You can also make your own metaclass if you wanted, and pass it in as metaclass=MyMetaClass, or you can use the individual components within declarative_base explicitly if you wanted to roll it yourself. This is all in the docstrings for declarative. > Another somehow related question is there any plan for declarative > base to support inheritance ala django ? declarative supports all three of SQLA's table inheritance forms fully. It pretty much happens automatically when you make a subclass, and you just need to pass along polymorphic_on/ polymorphic_identity into __mapper_args__. If Django supported some kind of inheritance scenario that we don't I'd be very interested to see that :) . --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
