How to use nested forms in Rails 3?

Question

I have a question on rails3 nested_form.
These are my two models:

class User
   belongs_to :shop
   accepts_nested_attributes_for :shop
end

class Shop
  has_many :users
end

In my register view(i am using Devise):

form_for(resourse,:url => registration(resource_name)) do  |f|
   =f.fields_for :shop do |s|
     =s.text_fields :name

but i get nothing for this form. What should i do?

You need to add some objects first to it. Use build method on model in controller.

Example:

@shop = Shop.new
3.times { @shop.users.build }

More informations at Railscasts. AJAX is used in second part of this video.
