Question

我将表单数据保存到NodeJS API，然后获取ID并将该ID保存到另一个文档。此时的表单实际上是将数据保存到我的MLab数据库，然后发送SERVER 500错误，并且没有进入console.logs进行故障排除。不知道发生了什么，因为该过程非常简单。

const express = require('express');
const router = express.Router();
const mongoose = require('mongoose');

const Project = require('../../models/project.model');
const Client = require('../../models/client.model');


router.post('/', async (req, res, next) => {

尝试一下，它应该可以正常工作。我们使用mongoose.Type。在定义模式时或在数据库中保存其实例时的ObjectId。您只需要存储其他模型实例ID作为参考，以后就可以使用它来检索foregin对象更换 _id：新的mongoose.Types.ObjectId（）通过型号名称：req。身体。 ID

const express = require('express');
const router = express.Router();
const mongoose = require('mongoose');

const Project = require('../../models/project.model');
const Client = require('../../models/client.model');


router.post('/', async (req, res, next) => {

    let newProject = new Project({

尝试保存并获取文档ID以将引用保存到另一个文档
