update?

[austere acorn]

Yeah exactly

I am sure there are ways to subscribe to events from the db itself but I don't know much about that, I think for what u need this should suffice

[formal gull]

i could of swore i read something about subscribing to db events, but i dont see why signals wouldn't work in my case for the amount of users ill have

thanks!

hi

how can I add HTML and CSS and JavaScript into flask web?

I mean whole file of HTML

[native tide]

learn how to pass a jinja2 template to the view. Then in the template, you would load in the javascript somewhere.

and css

a template is just an html file with special syntax to conditionally load the html and other types of normally static content

[lost snow]

hey guys
I am a beginner web dev
I am interested in learning more about web security and how to become the guy who protects websites from being hacked....
I have been browsing about it but can't find anything useful related to it
I want to know how to become one...
so, If anyone knows anything about this please share....

[small coral]

Things like networking, server hardening, are some important things I can think of to help you become of those people

[mint folio]

Aside from the server side configuration, it might help to understand how web applications work, if you haven’t already. Then you can look into topics like CSRF, session management, file upload vulnerabilities, SQL injection, XSS. Also frameworks and libraries have their own vulnerabilities, which you can look into as they are generally specific to the versions.

There is obviously more, but the ones listed above as well as the comment above about server security should be enough for the basics.

[wooden hemlock]

Does anyone know if there's a decent way to use flask_login and firebase? I've found documentation from a couple of years ago but I think it's deprecated by now. There's not really anything else that's clear on using the two now.

What is the easiest way of making async calls in django
With ajax or there is a native way in django
I have to make loading screen

[jade minnow]

#cybersecurity could help you with that, last time i was in there it was about php password sign-in security and how to prevent it

[inland oak]

Django has nothing for frontend except Jinja templating language

If u wish more Frontend, use frontend Frameworks.
Or at least make static linking of frontend Frameworks like vue.js into Django to enable it from inside

[inland oak]

Anyway inside Django templates u can have only frontend that u can statically link.
I think jQuery can be enabled too

[kindred carbon]

Yes I have done it in react but not in any django only site
Thanks for the help 👍👍

[inland oak]

If u use react then...

Continue using react. Use Django as rest API to react ;)

[inland oak]

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

[jade minnow]

counter {
  transition: --num 1s;
  counter-reset: num var(--num);
}
counter:hover {
  --num: 31;
}
counter::after {
  content: counter(num);
}

how can i make this count up without needing to hover over top of it? Like can i edit this with js? without needing the hover?

[inland oak]

When do u wish to trigger

On page load?

[jade minnow]

well i have a splash screen that lasts 2 seconds. 3 seconds tops because its element gets removed

i tried using settimeout and making the hover a counter.animation {}

but it didnt seem to work and my js is lacking

[inland oak]

U can trigger transition by adding class with js

Turn hover into class

And add it when to start

[jade minnow]

i did that using ```js
setTimeout(() => {
document.getElementById('counter').classList.toggle('anim'); }, 2000);

it didnt seem to work

my js is bad dont bully me

[torn timber]

It's set interval btw

[inland oak]

Vanilla js... It is awful to use in general ;)

[jade minnow]

oh.

[inland oak]

Frontend frameworks for the win

[jade minnow]

well i started using a different script

$('.counter').each(function() {
          var $this = $(this),
              countTo = $this.attr('data-count');
         
          $({ countNum: $this.text()}).animate({
            countNum: countTo
          },
        
          {
            duration: 7555,
            easing:'linear',
            step: function() {
              $this.text(Math.floor(this.countNum));
            },
            complete: function() {
              $this.text(this.countNum);
              //alert('finished');
            }
          });  
         
        });

css:

.counter {
  display: table-cell;
  margin:1.5%;
  font-size:50px;
  background-color: #0077B6;
  width:200px;
  border-radius: 50%;
  height:200px;
  vertical-align: middle;
}

html

<div class="counter" data-count="31">0</div>

output:

[inland oak]

Check svelte out of curiosity.
Although I would usually recommend only react or Vue. Js

[jade minnow]

the circle im def gonna format to the middle

[inland oak]

That is jQuery, i think

[jade minnow]

might get rid of the text

[jade minnow]

yeah i do ALOT more work with jquery

it just feels better personally

[inland oak]

jQuery is just vanilla js on steroids

[jade minnow]

thats why

[inland oak]

Frontend frameworks much better

[jade minnow]

omg im so dumb

if this works

im sorry

but like

nvm

didnt work

anyways

<h3>Now in <div class="counter" data-count="31">0</div> servers!</h3>
    <script>
      $('.counter').each(function() {
          var $this = $(this),
              countTo = $this.attr('data-count');
         
          $({ countNum: $this.text()}).animate({
            countNum: countTo
          },
        
          {
            duration: 7555,
            easing:'linear',
            step: function() {

didnt seem to work

i did alot more than i needed

let count = 0

const countUp = setInterval(() => {
  let boxCount = box.dataset.count
  if(count == boxCount) clearInterval(countUp)
  box.innerHTML = count + box.dataset.unit
  count = count + Math.floor((boxCount/31))
  if(count > boxCount) count = boxCount
}, 20)

css:

Hey folks

What approach do you use to integrate react and Django together?

1. Build a standalone react app and host it separately
2. Serve react app from Django.
   Please share your insights and why do you prefer your approach.

[inland oak]

Building standalone react app, because it is the way to microservices architecture

Better scalability with code growth

Using methods less than that makes sense only in some pervert situations with really silly restrictions

[hidden kettle]

Thanks for sharing your feedback😊

[inland oak]

U a welcome. Also as a point...
People use less than that because they don't know Infrastructure instruments

Already with docker compose it should not be an issue

[hidden kettle]

@inland oak And what mechanism do you use to build real time apps with django? Channels or some third party services like Pusher

[inland oak]

And because people don't know Auth methods

[inland oak]

Not developed stuff like that yet, but I am eyeing my choice between Django channels and FastAPI as first candidates

[hidden kettle]

You mean people serve react with Django?

