SYNOPSISDESCRIPTIONMETHODSCORE VALIDATORSBEST 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;
