[Catalyst] Helper classes shared across multiple controllers - any recommendations?

Base classes.  Common code goes in a base class:

    package YourApp::BaseController::Foo;
    use base 'Catalyst::Controller';

    sub some_method {}
    sub some_action :Attributes Are OK {}

    1;

Then:

    package YourApp::Controller::Bar;
    use base 'YourApp::BaseController::Foo';
    # now you have some_method and some_action

Finally, use __PACKAGE__->config to your advantage. =


I have a good example of controller subclassing here:

   =

http://search.cpan.org/src/JROCKWAY/Catalyst-Model-Adaptor-0.01/t/lib/TestA=
pp/BaseController/Adaptor.pm

That base class is used in a few places:

   =

http://search.cpan.org/src/JROCKWAY/Catalyst-Model-Adaptor-0.01/t/lib/TestA=
pp/Controller/Adaptor.pm
   =

http://search.cpan.org/src/JROCKWAY/Catalyst-Model-Adaptor-0.01/t/lib/TestA=
pp/Controller/Factory.pm
   =

http://search.cpan.org/src/JROCKWAY/Catalyst-Model-Adaptor-0.01/t/lib/TestA=
pp/Controller/PerRequest.pm

Pretty nice, eh?
