Here's what I'm gathering that your models look like: class User < AR::Base has_many :favorites end class Favorite < AR::Base belongs_to :user belongs_to :favoritable, :polymorphic => true end class Post < AR::Base has_many :favorites, :as => :favoritable end In that case, you're looking for the :source_type option to has_many (on User): has_many :favorite_posts, :through => :favorites, :source => :favoritable, :source_type => 'Post' --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
