node.js - Nodejs :Array data not added in mongodb

Question

这是我的模型profile.js

var mongoose = require('mongoose');

const ProfileSchema = mongoose.Schema({
    educationinfo: [{
        universityname:
        {
            type: String,
            required: true
        },
        degree:
        {
            type: String,
            required: true
        },
        coursecompletionyear:
        {
            type: String,
            required: true
        },
        collegename:
        {
            type: String,
            required: true
        },
        specialization:
        {
            type: String,
            required: true
        },
        marks:
        {
            type: String,
            required: true
        },
        courselevel:
        {
            type: String,
            required: true
        }
    }]
});

const Profile = module.exports = mongoose.model('Profile', ProfileSchema);

这是我的 route.js post 函数

router.post('/addprofiledetails', function(req, res, next) {
  let newProfile = new Profile({
    $educationinfo:[{
        universityname:req.body.universityname,
        degree:req.body.degree
    }]
  });
  newProfile.save((err, profile) => {
    if (err) {
        res.json({ msg: 'Failded to add profiledetails' });
    } else {
        res.json({ msg: 'successfully add profile details' });
    }
  });
});

我在 post 函数中收到成功消息，但数据未添加到 mongodb 中。我不知道我哪里做错了。请帮助我。

在 mongoDB 中我得到了这样的数据，

{
    "educationinfo": [],
    "_id": "5bed14b93a107411a0334530",
    "__v": 0
}

我想要educationinfo内的详细信息，请帮忙。

You need to change schema definition and query.

1.从架构中删除 required 或将 required 应用于您必须提供值的字段。

educationinfo: [{
        universityname:
        {
            type: String,
           // required: true
        },
        degree:
        {
            type: String,
            //required: true
        },
        coursecompletionyear:
        {
            type: String,
           // required: true
        },
        collegename:
        {
            type: String,
           // required: true
        },
        specialization:
        {
            type: String,
            //required: true
        },
        marks:
        {
            type: String,
           // required: true
        },
        courselevel:
        {
            type: String,
           // required: true
        }
    }]

2.将 $educationinfo 更改为 educationinfo

educationinfo:[{
    universityname:req.body.universityname,
    degree:req.body.degree
    }]
