note tospo <h1>Using Moose Roles in ResultSet Classes</h1> turns out that this is a bit more tricky and needs some more magic. Thanks to the folks over on irc I found out that you need to fiddle with the BUILDARGS to make it work. So, the above code works for <b>Result</b> classes, while the following will enable Moose in your <b>ResultSet</b> classes: <code> package MyApp::Schema::ResultSet::Foo; use strict; use warnings; use Moose; use MooseX::NonMoose; use MooseX::MarkAsMethods autoclean => 1; extends 'DBIx::Class::ResultSet'; with 'SomeOldRole'; # insert your Role here... # This is the crucial bit - don't ask.... sub BUILDARGS { $_[2] } ### your ResultSet methods here ### __PACKAGE__->meta->make_immutable; 1; </code> 968402 968402