How is this related to authentication? Can you please explain this to me

[frank shoal]

I serve vue with nginx

[hidden kettle]

That's what I like to do. Serve standalone with Apache or nginx

[frank shoal]

I specifically use nginx-unit because it can run my asgi app too

https://github.com/killjoy1221/nginx-fastapi-vue-docker

[hidden kettle]

That's pretty awesome. I too use nginx to serve react app.

For backend- Django I deploy it with containers on Google Cloud. I also use app engine

[jade minnow]

i have some questions about this:

should i have the text inside?
should i use just the number itself?
if i do; would people notice its the amount of servers and users with the icons i have in place?
should i use a gradient? or have a still color?
should i use animations on them? or just the static images itself?

i get alot of hate because of how this looks and im now finally going to change it. i dont want it to look like complete shit

[inland oak]

Not familiar enough with React, but people differently can serve Vue.js with django

[inland oak]

There are different ways to Auth users in order to keep them authed. In built Django methods for frontend Frameworks we can probably find in DRF.

The point is... With microservices architecture, we have multiple backends, and we Auth only in one from frontend, and to be not validating in one database?. How do we achieve it? How to create tokens for temporal URLs of email verifications and password resets, which we could create in backend, and accept in frontend?

The answer to everything is JWT.
Which is the way to keep a dictionary of key values with user info and rights, validated by your secret key.

People at the beginning not really familiar with Auth stuff to use microservices freely

With one just Django they could use inbuilt methods with minimal understanding how it works

whats the different between css and scss

[frank shoal]

scss is css with sass

scss supports pre processors and nested rules

You can also get variables via ```scss
$red: #FF0000;
body {
color: $red;
}

Do I have to manually set a httponly cookie? I'm getting it in the login POST response, but then when my flask backend tries to access it on another request, I get no access_token cookie response message

[quaint wagon]

ping me if you know, but whats the advantage of using python over html for web dev?

[ember adder]

Django-rest-framework: If I put the token authentication class in the class list settings in config, Token Authentication does not work. It only works if I put the class in the view class variable

# does not work
# myproject.config.settings.base
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    ],
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated',
    ]
}

# works
# myproject.views
class MyListApiView(generics.ListAPIView):
    authentication_classes = [authentication.TokenAuthentication]
    serializer_class = serializers.MySerializer

I really don't understand why TokenAuthentication class specified in the settings won't work, but if provided in my view it will. SessionAuthentication works fine and it's specified in settings....

im tryna make a small zombie game where some zombies chase after 2 players, but i can only get it to only go after one or have it so that one of the players control X axel and the other one Y

                 if (zombie.x < player1X) {
                     zombie.x += zombie.speed;
                    }

this what i use, you know how to fix it?

I found out how

[stable bear]

How do you send a post request after a button click or after any other action except sending input to a form?

[quiet river]

With php?

&_POST

[stable bear]

using django/flask/python/javascript/html/css as this is a python server

[quiet river]

Or something

Ah

Html

<a href

Or javascript on click

Html for ur example is easier

[stable bear]

but what about if you want to click a button to search a database and then outputs a result?

[quiet river]

Php

Thats the only thing i know

Idk about flask but for that i use php

Common use for that

Just search on google lmfao

[outer apex]

Check out events and how to add event listeners. If you're in a form, you can catch the submit event. If it's a button, you can catch the click.
Here's some docs for the click event:
https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event

Check out Fetch API for sending requests and handling the response
https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch

Hopefully with these two resources you can string them together to do most of what you're asking about..

[stable bear]

thanks! is it also possible for a button to make a form with no inputs and just a submit button, and send a post request in that way?

[outer apex]

yup

[serene depot]

https://www.synopsys.com/glossary/what-is-owasp-top-10.html start from OWASP 10 and go further
The worst security paranoia is intended for any web sites that deal with user payments
and even 10 times worse security paranoia for web sites which KEEP user data for payments
and even Worse than that, if the web site have a really big amount of transactions
In order to pass those security measures, the person is required to go through PCI DSS complaince https://stripe.com/guides/pci-compliance here you can find documents regarding that

As far as I remember electronic commerce web sites which do not store user data, need to pass only lightweight 80 pages PCI compaince version
And those who keep user payment data, there should be document for 300-600 or more pages

Found

Lightweight PCI DSS compaince is SAQ A-EP category

A-EP    
E-commerce merchants who outsource all payment processing to PCI DSS validated third parties, and who have a website(s) that doesn’t directly receive cardholder data but that can impact the security of the payment transaction. No electronic storage, processing, or transmission of cardholder data on merchant’s systems or premises.

Applicable only to e-commerce channels.

https://www.pcisecuritystandards.org/documents/PCI-DSS-v3_2_1-SAQ-A_EP.pdf?agreement=true&time=1648025173211

Here is the lightweight, 55 pages security check for the situation A-EP above

Security is a thing going all over the architecture of the web sites, in frontend, backend, infrastructure. PCI DSS Compaince summarized all the weak spots the organization should check and security measures to implement for any type of product

Security can be in your code, to fix all the default settings
Security can be different ways you implement encryption / storage of user data at server and client side
Security can be using Vault secret storages
Security can be in setting up permission managing system for your system admins
Security can be tools that make automatic checks for the password leaks to to git or docker images

Multiple was, PCI DSS complaince tells you that

Lets say, there is a reason why big corps have Security departments and even DevSecOps profession was born 😉

Yes. compiling to PCI DSS compaince is part of Stripe 😉 They help to guide to to make the ride as smooth as it is possible

I discovered about PCI DSS complaince because I tried to add Stripe in the past

https://www.pcisecuritystandards.org/documents/PCI-DSS-v3_2_1-SAQ-A_EP.pdf?agreement=true&time=1648025173211
Try to make sense of A-EP self assessment for attestation of compaince

it should be the easiest possible way to get Stripe and being security complaint, just 55 pages

as long as u make sure

bro

i told you i want to "tab" with selenium

like select what (clickable) element i want

[feral spindle]

Did you want to select an element or press tab

[next turret]

select an element

which is basically what tab does when you press it

but when you press tab it won't select whatever element you want

[feral spindle]

getelementbid or something

byid*

[next turret]

and how do i select it

[feral spindle]

focus or click probably

[next turret]

ok

but help me for this:

[feral spindle]

You should really read the documentation

[next turret]

i need to do this for video thumbnails

how do i do it?

