NAME

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

SYNOPSIS

       ResultSet:

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

        use parent '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 parent '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.

       If you did not call the "with_*" method on your ResultSet, and call the proxy method, it
       will transparently fallback and do the call and fetch the needed data. E.g.:

        my $foo = $schema->resultset('Foo')->first; ## did not call with_friend_count
        print $foo->friend_count; ## will produce desired result magically

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.
