Check id of foreign key object

Question

Im trying to write a function to check that the user has correct member category.

My models:

from django.db import models
from django.contrib.auth.models import User


class Membercategory(models.Model):
    membercatname = models.CharField(max_length=200)  


class Profile(models.Model):
    user = models.OneToOneField(User)
    mobilephone = models.CharField(max_length=12, blank=True)  
    membercategory = models.ForeignKey(Membercategory, blank=True, null=True)

My user-check middleware:

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

class UserCheckMiddleware:

    def process_request(self, request):

        invalid_user_path = settings.INVALID_USER_URL

        if request.user.is_authenticated() and not request.user.is_staff:

            if not request.user.profile.membercategory(id=426):
                return HttpResponseRedirect(invalid_user_path)
        else:
            return        

The error I get is: Membercategory object is not callable

How should I do the check?

Well, as the error says, Django model instances are not callable. You just want a simple comparison to the ID:

if request.user.profile.membercategory_id != 426:
