Django, redirect all non-authenticated users to landing page

Question

I have a django website with many urls and views. Now I have asked to redirect all non-authenticated users to a certain landing page. So, all views must check if user.is_a

Answer 1

As of Django 1.10, the custom middleware classes must implement the new style syntax. You can use the following class to verify that the user is logged in while trying to access any views.

from django.shortcuts import HttpResponseRedirect


class AuthRequiredMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.

        response = self.get_response(request)
        if not request.user.is_authenticated: # in Django > 3 this is a boolean
            return HttpResponseRedirect('login')
        
        # Code to be executed for each request/response after
        # the view is called.

        return response
