Add foreign_type option for polymorphic has_one and has_many. To be possible to use a custom column name to save/read the polymorphic associated type in a has_many or has_one polymorphic association, now users can use the option :foreign_type to inform in what column the associated object type will be saved. 2014-12-08 19:43:16 +00:00			`class Image < ActiveRecord::Base`
