NAME

DBIx::Class::Helper::Row::ProxyResultSetUpdate - Efficiently reuse ResultSet updates from results

CONTENTS

SYNOPSIS

ResultSet:



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

 use parent DBIx::Class::ResultSet;

 sub update {
    my ($self, $data) = @_;

    die you fool! if $data->{name} eq fool;

    return $self->next::method($data);
 }



Result:



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

 use parent DBIx::Class::Core;

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

 ...



or with DBIx::Class::Candy:



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

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

 ...



DESCRIPTION

This module makes reusing resultset updates from a result trivially easy. Often the only way that people share update methods is by overriding update in their resultset to use update_all in DBIx::Class::ResultSet. Unfortunately, that can end up being wildly inefficient. Instead, if you can write your update in terms of the resultset, you can make your code much faster and more efficient.
