NAME

       HTML::FormFu::Constraint::_others - Base class for constraints needing others() method

METHODS

   others
       Arguments: @nested_names

   other_siblings
       Arguments: $bool

       If true, the "others" list will be automatically generated from the "nested_name" of all fields which are considered siblings of the field
       the constraint is attached to.

       Sibling are found by searching up through the field's parental hierarchy for the first block containing any other field. All fields
       attached at any depth to this block are considered siblings.

   attach_errors_to_base
       If true, any error will cause the error message to be associated with the field the constraint is attached to.

       Can be use in conjunction with "attach_errors_to_others".

       Is ignored if "attach_errors_to" is set.

   attach_errors_to_others
       If true, any error will cause the error message to be associated with every field named in "others".

       Can be use in conjunction with "attach_errors_to_base".

       Is ignored if "attach_errors_to" is set.

   attach_errors_to
       Arguments: @field_names

       Any error will cause the error message to be associated with every field named in "attach_errors_to".

       Overrides "attach_errors_to_base" and "attach_errors_to_others".

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;
