How to limit a view to superuser only?

is_superuser isn't a permission, it's an attribute on the user model. Django already has another decorator you can make use of called user_passes_test to perform this check:

from django.contrib.auth.decorators import user_passes_test

@user_passes_test(lambda u: u.is_superuser)
def score_reset(self,...):
    ...

• allowing only super user login
• Django is_staff permission decorator

Above answers seems to be for very early versions of django. They are bit complicated than for the more later version

for django 1.11 here is a bit similar but simpler strategy.

views.py

from django.contrib.auth.decorators import login_required

@login_required
def some_view(request):
if request.user.is_superuser:
    //allow access only to superuser
    return render(request, 'app/template1.html', args)
else:
    //allow access only to user
    return render(request, 'app/template2.html', args)
