在模块中混合使用attr_accessible，has_one，has_many

Can I do somehting like this in Rails ?

我可以在Rails中做这样的事吗？

module Authored
  belongs_to :user
  attr_accessible creation_date
end

class Line < ActiveRecord::Base
  include Authored
end

class Document < ActiveRecord::Base
  include Authored
end

class User < ActiveRecord::Base
  has_many :creations, :class_name => 'Authored'
end

Or do I need to use simple inheritance, even if my Authored classes have different class hierarchies ?

或者我是否需要使用简单继承，即使我的Authored类具有不同的类层次结构？

module Authored
  extend ActiveSupport::Concern

  included do
    belongs_to :user
    attr_accessible :creation_date
  end
end

class Line < ActiveRecord::Base
  include Authored
end

class Document < ActiveRecord::Base
  include Authored
end
