Yeah, I use this use-case a lot. I never actually search with it -- just usually map the scalar for display needs.
But it appear to recognize the join and automaps if needed: s.query(Foo).filter(Foo.qux == 'abc').first() generates SELECT foo.id AS foo_id, foo.id_bar AS foo_id_bar, bar_1.id AS bar_1_id, bar_1.qux AS bar_1_qux FROM foo LEFT OUTER JOIN bar AS bar_1 ON bar_1.id = foo.id_bar WHERE EXISTS (SELECT 1 FROM bar WHERE bar.id = foo.id_bar AND bar.qux = 'abc') LIMIT ? OFFSET ? here's a gist: https://gist.github.com/jvanasco/13ef28be2b746595e400 -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
