Как создать Middleware, Django для проверки авторизации?

class MyAuthorization:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_request(self, request):
        if not request.user.is_authenticated():
            return HttpResponseRedirect('/')  # or http response
        return None

class LoginRequiredMiddleware:

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_view(self, request, view_func, view_args, view_kwargs):
        assert hasattr(request, 'user')
        path = request.path_info.lstrip('/')
        url_is_exempt = any(url.match(path) for url in EXEMPT_URLS)

        if path == reverse('accounts:logout').lstrip('/'):
            logout(request)

        if request.user.is_authenticated() and url_is_exempt:
            return redirect(settings.LOGIN_REDIRECT_URL)
        elif request.user.is_authenticated() or url_is_exempt:
            return None
        else:
            return redirect(settings.LOGIN_URL)
