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', 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({})
    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school模块的路由：

添加部分为：

school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`)
})



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())
// 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：

<template>
  <div class="dashboard-container">
    <el-form ref="form" :model="form" label-width="80px">
      <el-form-item label="学校名称">
        <el-input v-model="form.name"></el-input>
      </el-form-item>
      <el-form-item label="位置">
        <el-input v-model="form.where"></el-input>
      </el-form-item>
      <el-form-item label="类型">
        <el-input v-model="form.leixing"></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: '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>

<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school目录下添加index.vue：

vue-admin-template/src/views/school/index.vue：

<template>
  <div class="dashboard-container">
    <el-table
      :data="users"
      style="width: 100%"
      :row-class-name="tableRowClassName">
      <!--      <el-table-column-->
      <!--        prop="_id"-->
      <!--        label="学校_id"-->
      <!--        width="180">-->
      <!--      </el-table-column>-->
      <el-table-column
        prop="name"
        label="学校名称"
        width="180">
      </el-table-column>
      <el-table-column
        prop="where"
        label="位置"
        width="180">
      </el-table-column>
      <el-table-column
        prop="leixing"
        label="类型">
      </el-table-column>
      <el-table-column label="操作">
        <template slot-scope="scope">
          <el-button
            size="mini"
            @click="handleEdit(scope.$index, scope.row)">编辑
          </el-button>
          <el-button
            size="mini"
            type="danger"
            @click="handleDelete(scope.$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>

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

    &-text {
      font-size: 30px;
      line-height: 46px;
    }
  }
</style>

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 */
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
 * name:'router-name'             the name is used by <keep-alive> (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 = () => 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

这样学校管理模块就构建好了，最终的效果图：
