一、后台三步骤：

1、打开projectName文件，在models目录下创建school.js文件，接着文件操作：

const mongoose = require('mongoose')
const feld={
    name: String,
    //人物标签
    where:String,
    leixing: String
}
//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('School',personSchema)

2、找到projectName下的routes目录：

const router = require('koa-router')()
//建立模块，require(“../db/models/文件名”)
let Model = require("../db/models/school");
router.prefix('/school')

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

//数据库增删改查
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({})
    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 school = require('./routes/school')
app.use(school.routes(), school.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school模块：

并在school目录下创建vue文件。

1.editor.vue为编辑文件，用于创建学校记录；

2.index.vue为目录文件，用于显示结果；

3.在index.js中添加路由：

{
    path: '/school',
    component: Layout,
    meta: { title: '学校管理', icon: 'example' },
    redirect: 'school',
    children: [{
      path: 'school',
      name: 'school',
      component: () => import('@/views/school'),
      meta: { title: '学校管理', icon: 'school' }
    },
      {
        path: 'editor',
        name: 'editor',
        component: () => import('@/views/school/editor'),
        meta: { title: '添加学校', icon: 'school' }
      }]
  },
