班级管理篇
(可将学校、学院与班级关联起来)
一、从后端(projectName)添加班级模块
1、在models目录下添加classs.js:
projectName/db/models/classs.js:
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'},
academy:{type:Schema.Types.ObjectId,ref:'Academy'}
}
//自动添加更新时间创建时间:
let personSchema=newmongoose.Schema(feld,{timestamps:{createdAt:'created',updatedAt:'updated'}})
module.exports=mongoose.model('Classs',personSchema)
2、在routes目录下添加classs.js:
projectName/routes/classs.js:
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',asyncfunction(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',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classs模块的路由:
添加部分为:
projectName/app.js:
const Koa=require('koa')
const app=newKoa()constviews=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})
constdb=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)=>{
conststart=newDate()awaitnext()constms=newDate()-startconsole.log(`${ctx.method} ${ctx.url} - ${ms}ms`)})
// routes
const index=require('./routes/index')
app.use(index.routes(),index.allowedMethods())
const users=require('./routes/users')
app.use(users.routes(),users.allowedMethods())
const school=require('./routes/school')
app.use(school.routes(),school.allowedMethods())
const academy=require('./routes/academy')
app.use(academy.routes(),academy.allowedMethods())
const classs=require('./routes/classs')
app.use(classs.routes(),classs.allowedMethods())
// error-handling
app.on('error',(err,ctx)=>{console.error('server error',err,ctx)});
module.exports=app
二、从前端(vue-admin-template)添加班级模块
1、在src/views目录下添加classs目录(模块),如图所示:
①在classs目录下添加editor.vue:
vue-admin-template/src/views/classs/editor.vue:
v-for="item in schools":key="item._id":label="item.name":value="item._id">
v-for="item in academys":key="item._id":label="item.name":value="item._id">
立即创建
取消
import { mapGetters } from 'vuex' export default { name: 'classs', computed: { ...mapGetters([ 'name' ]) }, data(){ return{ schools:[], academys:[], //列表内容 options: [ ], apiModel:'classs', form:{} } }, methods:{ onSubmit(){ if(this.form._id){ this.$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.$http.post('/api/school/find').then(res => { if(res&&res.length>0){ this.schools = res console.log('res:', res) } }) } }
.dashboard { &-container { margin: 30px; } &-text { font-size: 30px; line-height: 46px; } }
效果图:
②在classs目录下添加index.vue:
vue-admin-template/src/views/classs/index.vue:
{{scope.row.school.name}}
{{scope.row.academy.name}}
编辑
删除
import { mapGetters } from 'vuex' export default { name: 'classs', computed: { ...mapGetters([ 'name' ]) }, data() { return { apiModel:'classs', users: {} } }, methods: { onSubmit() { console.log(123434) }, handleEdit(index, item) { this.$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; } }
效果图:
2、在router下的index.js中添加classs模块的路由:
添加部分:
vue-admin-template/src/router/index.js:
importVuefrom'vue'importRouterfrom'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
*/exportconstconstantRoutes=[{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:'/academy',component:Layout,meta:{title:'学院管理',icon:'example'},redirect:'academy',children:[{path:'academy',name:'academy',component:()=>import('@/views/academy'),meta:{title:'学院管理',icon:'academy'}},{path:'editor',name:'editor',component:()=>import('@/views/academy/editor'),meta:{title:'添加学院',icon:'academy'}}]},{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'}}]},{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}]constcreateRouter=()=>newRouter({// mode: 'history', // require service supportscrollBehavior:()=>({y:0}),routes:constantRoutes})constrouter=createRouter()// Detail see: https://github.com/vuejs/vue-router/issues/1234#issuecomment-357941465exportfunctionresetRouter(){constnewRouter=createRouter()router.matcher=newRouter.matcher// reset router}exportdefaultrouter
这样班级管理模块就构建好了,最终的效果图:
