NAME
       DBIx::Class::Helper::Row::ProxyResultSetMethod - Efficiently reuse ResultSet methods from results

VERSION
       version 2.013002

SYNOPSIS
       ResultSet:

	package MyApp::Schema::ResultSet::Foo;

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

	__PACKAGE__->load_components(qw(
	   Helper::ResultSet::CorrelateRelationship
	));

	...;

	sub with_friend_count {
	   shift->search(undef, {
	      '+columns' => {
		 'friend_count' => $self->correlate('friends')->count_rs->as_query,
	      },
	   })
	}

       Result:

	package MyApp::Schema::Result::Foo;

	use base 'DBIx::Class::Core';

	__PACKAGE__->load_components(qw( Helper::Row::ProxyResultSetMethod ));

	__PACKAGE__->proxy_resultset_method('friend_count');

       or with DBIx::Class::Candy:

	package MyApp::Schema::Result::Foo;

	use DBIx::Class::Candy -components => ['Helper::Row::ProxyResultSetMethod'];

	proxy_resultset_method 'friend_count';

       Elsewhere:

	my $row = $foo_rs->first;
	say $row->friend_count . ' friends';

DESCRIPTION
       This module makes reusing resultset methods from a result trivially easy.  You should be using it.

METHODS
   proxy_resultset_method
	__PACKAGE__->proxy_resultset_method( $name => {
	   slot 	    => $slot,
	   resultset_method => $rs_method
	});

       "proxy_resultset_method"'s first argument is the name of the method to generate and is required.  The other two arguments, $slot, and
       $resultset_method are optional.	If unspecified $slot will default to $name and $resultset_method will default to "with_$name".	$slot is
       the column that the data being retrieved is stored as in the ResultSet method being proxied to.	$resultset_method is (duh) the ResultSet
       method being proxied to.

CANDY EXPORTS
       If used in conjunction with DBIx::Class::Candy this component will export:

       proxy_resultset_method

DEDICATION
       This module is dedicated to Ray Bradbury, who wrote Something Wicked This Way Comes, Dandelion Wine, and numerous short stories, plays, etc
       etc.  Read this author's books.
