Question

In the django admin, when a user is given superuser status, I wish to perform a check.
I want to see if the user email is from in the form of *.company.com

What is the best way to do this?

Answer 1

Create a signal:

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

def check_superuser(sender, instance, signal, *args, **kwargs):
    if sender is User and instance.is_superuser and not instance.email.endswith('@company.com'):
        ...

post_save.connect(check_superuser, sender=User)

So now, every time an instance of User is saved, it will run the above check_superuser method
