Cannot set user.is_active to false

Question

I have a custom user model and I am trying to deactive the user but it is not saving. There are also no error messages.

My model:

from django.contrib.auth.models import AbstractUser
from model_utils import FieldTracker

class User(AbstractUser):
    # ... just some additional attributes

   objects = UserManager()
   tracker = FieldTracker()


u = User.objects.get(email="[email protected]")
u.is_active = False
u.save()
u.refresh_from_db()
u.is_active # Still returns True but should be False

Solution I found the reason why the save did not work is the Fieldtracker. Unfortunately, it is not mentioned in their documentation. The FieldTracker cannot handle the the attribute is_active=True of the base class. Workaround is to use FieldTracker to track specific fields (except is_active):

email_tracker = FieldTracker(fields=['email'])
