一、后臺(tái)三步驟：
1、打開projectName文件册招，在models目錄下創(chuàng)建school.js文件抖单，接著文件操作：
const mongoose = require('mongoose')
const feld={
name: String,
//人物標(biāo)簽
where:String,
leixing: String
}
//自動(dòng)添加更新時(shí)間創(chuàng)建時(shí)間:
let personSchema = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('School',personSchema)
2拒秘、找到projectName下的routes目錄：
const router = require('koa-router')()
//建立模塊号显，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!'
})
//數(shù)據(jù)庫增刪改查
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中加上school模塊的路由：
projectName/app.js：
const Koa = require('koa')
const app = new Koa()
const views = require('koa-views')
const json = require('koa-json')
const onerror = require('koa-onerror')
const bodyparser = require('koa-bodyparser')
const logger = require('koa-logger')
const mongoose = require('mongoose')
const dbconfig = require('./db/config')
mongoose.connect(dbconfig.dbs,{useNewUrlParser: true,useUnifiedTopology: true})
const db = mongoose.connection
db.on('error',console.error.bind(console,'connection error:'));
db.once('open',function () {
console.log('mongoose 連接成功')
});
// error handler
onerror(app)
// middlewares
app.use(bodyparser({
enableTypes:['json', 'form', 'text']
}))
app.use(json())
app.use(logger())
app.use(require('koa-static')(__dirname + '/public'))
app.use(views(__dirname + '/views', {
extension: 'pug'
}))
// logger
app.use(async (ctx, next) => {
const start = new Date()
await next()
const ms = new Date() - start
console.log(`${ctx.method} ${ctx.url} - ${ms}ms`)
})
const index = require('./routes/index')
app.use(index.routes(), index.allowedMethods())
const users = require('./routes/users')
app.use(users.routes(), users.allowedMethods())
const school = require('./routes/school')
app.use(school.routes(),school.allowedMethods())
// error-handling
// routes
app.on('error', (err, ctx) => {
console.error('server error', err, ctx)
});
module.exports = app
二躺酒、從前端（vue-admin-template）添加學(xué)校模塊
1押蚤、在src/views目錄下添加school目錄（模塊），如圖所示：
image.png
①在school目錄下添加editor.vue：
vue-admin-template/src/views/school/editor.vue：
<template>
<div class="dashboard-container">
<el-form ref="form" :model="form" label-width="80px">
<el-form-item label="學(xué)校名稱">
<el-input v-model="form.name"></el-input>
</el-form-item>
<el-form-item label="位置">
<el-input v-model="form.where"></el-input>
</el-form-item>
<el-form-item label="類型">
<el-input v-model="form.leixing"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="onSubmit">立即創(chuàng)建</el-button>
<el-button>取消</el-button>
</el-form-item>
</el-form>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'school',
computed: {
...mapGetters([
'name'
])
},
data(){
return{
apiModel:'school',
form:{}
}
},
methods:{
onSubmit(){
console.log('222:', 222)
if(this.form._id){
this.$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.$route.query._id}).then(res => {
if(res&&res.length>0){
this.form = res[0]
}
})
}
}
}
</script>
<style lang="scss" scoped>
.dashboard {
&-container {
margin: 30px;
}
&-text {
font-size: 30px;
line-height: 46px;
}
}
</style>
②在school目錄下添加index.vue：
vue-admin-template/src/views/school/index.vue：
<template>
<div class="dashboard-container">
<el-table
:data="users"
style="width: 100%"
:row-class-name="tableRowClassName">
<!-- <el-table-column-->
<!-- prop="_id"-->
<!-- label="學(xué)校_id"-->
<!-- width="180">-->
<!-- </el-table-column>-->
<el-table-column
prop="name"
label="學(xué)校名稱"
width="180">
</el-table-column>
<el-table-column
prop="where"
label="位置"
width="180">
</el-table-column>
<el-table-column
prop="leixing"
label="類型">
</el-table-column>
<el-table-column label="操作">
<template slot-scope="scope">
<el-button
size="mini"
@click="handleEdit(scope.$index, scope.row)">編輯
</el-button>
<el-button
size="mini"
type="danger"
@click="handleDelete(scope.$index, scope.row)">刪除
</el-button>
</template>
</el-table-column>
</el-table>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'school',
computed: {
...mapGetters([
'name'
])
},
data() {
return {
apiModel:'school',
users: {}
}
},
methods: {
onSubmit() {
console.log(123434)
},
handleEdit(index, item) {
this.$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>
2羹应、在router下的index.js中添加school模塊的路由：
vue-admin-template/src/router/index.js：
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
/* Layout */
import Layout from '@/layout'
/**
* Note: sub-menu only appear when route children.length >= 1
* Detail see: https://panjiachen.github.io/vue-element-admin-site/guide/essentials/router-and-nav.html
*
* hidden: true if set true, item will not show in the sidebar(default is false)
* alwaysShow: true if set true, will always show the root menu
* if not set alwaysShow, when item has more than one children route,
* it will becomes nested mode, otherwise not show the root menu
* redirect: noRedirect if set noRedirect will no redirect in the breadcrumb
* name:'router-name' the name is used by <keep-alive> (must set!!!)
* meta : {
roles: ['admin','editor'] control the page roles (you can set multiple roles)
title: 'title' the name show in sidebar and breadcrumb (recommend set)
icon: 'svg-name' the icon show in the sidebar
breadcrumb: false if set false, the item will hidden in breadcrumb(default is true)
activeMenu: '/example/list' if set path, the sidebar will highlight the path you set
}
*/
/**
* constantRoutes
* a base page that does not have permission requirements
* all roles can be accessed
*/
export const constantRoutes = [
{
path: '/login',
component: () => import('@/views/login/index'),
hidden: true
},
{
path: '/school',
component: Layout,
meta: { title: '學(xué)校管理', icon: 'example' },
redirect: 'school',
children: [{
path: 'school',
name: 'school',
component: () => import('@/views/school'),
meta: { title: '學(xué)校管理', icon: 'school' }
},
{
path: 'editor',
name: 'editor',
component: () => import('@/views/school/editor'),
meta: { title: '添加學(xué)校', icon: 'school' }
}]
},
{
path: '/404',
component: () => import('@/views/404'),
hidden: true
},
{
path: '/',
component: Layout,
redirect: '/dashboard',
children: [{
path: 'dashboard',
name: 'Dashboard',
component: () => import('@/views/dashboard/index'),
meta: { title: 'Dashboard', icon: 'dashboard' }
}]
},
// 404 page must be placed at the end !!!
{ path: '*', redirect: '/404', hidden: true }
]
const createRouter = () => new Router({
// mode: 'history', // require service support
scrollBehavior: () => ({ y: 0 }),
routes: constantRoutes
})
const router = createRouter()
// Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465
export function resetRouter() {
const newRouter = createRouter()
router.matcher = newRouter.matcher // reset router
}
export default router
