网站前端开发-实训续篇+总结

实训五

学生管理篇（可将学校、学院、班级与学生关联起来）

一、从后端（projectName）添加学生模块

1、在models目录下添加student.js：

image.png

projectName/db/models/student.js：

const mongoose = require('mongoose')
const Schema = mongoose.Schema
const feld={
    name: String,
    age: Number,
    student_number:Number,
    gender:String,
    school : { type: Schema.Types.ObjectId, ref: 'School' },
    academy : { type: Schema.Types.ObjectId, ref: 'Academy' },
    classs : { type: Schema.Types.ObjectId, ref: 'Classs' }

}
//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('Student',personSchema)

2、在routes目录下添加student.js：

image.png
let Model = require("../db/models/student");
router.prefix('/student')

router.get('/', function (ctx, next) {
    ctx.body = 'this is a users response!'
})

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({}).populate('classs').populate('academy').populate('school')
    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student模块的路由：

添加部分为：

student模块的路由

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 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 = new Date()
  await next()
  const ms = new Date() - start
  console.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())
const student = require('./routes/student')
app.use(student.routes(), student.allowedMethods())
// error-handling




app.on('error', (err, ctx) => {
  console.error('server error', err, ctx)
});

module.exports = app

二、从前端（vue-admin-template）添加学生模块

1、在src/views目录下添加student目录（模块），如图所示：

前端布局的student模块
①在student目录下添加editor.vue：
vue-admin-template/src/views/student/editor.vue：
<template>
  <div class="dashboard-container">
    <el-form ref="form" :model="form" label-width="80px">
      <el-form-item label="所属学校">
        <el-select v-model="form.school" placeholder="请选择" @change="schoolChange">
          <el-option
            v-for="item in schools"
            :key="item._id"
            :label="item.name"
            :value="item._id">
          </el-option>
        </el-select>
      </el-form-item>
      <!--      编辑框：学院选择列表-->
      <el-form-item label="所属学院">
        <el-select v-model="form.academy" placeholder="请选择">
          <el-option
            v-for="item in academys"
            :key="item._id"
            :label="item.name"
            :value="item._id">
          </el-option>
        </el-select>
      </el-form-item>

      <el-form-item label="所属班级">
        <el-select v-model="form.classs" placeholder="请选择">
          <el-option
            v-for="item in classs"
            :key="item._id"
            :label="item.name"
            :value="item._id">
          </el-option>
        </el-select>
      </el-form-item>
      <el-form-item label="用户名">
        <el-input v-model="form.name"></el-input>
      </el-form-item>
      <el-form-item label="年龄">
        <el-input v-model="form.age"></el-input>
      </el-form-item>
      <el-form-item label="学号">
        <el-input v-model="form.student_number"></el-input>
      </el-form-item>
      <el-form-item label="性别">
        <el-input v-model="form.gender"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button type="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: 'student',
    computed: {
      ...mapGetters([
        'name'
      ])
    },
    data(){
      return{
        schools:[],
        academys:[],
        classs:[],
        options: [
        ],
        apiModel:'student',
        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.$http.post('/api/school/find').then(res => {
        if(res&&res.length>0){
          this.schools = res
          console.log('res:', res)
        }
      })
      //显示班级栏目
      this.$http.post('/api/classs/find').then(res => {
        if(res&&res.length>0){
          this.classs = res
          console.log('res:', res)
        }
      })
    }
  }
</script>

<style lang="scss" scoped>
  .dashboard {
    &-container {
      margin: 30px;
    }
    &-text {
      font-size: 30px;

student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 */
import Layout from '@/layout'

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: [{

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

这样学生管理模块就构建好了，最终的效果图：

学生管理模块

实训六

教师管理篇（可将学校、学院、班级、学生与教师关联起来）

一、从后端（projectName）添加教师模块

1、在models目录下添加teacher.js：

image.png

projectName/db/models/teacher.js：

const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
    name: String,
    age: String,
    //人物标签
    level:String,
    gender:String,
    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 = new mongoose.Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Teacher',personSchema)

2、在routes目录下添加teacher.js：

image.png

projectName/routes/teacher.js：

const router = require('koa-router')()
let Model = require("../db/models/teacher");
router.prefix('/teacher')

router.get('/', function (ctx, next) {
    ctx.body = 'this is a users response!'
})

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({}).populate('academy').populate('school')
    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teacher模块的路由：

添加部分为：

teacher模块的路由

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 连接成功')

