Because db.dog.owner is a reference field, it automatically gets the following validator by default: db.dog.owner.requires=IS_IN_DB(db, 'person.id', db.person._format) So, by default, it uses db.person._format (which in this case is '%(name)s'), which displays the names instead of the ids. However, you have overridden the default validator with your own IS_IN_DB, but you did not specify a format. If you don't specify a format in IS_IN_DB, it defaults to '%(id)s', which is why you see ids instead of names. Anthony