[feral spindle]

Documentation explains how to select stuff, Reading it for selenium is especially important because it’s designed for this stuff and tells you about it

[next turret]

show me where it says how to select stuff

[next turret]

and again, how do i do it for that

[feral spindle]

Google selenium select elements

[next turret]

bro

that's basically "do it urself"

which is bs

because that is why i am seeking help

to get help not be told "do it yourself"

if you have an open page of the docs, then give me that page

  id = db.Column(db.Integer, primary_key=True)
  email = db.Column(db.String(150), unique=True)
  password = db.Column(db.String(150))
  first_name = db.Column(db.String(150)) ```

in models.py

[covert yew]

whats the note model

can I see that?

[frank rampart]

sure

  id = db.Column(db.Integer, primary_key=True)
  data = db.Column(db.String(10000))
  date = db.Column(db.DateTime(timezone=True), default=func.now())
  user_id = db.Column(db.Integer, db.ForeignKey('user.id'))
  notes = db.relationship('Note')

[covert yew]

move the notes in the Note model to the User model

[frank rampart]

the notes variable to the user or the entire thing?

[covert yew]

Like this

class User(db.Model, UserMixin):
  id = db.Column(db.Integer, primary_key=True)
  email = db.Column(db.String(150), unique=True)
  password = db.Column(db.String(150))
  first_name = db.Column(db.String(150)) 
  notes = db.relationship('Note')

class Note(db.Model):
  id = db.Column(db.Integer, primary_key=True)
  data = db.Column(db.String(10000))
  date = db.Column(db.DateTime(timezone=True), default=func.now())
  user_id = db.Column(db.Integer, db.ForeignKey('user.id'))

works?

In Django, is it possible to update a relationship "backwards"? For example, model.objects.update(x=[1, 2, 3]) where x is the related_name of a foreign on some other model.

I know it is possible with .set(), .add(), or .remove() if I have a specific instance of the model. But I want to do it in bulk like shown above.

By the way I tried it with that exact syntax and I get the cryptic AttributeError: 'ManyToOneRel' object has no attribute 'get_db_prep_save' which comes from some Django internal stuff but ultimately originates from that update() call.

[fair agate]

I'm working on a rather large scale project using Python and some JS, FastAPI, disnake among others. I'd be happy to share more about it.

[indigo kettle]

perhaps some simple example of your issue would help but I think the answer is no, you should update it from the other side

but I think it's still possible to do in bulk

[proper hinge]

I thought I already gave an example but I can elaborate. I have two tables, A and B. Table A has a FK to B, and its related_name="x". Thus, B.x exists.

Let's say I have a three rows in A with IDs 1, 2, and 3, respectively. I want to make all three rows relate to the same B. I want to be able to do something like B.objects.filter(pk=1).update(x=[1, 2, 3])

[indigo kettle]

yes sorry, it just still wasn't clear to me.
So instead you should get the queryset for the A model and I think you can update the foreignkey in bulk

A.objects.filter(id__in=[1, 2, 3]).update(b=B.objects.get(pk=1))

[proper hinge]

Thanks. For some reason I was imagining it to be more complicated to do in the other direction but that's not bad at all.

[indigo kettle]

np

A.objects.filter(id__in=[1, 2, 3]).update(b=1)
I think it's valid to just give the pk of the foreign key

[untold scroll]

I'm trying to execute a .py I created inside a django app, but it keeps giving me this error everytime I try to import a model from models.py:

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I wanted to dump some scrape into the database, and the scrape.py (file I'm trying to execute) works completely fine until I import the BlogPost model, which comes from model.py

The app is already added to the "INSTALLED_APPS" area, that's why I'm not understanding why it's saying it's not configured. I did run migrations already.

[indigo kettle]

some set up happens when you start up a server or get into the django shell that doesn't happen if you just try to run a script directly that tries to utilize django's models

you'll want to run that script inside of the django shell or maybe it's possible to do what they're saying and run settings.configure() at the beginning of your script after importing from django.conf import settings

your options are

• create a management command https://docs.djangoproject.com/en/4.0/howto/custom-management-commands/
• do the settings.configure() thing
• run your script inside of the django shell

python manage.py shell < myscript.py

if it's just a one time thing, I'd just do the 3rd option

if you'll use this over and over again, I think making a management command is good
Then you can call it easily like python manage.py mycommand

I'm trying to apply this constraint in Django, which is supposed to disallow a null sensor_id if the type is NOT "man"

models.CheckConstraint(
    name="auto_sensor_not_null",
    check=~models.Q(type="man") & models.Q(sensor_id__isnull=False),
),

However, the migration fails with an error stating that some row violates this constraint.

When I print the rows of the table, there is only one row that has a null sensor_id, but that is the one case where it acceptable since the row has "man" as the type.

1 param1 None man
2 param2 0 auto
3 param3 1 semi

What am I missing? Did I write the condition incorrectly?

Ah yeah I forgot something. It's failing because the type is manual. I need an | models.Q(type="man") to allow it

But then it just simplifies to models.Q(type="man") | models.Q(sensor_id__isnull=False)

So yeah, problem solved.

[muted ether]

Hey guys, this is probably a more opinion-based question rather than one with a definite answer, which is why I'm posting here. I currently have a Django app set up so that it auto-generates a secret key, and writes it into its settings directory when it doesn't detect a key file. Are there any major security implications I should be worried about, or is this approach solid?

