在mongodb python中查找并更新数组内的一个对象[重复]

Question

我正在尝试 db.collection.find() 我想找到带有 docId:'sparksLog' 的文档，然后在其中找到 'alerts' 然后 object2 具有图像中突出显示的时间戳 (1602579600000)，然后将最后一个字段值（有效：真）更新为（有效：假）

我用的是pymongo，python3.8

{
    "docId": "sparksLog",
    "alerts": [{
        "symbol": "ATOMUSDT",
        "candleDate": {
            "$date": "2020-10-13T03:30:00.000Z"
        },
        "spotDate": {
            "$date": "2020-10-14T22:36:56.795Z"
        },
        "timeStamp": 1602559800000,
        "alertPrice": 5.925,
        "side": "buy",
        "indicatorName": "Q1200",
        "currentPrice": 5.925,
        "changePercent": 0,
        "accuracy": 59,
        "forecast": 7.94,
        "rating": 5.9,
        "valid": true
    }, {
        "symbol": "ATOMUSDT",
        "candleDate": {
            "$date": "2020-10-13T09:00:00.000Z"
        },
        "spotDate": {
            "$date": "2020-10-14T22:36:57.416Z"
        },
        "timeStamp": 1602579600000,
        "alertPrice": 6.055,
        "side": "sell",
        "indicatorName": "Q140",
        "currentPrice": 6.055,
        "changePercent": 0,
        "accuracy": 59,
        "forecast": -3.25,
        "rating": 5.9,
        "valid": true
    }]
}

Answer 1

collection.update_one({
  "docId":'sparksLog'},
  {"$set": { 'alerts.$[t].valid':False}},
  array_filters=[{"t.timeStamp": 1602579600000}])
