django - How do I create objects during a data migration? -


i'm trying create new object during data migration. far can tell should use orm.object() create new object, doesn't seem working:

def forwards(self, orm):     o in orm['app.objects'].objects.all():         ...         n = orm.newobject()         n.date = datetime.date.today()         n.object = o         n.save()

i error

attributeerror: 'nonetype' object has no attribute 'date'

when run migration, suggesting n not being created properly. doing wrong?

i create these as:

def forwards(self, orm):     obj in orm['my_app.modelname'].objects.all():         orm.someothermodel.objects.create(some_property=obj.some_property)
