Greetings Alchemists, Is it possible to define a hook in a mapped class that will be called to test the sanity of an instance before it gets committed?
As an example: class Item(object): def _pre_commit(self): assert (self.dry_weight + self.fluids) < 50 mapper(Item, items_table) I don't want to put the test mutators of dry_weight or fluids since it's OK to have a temporary inconsistent state as long as the state is consistent at commit time. I see that some of this functionality if covered by MapperExtention but since the test is only related to Item I'd rather put the test in it. -- Yannick Gingras --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
