Javascript 如何在嵌套数组中实现多字段更新

我在MongoDB中有嵌套数组，并试图更新第三级数组中的乘法值：

const query = {'_id': id};
const inc = {'$inc':
     {'threads.$[thread].shifts.$[shift].services.$[service].balance': balance}
};
const arrayFilters = {
     arrayFilters: [
          {'thread.number': threadNumber},
          {'shift.number':shiftNumber},
          {'service.name': service},
     ]
 };
 await Vds.findOneAndUpdate(query, inc, arrayFilters);

在本例中，我只更新了一个字段-仅

余额

，但我需要更新两个字段，

余额

和

上次更新

（这是时间余额更新）

我不得不写第二个查询：

const query = {'_id': id};
const inc = {'$inc':
     {'threads.$[thread].shifts.$[shift].services.$[service].lastUpdate': new Date()}
};
const arrayFilters = {
     arrayFilters: [
          {'thread.number': threadNumber},
          {'shift.number':shiftNumber},
          {'service.name': service},
     ]
 };
 await Vds.findOneAndUpdate(query, inc, arrayFilters);

如何合并此查询？比如：

const inc = {'$inc': [
     {'threads.$[thread].shifts.$[shift].services.$[service].balance': balance},
     {'threads.$[thread].shifts.$[shift].services.$[service].lastUpdate': new Date()},
 ]};

我在中见过，但没有找到类似的例子

模式：

new Schema({

    ... some data
    ,
    threads: [
        {
            number: {
                type: Number,
                required: true
            },

            shifts: [
                {

                    ... some data

                    number: {
                        type: Number,
                        required: true
                    },
                    services: [
                        {
                            name: {
                                type: String,
                                required: true
                            },
                            lastUpdate: {
                                type: Date,
                                default: null
                            },
                            balance: {
                                type: Number,
                                default: 0
                            }

                            ... some data

                        }
                    ]
                }
            ]

        }
    ]
});

这两个字段都应位于

$inc

运算符内

const query = { '_id': id }
const update = { '$inc': {
  'threads.$[thread].shifts.$[shift].services.$[service].balance': balance,
  'threads.$[thread].shifts.$[shift].services.$[service].lastUpdate': new Date()
}}
const arrayFilters = {
  arrayFilters: [
    { 'thread.number': threadNumber },
    { 'shift.number' :shiftNumber },
    { 'service.name': service },
  ]
}
await Vds.findOneAndUpdate(query, update, arrayFilters)

或者，如果要

$set

，请单击

lastUpdate

字段

const query = { '_id': id }
const update = {
  '$inc': { 'threads.$[thread].shifts.$[shift].services.$[service].balance': balance },
  '$set': { 'threads.$[thread].shifts.$[shift].services.$[service].lastUpdate': new Date() }
}
const arrayFilters = {
  arrayFilters: [
    { 'thread.number': threadNumber },
    { 'shift.number' :shiftNumber },
    { 'service.name': service },
  ]
}
await Vds.findOneAndUpdate(query, update, arrayFilters)

在第二种情况下，使用了

$set

我得到了

更新路径'threads.$[thread].shift.$[shift].services.$[service].balance'会在'threads.$[thread].shift.$[shift].services.$[service].balance'

处产生冲突。在第一个使用

$inc

的情况下，我得到的

无法使用非数字参数递增：{threads.$[thread].shift.$[shift].services.$[service].lastUpdate:new Date（1534699306238）}

可能是我的lastUpdate的默认值

null

？lastUpdate的数据类型是什么？类型

Date

我在问题中添加了模式。可能

Date

类，对于MongoDB中的日期容器不是一个好的选择？我刚刚检查了它是否适合我。。。你能把你收集的样品寄出去吗
