[html-formfu] Perl DBI with FormFu

[Manu Kaul]

Hi,I am still trying to get my head around how FormFu works and still
reading through the documentation to understand what is possible and what is
not. So bear with me if I am not making sense :)
But I want to be able to list out all the validations that are required on
the form i.e. required fields, checking field lengths, checking field values
against regular expressions, etc in the Config::General XML file. And then
use that in my Catalyst project with FormFu.
But instead of going   $form->create() or  $form->update... which will use
FormFu::Model::DBIC I think, I want to be able to pass the form values to a
custom method written in my Model class.
Also was wondering how I can then display the DEFAULT values for a form when
in EDIT mode, when I have a custom Model class in the background.
Is it possible for you to provide me some sample code that caters to what I
am doing or point me out some sample projects that are using FormFu so I can
see how the configuration aspects of form validation will work. Then I can
work on passing these off (once past validation) to my custom Perl DBI MODEL
class.
Hope this is making sense?


Cheers,
MK

The greater danger for most of us lies not in setting our aim too high and
falling short; but in setting our aim too low, and achieving our mark.
