This was my solution for a polymorphic many-to-many association

class ItemCountry < ActiveRecord::Base
  belongs_to :locatable, :polymorphic => true
  belongs_to :country
  # fields are :locatable_id, :locatable_type, :country_id
end

class Title < ActiveRecord::Base

has_many :countries, :through => :item_countries, :as => :locatable
