Introducing Catalyst::ActionRole::DetachOnDie
In my last post I introduced Catalyst::Controller::Accessors, which is mostly aimed at users who do a lot of chaining. This module is similarly targeted for chaining users. Anyone who has used chaining for more than a few weeks will know that exceptions in chains are stupid; an exception will not stop the chain, but merely end the current part of the chain, add to $c->errors, and run the next part of the chain. I would understand this if it were something that you could choose to turn on in a per-chain basis or something, but as a default it’s horrible.
This module solves that problem. It just detaches the chain and sets $c->errors when an exception is thrown. To use it you just need to do the following in your controllers (base controller anyone?):
package MyApp::Controller::Foo;
use Moose;
BEGIN { extends 'Catalyst::Controller::ActionRole' }
__PACKAGE__->config(
action_roles => ['DetachOnDie'],
);
...;
If for some reason you can’t use the excellent Catalyst::Controller::ActionRole you can use the ActionClass version as follows:
package MyApp::Controller::Foo;
use Moose;
BEGIN { extends 'Catalyst::Controller' }
__PACKAGE__->config(
action => {
'*' => { ActionClass => 'DetachOnDie' },
},
);
...;
