NAME

DBIx::Class::Candy::ResultSet - Sugar for your resultsets

SYNOPSIS

 package MyApp::Schema::ResultSet::Artist;

 use DBIx::Class::Candy::ResultSet
   -components => ['Helper::ResultSet::Me'];

 use experimental 'signatures';

 sub by_name ($self, $name) { $self->search({ $self->me . 'name' => $name }) }

 1;

DESCRIPTION

DBIx::Class::Candy::ResultSet is an initial sugar layer in the spirit of DBIx::Class::Candy. Unlike the original it does not define a DSL, though I do have plans for that in the future. For now all it does is set some imports:

  • turns on strict and warnings

  • sets your parent class

  • sets your mro to c3

IMPORT OPTIONS

See "SETTING DEFAULT IMPORT OPTIONS" for information on setting these schema wide.

-base

 use DBIx::Class::Candy::ResultSet -base => 'MyApp::Schema::ResultSet';

The first thing you can do to customize your usage of DBIx::Class::Candy::ResultSet is change the parent class. Do that by using the -base import option.

-components

 use DBIx::Class::Candy::ResultSet -components => ['Helper::ResultSet::Me'];

DBIx::Class::Candy::ResultSet allows you to set which components you are using at import time.

-perl5

 use DBIx::Class::Candy::ResultSet -perl5 => v20;

I love the new features in Perl 5.20, so I felt that it would be nice to remove the boiler plate of doing use feature ':5.20' and add it to my sugar importer. Feel free not to use this.

SETTING DEFAULT IMPORT OPTIONS

Eventually you will get tired of writing the following in every single one of your resultsets:

 use DBIx::Class::Candy::ResultSet
   -base      => 'MyApp::Schema::ResultSet',
   -perl5     => v20,
   -experimental => ['signatures'];

You can set all of these for your whole schema if you define your own Candy::ResultSet subclass as follows:

 package MyApp::Schema::Candy::ResultSet;

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

 sub base { $_[1] || 'MyApp::Schema::ResultSEt' }
 sub perl_version { 20 }
 sub experimental { ['signatures'] }

Note the $_[1] || in base. All of these methods are passed the values passed in from the arguments to the subclass, so you can either throw them away, honor them, die on usage, or whatever. To be clear, if you define your subclass, and someone uses it as follows:

 use MyApp::Schema::Candy::ResultSet
    -base => 'MyApp::Schema::ResultSet',
    -perl5 => v18,
   -experimental => ['postderef'];

Your base method will get MyApp::Schema::ResultSet, your experimental will get ['postderef'], and your perl_version will get 18.
