This is an example from the geokit plugin which I am trying to reproduce.
class Location < ActiveRecord::Base belongs_to :locatable, :polymorphic => true acts_as_mappable end
class Company < ActiveRecord::Base has_one :location, :as => :locatable # also works for belongs_to associations acts_as_mappable :through => :location end
We see two separate models here. Now is there also a third model, like some kind of join table? Also is there a locatable_id:integer and locatable_type:string as well?
