It is not a web2py bug. web2py it is just telling you that GAE cannot do this, because there are no expressions on GAE.
Instead of this: db(db.user.id == session.user_id).update(post_num = db.user.post_num + 1) do db(db.user.id == session.user_id).update(post_num = auth.user.post_num + 1) and you will be fine.
