NAME

Catalyst::Controller::ActionRole - Apply roles to action instances

VERSION

version 0.05

SYNOPSIS

    package MyApp::Controller::Foo;

    use parent qw/Catalyst::Controller::ActionRole/;

    sub bar : Local Does('Moo') { ... }

DESCRIPTION

This module allows to apply roles to the Catalyst::Actions for different controller methods.

For that a Does attribute is provided. That attribute takes an argument, that determines the role, which is going to be applied. If that argument is prefixed with +, it is assumed to be the full name of the role. If it's prefixed with ~, the name of your application followed by ::Action::Role:: is prepended. If it isn't prefixed with + or ~, the value of the _action_role_prefix attribute will be prepended.

Additionally it's possible to to apply roles to all actions of a controller without specifying the Does keyword in every action definition:

    package MyApp::Controller::Bar

    use parent qw/Catalyst::Controller::ActionRole/;

    __PACKAGE__->config(
        action_roles => ['Foo', '~Bar'],
    );

    sub moo : Local { ... } # has Catalyst::Action::Role::Foo and MyApp::Action::Role::Bar applied

ATTRIBUTES

_action_role_prefix

This class attribute stores a string that is going to be prepended to all role names if they aren't prefixed with + or ~. It defaults to Catalyst::Action::Role::.

_action_roles

This attribute stores an array reference of role names that will be applied to every action of this controller. It can be set by passing a action_roles argument to the constructor. The same expansions as for Does will be performed.
