Thank you for the suggestions, Massimo. I've tried to update the model here:
http://code.google.com/p/publicradioroadtrip/source/browse/models/db_custom.py based on your suggestions, and the example app here: http://www.web2py.com/book/default/chapter/03#A-Wiki However, if I use the line: Field('created_by', db.auth_user, default=auth.user_id, writable=False, readable=False), I receive the error: KeyError: 'auth_user' http://pastie.textmate.org/1188236 Tell me, is the issue with the user table related to the issue of making a many-to-many relationship between stories and roadtrips?
