Make you ActiveRecord model act as rateable.
class Model < ActiveRecord::Base
acts_as_rateable
end
Add a rating to a model instance
model = Model.new
rating = Rating.new(:rating => 1)
model.ratings << rating
Each rating references the rateable object
model = Model.find(1)
model.ratings.get(0).rateable == model
