Django: check what would be deleted when I delete an object, using a transaction

gistfile1.txt

>>> from django.db import transaction
>>> transaction.set_autocommit(autocommit=False)
>>> o = Organization_v2.objects.get(name='pdemo')
>>> del_info = o.delete()
>>> del_info
(1404, {'data.Property': 408, [..more stuff..], 'data.Organization_v2': 1})
>>> Property.objects.filter(scope__organization_id=o).count()
0
>>> transaction.rollback()
>>> o = Organization_v2.objects.get(name='pdemo')
>>> Property.objects.filter(scope__organization_id=o).count()
408
