MongoDB: 正确保存数据到模型

Question

目标：用户模型需要为用户关联工作数据。我需要能够像这样使用 EJS 访问用户的工作数据：<%= user.jobs[0] %>

当前用户模型：

var UserSchema = new mongoose.Schema({
    username: String,
    password: String,
    jobs :[{
    name: String,
    score: String
    }]
});

用户名和密码工作正常。但是我需要让工作数据正常工作。工作数据是一个前端 javascript 数组，包含 200 个特定于用户的排名工作。

我可以像这样访问这个变量中的数据：

$( "#testButton").click(function() {
fetch('/test', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify(jobs)
}).then((response) => {
console.log(response)
}).catch((err) => {
console.log(err);
})

这给我的数据看起来像这样...

[{ 
name: 'Administrative assistant',
score: -48 },
{ 
name: 'Adult literacy instructor',
score: 28 },
{ 
name: 'Advertising copywriter',
score: 45
}]

我的问题是......我如何获取这些数据......并将其正确地放入用户模型中？注意：我正在使用 body-parser.

我的 POST 路线示例...

router.post("/register", function(req, res){
  var newUser = new User({username: req.body.username});
  User.register(newUser, req.body.password, function(err, user){
      if(err){
      .... etc.

models/User.js

const mongoose = require("mongoose");

const schema = new mongoose.Schema({
  username: String,
  password: String,
  jobs: [
    {
      name: String,
      score: String,
    },
  ],
});

module.exports = mongoose.model("user", schema);

index.js

const app = require("express")();
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
const User = require("./models/User");

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.post("/users", async (req, res) => {
  const user = await User.create({
    username: req.body.username,
    password: req.body.password,
    jobs: req.body.jobs,
  });
  return res.status(201).json({
    message: "Created",
    data: user,
  });
});

mongoose.connect("mongodb://root:toor@0.0.0.0:27017/Whosebug");
mongoose.connection.on("error", err => console.error(err));
app.listen(3000, () => console.log("Listening on :3000"));

使用 /users 的数据发出 post 请求：

{
    "username": "jon",
    "password": "snow",
    "jobs": [
        {
            "name": "software dev", "score": "10 pts"
        },
        {
            "name": "frontend dev", "score": "8 pts"

        }
    ]
}

将return:

{
    "message": "Created",
    "data": {
        "_id": "5d86ec91023b9785f2b455bb",
        "username": "jon",
        "password": "snow",
        "jobs": [
            {
                "_id": "5d86ec91023b9785f2b455bd",
                "name": "software dev",
                "score": "10 pts"
            },
            {
                "_id": "5d86ec91023b9785f2b455bc",
                "name": "frontend dev",
                "score": "8 pts"
            }
        ],
        "__v": 0
    }
}
