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;
