Mongodb 用于更新嵌套数组的位置运算符

大家好，我有以下文件

{
    "_id" : ObjectId("568d5db6809af7688306901a"),
    "name" : "name",
    "market" : "market",
    "state" : "state",
    "products" : [ 
        {
            "updated" : ISODate("2016-11-11T23:07:11.114Z"),
            "quantity" : 9,
            "product" : "Prouct1",
            "_id" : ObjectId("58264bd882547072b855547f")
        }, 
        {
            "updated" : ISODate("2016-11-11T23:02:26.174Z"),
            "quantity" : 10,
            "product" : "Prouct2",
            "_id" : ObjectId("58264bd882547072b855546c")
        }, 
        {
            "updated" : ISODate("2016-11-11T23:02:26.174Z"),
            "quantity" : 10,
            "product" : "Prouct3",
            "_id" : ObjectId("58264bd882547072b855548a")
        }, 
        {
            "updated" : ISODate("2016-11-11T23:02:26.174Z"),
            "quantity" : 10,
            "product" : "Prouct4",
            "_id" : ObjectId("58264bd882547072b855576a")
        }, 
        {
            "updated" : ISODate("2016-11-11T22:58:14.083Z"),
            "quantity" : 10,
            "product" : "Prouct5",
            "_id" : ObjectId("58264bd882547072b855547f")
        }, 
        {
            "updated" : ISODate("2016-11-11T23:07:11.109Z"),
            "quantity" : -1,
            "product" : "Prouct5",
            "_id" : ObjectId("58264f1fa534b62abc89edf8")
        }, 
        {
            "updated" : ISODate("2016-11-11T23:07:11.119Z"),
            "quantity" : -1,
            "product" : "Prouct7",
            "_id" : ObjectId("58264f1fa534b62abc89edfa")
        }
    ]
}

下面是我的问题

query = {'products.product': {$in: ['Prouct1', 'Prouct2', 'Prouct3']}};

但以下更新仅更新Prouct1。如何将更新更改为更新Prouct1、Prouct2和Prouct3

update = {$inc: {'products.$.quantity': -1},'products.$.updated': now};

---

一如既往地感谢您的帮助和建议。

使用简单的查找查询无法完成这些操作。 变通办法

{$inc: {'products.0.quantity': -1,'products.1.quantity': -1,'products.2.quantity': -1}}

或 您可以使用聚合框架来

$unwind

阵列，

$match

文档网，更新文档网，然后再次

$push

将其放入阵列
