ActiveModel include_root_in_json

I am a bit confused by this option... which can be found in the example below

 user = User.find(1)
  user.as_json
  # => { "user": {"id": 1, "name": "Konata Izumi", "age": 16,
                  "created_at": "2006/08/01", "awesome": true} }

  ActiveRecord::Base.include_root_in_json = false
  user.as_json
  # => {"id": 1, "name": "Konata Izumi", "age": 16,
        "created_at": "2006/08/01", "awesome": true}

http://rubydoc.info/gems/activemodel/3.1.3/ActiveModel/Serializers/JSON

Why does ActiveModel require you to use ActiveRecord to tell it that you dont want base objects in the root of your serialized objects?

I cannot seem to get this to work, currently I am doing:

require "active_model"
ActiveRecord::Base.include_root_in_json = false

But it just says that it cannot find the constant "ActiveRecord", which makes sense, but is this just a typo in the docs or is there some real reason for this? as ActiveRecord seems to deal with data storage concerns, ActiveModel seems to deal with augmenting simple models...

Hmm... Rails source for active model has the same example. Where are you trying to use it? In my ActiveModels I normally do: 

class Foo
  include ActiveModel::Serializers::JSON

  # ... more includes

  self.include_root_in_json = false

  # ... model stuff
end
