I was wondering if you could help me with a quick question on writting
polymorphic join associations.
I have User has_many Favorite(polymorphic). The user has favorite
Posts and Favorite Comments.
I want set up a direct association on User to Post
class User < ActiveRecord::Base
has_many :favorite_posts , :as => :favoriteable, :source => :posts
end
I’m not quite sure how to describe that :favorite_posts association.
Right now, I’m just using a little method to bridge the gap, but would
prefer something more conventional, if possible.
Any help would be appreciated!
Thanks,

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’
