一、后台三步骤：
1、打开projectName文件，在models目录下创建teacher.js文件，接着文件操作：

const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
    name: String,
    age: String,
    //人物标签
    level:String,
    gender:String,
    school : { type: Schema.Types.ObjectId, ref: 'School' },
    academy : { type: Schema.Types.ObjectId, ref: 'Academy' }
}
//自动添加更新时间创建时间:
let personSchema = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Teacher',personSchema)

2、找到projectName下的routes目录，创建teacher.js文件：

const router = require('koa-router')()
let Model = require("../db/models/teacher");
router.prefix('/teacher')

router.get('/', function (ctx, next) {
    ctx.body = 'this is a users response!'
})

router.post('/add', async function (ctx, next) {
    console.log(ctx.request.body)
    let model = new Model(ctx.request.body);
    model = await model.save();
    console.log('user',model)
    ctx.body = model
})

router.post('/find', async function (ctx, next) {
    let models = await Model.
    find({}).populate('academy').populate('school')
    ctx.body = models
})

router.post('/get', async function (ctx, next) {
    // let users = await User.
    // find({})
    console.log(ctx.request.body)
    let model = await Model.find(ctx.request.body)
    console.log(model)
    ctx.body = model
})

router.post('/update', async function (ctx, next) {
    console.log(ctx.request.body)
    let pbj = await Model.update({ _id: ctx.request.body._id }, ctx.request.body);
    ctx.body = pbj
})
router.post('/delete', async function (ctx, next) {
    console.log(ctx.request.body)
    await Model.remove({ _id: ctx.request.body._id });
    ctx.body = 'shibai '
})
module.exports = router

3.在app.js中挂载路由：

const teacher= require('./routes/teacher')
app.use(teacher.routes(), teacher.allowedMethods())

二、前台三步骤：
打开vue-admin-template-master文件，在src/views目录下创建一个teacher模块，并在teacher目录下创建vue文件。

1.editor.vue为编辑文件，用于创建班级记录；

2.index.vue为目录文件，用于显示结果；

3.在index.js中添加路由：

  {
    path: '/teacher',
    component: Layout,
    meta: { title: '老师管理', icon: 'example' },
    redirect: '/teacher',
    children: [{
      path: 'teacher',
      name: 'teacher',
      component: () => import('@/views/teacher'),
      meta: { title: '老师管理', icon: 'user' }
    },
      {
        path: 'editor',
        name: 'editor',
        component: () => import('@/views/teacher/editor'),
        meta: { title: '添加老师', icon: 'user' }
      }]
  },
