= Composite Primary Keys for ActiveRecords
== Summary
ActiveRecords/Rails famously doesn't support composite primary keys. This RubyGem extends the activerecord gem to provide CPK support.
== Installation
gem install composite_primary_keys
== Usage
require 'composite_primary_keys'
class ProductVariation
set_primary_keys :product_id, :variation_seq
end
pv = ProductVariation.find(345, 12)
It even supports composite foreign keys for associations.
