I'm using Django 2.0.2. Since Django 2.x, on_delete is a required argument: https://docs.djangoproject.com/en/2.0/ref/models/fields/#django.db.models.ForeignKey.on_delete
I'm getting the following stack trace when I attempt to instal django-security:
Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x10520c7b8>

Should cascade delete if the user is delete.
