 There are rares cases when the template doesn't map directly to any object. In these cases, you can set data to false or skip data declaration altogether.

 Rabl allow you to define easily your templates, even with hierarchy of 2 or 3 levels. Let's suppose your have a `thread` model that has many `posts` and that each post has many `comments`. We can display a full thread in a few lines
 
 ```ruby
-	object :@thread
-	attribute :caption

+attribute :caption
+child :posts do
 	attribute :title
