NAME

Catalyst::Plugin::SpecialAction::Trail - Support for the 'trail' special action

VERSION

Version 0.01

SYNOPSIS

  # enabling the 'trail' special action in a single controller:

  package MyApp::Controller::Foo;

  use Moose;
  use namespace::autoclean;

  extends 'Catalyst::Controller';

  with 'Catalyst::TraitFor::Controller::SpecialAction::Trail';

  sub trail : Private {
    my ($self, $c, @args) = (shift, shift, @_);

    ...
  }

  # globally enabling the 'trail' special action:

  package MyApp;

  use Moose;
  use namespace::autoclean;

  extends 'Catalyst';

  __PACKAGE__->setup(qw/ SpecialAction::Trail /);

  # now you can use 'trail' in any controller in your app

DISCLAIMER

This is ALPHA SOFTWARE. Use at your own risk. Features may change.

DESCRIPTION

This module introduces a new special action trail that unites the features of end and auto special actions (see "Built-in special actions" in Catalyst::Manual::Intro):

  • Like end, the trail actions will be run at the end of the request, after all URL-matching actions are called; but they are called before any end is run.

  • Like auto, multiple trail actions will be run in turn, starting with the application class and going through to the most specific controller class, and the processing chain stops if any of them returns false (any remaining trail actions are skipped and the control goes to end if there's any).

METHODS

setup_component

Overridden (with an 'around' method modifier) from "setup_component" in Catalyst. Applies the Catalyst::TraitFor::Controller::SpecialAction::Trail role to the Catalyst::Controller instance.

SEE ALSO

Catalyst, Catalyst::Manual::Intro.
