user_passes_test decorator redirecting to login even when result is True

Question

This is my decorator:

def is_clinic(user):
    user.groups.filter(name='Klinik').exists()

And my view:

class Index(View):
    @method_decorator(login_required)
    @method_decorator(user_passes_test(is_clinic, login_url='/clinic_only.html'))
    def get(self, request):
        return render(request,"index.html")

user is in group. I tested it with shell and decorator is returning True for sure.

When i navigate to url, django is redirecting me to clinic_only.html

Answer 1

You have forgotten to return the result of your query. Therefore, your function implicitly returns None , and the decorator redirects to the login page. You should have:

def is_clinic(user):
    return user.groups.filter(name='Klinik').exists()
