Important advise: use the book as first help. It is a precious information source.
From http://web2py.com/books/default/chapter/29/07?search=validators#Validators Built-in validators have constructors that take an optional argument: IS_NOT_EMPTY(error_message='cannot be empty') error_message allows you to override the default error message for any validator. Here is an example of a validator on a database table:db.person.name.requires = IS_NOT_EMPTY(error_message='fill this!') where we have used the translation operator T to allow forinternationalization . Notice that default error messages are not translated. >From http://web2py.com/books/default/chapter/29/11?search=form.errors we know that: The color of the errors is given in the CSS code in "layout.html".
