ruby-on-rails - 如何从记录数组中获取属性哈希数组？

Question

我想打印所有问题和状态字段。如何在数组中提取所需的数据？

这是我的数组：@category_questions

[#<Question id: 38, user_id: 1, question: "hi", question_status: 1, created_at: "2013-06-04 18:32:28", updated_at: "2013-06-04 18:32:28">, #<Question id: 40, user_id: 1, question: "urll", question_status: 1, created_at: "2013-06-04 18:34:57", updated_at: "2013-06-04 18:34:57">, #<Question id: 41, user_id: 1, question: "urll", question_status: 1, created_at: "2013-06-04 18:35:31", updated_at: "2013-06-04 18:35:31">]

我试过@category_questions[iteration_number][:some field]了，但没有用。

要获取哈希数组：

@category_questions.map do |question| 
  {question: question.question, status: question.question_status} 
end

要获取数组数组：

@category_questions.map {|question| [question.question, question.question_status] }