[shadow salmon]

I don't see anything wrong with that. As long as it's generating strong keys.

[inland oak]

This approach is silly

You need to keep the same secret key
In order to have users auths kept valid

Depending on where is it used, their passwords hashes can depend on it

[inland oak]

And additional sillinies that u keep persistent data from Django

It is not great. Better to keep it as stateless as possible

While moving all persistent data to dbs

It is more... Cool for future infrastructure development

More room for flexibility with it

Like deploying in AWS your app as container application directly

Secret keys should be injected as env variables

[shadow salmon]

Well he said it only occurs when it doesn't detect a key file. So it's just a one time thing. It would be the same as going into your python REPL, generating the key, and pasting it into your .env file once.

So it should be fine if that's what he meant.

[indigo kettle]

if you deploy an app with this strategy I assume the key will get overwritten on deploy because the secret key shouldn't be stored in the repo. I supposed it could be, assuming that the repo is private but then why would you generate a key at all, just hardcode it

[inland oak]

I don't like the writing to file step. It assumes the application willl be having persistent attached volumes. Unless there is a critical emergency for that. Django container should not have it

plus defaults should be treated carefully. And in my opinion, secret key is the thing you don't want to fall back to random default, better to get an error if the env is not provided

[shadow salmon]

Yeah, absolutely that's all true. Wasn't thinking about that since all he asked about was security implications.

[muted ether]

That's true. Thanks for the feedback.

[glass island]

what's a good way of versioning?

https://www.django-rest-framework.org/api-guide/versioning/#urlpathversioning

I want to do url path versioning

isn't making another app better then just point the url to that?

django btw

does anyone know how to get the image metadata uploaded UploadFile method of fastapi? as per docs, it only declared filename and filetype, but i need specific metadata like image dimension and dpi

Hello i getting error in template of html

[ocean slate]

Hello everyone.

I want to make a website where I can write code and execute or run the same code and it gives the output. Basically the problem is that I want an online code editor or compiler which supports multiple languages, how can I do this?

[jade minnow]

so.. replit? or heroku? or w3schools?

[ocean slate]

heroku is a deployment server

[jade minnow]

right

[ocean slate]

what I have to do?

[jade minnow]

i have no idea

you probably need to setup like

virtual envs

and storage, vcpus, vram, etc

[ocean slate]

ok thanks

[bright spindle]

does webhooks ever return error codes

and is there any standard to it

[unique shore]

I mean if the content isn’t found, can’t be retrieved, can’t be parsed there would be an error

[feral spindle]

Replit

U gotta do replit

[bright spindle]

i mean for example, the user and group doesnt exist

[unique shore]

replit is bad

[feral spindle]

I 100% reccomend replit

[ocean slate]

what is replit

[bright spindle]

budget ide

nah jk, web-based ide

[feral spindle]

It’s easy to install stuff, run discord bots, websites, tkinkinter etc

[bright spindle]

doe it's superseeded by pycharm, better than vsc(web version)

[unique shore]

Don’t use it. Check out VSCode

[feral spindle]

If you want free and online I recommend

[ocean slate]

yes I want free

[unique shore]

VSCode

[feral spindle]

The ide got a theme update which I hate but hey it’s great for free

[ocean slate]

it supports all langguaes?

[unique shore]

VSCode supports almost all languages

[ocean slate]

can I use vs code in my website

?

[feral spindle]

It supports a ton considering it’s free

[bright spindle]

just get visual studio code, or PyCharm Community (for more... difficult projects)

[feral spindle]

He wants online

[bright spindle]

ah

[unique shore]

GitHub workspaces allows you to use a VSCode like editor in the browser

[bright spindle]

yeah vsc and replit is only options

github workspaces is snailspeed

[unique shore]

Just get VSCode app

[bright spindle]

also its ran by vsc

[ocean slate]

Should I clear my complete project details to you all so that you can suggest me which is goo

[feral spindle]

But you can deploy a flask server hella damm fast on replit

[ocean slate]

good?

[bright spindle]

why do online code editor tho

[feral spindle]

I know a guy who runs s api and discord bot on it

[unique shore]

Please don’t use replit…

[feral spindle]

And I’m setting up a bandwidth miner on it

[ocean slate]

I work on flask

[feral spindle]

Ye I recommend

Don’t ever publish anything unless you are fine with people stealing code

[jade minnow]

i use it for web dev but i also put its cname through cloudflare so it isnt 100% ass

[feral spindle]

It’s free u gotta love it

[jade minnow]

also can i use the exact same paramaters for text-shadow as i can for box-shadow

[ocean slate]

I am creating a website for my college for coding contests. In which questions will be there and when a student click on a question a new page loads having that online code editor(or compiler) and run the code on same time

I can do front-end, backend, database

[jade minnow]

are you gonna try and get them to get a specific output

[ocean slate]

Only problem I am getting is how to add that editor

[ocean slate]

yes

[bright spindle]

flask, underdeveloped websites, mostly for people who gonna make lightweight/low knowledge stuff

[feral spindle]

They have editor embed

[jade minnow]

https://www.codingame.com/multiplayer/bot-programming/code-royale

[bright spindle]

except for a few who goes all the way with it, api's can be done efficiently (using multiple libraries)

[ocean slate]

the answer(or output) of that question only

[jade minnow]

literally thi

[feral spindle]

Experience everything then choose

[jade minnow]

https://codebattle.hexlet.io/ or this

any language

same output

[ocean slate]

is this for code editor?

[jade minnow]

for what your literally trying to do

it already exists

[ocean slate]

where?

How I can use and apply it to my website

[jade minnow]

i frame

[ocean slate]

https://codebattle.hexlet.io/games/71699?level=elementary

[ocean slate]

I want exactly same page like this which has question(task) and editor

[jade minnow]

use codepen

or somethign

you can make the problem

share it to them

give them the task

[ocean slate]

and then.

I am new in this please help

[jade minnow]

are you doing in-person?

for your coding thing

just like

walk around

[ocean slate]

means?

[jade minnow]

if they get it

[jade minnow]

theres people in the smae room

you arent on like

a meeting

call

[unique shore]

Instead of replit, try a beginner friendly IDE like Mu or Thonny

[ocean slate]

online for my site

[bright spindle]

im still bummed over how webhook exception handling is done, if i get error in code do i just... leave it

[unique shore]

you don’t need an online IDE to make a website

[ocean slate]

then?

[bright spindle]

i got a no module named project.chat.models error when attempting to do import .models from project/chat/consumers.py to the directory project/chat/models.py. Settings file is located at settings/base.py, and project, chat and settings folder all contains __init__.py. Additionally, chat is added to the INSTALLED_APPS variable, and contain the correct apps.py format to be detected. Of course git forgot to commit the file

[gritty vapor]

Hello everyone 🖐️😃

I'm new to python web development (extreme beginner), can someone help me from where should I start the basics to web dev using python like some tutorials or some advice will be helpful.
Thanks in advance innocent

[covert yew]

first learn the basics of python (variables, lists, data types, functions, classes ect..)
if you already know that then choose a framework to work on such as flask, django or fastapi
and learn to work on that framework read a doc or go through a tutorial

[vapid jay]

Anyone have experience with azure hosting?

[gritty vapor]

I've learnt basic python. I'm beginner in web dev field so which one will be most beginner friendly framework ?

[sand sail]

flask is a pretty good place to start

[covert yew]

yea I think flask would be good

[ocean slate]

dm me

I am creating a website for my college for coding contests. In which questions will be there and when a student click on a question a new page loads having that online code editor(or compiler) and run the code on same time

Only problem I am getting is how to add that editor

[sand sail]

look into "ace editor", there's a few prebuilt js code editors but you'll have to handle compiling/testing the code yourself

[echo geyser]

Is this the right channel to ask for elasticsearch help?

[next turret]

anyone?

that wasn't soled

[unkempt juniper]

#help-potato i'm using flask, need help

[stable bear]

flask beginner project ideas?

[outer apex]

Just saw your message in the channel. I think you might need to provide an absolute path to the tokens.json file. I don't think your app is able to find that file, hence that TypeError's message
Can you share the complete exception? Hopefully it'll show specifically where it's erroring out

[bronze palm]

are you already past register and login Saki?

other wise a login, and register system are always a good start

@stable bear

[stable bear]

yes

i would like something involving login and register as i know how to implement those

[bronze palm]

just make a simple system for it and load a page

so not logged in go to x page other wise go to y page

[stable bear]

done that

[bronze palm]

alrighty next thing is then have you done much with databases yet?

with sql alchemy?

[stable bear]

i have done some but not much

i made a to-do list

for each user who logs in

[bronze palm]

I'd suggest focusing on a blog site with articles, or if that is to much a permission system with users

where different users can access different pages that others can't

that should help you getting used to the relational database system

[untold scroll]

You should probably aim doing that with CSS or Bootstrap instead of inline HTML. It's much easier and makes the html less messy. There are a few articles that should be able to help you with that, I think this is a good place to start:

https://www.w3schools.com/howto/howto_css_images_side_by_side.asp

[jovial blaze]

I'm trying to do this inside of a .MD file so the questionable choices continue. Is CSS supported in MD files?

[untold scroll]

Oh ok. Inline CSS is supported

but if it's for github I'm afraid they don't support it. It kind of goes against the purpose of .md files anyway to make things simpler.

[jovial blaze]

Yeah it's for GitHub. It's annoying that CSS isn't supported but I kind of expected that

It didn't work..

[warm gale]

If my only option of retrieving something in javascript is calling this.a.b.c.target, whats the proper way to make sure a, b, and c are not undefined?

Also, does this situation have a name? Where you're calling the child of a child several layers deep?

Thanks

[wheat hamlet]

I'm fairly new to web development and want to make a web application that I can use to communicate between 2 separate applications. My only concern for now is, how do I make some sort of event in python? An event that is triggered when someone requests the web server?

[swift wren]

no no, so what framework are you using

flask or django orrr

[wheat hamlet]

flask

since it will just be a small project

[swift wren]

yeah so flask only does something if you send a request to it

if you send a request to a flask server its going to trigger a response naturally

[wheat hamlet]

doesnt django also do that..?

[swift wren]

yeah django does that as well

[wheat hamlet]

since im new, i will explain what im trying to make

[swift wren]

all backend frameworks work off requests

[wheat hamlet]

yeah ive made some practice websites with both django and flask

but for now thats really the only thing i understand

what i want to know is how i can communicate between this web server and another separate application

for example

how can i trigger an event in a discord bot if a request is sent to the web server

something like that

thats where im stuck

and its frustrating

[ivory kiln]

i'm a bit confused what the file structure is supposed to look like in a standard django application

im trying to render a html

using django.shortcuts.render

but when i pass the html path its just saying it doesnt exist

i printed os.listdir() and it showed its in the root

but i tried every path and its just not workin

[worldly pawn]

@ivory kiln I'm working on a Django project now (first) so I'll see if I can help. I assume you made the basic html template and stored it in the app_dir>template>app_name>html_file? From there you should have referenced it in app_dir>urls.py as a path on the urlpatterns? You also need to make sure to include the app_dir.urls in the urls.py under the project directory.

[inland oak]

Wow. FastAPI looks sick

like Flask, but way cooler

[ivory kiln]

thanks, i fixed that issue

i have a question

[worldly pawn]

cool stuff

[ivory kiln]

im doing ```py
def index(request: wsgi.WSGIRequest) -> HttpResponse:
response = Response(request)
html = response.to_html()
return HttpResponse(html)

[worldly pawn]

I'm trying to get view to only display when logged in. i got the logic done, but I kind of wanted to have a base.html that will be the same throughout, and then only show other elements when logged in. is the use for {% extends %}?

boom. love it!

