How do I use authentication mixins in Django?

Authentication mixins in Django are used to restrict access to views based on user authentication status. You can use mixins like LoginRequiredMixin to ensure that only authenticated users can access certain views.

Can you show me an example of using LoginRequiredMixin?

Sure! Here's a simple example:

from django.contrib.auth.mixins import LoginRequiredMixin
from django.views.generic import TemplateView

class MyProtectedView(LoginRequiredMixin, TemplateView):
    template_name = 'protected.html'

This will redirect unauthenticated users to the login page.

What if I want to customize the login URL?

You can customize the login URL by setting the login_url attribute in your mixin:

class MyProtectedView(LoginRequiredMixin, TemplateView):
    login_url = '/custom-login/'
    template_name = 'protected.html'

Are there other mixins for permissions?

Yes, Django provides several mixins like UserPassesTestMixin for custom permission checks and PermissionRequiredMixin for checking specific permissions.
