編輯1設置TTL /到期日:使用貓鼬/ Node.js的對象
其實在進一步調查後似乎MogoDB只拿着最近的7條記錄,這是與我發送的方式做要叮叮噹噹的東西是否覆蓋了它們?
我刪除了TTL /超時的所有參考,我只看到最近的7個對象(有7個不同的對象要存儲,但隨着時間的推移有多個值)。
幫助非常感謝!

這似乎在文檔很簡單,但我不能讓它的工作。
我創建了一個模板,它看起來像這樣:
var trackingSchema = new mongoose.Schema({
VehicleID: {type: String, min: 0},
Label: {type: String, min: 0},
RegNumber: {type: String, min: 0},
VehPosDateTimeUTC: {type: String, min: 0},
Latitude: {type: String, min: 0},
Longitude: {type: String, min: 0},
Heading: {type: String, min: 0},
SpeedKPH: {type: String, min: 0},
OdometerKM: {type: String, min: 0},
SpeedMPH: {type: String, min: 0},
OdometerMiles: {type: String, min: 0},
EventCode: {type: String, min: 0},
GpsStrength: {type: String, min: 0},
Owner: {type: String, min: 0},
DriverName: {type: String, min: 0},
DriverID: {type: String, min: 0},
EventCodeId: {type: String, min: 0},
EventType: {type: String, min: 0},
createdAt: { type: Date, default : Date.now, expires: '1d'},
});
然而當通過貓鼬創建的對象,進入Mongolab設置的記錄只保留最多1分鐘。
我曾嘗試createdAt也行的其他變體,如:
createdAt: { type: Date, default : Date.now, expires: 6000 }
現在,我認爲這可能是時區的關係,但我真的不知道如何解決?
這裏是我使用的提交對象貓鼬代碼:
// Creating one vehicle record.
var vehicleData = new trackingRecord ({
VehicleID: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].VehicleID[0],
Label: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Label[0],
RegNumber: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].RegNumber[0],
VehPosDateTimeUTC:responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].VehPosDateTimeUTC[0],
Latitude: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Latitude[0],
Longitude: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Longitude[0],
Heading: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Heading[0],
SpeedKPH: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].SpeedKPH[0],
OdometerKM: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].OdometerKM[0],
SpeedMPH: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].SpeedMPH[0],
OdometerMiles: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].OdometerMiles[0],
EventCode: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].EventCode[0],
GpsStrength: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].GpsStrength[0],
Owner: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Owner[0],
DriverName: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].DriverName[0],
DriverID: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].DriverID[0],
EventCodeId: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].EventCodeId[0],
EventType: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].EventType[0]
});
// Saving it to the database.
vehicleData.save(function (err) {if (err) console.log ('Error on save!')});
它表現得像一個[封頂集合](http://docs.mongodb.org/manual/core/capped-collections/)。它是一個嗎? – JohnnyHK
