associationproxy has an attribute target_class for the "middle" class: MyClass.my_association.target_class then for the target, 0.7 has "remote_attr". Not in 0.6 but it's just shorthand for: getattr(MyClass.my_association.target_class, self.value_attr) but AP doesn't know what type that is. Suppose it were a relationship, then you'd say: getattr(MyClass.my_association.target_class, MyClass.my_association.value_attr).property.class_ if a column: getattr(MyClass.my_association.target_class, MyClass.my_association.value_attr).property.columns[0] etc. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
