NAME

6       DBIx::Class::Helper::Row::ProxyResultSetMethod - Efficiently reuse
7       ResultSet methods from results with fallback
8

SYNOPSIS

10       ResultSet:
11
12        package MyApp::Schema::ResultSet::Foo;
13
14        use parent 'DBIx::Class::ResultSet';
15
16        __PACKAGE__->load_components(qw(
17           Helper::ResultSet::CorrelateRelationship
18        ));
19
20        ...;
21
22        sub with_friend_count {
23           shift->search(undef, {
24              '+columns' => {
25                 'friend_count' => $self->correlate('friends')->count_rs->as_query,
26              },
27           })
28        }
29
30       Result:
31
32        package MyApp::Schema::Result::Foo;
33
34        use parent 'DBIx::Class::Core';
35
36        __PACKAGE__->load_components(qw( Helper::Row::ProxyResultSetMethod ));
37
38        __PACKAGE__->proxy_resultset_method('friend_count');
39
40       or with DBIx::Class::Candy:
41
42        package MyApp::Schema::Result::Foo;
43
44        use DBIx::Class::Candy -components => ['Helper::Row::ProxyResultSetMethod'];
45
46        proxy_resultset_method 'friend_count';
47
48       Elsewhere:
49
50        my $row = $foo_rs->first;
51        say $row->friend_count . ' friends';
52

DESCRIPTION

54       This module makes reusing resultset methods from a result trivially
55       easy.  You should be using it.
56

METHODS

58   proxy_resultset_method
59        __PACKAGE__->proxy_resultset_method( $name => {
60           slot             => $slot,
61           resultset_method => $rs_method
62        });
63
64       "proxy_resultset_method"'s first argument is the name of the method to
65       generate and is required.  The other two arguments, $slot, and
66       $resultset_method are optional.  If unspecified $slot will default to
67       $name and $resultset_method will default to "with_$name".  $slot is the
68       column that the data being retrieved is stored as in the ResultSet
69       method being proxied to.  $resultset_method is (duh) the ResultSet
70       method being proxied to.
71
72       If you did not call the "with_*" method on your ResultSet, and call the
73       proxy method, it will transparently fallback and do the call and fetch
74       the needed data. E.g.:
75
76        my $foo = $schema->resultset('Foo')->first; ## did not call with_friend_count
77        print $foo->friend_count; ## will produce desired result magically
78

CANDY EXPORTS

80       If used in conjunction with DBIx::Class::Candy this component will
81       export:
82
83       proxy_resultset_method
84

DEDICATION

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