ruby-on-rails - 您如何需要活动模型关联？

Question

我正在尝试在没有 Rails 的情况下使用 Active Model Associations...我需要它吗？

require 'active_model'
require 'activemodel-associations'

class Base
  include ActiveModel::Model
  include ActiveModel::Associations

end

 `require': cannot load such file -- activemodel-associations
