I think you have mistake : Field <http://web2py.com/book/default/docstring/Field>('tags','list:reference tag'))
In that case "tag" is you table... So when use list:reference you don't use the db.auth_user just "auth_user" Also you don't specified the db.auth_user.username since username is not a default field of auth_user and you maybe want to specified the representation of the list:reference field since it is a integer and replace it by the name or email of the user... To do that you need to user .represent() I let you read futher in the book..
