Question

是否可以在关注范围内使用Amoeba宝石？目前，当我尝试在一个关注点内运行它时，我收到此错误：

undefined method `amoeba' for Amoeba:Module

相同的代码在实际模型中运行良好，但我想干它，因为它在我的两个模型之间非常相似......这就是关注的样子：

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

变形虫是一种类方法。使用ActiveSupport :: Concern时，应在include block

中调用它

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

ActiveSupport::Concern

Rails 4，Amoeba Gem在一个关注点内
