django @login_required decorator for a superuser

In case staff membership is sufficient and you do not need to check whether the user is a superuser, you can use the @staff_member_required decorator:

from django.contrib.admin.views.decorators import staff_member_required

@staff_member_required
def my_view(request):
    ...

If you want to have similar functionality to @staff_member_required you can easily write your own decorator. Taking @staff_member as an example we can do something like this:

from django.contrib.auth import REDIRECT_FIELD_NAME
from django.contrib.admin.views.decorators import user_passes_test

def superuser_required(view_func=None, redirect_field_name=REDIRECT_FIELD_NAME,
                   login_url='account_login_url'):
    """
    Decorator for views that checks that the user is logged in and is a
    superuser, redirecting to the login page if necessary.
    """
    actual_decorator = user_passes_test(
        lambda u: u.is_active and u.is_superuser,
        login_url=login_url,
        redirect_field_name=redirect_field_name
    )
    if view_func:
        return actual_decorator(view_func)
    return actual_decorator

This example is a modified staff_member_required, just changed one check in lambda.

Use the user_passes_test decorator:

from django.contrib.auth.decorators import user_passes_test

@user_passes_test(lambda u: u.is_superuser)
def my_view(request):
    ...

For class based views, creating a reusable decorator:

from django.contrib.auth.mixins import UserPassesTestMixin
from django.views.generic import View


def superuser_required():
    def wrapper(wrapped):
        class WrappedClass(UserPassesTestMixin, wrapped):
            def test_func(self):
                return self.request.user.is_superuser

        return WrappedClass
    return wrapper

@superuser_required()
class MyClassBasedView(View):
    def get(self, request):
        # ...