二、从前端（vue-admin-template）添加教师模块

1、在src/views目录下添加teacher目录（模块），如图所示：

前端布局的teacher模块
①在teacher目录下添加editor.vue：
vue-admin-template/src/views/teacher/editor.vue：
<template>
  <div class="dashboard-container">
    <el-form ref="form" :model="form" label-width="80px">
      <el-form-item label="所属学校">
        <el-select v-model="form.school" placeholder="请选择" @change="schoolChange">
          <el-option
            v-for="item in schools"
            :key="item._id"
            :label="item.name"
            :value="item._id">
          </el-option>
        </el-select>
      </el-form-item>
      <!--      编辑框：学院选择列表-->
      <el-form-item label="所属学院">
        <el-select v-model="form.academy" placeholder="请选择">
          <el-option
            v-for="item in academys"
            :key="item._id"
            :label="item.name"
            :value="item._id">
          </el-option>
        </el-select>
      </el-form-item>
      <el-form-item label="用户名">
        <el-input v-model="form.name"></el-input>
      </el-form-item>
      <el-form-item label="年龄">
        <el-input v-model="form.age"></el-input>
      </el-form-item>
      <el-form-item label="性别">
        <el-input v-model="form.gender"></el-input>
      </el-form-item>
      <el-form-item label="级别">
        <el-input v-model="form.level"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button type="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: 'teacher-editor',
    computed: {
      ...mapGetters([
        'name'
      ])
    },
    data(){
      return{
        schools:[],
        academys:[],
        options: [
        ],
        apiModel:'teacher',
        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)
        }
      })
    }
  }
</script>

<style lang="scss" scoped>
  .dashboard {
    &-container {
      margin: 30px;
    }
    &-text {
      font-size: 30px;
      line-height: 46px;
    }
  }
</style>

效果图：

editor.vue的效果图
②在teacher目录下添加index.vue：
vue-admin-template/src/views/teacher/index.vue：
<template>
  <div class="dashboard-container">
    <el-table
      :data="users"
      style="width: 100%"

</style>

效果图：

index.vue的效果图

2、在router下的index.js中添加teacher模块的路由：

添加部分：

teacher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 */
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

    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: '/404',
    component: () => import('@/views/404'),
    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: '/student',
    component: Layout,
    meta: { title: '学生管理', icon: 'example' },
    redirect: '/student',
    children: [{
      path: 'student',
      name: 'student',
      component: () => import('@/views/student/index'),
      meta: { title: '学生管理', icon: 'user' }
    },
      {
        path: 'editor',
        name: 'editor',
        component: () => import('@/views/student/editor'),
        meta: { title: '添加学生', icon: 'user' }
      }]
  },
  {
    path: '/teacher',
    component: Layout,
    meta: { title: '老师管理', icon: 'example' },
    redirect: '/teacher',
    children: [{
      path: 'teacher',
      name: 'teacher',
      component: () => import('@/views/teacher'),
      meta: { title: '老师管理', icon: 'user' }
    },
      {
        path: 'editor',
        name: 'editor',
        component: () => import('@/views/teacher/editor'),
        meta: { title: '添加老师', icon: 'user' }
      }]
  },

  {
    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

这样教师管理模块就构建好了，最终的效果图：

教师管理模块
const school = require('./routes/school')
const academy = require('./routes/academy')
const classs= require('./routes/classs')
const student= require('./routes/student')
const teacher= require('./routes/teacher')

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 index = require('./routes/index')
const users = require('./routes/users')



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 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 = new Date()
  await next()
  const ms = new Date() - start
  console.log(`${ctx.method} ${ctx.url} - ${ms}ms`)
})

// routes

app.use(academy.routes(), academy.allowedMethods())
app.use(classs.routes(), classs.allowedMethods())
app.use(student.routes(), student.allowedMethods())
app.use(teacher.routes(), teacher.allowedMethods())
// error-handling
app.on('error', (err, ctx) => {
  console.error('server error', err, ctx)
});

module.exports = app

// error handler
onerror(app)

// middlewares
app.use(bodyparser({

app.use(json())
app.use(logger())

school-manager-admin

school-manager-admin这是一个极简的 vue admin 管理后台。它只包含了 Element UI & axios & iconfont & permission control & lint，这些搭建后台必要的东西。

目前版本为 v4.0+ 基于 vue-cli 进行构建，若你想使用旧版本，可以切换分支到tag/3.11.0，它不依赖 vue-cli。

Extra

如果你想要根据用户角色来动态生成侧边栏和 router，你可以使用该分支permission-control

相关项目

在这里我们使用了- electron-vue-admin
