NAME

Catalyst::Controller - Catalyst Controller base class

SYNOPSIS

   package MyApp::Controller::Search
   use base qw/Catalyst::Controller/;
 
   sub foo : Local {
     my ($self,$c,@args) = @_;
     ...
   } # Dispatches to /search/foo
 
 

DESCRIPTION

Controllers are where the actions in the Catalyst framework reside. Each action is represented by a function with an attribute to identify what kind of action it is. See the Catalyst::Dispatcher for more info about how Catalyst dispatches to actions.

CONFIGURATION

Like any other Catalyst::Component, controllers have a config hash, accessible through $self->config from the controller actions. Some settings are in use by the Catalyst framework:

namespace

This specifies the internal namespace the controller should be bound to. By default the controller is bound to the URI version of the controller name. For instance controller 'MyApp::Controller::Foo::Bar' will be bound to 'foo/bar'. The default Root controller is an example of setting namespace to '' (the null string).

path

Sets 'path_prefix', as described below.

METHODS

BUILDARGS ($app, @args)

From Catalyst::Component::ApplicationAttribute, stashes the application instance as $self->_application.

$self->action_for('name')

Returns the Catalyst::Action object (if any) for a given method name in this component.

$self->action_namespace($c)

Returns the private namespace for actions in this component. Defaults to a value from the controller name (for e.g. MyApp::Controller::Foo::Bar becomes ``foo/bar'') or can be overridden from the ``namespace'' config key.

$self->path_prefix($c)

Returns the default path prefix for :PathPrefix, :Local, :LocalRegex and relative :Path actions in this component. Defaults to the action_namespace or can be overridden from the ``path'' config key.

$self->register_actions($c)

Finds all applicable actions for this component, creates Catalyst::Action objects (using $self->create_action) for them and registers them with $c->dispatcher.

$self->get_action_methods()

Returns a list of Moose::Meta::Method objects, doing the MooseX::MethodAttributes::Role::Meta::Method role, which are the set of action methods for this package.

$self->register_action_methods($c, @methods)

Creates action objects for a set of action methods using " create_action ", and registers them with the dispatcher.

$self->create_action(%args)

Called with a hash of data to be use for construction of a new Catalyst::Action (or appropriate sub/alternative class) object.

$self->_application

$self->_app

Returns the application instance stored by "new()"
