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.
