在app.js中掛載路由：

二与倡、前臺三步驟：
打開vue-admin-template-master文件界逛，在src/views目錄下創(chuàng)建一個school模塊：
并在school目錄下創(chuàng)建vue文件。
<template>

console.log('222:', 222)
if(this.form._id){
this.$http.post(`/api/${this.apiModel}/update`,this.form).then(res => {
console.log('bar:', res)
this.$router.push({path:this.apiModel})
this.form={}

}else
{
this.$http.post('/api/'+this.apiModel+'/add',this.form).then(res => {

<style lang="scss" scoped>
.dashboard {

line-height: 46px;
}
}
</style>

3.在index.js中添加路由：
{

component: Layout,
meta: { title: '學校管理', icon: 'example' },
redirect: 'school',

},
項目三
打開projectName文件纺座，在models目錄下創(chuàng)建academy.js文件息拜，接著文件操作：
const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
name: String,

major:String,
renshu: Number,
school : { type: Schema.Types.ObjectId, ref: 'School' }
}
//自動添加更新時間創(chuàng)建時間:
let schema = new Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Academy',schema)
找到projectName下的routes目錄，創(chuàng)建academy.js文件：
const router = require('koa-router')()
let Model = require("../db/models/academy");
router.prefix('/academy')
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('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
.在app.js中掛載路由：
const academy = require('./routes/academy')
app.use(academy.routes(), academy.allowedMethods())
前臺三步驟：
打開vue-admin-template-master文件比驻，在src/views目錄下創(chuàng)建一個academy模塊：
image.png
并在academy目錄下創(chuàng)建vue文件该溯。
1.editor.vue為編輯文件，用于創(chuàng)建學院記錄别惦；

項目四
打開projectName文件掸掸，在models目錄下創(chuàng)建classs.js文件氯庆，接著文件操作：
const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
name: String,
//人物標簽
level:String,
renshu: Number,
school : { type: Schema.Types.ObjectId, ref: 'School' },
academy : { type: Schema.Types.ObjectId, ref: 'Academy' }
}
//自動添加更新時間創(chuàng)建時間:
let personSchema = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Classs',personSchema)
2蹭秋、找到projectName下的routes目錄，創(chuàng)建classs.js文件：
const router = require('koa-router')()
let Model = require("../db/models/classs");
router.prefix('/classs')
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中掛載路由：
const classs= require('./routes/classs')
app.use(classs.routes(), classs.allowedMethods())
前臺三步驟：
打開vue-admin-template-master文件堤撵，在src/views目錄下創(chuàng)建一個classs模塊仁讨，并在academy目錄下創(chuàng)建vue文件。
