A very simple gem. This allows you to use the following code in ActiveRecord.

“by class PlanSku < ActiveRecord::Base belongs_to :sku belongs_to :plan_cost belogns_to :plan_coverage

build_associated :sku
build_associated :plan_cost
build_associated :plan_coverage

end

plan = PlanSku.new plan.sku # Instead of nil, it now returns PlanSku.build_sku

“

Tested on Rails3.1. Use at own risk.
