the vast majority of queries go through __iter__(), so that's probably all you need. from_self() and get() are not as common - though get() will be used for a many-to-one lazy load in most cases, if this class is the target of a many-to-one relationship(). If you're dealing with mapped classes, a simple enough check is hasattr(MyClass, 'company_id'). Within Query, calling _mapper_zero().class_ gives you this class, assuming the query is against a single full entity like query(MyClass). -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
