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)
```
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) {

module.exports = router
```
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。
```
<template>
<div class="dashboard-container">
<el-form ref="form" :model="form" label-width="80px">
<el-form-item label="学校名称">
<el-input v-model="form.name"></el-input>
</el-form-item>
<el-form-item label="位置">
<el-input v-model="form.where"></el-input>
</el-form-item>
<el-form-item label="类型">
<el-input v-model="form.leixing"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary">立即创建</el-button>
<el-button>取消</el-button>
</el-form-item>
</el-form>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'school',
computed: {
...mapGetters([
'name'
])
},
data(){
return{
apiModel:'school',
form:{}
}
},
methods:{
onSubmit(){
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 => {
console.log('bar:', res)
this.$router.push({path:this.apiModel})
this.form={}
})
}
}
},
mounted() {
if(this.$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]
}
})
}
}
}
</script>
<style lang="scss" scoped>
.dashboard {
&-container {
margin: 30px;
}
&-text {
font-size: 30px;
line-height: 46px;
}
}
</style>
```
效果
```
<template>
<div class="dashboard-container">
<el-table :data="users" style="width: 100%" :row-class-name="tableRowClassName">
<!-- <el-table-column-->
<!-- prop="_id"-->
<!-- label="学校_id"-->

</el-table-column>
<el-table-column prop="where" label="位置" width="180">
</el-table-column>
<el-table-column prop="leixing" label="类型">
</el-table-column>
<el-table-column label="操作">
<template slot-scope="scope">
<el-button size="mini" scope.row>编辑
</el-button>
<el-button size="mini" type="danger" scope.row>删除
</el-button>
</template>
</el-table-column>
</el-table>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'school',
computed: {
...mapGetters([
'name'
])
},
data() {
return {
apiModel:'school',
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()
}
}
</script>
<style lang="scss" scoped>
.dashboard {
&-container {
margin: 30px;
}
&-text {
font-size: 30px;
line-height: 46px;
}
}
</style>
```
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' }
}]
},
```
项目三
打开projectName文件，在models目录下创建academy.js文件，接着文件操作：
```
const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
name: String,
//人物标签
major:String,
renshu: Number,
school : { type: Schema.Types.ObjectId, ref: 'School' }
}
//自动添加更新时间创建时间:
let schema = new Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Academy',schema)
```
找到projectName下的routes目录，创建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中挂载路由：
```
const academy = require('./routes/academy')
app.use(academy.routes(), academy.allowedMethods())
```
前台三步骤：
打开vue-admin-template-master文件，在src/views目录下创建一个academy模块：
并在academy目录下创建vue文件。
1.editor.vue为编辑文件，用于创建学院记录；
```
<template>

},
```
项目四
打开projectName文件，在models目录下创建classs.js文件，接着文件操作：
```
const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
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、找到projectName下的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 = 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 classs= require('./routes/classs')
app.use(classs.routes(), classs.allowedMethods())
```
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academy目录下创建vue文件。
