do not use has_delete_permission() override not being called on every object when perform delete action changelist.

use signals it. add models.py

from django.db.models.signals import pre_delete django.dispatch.dispatcher import receiver django.contrib.auth.models import user django.core.exceptions import permissiondenied  @receiver(pre_delete, sender=user) def delete_user(sender, instance, **kwargs):     if instance.is_superuser:         raise permissiondenied 

the drawback of method nobody able delete super user. have set users attribute "is_superuser" false before can delete it.
