default_scope and associations

Question

Suppose I have a Post model, and a Comment model. Using a common pattern, Post has_many Comments.

If Comment has a default_scope set:

default_scope w         


        

Answer 1

class Comment
  def post_comments(post_id)
    with_exclusive_scope { find(all, :conditions => {:post_id => post_id}) }
  end
end

Comment.post_comments(Post.first.id)
