一、后台三步骤：

1、打开projectName文件，在models目录下创建school.js文件，接着文件操作：

constmongoose=require('mongoose')constfeld={name:String,//人物标签where:String,leixing:String}//自动添加更新时间创建时间:letpersonSchema=newmongoose.Schema(feld,{timestamps:{createdAt:'created',updatedAt:'updated'}})module.exports=mongoose.model('School',personSchema)

2、找到projectName下的routes目录：

constrouter=require('koa-router')()//建立模块，require(“../db/models/文件名”)letModel=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中挂载路由：

constschool=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。

1.editor.vue为编辑文件，用于创建学校记录；

<template><divclass="dashboard-container"><el-formref="form":model="form"label-width="80px"><el-form-itemlabel="学校名称"><el-inputv-model="form.name"></el-input></el-form-item><el-form-itemlabel="位置"><el-inputv-model="form.where"></el-input></el-form-item><el-form-itemlabel="类型"><el-inputv-model="form.leixing"></el-input></el-form-item><el-form-item><el-buttontype="primary"@click="onSubmit">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><stylelang="scss"scoped>.dashboard { &-container { margin: 30px; } &-text { font-size: 30px; line-height: 46px; } }</style>

2.index.vue为目录文件，用于显示结果；

<template><divclass="dashboard-container"><el-table:data="users"style="width: 100%":row-class-name="tableRowClassName"><el-table-columnprop="name"label="学校名称"width="180"></el-table-column><el-table-columnprop="where"label="位置"width="180"></el-table-column><el-table-columnprop="leixing"label="类型"></el-table-column><el-table-columnlabel="操作"><templateslot-scope="scope"><el-buttonsize="mini"@click="handleEdit(scope.$index, scope.row)">编辑</el-button><el-buttonsize="mini"type="danger"@click="handleDelete(scope.$index, 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><stylelang="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'}}]
