Well, after calling .all() you indeed get plain python list and you can't do anything but iterate over it; it's "too late". In this case it appears one should not call .all() and instead call something on the query itself i.e. session.query(Text).???.update(...). I would like to know if and what to insert so that SA would generate UPDATE for objects _related_ (those accessible via association proxy) to these selected objects.
