Hi to all, This is my first post here, I would first like to salute you all and praise the great work you guys are doing on RoR.
There is a patch (http://dev.rubyonrails.org/ticket/6461) sitting for quite a while on the Trac for nested has_many :through associations. I think it is a must and I have seen it requested quite a few times (http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/ 4517fb8bf464921a/6f4c544fb948b9d1 and http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/1ee28a00febcbc42/b34f05aae9e01688 ). The patch seems to be all sorted out for more than 2 months (all tests working). It was even made into a plugin by the author. Is there a reason it was not applied yet? I didn't find anything about it in this list or elsewhere. I think it greatly simplifies apps that have complex (=large number) models. To make a case for it, I will show a simple 'posts and comments' example where it would be very useful (I am just writing the essential). class CommentRating < AR:Base belongs_to :comment belongs_to :user end class Comment < AR::Base has_many :comment_ratings belongs_to :user end class Post < AR::Base has_many :comments belongs_to :user end class User < AR::Base has_many :posts has_many :comments, :through=>:posts has_many :comment_ratings, :through=>:comments end If I wanted to allow a user to review only the ratings given to the comments from his posts, I could use the contextualized finder: current_user.comment_ratings.find(params[:id]) I know this example seems a little "forced", but as your modelspace gets larger, without this kind of nesting, you find yourself having to write more and more custom finders, with joins, scopes, etc, for things that could be handled in a much simpler way.
