Name

Catalyst::Plugin::ConfigComponents - Creates components from config entries

Synopsis

   # In your Catalyst application
   package YourApp;

   use Catalyst qw(ConfigComponents);

   __PACKAGE__->setup;

   # In your applications config file
   <component name="Model::YourModel">
      <parent_classes>YourExternal::ModelE<lt>/parent_classes>
      <parent_classes>Catalyst::ModelE<lt>/parent_classes>
   </component>

   # Do not create YourApp::Model::YourModel this module will do it for you

   # In a controller this will call your_method in
   # the class YourExternal::Model
   $result = $c->model( q(YourModel) )->your_method( ... );

Version

This documents version v0.9.$Rev: 1 $ of Catalyst::Plugin::ConfigComponents

Description

When the application starts this module creates Catalyst component class definitions using config information. The defined class inherits from the list of parent classes referenced in the config file

Configuration and Environment

Specify a Plugin::ConfigComponents config option. Attributes are

component_active

If the component_active config attribute exists and is false the component will not be loaded

parent_classes

List of classes for the derived component to inherit from

search_extra

To add additional search paths, specify a key named search_extra as an array reference. Items in the array beginning with :: will have the application class name prepended to them

setup_method

Defaults to _setup_config_components, the method to call after the call to Catalyst::setup_components

Subroutines/Methods

setup_components

Calls the setup method (which defaults to "setup_config_components") after the parent method

_setup_config_components

For each config key matching \A Model|View|Controller :: it checks if the corresponding component already exists, and if it doesn't this method creates it at run-time

The parent class is set to MyApp->config->{ $component }->{parent_classes} if it exists, Catalyst::$component otherwise. The parent_classes can be an array ref in which case the defined class will inherit from all classes in the list (multiple inheritance)

This code was originally posted to the Catalyst mailing list by Dagfinn Ilmari Manns�ker as a patch in response to an idea by Castaway. I thought it would be better as a plugin and have extended it to handle MI
