Hi guys, I just wanted to confirm this. The web2py book (link = http://www.web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#callbacks-on-record-insert-delete-and-update) says: "The return values of these callback should be None or False. If any of the _before_* callback returns a True value it will abort the actual insert/update/delete operation."
But my experience differs, I am comparing the value in db ("query set") and the value I am about to insert ("fields"). CRITERION: If the "query set" is a smaller value, abort the update operation. So, per the instruction in the web2py book, I made it like so: db.table._before_update.append(lambda s,f: qs(number)<f['number']) which means the "query set" is smaller than the "fields", then, it's TRUE, so, abort update. But it didn't work until I switched the operator sign to make the statement FALSE, like so: db.table._before_update.append(lambda s,f: qs(number)>f['number']) which means the "query set" is NOT smaller than the "fields". It would abort update. Am I confused about something or does the web2py book need an edit/update?
