Hi,

See if
"http://search.cpan.org/~ash/DBIx-Class-0.08006/lib/DBIx/Class/Manual/Cookbook.pod#Predefined_searches"
can help you.  I've use this technique for anytime I
need a method against the resultset.

If you find this is helpful and discover that you need
lots of these kinds of classes, you should take a look
at:
http://search.cpan.org/~ash/DBIx-Class-0.08006/lib/DBIx/Class/Schema.pm#load_namespaces

Which is a neat way to create 'drop' points for
resultset classes.  At least I think so.
