Javascript Mongoose.findOneAndUpdate（）未创建新文档

当客户端提供新的WEEKNUM时，mongoose.findOneAndUpdate（）方法不会创建新对象。相反，它只是更新集合中已经存在的WEEKNUM和WEEKDATA。我怎样才能解决这个问题？我错过了什么

模式：

{
    ageGroup:String,
    monthData: [{
    month:String,
    circleTimeWordsList:[String],
    circleTimeTips:[String],

    weekData : [{
        weekNum : String,
        theme   : String,

        dayData: [{
            day:String,
            circleTimeSong: String,
            circleTimeBook: String,
            circleTimeActivity: String,

            learningCenter: [{
                learningCenterName:String,
                learningCenterActivity:String 
            }]
        }]
    }]
}]
}

这是我的模式。我正在使用mongoose.findOneAndUpdate（）插入/更新集合中的数据

{
    ageGroup:"2",
    monthData: {
    month:"January",
    circleTimeWordsList:["word 1", "word 2"],
    circleTimeTips:["teaching tips", "teaching tips 2"],

    weekData : {
        weekNum : "1",
        theme   : "circleTime theme weekly 1",

        dayData: [{
            day:"Monday",
            circleTimeSong: "circleTimeSong 1", 
            circleTimeBook: "english 1", 
            circleTimeActivity: "circleTimeActivity 1", 

            learningCenter: [{
                learningCenterName:"Art Center",
                learningCenterActivity:"learningCenterActivity 1" 
            },
            {
                learningCenterName:"Language Center",
                learningCenterActivity:"learningCenterActivity 1"
            }]
        }]
    }
}

例如

如果我们没有收藏。将插入数据

如果集合中已经有以下数据

{
    ageGroup:"2",
    monthData: {
    month:"January",
    circleTimeWordsList:["word 1", "word 2"],
    circleTimeTips:["teaching tips", "teaching tips 2"],

    weekData : {
        weekNum : "1",
        theme   : "circleTime theme weekly 1",

        dayData: [{
            day:"Monday",
            circleTimeSong: "circleTimeSong 1", 
            circleTimeBook: "english 1", 
            circleTimeActivity: "circleTimeActivity 1", 

            learningCenter: [{
                learningCenterName:"Art Center",
                learningCenterActivity:"learningCenterActivity 1" 
            },
            {
                learningCenterName:"Language Center",
                learningCenterActivity:"learningCenterActivity 1"
            }]
        }]
    }
}

}

如果客户端向服务器发送以下JSON

{
        ageGroup:"2",
        monthData: {
        month:"January",
        circleTimeWordsList:["word 1", "word 2"],
        circleTimeTips:["teaching tips", "teaching tips 2"],

        weekData : {
            weekNum : "2",
            theme   : "circleTime theme weekly 2",

            dayData: [{
                day:"Monday",
                circleTimeSong: "circleTimeSong 2", 
                circleTimeBook: "english 2", 
                circleTimeActivity: "circleTimeActivity 2", 

                learningCenter: [{
                    learningCenterName:"Art Center",
                    learningCenterActivity:"learningCenterActivity 2" 
                },
                {
                    learningCenterName:"Language Center",
                    learningCenterActivity:"learningCenterActivity 2"
                }]
            }]
        }
    }
}

mongodb集合将如下所示：

{
        ageGroup:"2",
        monthData: {
        month:"January",
        circleTimeWordsList:["word 1", "word 2"],
        circleTimeTips:["teaching tips", "teaching tips 2"],

        weekData : [
                {
                    weekNum : "1",
                    theme   : "circleTime theme weekly 1",

                    dayData: [{
                        day:"Monday",
                        circleTimeSong: "circleTimeSong 1", 
                        circleTimeBook: "english 1", 
                        circleTimeActivity: "circleTimeActivity 1", 

                        learningCenter: [{
                            learningCenterName:"Art Center",
                            learningCenterActivity:"learningCenterActivity 1" 
                        },
                        {
                            learningCenterName:"Language Center",
                            learningCenterActivity:"learningCenterActivity 1"
                    }]
                },

                {
                    weekNum : "2",
                    theme   : "circleTime theme weekly 2",

                    dayData: [{
                        day:"Monday",
                        circleTimeSong: "circleTimeSong 2", 
                        circleTimeBook: "english 2", 
                        circleTimeActivity: "circleTimeActivity 2", 

                        learningCenter: [{
                            learningCenterName:"Art Center",
                            learningCenterActivity:"learningCenterActivity 2" 
                        },
                        {
                            learningCenterName:"Language Center",
                            learningCenterActivity:"learningCenterActivity 2"
                        }]
                    }]
                }
            ]
        }
    }
}

但是，当前代码只是更新旧数据，而不是在WEEKDATA数组中为weekNUM 2创建单独的对象

这是我正在使用的代码：

MyData.getMyDataModelObject().findOneAndUpdate({ageGroup:data.ageGroup, month:data.monthData.month/*, weekNum:data.monthData.weekData.weekNum*/}, data, {upsert:true}, function(err, foundData){});

---

假设请求是在体内发出的

var data=req.body;
delete data.weekData;
findOneAndUpdate(query,data,function(err,model){
  if(err){
// handle here
    }
 model.monthData.weekData.push(req.body.weekData);
 model.save();
});

在这种情况下，在mongoose中使用子文档必须在UR模式中进行更改，但如果UR执行CRUD操作，则是更好的选择
