学校管理篇
一、从后端(projectName)添加学校模块
1、在models目录下添加school.js:
projectName/db/models/school.js:
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、在routes目录下添加school.js:
projectName/routes/school.js:
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',asyncfunction(ctx,next){console.log(ctx.request.body)letmodel=newModel(ctx.request.body);model=awaitmodel.save();console.log('user',model)ctx.body=model})
router.post('/find',asyncfunction(ctx,next){letmodels=awaitModel.find({})ctx.body=models})
router.post('/get',asyncfunction(ctx,next){// let users = await User.// find({})console.log(ctx.request.body)letmodel=awaitModel.find(ctx.request.body)console.log(model)ctx.body=model})
router.post('/update',asyncfunction(ctx,next){console.log(ctx.request.body)letpbj=awaitModel.update({_id:ctx.request.body._id},ctx.request.body);ctx.body=pbj})
router.post('/delete',asyncfunction(ctx,next){console.log(ctx.request.body)awaitModel.remove({_id:ctx.request.body._id});ctx.body='shibai '})
module.exports=router
3、在app.js中加上school模块的路由:
添加部分为:
school模块的路由
projectName/app.js:
constKoa=require('koa')
constapp=newKoa()
constviews=require('koa-views')
constjson=require('koa-json')constonerror=require('koa-onerror')
constbodyparser=require('koa-bodyparser')
constlogger=require('koa-logger')
constmongoose=require('mongoose')
constdbconfig=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 连接成功')});
// 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=newDate()
await next()
const ms=newDate()-start
console.log(`${ctx.method} ${ctx.url} - ${ms}ms`)
})
constindex=require('./routes/index')
app.use(index.routes(),index.allowedMethods())
constusers=require('./routes/users')
app.use(users.routes(),users.allowedMethods())
constschool=require('./routes/school')
app.use(school.routes(),school.allowedMethods())
// error-handling
// routes
app.on('error',(err,ctx)=>{
console.error('server error',err,ctx)
});
module.exports=app
二、从前端(vue-admin-template)添加学校模块
1、在src/views目录下添加school目录(模块),如图所示:
前端布局的school模块
①在school目录下添加editor.vue:
vue-admin-template/src/views/school/editor.vue:
立即创建
取消
import { mapGetters } from 'vuex' export default { name: 'school', computed: { ...mapGetters([ 'name' ]) }, data(){ return{ apiModel:'school', form:{} } }, methods:{ onSubmit(){ console.log('222:', 222) if(this.form._id){ this.$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.$route.query._id}).then(res => { if(res&&res.length>0){ this.form = res[0] } }) } } }
.dashboard { &-container { margin: 30px; } &-text { font-size: 30px; line-height: 46px; } }
效果图:
editor.vue的效果图
②在school目录下添加index.vue:
vue-admin-template/src/views/school/index.vue:
size="mini"@click="handleEdit(scope.$index, scope.row)">编辑
删除
.dashboard { &-container { margin: 30px; } &-text { font-size: 30px; line-height: 46px; } }
效果图:
index.vue的效果图
2、在router下的index.js中添加school模块的路由:
添加部分:
school模块的路由
vue-admin-template/src/router/index.js:
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
/* Layout */
importLayoutfrom'@/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 (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:'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'}}]},
{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=()=>newRouter({
// mode: 'history', // require service
supportscrollBehavior:()=>({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 defaul trouter
这样学校管理模块就构建好了,最终的效果图:
