Django - Extend User Twice Using AbstractUser
I'd like to have both Teacher and Student Accounts in my Django WebApp. Now I have extended the base user using Student(AbstractUser) and AUTH_USER_MODEL='mainApp.Student'. Now I'd like to implement a Teacher Account, using the same approach. But before I wreck my project I wanted to ask for input. Do you think this can work or should I use a OneToOneField or maybe just a is_teacher / is_student boolean? I'd like to avoid using a OneToOneField, as that creates the need to first create a User and then also create a Student / Teacher. -
Cpanel Number of processes exceeds and Django App crashes
I am very new to deploying Python (Django=4.1) applications on Cpanel(Shared). I have successfully hosted one app with celery, redis, etc. The issue is, every time I start using the app, the total number of processes(Cpanel) exceeds(120/120) and the app stops working. I have been trying to learn about the number of processes and how to optimize the application. Yet no success. Can somebody describe the following? What is the number of processes at Cpanel? How is my app related to this? How can I optimize my application? How to keep the application working? This Python(Django, DRF, Celery, Redis, Requests) app is supposed to be used by 5,000 users. I tried to learn about 'number of processes and entry processes' online. No luck. Went through a few articles to learn how to optimize Django app. -

Trying to find out the best way to model my data. I have one table for pokemon types: class PokemonTypesTest2(models.Model): name = models.CharField(max_length=25, unique=True) It just has an ID and name, it will have 18 rows in it.

Django channels add object at wrong model
I am making a chat app with django channels and it has 2 consumers. One is for the team chat and the other for personal. I am adding history for the chat. There are two models. "Chat" and "Chat2".

How can I connect to a locally hosted site within a docker container?
I'm trying to connect to a docker container's locally hosted address. I'm using Django to serve a website within the container, and I want to connect to it on my local machine.

Use API call of payment gateway to change order status from "Pending" to "Completed"
I am using Django python and this is my first year in python programming I am writing a program where the client places an order. So in models.py I have an order object with field "Payment Status" with field choices: Pending and Completed.

If you needed to deploy an empty, running django app frequently, how would you do it? Thanks -
Why is my django_framework so prone to assertion errors
As the title I use "VScode" for programming and the environment is built on "anaconda" I actually simulate a code execution according to the teaching video, but the following errors related to the ".is_valid()" method will appear. The original situation is that the "save" method cannot be called, but when I restart "VScode", sometimes the error occurs Back to normal, in other words, there is no problem with the programming itself. Just encountered another error about the ".is_valid()" method, but this time with the "errors" method... I'm really confused. After all, the code is fine. Where is the problem, the "IDE" or the environment setup...? The "Put" method is super prone to situations!
