Easier though is session.query(Container); it'll load from the join of items/ containers so you wouldn't get any non-Container objects. with_polymorphic() only speaks to what subclasses are eagerly loaded and will be available for filtering. Though its something to think about if base classes are not included in WP, should that change the base class; I'd say no, since you are reversing intent. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
