Почему не работает Ruby on Rails fields_for?

Question

[Ivan Nesterovich]

Есть 3 модели: Товары, Заказы, Связывающая модель
Product:

has_many :purchaseds, :dependent => :destroy
has_many :orders, :through => :purchaseds

Order

has_many :purchaseds, :dependent => :destroy
has_many :products, through: :purchaseds
accepts_nested_attributes_for :purchaseds

Purchased

belongs_to :product
belongs_to :order

В контролере пишу:

@order = Order.new()
@products.each do |p|
   @order.purchaseds.build({
        :product_id => p.id
   })
end

В итоге в форме у меня пусто!

= form_for(@order) do |f|
  - f.fields_for :purchaseds do |p|
     = debug p

= debug @order.purchaseds выводит массив объектов как положено.

= form_for(@order) do |f|
  = f.fields_for :purchaseds do |p|
     = debug p
