请教一个 mongoose 的问题

最近写了一个爬虫去采集数据，数据结构大概是

    { pid: 'LY-0002-06', name: '8', id: '195296' },
    { pid: 'LY-0002-06', name: '9', id: '195271' },
    { pid: 'LY-0002-06', name: '10', id: '195272' },

    { pid: 'LY-0002-06', name: '16', id: '195300' }
  ]
}

目前是使用 mongoose 的 findOneAndUpdate 方法去新增或更新数据，回调函数只能读取到修改前或修改后的整条记录的值。目前的需求是我希望能够知道每次变更数据时，具体修改了哪个字段该怎么办呢？
