What are Django authentication mixins and how do I use them?

Django authentication mixins are classes that provide authentication-related functionality to your views. They help manage user access and permissions.

Can you give me an example of how to implement a login mixin?

Sure! You can use the LoginRequiredMixin to restrict access to a view. Just inherit it in your view class like this:

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 create a custom mixin?

You can create a custom mixin by defining a new class that inherits from object or another mixin. Implement the desired methods to add your functionality. For example:

class CustomPermissionMixin:
    def dispatch(self, request, *args, **kwargs):
        if not request.user.has_perm('app.permission_name'):
            return self.handle_no_permission()
        return super().dispatch(request, *args, **kwargs)
