Hi!
Are you using DBIx::Class, right? So, note that DBIC is a separate project and has its own ML (http://lists.scsys.co.uk/mailman/listinfo/dbix-class/).

You want to extend a resultset class with a custom method like:

package MyApp::Schema::ResultSet::Point;

use base 'DBIx::Class::ResultSet';

sub vertex {
    my $rs = shift;
    return $rs->search({ type => 'vertex' });
}

1;
