I have two models, Article and Post, that has many Comments. However, both Article and Post are inherited from a BaseContent class like so: class Article < BaseContent has_many :comments, :as => :commentable end class Post < BaseContent has_many :comments, :as => :commentable end and here''s my Comment model: class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true end Now when I try to associate a comment with an Article or Post, the commentable_type field gets set as "BaseContent" instead of "Article" or "Post." Is there a way to specify what the commentable_type field is? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m just doing: comment = Comment.New() # set comment properties here comment.save Post.comments << comment On Oct 29, 1:35 pm, reHa <pres...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On Oct 29, 3:31 pm, et <erict...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > > > I have two models, Article and Post, that has many Comments.

Have you tried this way? It worked for me: comment = Comment.New() comment.commentable = post #instance of the actual post you are commenting # set comment properties here comment.save> I''m just doing: > > comment = Comment.New() > # set comment properties here > comment.save > Post.comments << comment--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That still saves the comment as commentable_id = 1, commentable_type BaseContent. So when I save a comment for Article with id 1 and another comment for Post with id 1, there now are two comments with commentable_id = 1, commentable_type = BaseContent and they both show up with I do Article.find(1).comments and Post.find(1).comments On Oct 29, 2:21 pm, reHa <pres...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Have you tried this way? > > It worked for me: > > comment = Comment.New() > comment.commentable = post #instance of the actual post you are > commenting > # set comment properties here > comment.save > > > I''m just doing: > > > comment = Comment.New() > > # set comment properties here > > comment.save > > Post.comments << comment--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I forgot about the problems with STI
you would have to define commentable_type method in BaseContent as
said in the: activerecord/lib/active_record/associations.rb
# Using polymorphic associations in combination with single table
inheritance (STI) is a little tricky. In order
# for the associations to work as expected, ensure that you store
the base model for the STI models in the
# type column of the polymorphic association. To continue with the
asset example above, suppose there are guest posts
# and member posts that use the posts table for STI. In this case,
there must be a +type+ column in the posts table.
#
# class Asset < ActiveRecord::Base
# belongs_to :attachable, :polymorphic => true
#
# def attachable_type=(sType)
# super(sType.to_s.classify.constantize.base_class.to_s)
# end
# end
#
# class Post < ActiveRecord::Base
# # because we store "Post" in attachable_type now :dependent
=> :destroy will work
# has_many :assets, :as => :attachable, :dependent => :destroy
# end
#
# class GuestPost < Post
# end
#
# class MemberPost < Post
# end
#
