class User < ActiveRecord::Base
end

module Foo
  class User
  end
end

module Foo
  class DoesSomethingWithActiveRecordUser
    def initialize user_id
      User.find(user_id)
    end
  end
end

如果我调用Foo :: DoesSomethingWithActiveRecordUser.new(1)我收到一条错误消息,上面写着Foo :: User的未定义方法’find’.

如何在Foo中调用ActiveRecord用户？

谢谢.
