this is pretty basic for web2py models .... Every Field() "requires" attribute can be a single or a list of validators. If you need to check against multiple validator, append them, as db.table.field = [validator1, validator2] There is one caveat: when there is more than one validator no select widget would be build for IS_IN_DB or IS_IN_SET (no way to tell what other validation will occur)
