Have you had experience implementing an authorization system in Django projects?

Yes, Django has a built-in authentication system that can be used and extended to meet the project's needs.

Experience in implementing an authentication system typically includes:

• Using the built-in User model from django.contrib.auth.
• Setting up authentication via forms or APIs (e.g., using django.contrib.auth.views.LoginView).
• Managing permissions through groups and permissions (Permissions, Groups).
• Creating a custom user model if necessary, inheriting from AbstractUser or AbstractBaseUser.
• Implementing registration, password recovery, email confirmation.

An example of simple usage of the built-in authentication:

from django.contrib.auth import authenticate, login
from django.shortcuts import render, redirect

def login_view(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            return redirect('home')
        else:
            error = 'Invalid credentials'
            return render(request, 'login.html', {'error': error})
    return render(request, 'login.html')

Thus, experience with authentication in Django includes understanding the built-in tools and the ability to adapt them to the project's tasks.
