NAME

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

VERSION

version 1.093501

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::SubClass Core});

__PACKAGE__->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.