[royal river]

@manic frost Hi again, is it fine if I ask for some guide on this insertion of variable from a string parameter.

How do I add a code in this chat with properly quoted one btw.

[native tide]

When I enter something in the input, and submit it, it won't show up. Can anyone help me figure out why?

templates/editor.html

<form method="post">
  {% if results %}
    {{ results }}
  {% else %}
    {{ editor.console() }}
    {{ editor.run() }}
  {% endif %}
</form>

main.py

from flask import Flask, render_template
from flask_wtf import FlaskForm
from wtforms import validators, SubmitField, TextAreaField
import os

app = Flask(__name__)
app.config['SECRET_KEY'] = os.getenv('key_thing')

class EditorForm(FlaskForm):
  console = TextAreaField("Let's make some W# Code!", [validators.optional()])
  run = SubmitField("RUN")

@app.route('/', methods=['GET', 'POST'])
def index():
  results = None
  editor = EditorForm()
  if editor.validate_on_submit():
    results = editor.console.data
    editor.console.data = ''
  return render_template('editor.html', results=results, editor=editor)

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

[outer apex]

FlaskForm has CSRF enabled by default and you need to include that hidden input. Here's an example: https://flask-wtf.readthedocs.io/en/1.0.x/csrf/#html-forms

For future reference, the underlying Forms object has an errors attribute that will show you any validation errors (after calling validate or in this case validate_on_submit).

[native tide]

Ahh okay

Thanks

How can I run a Python script in PHP with arguments? Do I just have to insert arguments after path like escapeshellcmd('path', args)?

[wheat verge]

Can someone explain how this function is working how is the result argument getting the "done !"String

[frank shoal]

after 1000ms, it calls resolve("done!"), which is a callback set to alert

it can be rewritten as this. ```js
(async () => {
try {
const result = await promise;
alert(result);
} catch (e) {
alert(e);
}
})();

[sturdy idol]

I’m wanting to write a web application that takes user form input, adds that to a queue, then once the user specifies they are done, it will run a python script for each set of variables (each form) that the user inputs. Is this something that’s doable in Flask? Should I look into other options? If so, could I get pointed to some documentation?

[wheat hamlet]

If I have a flask web app, how is it possible to trigger some sort of event in a separate python application once a request is sent to the web app?

[sand sail]

the simplest way would be to start your other application as a subprocess

[wheat hamlet]

how would that work?

[sand sail]

for example if you had a program helloworld.py you wanted to call when a flask endpoint was hit you would use the subprocess library to open a new process for "python helloworld.py" in the route code

[wheat hamlet]

alright, ill see how it works, thanks

[wheat hamlet]

i have just realized, what if the other python application is already running and i want to trigger some sort of event in it when a request is sent to the flask application

[sand sail]

in that case you need some sort of shared state, your flask application will need to write to a file/pipe/database that your other program is monitoring

[wheat hamlet]

so there isnt some way to trigger an event in a separate application..

alright, how do you just make an event in python

just in general

a general event my code can wait for

[sand sail]

I think you may want to do some reading on how interprocess communication works, the methods I mentioned are how you handle any sort of communication between seperate applications. "Event" queue's for instance are generally implemented using pipes.

[wheat hamlet]

alright ill research on that, thanks for the help

[heavy kayak]

Have any of yall used the mediapipe hands library for any web development?

Or even for experimenting purposes?

[obtuse mantle]

I am new in web development can you suggest me to how to start it

[heavy kayak]

@obtuse mantle Do you know how to code?

[obtuse mantle]

only html and css

I know

[heavy kayak]

What I did a while back to learn how to code and create a website is create a web calendar. Kinda like google calendar. I made a small database to save all the dates and made a nice user log in interface that would also be stored in a database. And there are plenty or resources to use to learn how to make all the components of that.

[obtuse mantle]

So how create a database

[heavy kayak]

You can use videos like this as refrence. https://www.youtube.com/watch?v=o1yMqPyYeAo But the more you do yourself the more you will learn

If you wanna create a real database you are gonna have to learn some sequel, if you wanna make a fake one, you can just make a json file that stores all the info, just go online and search "how to make a database"

[obtuse mantle]

Can i should start js

[heavy kayak]

I would use js yeah

for all the interactive items on the sight, such as clicking on the calender, or adding elements

html and css will just make the shell of the website. the JS is all the interactive code, clicking on a button and a message popping up for example

[obtuse mantle]

I know web HTML and CSS that you tell to me this is not understandable to me

make it simple

[heavy kayak]

HTML and CSS is all the pretty stuff on the website. This is how you make things

Html put pictures

css make picture look pretty

javascript make pictures move and do things by user interaction

[obtuse mantle]

ok and??

what is database

[heavy kayak]

its where you store all the information of the site. User login infromation like username and password.

[obtuse mantle]

if any user sign up in our website where the data goes?

of sign uping

[heavy kayak]

to the database, which can be stored on a server, your local machine, it could really be stored anywhere, just a place that reads that infromation

just forget about the database for now

work on the javascript first

later do the database

[obtuse mantle]

when we get host our website then where the data goes of sign up

[heavy kayak]

Some hard drive that is run on the server

[obtuse mantle]

Is bootstrap relevant in today's world

[heavy kayak]

yeah it is, its a framework that helps you develop a website and make it easier

[obtuse mantle]

Can you use it

[heavy kayak]

yes you can

https://getbootstrap.com/

[obtuse mantle]

bootstrap or tailwind.css

[heavy kayak]

bs

[obtuse mantle]

why taillwind not

[heavy kayak]

Prefrence

[obtuse mantle]

ok

[heavy kayak]

I havent really used it

And tailwind is not a ui kit

while boost strap is

some people prefer one over the other, it all depends

[obtuse mantle]

what is ui kit

[heavy kayak]

A UI kit is a set of files that contains critical UI components like fonts, layered design files, icons, documentation, and HTML/CSS files. UI kits can be fairly simple with a few buttons and design components, or extremely robust with toggles that change fonts, colors, and shapes on the fly.

