Also, auth.user always contains the db.auth_user record of the current
logged in user (or None), and auth.user_id is the logged in user's id (see
http://web2py.com/book/default/chapter/08#Authentication). So, you don't
have to refer to session.auth.user or do a db query to pull the current user
record.
