    "_id" : ObjectId("5bfe6df9777d13255bb2ad7c"),

    "month" : 10.0,
    "week_count" : 48.0,
    "year" : 2018.0,
    "data" : [ 
        {
            "_id" : ObjectId("5bfe6df9c1e35824dfcce39f"),
            "date" : 27.0,
            "user_ids" : [ 
                {
                    "checkin_time" : 1543400937337.0,
                    "by" : ObjectId("5bb2aa12460b5f2ef97388e6"),

                    "point" : 1.0
                }, 
                {
                    "checkin_time" : 1543400937337.0,
                    "by" : ObjectId("5bb453b44817792ec972c1ab"),

                    "user_utc_checkin_time" : 1543401130940.0,
                    "user_time_zone" : "Asia/Kolkata",
                    "checkin_status" : 1.0,
                    "point" : 1.0
                }, 
                {
                    "checkin_time" : 1543400937337.0,
                    "by" : ObjectId("5bed113bcd1c075e045aa79e"),
                    "checkin_by" : ObjectId("5bed113bcd1c075e045aa79e"),
                    "user_utc_checkin_time" : 1543401594869.0,

                    "point" : 1.0
                }
            ]
        }
    ]

我正在使用

db.collectionName.findAndUpdate(
     {"data.user_ids.checkin_by":mongoose.Types.ObjectId(a) },  
     { $set :
        { "data.user_ids.$.checkin_status":2 }
     }
   )

Answer 1

尝试使用此：

db.collectionName.update(
{"data.user_ids.checkin_by":mongoose.Types.ObjectId(a) },
{"$set":{"data.user_ids.$.checkin_status":2 }}
)
