Consider a class:
class Link < ActiveRecord::Base
has_many :link_votes, :as => :vote_subject, :class_name => 'Vote'
has_many :spam_votes, :as => :vote_subject, :class_name => 'Vote'
end
The problem is, when I'm adding a new vote with @link.link_votes << Vote.new the vote_subject_type is 'Link', while I wish it could be 'link_votes' or something like that. Is this an AR limitation or is there a way to workaround this thing?
I've actually found one related answer, but I'm not quite sure about what it says: http://stackoverflow.com/questions/1168047/polymorphic-association-with-multiple-associations-on-the-same-model/1764117#1764117
