Are you sure you want to delete these content types? If you're unsure, answer 'no'. Type 'yes' to continue, or 'no' to cancel: yes }}} At this point, the user has no way to tell whether they should answer 'yes' or 'no'. Usually they will type 'no' until they get bored, say a quick prayer and type 'yes'. ---- Django contains infrastructure to determine how many objects will be deleted. {{{ >>> ct = ContentType.objects.get(app_label='auth', model='group_permissions') >>> collector = NestedObjects(using=DEFAULT_DB_ALIAS) >>> collector.collect([ct]) >>> print(collector.nested()) [] }}} It would be helpful to display the list of objects that will be deleted or at least the number of objects. If the collector returns just the original object, perhaps migrate could even proceed with the deletion without asking.
