如何更新数组中的子对象（更新）MongoDB

Question

我只想更新 where "sku": "abcd" 这 “收到”：34，到 “收到”：50，

我尝试使用 updateOne(

) 但不幸的是我得到了错误

{
  "_id": {
    "$oid": "62684e70e89eca781cc4f384"
  },
  "user": "ronen",
  "roles": {
    "User": 2001,
    "Editor": 1984,
    "Admin": 5150
  },
  
  "Stock": [
    {
      "sku": "777",
      "productname": "rone4n",
      "sendout": 5,
      "recived": 3,
      "totalinstock": 55,
      "location": "A770770",
      "_id": {
        "$oid": "626a9bb384cd350c6e784794"
      }
    },
    {
      "sku": "abcd",
      "productname": "ron",
      "sendout": 43,
      "recived": 34,
      "totalinstock": 444,
      "location": "fff",
      "_id": {
        "$oid": "626adab728fcc6005453a481"
      }
    }
  ],
 
}

我更喜欢MongoDB这边

我希望得到这样的东西

"sku": "abcd",
      "productname": "ron",
      "sendout": 43,
      "recived": 50,
      "totalinstock": 444,
      "location": "fff",
      "_id": {
        "$oid": "626adab728fcc6005453a481"

Answer 1

您可以使用 .update() 方法和 $set 来更新值。

db.collection.update({
  "stock.sku": "abcd"
},
{
  "$set": {
    "stock.$.recived": 50
  }
})

你可以查看mongo playground here

我在最后找到了答案在线阅读后感谢帮助过的人我附上代码也许它会对其他人有所帮助

await User.updateOne(
    {
        Stock: {
            $elemMatch: {
                sku: req.body.sku
            }
        }
    }, {
        $set: {
            "Stock.$.recived": addrecived
        }
    }
)
