Our e-learning platform will offer courses on various subjects. Each course will be divided into a configurable number of modules, and each module will contain a configurable number of contents. There will be contents of various types: text, file, image, or video. The following example shows what the data structure of our course catalog will look like:
Subject 1 Course 1 Module 1 Content 1 (image) Content 2 (text) Module 2 Content 3 (text) Content 4 (file) Content 5 (video) ...

from django.db import modelsfrom django.contrib.auth.models import Userclass Subject(models.Model): title = models.CharField(max_length=200) ...
