NAME

Form::Factory::Feature::Role::BuildAttribute - control features that modify the action attribute

VERSION

version 0.009

SYNOPSIS

package MyApp::Feature::AddPredicate;
our $VERSION = '0.009';


use Moose;

with qw(
    Form::Factory::Feature
    Form::Factory::Feature::Role::BuildAttribute
    Form::Factory::Feature::Role::Control
);

sub build_attribute {
    my ($class, $options, $meta, $name, $attr) = @_;
    $attr->{predicate} = 'has_' . $name;
}

package Form::Factory::Feature::Control::Custom::AddPredicate;
our $VERSION = '0.009';


sub register_implementation { 'MyApp::Feature::FillFromRecord' }

DESCRIPTION

Control features that implement this role are given the opportunity to directly modify the action attribute just before it is added to the meta-class.

This is done by implementing the build_attribute class method. This method will be passed a hash representing the feature arguments for this feature (since the feature will not yet exist as an object). It will then be passed the meta-class object, the name of the attribute being added, and a normalized hash of attribute parameters.

You may use these arguments to manipulate the attribute before it is created, create additional attributes, etc.
