目标：创建班级管理模块（班级和学院、学校关联起来）一、后台三步骤：
1、在db->models目录下创建classs.js文件，接着文件操作：

const mongoose = require('mongoose')const Schema= mongoose.Schemaconstfeld={
name: String,
//人物标签
level:String,
renshu: Number,
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('Classs',personSchema)

2、在routes目录，创建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 = newModel(ctx.request.body);
model =awaitmodel.save();
console.log('user',model)
ctx.body = model
})

router.post('/find', async function(ctx, next){
let models = awaitModel.
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 = awaitModel.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 classs= require('./routes/classs')
app.use(classs.routes(), classs.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classs模块，并在classs目录下创建vue文件。
1.editor.vue为编辑文件，用于创建班级记录；

import { mapGetters } from 'vuex'

export default{
name: 'classs',
computed: {
...mapGetters([
'name'
])
},
data(){
return{
schools:[],
academys:[],
//列表内容
options: [
],
apiModel:'classs',
form:{}
}
},
methods:{
onSubmit(){
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 => {
console.log('bar:', res)
this.$router.push({path:this.apiModel})
this.form={}
})
}
},
schoolChange(val1){
//显示学院选择栏目
this.$http.post('/api/academy/get',{school:val1}).then(res => {
if(res&&res.length>0){
this.academys = res
console.log('res:', res)
}
})
}
},
mounted() {
if(this.$route.query._id){
this.$http.post('/api/'+this.apiModel+'/get',{_id:this.$route.query._id}).then(res => {
if(res&&res.length>0){
this.form = res[0]
this.schoolChange(this.form.school)
}
})
}

//显示学校选择栏目
this.$http.post('/api/school/find').then(res => {
if(res&&res.length>0){
this.schools = res
console.log('res:', res)
}
})
}
}

.dashboard {
&-container {
margin: 30px;
}
&-text {
font-size: 30px;
line-height: 46px;
}
}

2.index.vue为目录文件，用于显示结果；

import { mapGetters } from 'vuex'

export default{
name: 'classs',
computed: {
...mapGetters([
'name'
])
},
data() {
return{
apiModel:'classs',
users: {}
}
},
methods: {
onSubmit() {
console.log(123434)
},
handleEdit(index, item) {
this.$router.push({ path: '/'+this.apiModel+'/editor', query: {_id:item._id} })
},
handleDelete(index, item) {
this.$http.post('/api/'+this.apiModel+'/delete', item).then(res => {
console.log('res:', res)
this.findUser()
})

},
findUser(){
this.$http.post('/api/'+this.apiModel+'/find', this.user).then(res => {
console.log('res:', res)
this.users = res
})
}
},
mounted() {
this.findUser()
}
}

.dashboard {
&-container {
margin: 30px;
}

&-text {
font-size: 30px;
line-height: 46px;
}
}

3.在router->index.js中添加路由：

{
path: '/classs',
component: Layout,
meta: { title: '班级管理', icon: 'example'},
redirect: '/classs',
children: [{
path: 'classs',
name: 'classs',
component: () => import('@/views/classs'),
meta: { title: '班级管理', icon: 'classs'}
},
{
path: 'editor',
name: 'editor',
component: () => import('@/views/classs/editor'),
meta: { title: '添加班级', icon: 'classs'}
}]
