Rails 4，Amoeba寶石內的疑慮

Question

是否有可能在關注中使用Amoeba寶石？目前，當我嘗試運行它裏面關注我得到這個錯誤：

undefined method `amoeba' for Amoeba:Module 

相同的代碼工作的實際模型裏面很好，但我要幹它，因爲它是2之間高度相似的我模型...以下是關注的內容：

module Amoeba 
    extend ActiveSupport::Concern 

    amoeba do 
    enable 
    customize(lambda { |original, clone| 
     clone.uid  = SecureRandom.hex(2) 
     clone.activities = [] 

    if original.class.name == "Widget" 
     clone.bookings = [] 
    end 

    if orignal.class.name == "Flotsam" 
     clone.remaining = 100 
     if original.expiration.past? 
     clone.expiration = Date.today + 5.years 
     end 
    end 

    if original.icon.present? 
     clone.icon = original.icon 
    end 
    if original.pdf.present? 
     clone.pdf = original.pdf 
    end 
    }) 
end

amoeba是一種類方法。隨着的ActiveSupport ::關注它應該包括的塊中被調用

module Amoeba 
    extend ActiveSupport::Concern 
    included do 
    amoeba do 
    .... 
    end 
    end 

ActiveSupport::Concern
