Create nested forms using Devise

I'm trying to build a nested form using Devise, keeping the devise featuring as sending an email when a new user signs up. I would like to have something like this:

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <%= f.fields_for(:information) do |info| %>

    <div><%= info.text_field :name, :placeholder => 'Nome' %></div>

    <div><%= info.text_field :surname, :placeholder => 'Cognome' %></div>

  <% end %>


  <div><%= f.email_field :email, :autofocus => true, :placeholder => 'E-mail' %></div>

  <div><%= f.password_field :password, :placeholder => 'Password' %></div>

  <div><%= f.password_field :password_confirmation, :placeholder => 'Conferma password' %></div>

  <div><%= f.submit "Registrati", class: "btn btn-large btn-info" %></div>
<% end %>

In my route.rb

devise_for :users, :controllers => { :registrations => "users" }

In my user.rb

class User < ActiveRecord::Base
  has_one :information, dependent: :destroy
  # Include default devise modules. Others available are:
  # :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable,
     :validatable, :confirmable, :lockable

  accepts_nested_attributes_for :information, update_only: true
end

and in information.rb

class Information < ActiveRecord::Base
  belongs_to :user
end

in users_controller.rb

class UsersController < Devise::RegistrationsController

  def new
super
resource.build_information
  end

end

But nothing happen, or better the 2 fields name and surname don't appear, but I don't receive an error message

Here is what I would do,

I would move this line from the controller to the view(fields_for takes 2 parameters). Like below,

Controller

def new
   super
   resource.build_information #remove from here
end

View

<!--Added here -->
<%= f.fields_for(:information,resource.build_information) do |info| %>

Must work now!

OR

Just change <%= form_for(resource, :as => res..... to

<%= form_for(@resource, :as => res

Note "@", this will work. Remove build_information both from view and controller.
