CatalystX::Component::Traits3pm

Usage

    package Catalyst::Model::SomeModel;
    with 'CatalystX::Component::Traits';
    package MyApp::Model::MyModel;
    use parent 'Catalyst::Model::SomeModel';
    package MyApp;
    __PACKAGE__->config('Model::MyModel' => {
        traits => ['SearchedForTrait', '+Fully::Qualified::Trait']
    });

Overview

Adds a "COMPONENT" in Catalyst::Component method to your Catalyst component base class that reads the optional "traits" parameter from app and component config and instantiates the component subclass with those traits using "new_with_traits" in MooseX::Traits from MooseX::Traits::Pluggable.

Trait search

Trait names qualified with a "+" are taken to be full package names.

Unqualified names are searched for, using the algorithm described below.

    MyApp::Model::MyModel
    Catalyst::Model::CatModel
    Catalyst::Model
    Catalyst::Component
    Moose::Object

    traits => ['Foo']

    MyApp::TraitFor::Model::CatModel::Foo
    Catalyst::TraitFor::Model::CatModel::Foo

    My::App::Controller::AController
    CatalystX::Something::ControllerBase::SomeController
    Catalyst::Controller
    Catalyst::Model
    Catalyst::Component
    Moose::Object

    traits => ['Foo']

    My::App::TraitFor::Controller::SomeController::Foo
    CatalystX::Something::TraitFor::Controller::SomeController::Foo

Trait merging

Traits from component class config and app config are automatically merged if you set the "_trait_merge" attribute default, e.g.:

    has '+_trait_merge' => (default => 1);

You can remove component class config traits by prefixing their names with a "-" in the app config traits.

For example:

    package Catalyst::Model::Foo;
    has '+_trait_merge' => (default => 1);
    __PACKAGE__->config->{traits} = [qw/Foo Bar/];
    package MyApp;
    __PACKAGE__->config->{'Model::Foo'}{traits} = [qw/-Foo Baz/];

Will load the traits:

    Bar Baz
