如何爲具有嵌套屬性的模型編寫工廠？

Question

在我的種子文件，我沿着線的東西：

Product.create([ 
    { 

    :description => "something something", 
    :goals => 
      [ 
      Goal.find_by_name("Healthy Living"), 
      Goal.find_by_name("Build Muscle") 
      ], 
    :variations_attributes => 
      [ 
       { 
       :flavor => Flavor.find_by_flavor("Vanilla"), 
       :price => 49.99, 
       }, 
       { 
       :flavor => Flavor.find_by_flavor("Chocolate"), 
       :price => 29.99, 
       } 
      ] 

    }]) 

我我會去建廠模仿這個紀錄？我在github上爲「工廠女孩」閱讀了「入門」讀物，但我仍然無法創造出像這樣的更高級工廠。任何幫助，將不勝感激。謝謝。

的產品型號是這樣的：

class Product < ActiveRecord::Base 
    attr_accessible :active, :goal_id, :description, :gender_id, :name, :internal_product_id, :image, :image_cache, :brand, :variations 
    attr_protected nil 

    belongs_to :gender 
    has_many :variations, :dependent => :destroy 
    has_many :product_goals 
    has_many :goals, :through => :product_goals 

    accepts_nested_attributes_for :variations, :reject_if => lambda { |a| a[:price].blank? }, :allow_destroy => true 

    mount_uploader :image, ImageUploader 

    def flavors 
    # return the set of available flavors 
    # this method is necessary because flavors are associated 
    # with variations, not the product itself 
    self.variations.collect{|v| v.flavor}.uniq.sort_by{|f| f.flavor} 
    end 


end

可以在工廠其他有效廠地址。像這樣：

after(:create) { |product| product.variations << FactoryGirl.create(:flavor) } 
after(:create) { |product| product.goals << FactoryGirl.create(:goal) }
