💡 Hint

Common Mistakes

Inheriting from object which does not provide middleware features.

Using non-existent base classes.

The middleware class must inherit from MiddlewareMixin to work properly in Django.

Common Mistakes

Using is_active instead of is_authenticated.

Using redirect function without importing HttpResponseRedirect.

Use is_authenticated to check user status and HttpResponseRedirect to redirect to login.

5fill in blank

Fill all three blanks to import HttpResponseRedirect, define middleware class, and implement process_request.

Django

from django.http import [1]

class [2]([3]):
    def process_request(self, request):
        if not request.user.is_authenticated:
            return HttpResponseRedirect('/login/')

Drag options to blanks, or click blank then click option'
