Another Question: what is the performance drawback in using IS_IN_DB() validator in a form? From what I understand, web2py checks if the query passes against the database before doing a database insert or any other action. I would like to know if there would be a performance degrade as the number of records in the database increases and that means the more records the IS_IN_DB() validator has to check itself against? Thanks
