It sounds like you need to update the .tables files to match your database and models.
I believe you need to set both migrate=True and fake_migrate_all=True for the fake migrate to regenerate the .tables files. Here's the logic in the book: http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer?search=fake#Migration-control-summary Have you tried setting both migrate and fake_migrate_all to True?
