如果有很多项验证怎么办？要写很多遍“不能为空” ？有没有简洁的写法？

activerecord:
  models:
    user: "用户"
  attributes:
    user:
      name: "姓名"
      tel: "电话"
      job: "期望职位"
  errors:
    models:
      user:
        attributes:
          name:
            blank: "不能为空"
          tel:
            blank: "不能为空"
          job:
            blank: "不能为空"
