嵌套 MongoDB 文档问题（Mongoose 和 Node Js）

Question

我在将数据插入 mongoDb 的嵌套文档结构时遇到一些问题。

以下是 Mongoose 模型：

const funnel = new mongoose.Schema({
funnelName:{
    type:String,
    unique:true
},
group: String,
category: String,
funnelStep: {
    stepType: String,
    stepName: String,
    stepPath: String,
    isTracking: Boolean,
    viewsStorage: []
} })

下面是我发送给 Db 的推送：

router.post('/createFunnel',async (req,res)=>{
if(!req.body.funnelName || !req.body.group || !req.body.category)
    {return res.status(422).json({error:"Please add all the fields."})}
try{
    const funnelSteps = []
    funnelSteps.push({
        stepType: req.body.stepType,
        stepName: req.body.stepName,
        stepPath: req.body.stepPath,
        isTracking: req.body.isTracking,
        viewsStorage: req.body.viewsStorage
    })
    const funnels = new Funnel({
        funnelName : req.body.funnelName,
        group : req.body.group,
        category : req.body.category,
        funnelStep : funnelSteps
    })
    await funnels.save(function(err){
        if(err){
            return res.status(422).send({error: err.message})
        }
        return res.json(funnels)
    })
} catch(err){
    return res.status(422).send({error: err.message})
} })

下面是我通过邮递员发送的数据结构：

{
"funnelName":"Name-Funnel",
"group":"AVC",
"category":"XYZ",
"funnelStep":[
    {
        "stepType":"Advert",
        "stepName":"Angle",
        "stepPath":"google.com",
        "isTracking":1,
        "viewsStorage":[0,0]
    },
    {
        "stepType":"Optin",
        "stepName":"Ver 1",
        "stepPath":"fb.com",
        "isTracking":1,
        "viewsStorage":[1,0]
    },
    {
        "stepType":"Check",
        "stepName":"rev-cat",
        "stepPath":"google.com",
        "isTracking":0,
        "viewsStorage":[2,0]
    }
] }

下面是我得到的响应输出：

{
    "funnelStep": {
        "viewsStorage": []
    },
    "_id": "5ec0ff78a6dfab18f4210e96",
    "funnelName": "Testing The Latest Method4",
    "group": "AVC",
    "category": "XYZ",
    "__v": 0
}

由于我的数据没有正确插入，我该如何解决这个问题？

除此之外，在viewsStorage数组中，如何存储日期和一个在一定操作后会增加并根据日期保存在数组中的数字？

我认为 funnelSteps 数组创建部分存在问题。您正在尝试直接从 req.body 而不是 req.body.funnelStep

获取数据

const funnelSteps = []
req.body.funnelStep.forEach(fs => {
    funnelSteps.push({
        stepType: fs.stepType,
        stepName: fs.stepName,
        stepPath: fs.stepPath,
        isTracking: fs.isTracking,
        viewsStorage: fs.viewsStorage
    })
})

架构

const funnel = new mongoose.Schema({
funnelName:{
    type:String,
    unique:true
},
group: String,
category: String,
funnelStep: [{
    stepType: String,
    stepName: String,
    stepPath: String,
    isTracking: Boolean,
    viewsStorage: []
}] })
