I'm trying to refactor some code to eliminate duplication, and am having trouble figuring out how to pass a config variable up to the superclass. I assume this should be simple....

My duplicated method is a 'begin()' that I'm overriding in order to set some specific logging functionality. Right now, it looks like this:

package MyApp::Foo;
use namespace::autoclean;
use Moose;
# ...

BEGIN { extends MyApp::Utilities; }

# override begin method (fr Catalyst::Action::Deserialize) to access l
+og stuff
sub begin : Private {
     my ($self, $c) = @_;
     my $logfile = $c->config->{ 'foo_logfile'}; # This is stored in e
+xternal config file; name isn't predictable

     my $log = Log::Dispatch->new(
     outputs => [
         [ 'File', min_level => 'debug', mode => '>>', newline => 1, f
+ilename => $logfile ],
     ],
     );
     $c->stash->{log_object} = $log;

     $c->forward('deserialize'); # ultimately goes to our callback
 }
sub deserialize : ActionClass('Deserialize') {}

All I want to do is move this into 'MyApp::Utilities', which already contains some generic stuff. The only thing that differs for each subclass is the name of the logfile. But I can't figure out how to tell the superclass this name. If I try '__PACKAGE__->config( logfile => 'foo_logfile' );' that fails because the 'extends' is called before this is read. If I try to move the '__PACKAGE__->config' into the 'BEGIN' block, that fails because it doesn't know about 'config()' at this point. What's my solution?