[obtuse mantle]

can we us both bs and tw

in same file

[heavy kayak]

You CAN but you shouldent unless you know what you are doing

Some of the stuff in both can overlap causing problems later on

[obtuse mantle]

have you any resource for webdevelopment

??

[heavy kayak]

google lol

any question you ask it will have an answer for

[obtuse mantle]

where you learn it

[heavy kayak]

10% school, 90% google

[obtuse mantle]

you not watch any tutorial??

[heavy kayak]

I did, on google, mostly read though

[obtuse mantle]

you understand by only reading????

[heavy kayak]

yeah usually, and testing

[obtuse mantle]

I am using vs code is it good

[heavy kayak]

yeah

[obtuse mantle]

what if I not use any framwork???

[heavy kayak]

thats okay

You dont need it

[obtuse mantle]

so why people use it

[heavy kayak]

So make large scale development easier

[obtuse mantle]

ok

In which age you start webdevelopment

[heavy kayak]

Idk around 15-16

im 21 right now

[obtuse mantle]

ooh

I am just 17

[heavy kayak]

Thats good! Its always fun to start learning new things, if you have any questions just use google

itll be your best friend

[obtuse mantle]

are you doing job

[heavy kayak]

yeah

and school

[obtuse mantle]

so what you study

in school

[heavy kayak]

computer science, web and software development

[obtuse mantle]

how much time you take to frontend

[polar haven]

is there any channel for django ?

[tired shuttle]

hi everyone

im just new to the community

im 18 and Im interested in web development

I would appreciate any guides in this field, eg: what libraries i should know or which framework is better?

[unique shore]

@tired shuttle what type of web dev do you want to do? frontend or backend

or full stack

[tired shuttle]

back_end

[unique shore]

ok

so thats exactly what i do

i would still learn basics of HTML, CSS, and JS (JS mostly as you can do backend with JS)

https://roadmap.sh/backend

i recommend this roadmap

[tired shuttle]

great👍

[unique shore]

i personally use Rust and C# for backend dev. i dont use Python much anymore

[tired shuttle]

i had heard that if u want to be a good back_end developer u should be familiar with HTML and CSS

[unique shore]

yeah you should a bit

it should take a week to do that lol

[tired shuttle]

why dont u?

[unique shore]

like Rust and C# more

and C# is growing massive recently. it has an extremely large ecosystem

[tired shuttle]

aha i thought there r some technichal reasons

[unique shore]

well Rust is miles faster than python

and I choose it because it incorporates many low level concept which I am interested in

[tired shuttle]

how long have u been programming?

and another question is that which framework is better for python?

and how long it will take to become a senior in this field?

[unique shore]

FastAPI is growing in the Python field

[unique shore]

i started programming with Scratch at 5, but I really got into it in 2020

[tired shuttle]

nice

[tired shuttle]

what about django? I have heard about it alot?

[unique shore]

its very good also

but if you don't want everything given to you off the bat, and want to make stuff yourself, don't use it

it is batteries included

[tired shuttle]

???

[unique shore]

idk it depends

[ocean slate]

which programming language u know?

[tired shuttle]

for now just python

[ocean slate]

then learn flask

for back-end

it is beginner friendly

if in future u need help related to flask, the message me personally

I will try my best to help you.

[tired shuttle]

thanks for your guidance🙏

[tired shuttle]

nice u r too friendly👍

how do i stop anything other than output to stop showing in terminal?

[ancient pumice]

Hey there, I have a question about StreamingResponses in FastAPI. I'm passing a generator to a Streaming. The generator keeps getting data over a websocket. So does this work like a FIFO or does it poll for a limited duration to get the data from the generator? Cause I'm a bit confused on what happens if I don't send data over the websocket for a few minutes and then resume sending it.

[dark loom]

Looks like you are running object on an instance. You have to do it on a class.

[indigo kettle]

you manually removed the models, and then removed the migration files?

if so, you may need to also remove them from the migrations table that django creates...

normally, if you created a migration that you actually do not want, you would reverse the migrations and then delete them or just create new migrations which remove the tables

https://docs.djangoproject.com/en/3.2/topics/migrations/#reversing-migrations

There's a discrepancy between the value I have stored in the db and the value I get from fastapi.
Stored DB Value: 9339981860999169

hello, I want to learn about api in python flask

suggest me any good tutorial where i can learn API with flask, I saw many videos but they were not so in deep

[agile pier]

hii, i m using base 64 encode for the image

[unique shore]

You have to learn what REST APIs are first

the basic flask program IS a REST API

[agile pier]

My image is in {{dd.image}}, I want to ask where do I give the value{{dd.iamge}} in

    AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO
        9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" />```

[unique shore]

app.get("/"), which is essentially used in all flask beginner tutorials is a GET request at the index route

[vivid canopy]

can u please tell me why we use def list or create in a rest framework if we have ListCreateView?

[bronze palm]

it allows us to be selective on which kinds of methods we allow, if we disallow methods we don't need faster we get better results

and with generics specifying can be useful like the listapiview is read-only and tis explicit

while the list create isn't

@vivid canopy hope that helps

[vivid canopy]

thx bro)

[bronze palm]

no worries

[cinder whale]

what is the average python web dev's tech stack look like

or feel free to share your own too

[inland oak]

Flask/Django(the most average)+django rest framework/FastAPI
Postgresql (DjangoORM or Sqlalchemy)
Redis/rabbitMQ
Docker
Nginx
Pytest
Gitlab CI
Linux (working with Ubuntu/Debian is enough)

[cinder whale]

thanks DW

oh good to know

ubuntu is what im most familiar with

[inland oak]

Feel free to get acquainted with Alpine for docker images purposes though

[cinder whale]

wait DW, you didnt mention any frontend frameworks

[inland oak]

U asked for python web dev stack

[cinder whale]

[inland oak]

This would be already for person going to full stack road

Anyway.. React or Vue.js

[cinder whale]

ok good

bc im learning react

do you use a css framework too or no

[inland oak]

React or Vue.js
Some sort of related state management system
SCSS

[cinder whale]

Sass ive played with before

my friend is super into tailwind

[inland oak]

Not really, just used SCSS to impement latest project full of custom stuff.

