NAME
HTML::FormFu::Validator - Validator Base Class

VERSION
version 2.07

SYNOPSIS

DESCRIPTION

METHODS

CORE VALIDATORS

HTML::FormFu::Validator::Callback

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 Moose;
    extends '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;
