Question

我很难用猫鼬做一件简单的事，但是我被卡住了，我不知道为什么。

我遇到此错误Type '{ time: any; value: any; applianceId: any; }' has no properties in common with type 'DeepPartial<Document>'.

在这里您可以找到我的架构：

import * as mongoose from 'mongoose';
const applianceDataSchema = new mongoose.Schema({
    applianceId: {type: mongoose.Schema.Types.ObjectId, required: true},
    time: {type: Number, required: true},
    value: {type: Number, required: true},
});

const ApplianceDataModel = mongoose.model('relationalApplianceData', applianceDataSchema);

export { ApplianceDataModel }

我的插入代码：

const appliance = model.appliances.find(a => a.name == data.appliance); // I find the correct appliance here
const doc = {
            time: data.time,
            value: data.value,
            applianceId: appliance._id // I use the objectId here
        };
const applianceDataModel = new ApplianceDataModel(doc); // Error here

我不知道出了什么问题，我想使用objectId对象从数据中引用我的设备。你能帮我吗？

此错误的原因是必需的deviceId，并且因为需要等待model.appliances.find（.....）

，所以device._id是未定义的

// add async to the callback function for your endpoint
app.post('/your_url', async (req,res)=>{

   const appliance = await model.appliances.find(a => a.name == data.appliance);
   if(!appliance) res.status(400).send({error:'appliance not found'});

   console.log(appliance._id); // should console the _id
   const doc = {
        time: data.time,
        value: data.value,
        applianceId: appliance._id 
    };

   const applianceDataModel = new ApplianceDataModel(doc);
   await applianceDataModel.save();
   res.send({message:'Appliance has been saved'}
});

猫鼬类型没有与'DeepPartial <Document>'类型相同的属性
