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:

    .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:

            

       

    

    .dashboard {    &-container {      margin: 30px;    }    &-text {      font-size: 30px;      line-height: 46px;    }  }

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:
