Nested Resources Issues

I have the following in my routes file:

resources :users, :path => 'ronin' do
     resources :notes, :path => 'moras'
     resources :collections, :path => 'haiku'
   end

If use user.collections I get all the collections owned by the user.
How ever if use user.notes I get

NoMethodError: undefined method `notes' for

What am I missing here?

Forgot to add has_many :notes in my user model.
