SYNOPSIS

15       HTML::FormFu::Validator::Callback
16

BEST PRACTICES
18       Try to avoid using callbacks if possible. Below is a more maintainable
19       and reusable approach, which also keeps the code out of the controller.
20
21       A normal application's directory would contain:
22
23           lib/HTML/FormFu/Constraint/MyApp/
24           lib/HTML/FormFu/Validator/MyApp/
25           lib/HTML/FormFu/Plugin/MyApp/
26           etc.
27
28       Then, the form config file would just need:
29
30           validator: 'MyApp::SomeValidator'
31
32       And the class would be something like this:
33
34           package HTML::FormFu::Validator::MyApp::SomeValidator;
35
36           use Moose;
37           extends 'HTML::FormFu::Validator';
38
39           sub validate_value {
40               my ( $self, $value, $params ) = @_;
41
42               my $c = $self->form->stash->{context};
43
44               return 1 if $c->model('DBIC')->is_valid($value);
45
46               # assuming you want to return a custom error message
47               # which perhaps includes something retrieved from the model
48               # otherwise, just return 0
49               die HTML::FormFu::Exception::Validator->new({
50                   message => 'custom error message',
51               });
52           }
53
54           1;
