Given class Person: id class Topic: id class Person2Topic : id topic_id - fkeys topic(id) person_id - fkeys person(id) class Message: id person_id_author - fkeys person(id) topic_id - fkeys topic(id) I wanted to select by joining the Person2Topic table directly, with a filter
query( Message )\ join( Person2Topic ,( Message.topic_id == Person2Topic.topic_id , Person2Topic.person_id = 1 ) This generates errors, because sqlalchemy doesn't have an fkey on Message.topic_id = Person2Topic.topic_id i can only figure out how to do query by doing intermediary joins query( Message )\ join( Topic , ( Message.topic_id == Topic.id ) )\ join( Person2Topic ,( Topic.id = Person2Topic.topic_id )\ filter( Person2Topic.person_id = 1 ) is it possible to do a select like I originally wanted ? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
