您好我正在尝试使用Mongoose在Sails中编写一个逻辑，以使用串行编号以字符串格式查找和更新Mongoose数据库中的参数。我传递的参数位于DHC应用程序的正文中（用于将数据发布到API）。在发布数据时，我收到以下错误
TypeError: undefined is not a function

使用Node Inspector我发现我的FindOneAndUpdate代码失败，如下所示
var msg_parts=params.msg_parts;
/*msg_parts.SerialNo=params.SerialNo;*/ // Adding the Serial no into the message parts for storing in the mongo Database
var statuspacket=db.StatusPacket(msg_parts);
//For saving into the Database
statuspacket.findOneAndUpdate({"SerialNo":SerialNo1},msg_parts,function(err,data){
if (err) {
res.json({
success: false,
exception: err
});
return;
}else{
statuspacket.save(function(err,data){
if(err){
res.json({
success: false,
exception: err
});
return;
}else{
res.json({
success: true,
data:data
});
return;
}
});
}
});
数据库的MY Schema如下
var schema=new mongoose.Schema({
// Serial No of the device.We require an Index on this column
SerialNo:{
type: String,
required:true,
index:true
},
// battery level will take values from 0 to 6(0,1,2,3,4,5,6)
batteryLevel:{
type:Number,
min:0,
max:6
},
//Signal Level will take values from 0 to 4 (0,1,2,3,4)
signalLevel:{
type:Number,
min:0,
max:4,
},
//Charging status=false represents Charging OFF And true represents charging on
chargingStatus:{
type:Boolean,
default:false
},
// 7 states of the alarm
alarmInfo:{
type:Number
},
// false represents GPS OFF And true represents GPS on
gpsStatus:{
type:Boolean
},
//Default time when the new packet arrived
createdAt: {
type: Date,
default: Date.now
}
});
有人可以帮助我解决错误，因为我无法理解我在FindOneAndUpdate错误的位置吗？
