NAME Catalyst::ActionRole::DetachOnDie - If something dies in a chain, stop the chain VERSION version 0.001001 SYNOPSIS package MyApp::Controller::Foo; use Moose; BEGIN { extends 'Catalyst::Controller::ActionRole' } __PACKAGE__->config( action => { '*' => { Does => 'DetachOnDie' }, }, ); ...; DESCRIPTION Chained dispatch is arguably one of the coolest features Catalyst has to offer, unfortunately it is marred by the bizarre decision to have exceptions thrown not detach a chain. To be clear, if one has a chain as follows: sub first : Chained('/') PathPart('') CaptureArgs(0) { ... } sub middle : Chained('first') PathPart('middle') CaptureArgs(0) { ... } sub last : Chained('middle') PathPart('') Args(0) { ... } If the URL /middle is dispatched to, but an exception is raised in the "middle" (or even "first") method, the "last" method will still run! This module solves that problem. I recommend you use it as I have documented in the "SYNOPSIS", as that will make it apply to all of your actions, but if for some reason you do not want to apply it to all actions you can apply it per action as follows: sub foo : Chained('bar') PathPart('') CaptureArgs(0) Does('DetachOnDie') { ... } If you do not want to use the action role, check out Catalyst::Action::DetachOnDie, which does the same thing but does not require the use of Catalyst::Controller::ActionRole.
