You could use a callback for that. In Web2py you can register a function to be called before or after a certain database action is performed. Inside the function you can check for conditions and by returning True you can choose to abort the action. See http://www.web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#callbacks-on-record-insert-delete-and-update for details.
