Modelling Relationships as objects
DHH in Rails Confeerence pointed out that abstract relationships should be
converted into concrete objects, CRUDying up relationships.
An example would be
class User < ActiveRecord::Base
has_many :subscriptions
has_many :news_categories, :through => :subscriptions
end
class NewsCategory < ActiveRecord::Base
has_many :subscriptions
has_many :users, :through => :subscriptions