I would use CSS framework for pet projects because I am not designer though

[cinder whale]

yet

[rare oar]

Hey all, I got a weird question and the FastAPI discord is dead

[inland oak]

Alpine Linux is cool for docker. It is really small. 5mb base size

[cinder whale]

figma lets you export code too

[cinder whale]

i will note this down

[rare oar]

I'm having a issue with a background task that I created. Its a simple function that goes in an infinite loop with a sleep and is created by asyncio_create_task. When I run this FastAPI instance under uvicorn everything is working fine and does what it needs to do. However, when I use gunicorn and pass in the UvicornWorker, I can see the task being created, but the function never executes. Any ideas?

[cinder whale]

do you think you will focus on web dev or move to another specialty in future or wait you said you were mostly backend/devops, right? i cant remember

[inland oak]

I will remain in web dev and concentrate on backend/DevOps

My future plans

1. getting hands on fastapi and async related python ecosystem
2. practicing golang
3. learning tekton/argocd as kubernetes native gitlab CI alternative
4. learning Kafka and building microservices architecture around it
5. improving my code quality things to handle really big sized projects
6. practicing with AWS
7. learning secondary cloud infrastructure objects like Vault, Elastic search, mongodb and etc
8. getting more exp with Postgresql, and wishing to try Flyway dB version control system

And I am certainly not going to improve my frontend or anything related to it.
Except may be a bit setting up testing stuff for that

I like infra more than front

I already tried Frontend with Vue.js, so I got the taste of it

It has some certain appeal in simplicity and relaxation, but it is not for me

[cinder whale]

i see

[rare oar]

Front end sucks.

[cinder whale]

there is always need for more backend than frontend i feel like

my background is in DS so it all is new to me

[inland oak]

It is good to know a bit of frontend for general education of web Deb

[cinder whale]

yeah im trying to learn as much as i can for this website project for my software engineering class rn

since it seems the other team members are unreliable

like

they are all CS majors and im the only AI major

why am i the main developer

honestly i will probs end up having to make this entire website by myself. already calling it

but at least i will get to learn stuff

[inland oak]

That is normal. Students are often immature in what they learn.

[cinder whale]

yeah i know but like...these are grad students so i expect some more level of maturity than undergrad

but i guess it seems common in CS programs maybe

[inland oak]

During uni one of other students made a hack with js to pass our computer network exams.
And shared to all other students
Tbh what he did still looks like magic to me

[cinder whale]

i wanted to take a cybersecurity class this summer

but it filled up

🕯️

[inland oak]

I did not even I am going to be web developer until I got first job

Hell, I did not know I would be even programmer until I got taste of first job

[cinder whale]

this seems like its more in line with reality

[inland oak]

For the last one year and half I got certainty with my path and moving into one (two) directions

Backend+DevOps is a nice combo of my choice

Usually people just go backend, or just DevOps, or frontend, or full stack

My choice is just my personal quirck born out of need at the past job of handling everything alone

I started to work in a good company now... But I already got used to certain ownership of Backend and infra at a more intimate level

And it is just stacking well

[cinder whale]

interesting interesting

[cinder whale]

i like DS work and i will explore if i like dev work too, especially this summer (SWD internship), so i may try to follow your path and find a good combination if possible

[inland oak]

DS can make a combo with backend I think

Your future company will value your DS/ML much more if u could code it in not a shitty way

[cinder whale]

i know it can make a combo with DevOps. DS + DevOps =MLOps

[inland oak]

Out of all web devs, backend guys learn the most of code quality stuff

[cinder whale]

yeah maybe can incorporate ML-type of features into software apps (i.e. recommender systems, etc.)

[inland oak]

I suspect it is better to learn minimal viable backend first before diving into MlOps

Because it will give the basic instruments to operate during MlOps

DevOps stuff is meant to be started with person having already some background in other stuff? In Backend or in Ops?

[cinder whale]

yeah thats my take on it too. bc its a a big jump by itself.

[inland oak]

Bwhahaha

Reading article for differences between DevOps and MLops

Checked the author name and nickname...

... My brother.

[marsh minnow]

Anyone knows how can I interact with a source game server console with python in a website?

[unique shore]

some sort of API

[cinder whale]

your brother wrote the article?

[inland oak]

Yeah

Conviniently he is experienced DevOps person which participated in all sort of public activity

[cinder whale]

what did he say the difference was btw

[inland oak]

It is long article written in my native language.

If to summarize his all words.
MlOps = machine learning with DevOps with difference in

1. pipeline for MLops requires not just code as data input, but also data and parameters, and results in model and then release
2. requires more hardware
3. monitoring of the system has some sort of dynamically changeable specifics to what is monitored

Main thing for MLOps to automatize building of model and its training tuning.
That alone will free more time for ML specialist to work more on model.

[cinder whale]

ah that tracks with what ive heard

they even specific tools for it but i wont get into it in this channel

since its OT

[inland oak]

Sigh. What I learn now, he learned already three years ago

It looks impossible to catch up with him

He is pure DevOps though, while I am a hybrid between backend and DevOps. So at least in backend knowledge and general code quality stuff I should be able in theory to surpass him. Not guaranteed though

[cinder whale]

lol its okay. you dont have to compare yourself to him. everyone is on their own path

[inland oak]

Just a classic sibling rivalry ;)

[trail axle]

can u gather input using the backend or would u need to take it using js and send to the python app?

[obtuse robin]

you can for sure gather input using backend
