NAME

       HTML::FormFu::Validator - Validator Base Class

SYNOPSIS

DESCRIPTION

METHODS

CORE VALIDATORS

BEST PRACTICES

       Try to avoid using callbacks if possible. Below is a more maintainable and reusable approach, which also keeps the code out of the
       controller.

       A normal application's directory would contain:

	   lib/HTML/FormFu/Constraint/MyApp/
	   lib/HTML/FormFu/Validator/MyApp/
	   lib/HTML/FormFu/Plugin/MyApp/
	   etc.

       Then, the form config file would just need:

	   validator: 'MyApp::SomeValidator'

       And the class would be something like this:

	   package HTML::FormFu::Validator::MyApp::SomeValidator;
	   use strict;
	   use warnings;
	   use base 'HTML::FormFu::Validator';

	   sub validate_value {
	       my ( $self, $value, $params ) = @_;

	       my $c = $self->form->stash->{context};

	       return 1 if $c->model('DBIC')->is_valid($value);

	       # assuming you want to return a custom error message
	       # which perhaps includes something retrieved from the model
	       # otherwise, just return 0
	       die HTML::FormFu::Exception::Validator->new({
		   message => 'custom error message',
	       });
	   }

	   1;

NAME

       Catalyst::Helper::HTML::FormFu - Helper to deploy HTML::FormFu template files.

SYNOPSIS

	   script/myapp_create.pl HTML::FormFu

DESCRIPTION

       As of version 0.02000, HTML::FormFu doesn't use the TT template files by default - it uses in internal rendering engine.

       If you don't want to customise the generated markup, you don't need to use Catalyst::Helper::HTML::FormFu at all.

       If you want to customise the generated markup, you'll need a local copy of the template files. To create the files in the default
       "root/formfu" directory, run:

	   script/myapp_create.pl HTML::FormFu

       To create the files in a different subdirectory of "root", pass the path as an argument. The following example would create the template
       files into the directory "root/forms".

	   script/myapp_create.pl HTML::FormFu forms

       You'll  also need to tell HTML::FormFu to use the TT renderer, this can be achieved with Catalyst::Controller::HTML::FormFu, with the
       following Catalyst application YAML config:

	   ---
	   'Controller::HTML::FormFu':
	     constructor:
	       render_method: tt
