I haven't seen how to do this using the relation directly. I do: session.query(Someclass).join(OtherClass).filter_by(OtherClass.field==somevalue)
I did do some experimenting with a more abstract approach, but did not find any need in my application. The only advantage is that it takes away the need to know up front what is the name of the other class. That might be useful if you are building a framework based on SA, but not in most applications. otherclas = SomeClass.relname.property.mapper session.query(Someclass).join(otherclas).filter_by(otherclas.c.field==somevalue) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
