SYNOPSIS

DESCRIPTION

METHODS

CORE VALIDATORS

BEST PRACTICES

13       Try to avoid using callbacks if possible. Below is a more maintainable
14       and reusable approach, which also keeps the code out of the controller.
15
16       A normal application's directory would contain:
17
18           lib/HTML/FormFu/Constraint/MyApp/
19           lib/HTML/FormFu/Validator/MyApp/
20           lib/HTML/FormFu/Plugin/MyApp/
21           etc.
22
23       Then, the form config file would just need:
24
25           validator: 'MyApp::SomeValidator'
26
27       And the class would be something like this:
28
29           package HTML::FormFu::Validator::MyApp::SomeValidator;
30           use strict;
31           use warnings;
32           use base 'HTML::FormFu::Validator';
33
34           sub validate_value {
35               my ( $self, $value, $params ) = @_;
36
37               my $c = $self->form->stash->{context};
38
39               return 1 if $c->model('DBIC')->is_valid($value);
40
41               # assuming you want to return a custom error message
42               # which perhaps includes something retrieved from the model
43               # otherwise, just return 0
44               die HTML::FormFu::Exception::Validator->new({
45                   message => 'custom error message',
46               });
47           }
48
49           1;
50
51       HTML::FormFu::Validator::Callback
