NAME

       DBIx::Class::Helper::Row::SubClass - Convenient subclassing with DBIx::Class

VERSION

       version 2.013002

SYNOPSIS

	# define parent class
	package ParentSchema::Result::Bar;

	use strict;
	use warnings;

	use parent 'DBIx::Class';

	__PACKAGE__->load_components('Core');

	__PACKAGE__->table('Bar');

	__PACKAGE__->add_columns(qw/ id foo_id /);

	__PACKAGE__->set_primary_key('id');

	__PACKAGE__->belongs_to( foo => 'ParentSchema::Result::Foo', 'foo_id' );

	# define subclass
	package MySchema::Result::Bar;

	use strict;
	use warnings;

	use parent 'ParentSchema::Result::Bar';

	__PACKAGE__->load_components(qw{Helper::Row::SubClass Core});

	__PACKAGE__->subclass;

       or with DBIx::Class::Candy:

	# define subclass
	package MySchema::Result::Bar;

	use DBIx::Class::Candy
	   -base => 'ParentSchema::Result::Bar',
	   -components => ['Helper::Row::SubClass'];

	subclass;

DESCRIPTION

       This component is to allow simple subclassing of DBIx::Class Result classes.

METHODS

   subclass
       This is probably the method you want.  You call this in your child class and it imports the definitions from the parent into itself.

   generate_relationships
       This is where the cool stuff happens.  This assumes that the namespace is laid out in the recommended "MyApp::Schema::Result::Foo" format.
       If the parent has "Parent::Schema::Result::Foo" related to "Parent::Schema::Result::Bar", and you inherit from
       "Parent::Schema::Result::Foo" in "MyApp::Schema::Result::Foo", you will automatically get the relationship to "MyApp::Schema::Result::Bar".

   set_table
       This is a super basic method that just sets the current classes' table to the parent classes' table.

CANDY EXPORTS

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

       join_table
       subclass
       generate_relationships
       set_table

NOTE

       This Component is mostly aimed at those who want to subclass parts of a schema, maybe for sharing a login system in a few different
       projects.  Do not confuse it with DBIx::Class::DynamicSubclass, which solves an entirely different problem.  DBIx::Class::DynamicSubclass
       is for when you want to store a few very similar classes in the same table (Employee, Person, Boss, etc) whereas this component is merely
       for reusing an existing schema.
