Hello. Thanks in advance for your help. What is the slickest way of accessing children of children.

My understanding is that you can use "Parent.children" to get the children of an object, but Parent.children.children wont work (while Child.children will, but doesn't help)

Right now I'm using something like this

Here's where the language conventions of Rails (ActiveRecord) really shine. Re-read your explanation and then this possible solution:

class Challenge < ActiveRecord::Base    has_many :challengers, :dependent => :destroy    has_many :posts, :through => :challengers end

This assumes that: class Challenger < ActiveRecord::Base    belongs_to :challenge    has_many :posts end

class Post < ActiveRecord::Base    belongs_to :challenger end
