Mixins vs Decorators for Django

decorators.py

from functools import wraps

class ViewDecorator(object):
    def __init__(self, decorator_class):
        self.decorator_class = decorator_class

    def __call__(self, *args, **kwargs):
        # Pretend that there is a generic decorator wrapper here
        pass

login_required = ViewDecorator(LoginRequired)
        

mixins.py

from django.conf import settings
from django.http import HttpResponseRedirect

class LoginRequired(object):
    
    def dispatch(self, request, *args, **kwargs):
        if self.check_logged_in(request.user):
            return super(LoginRequired, self).dispatch(request, *args, **kwargs)
        else:
            return self.not_logged_in(self):

    def check_logged_in(self, user):
        return user.is_authenticated()

    def not_logged_in(self):
        return HttpResponseRedirect(settings.LOGIN_URL)

views.py

@login_required
def function_based_view(self, request):
    return HttpResponse("Testing")

class ClassBasedView(LoginRequired, TemplateView):
    template_name = "secret.html"
