You could add a pre_delete signal [1] to your model that only allows deletion of items if they have no children etc. and raises an exception with a friendly message otherwise. I think this would kick in after that page appears in the admin though so you may still want some way to change that page and have the signal as a safety net. -- G [1] http://docs.djangoproject.com/en/1.1/ref/signals/#django.db.models.signals.pre_delete -- You received this message because you are subscribed to the Google Groups "Django users" group.
