= 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.
