Question

我有一个列表，其中可以包含一些项目，这些项目可以具有子项目，而这些子项目可以具有其子项目，依此类推。.Iam能够插入新项目及其子项目并更新这些项目的列表更改，但是当尝试插入子项目的子项目时，我的列表没有更新。这是我插入子项的功能

   let addSubItems = (req, res) => {
if (check.isEmpty(req.params.itemId)) {
    console.log("error:item id not found")
    let apiResponse = response.generate(true, 'no itemId found', 403, null)
    res.send(apiResponse)
} else {
    ItemModel.findOne({ "itemId": req.params.itemId }).exec((err, result) => {
        if (err) {
            console.log(err)
            let apiResponse = response.generate(true, 'err occured in item find', 403, null)
            res.send(apiResponse)
        }else if(check.isEmpty(result)){
            console.log("no item matched")
            let apiResponse = response.generate(true, 'no item found', 403, null)
            res.send(apiResponse)
        } 
        else {

            console.log("this is the item inside which subitem is to be added")
            console.log(result)
            let newItem = new ItemModel({
                itemId: shortid.generate(),
                itemTitle: req.body.itemTitle,
                isDone: req.body.isDone

            })

            newItem.save((err, generatedItem) => {
                if (err) {
                    logger.error(`Error Occured : ${err}`, 'Database', 10)
                    console.log(err)
                    let apiResponse = response.generate(true, 'Error Occured.', 500, null)
                    res.send(apiResponse)
                } else {
                    console.log('Success in new item creation, new generated item is-')
                    console.log(generatedItem)
                    result.child.push(newItem)
                    let listId = req.body.listId
                    result.save()
                    console.log("result after saving")
                    console.log(result)
                    ListModel.findOneAndUpdate({ "listId": req.body.listId, "items.itemId": req.params.itemId},
                    { "$set": { "items.$": result } }, {new:true}).exec((err, updatedlistresult) => {
                        if (err) {
                            console.log('error in finding list for save')
                            console.log(err)
                        } else if(check.isEmpty(updatedlistresult)){
                            let apiResponse = response.generate(true, 'updated result is empty', 500, null)
                            res.send(apiResponse)
                        }
                        else {
                            let apiResponse = response.generate(false, 'item saved', 200, updatedlistresult)
                            res.send(apiResponse)
                        }
                    })

                }
            })
        }
    })
}

} 我的模式是-

  let listSchema = new Schema({
listId:{
    type:String,
    default:'',
    required: true,
    index:true
},
listTitle:{
    type:String
},
forUserId:{
    type:String,
    default: ''
},
items:[ItemSchema]

}） mongoose.model（'List'，listSchema）;

//项目架构

     itemSchema.add({
itemId:{
    type:String,
    default:'',
    index:true
},
itemTitle:{
    type:String
},
isDone:{
    type:Boolean,
    default:false
},
child:[itemSchema]

}）

插入子子文档时更新父文档
