目標：創(chuàng)建學院管理模塊（學院和學校關(guān)聯(lián)起來）
目標
一、后臺三步驟：
1隆判、打開projectName文件犬庇，在models目錄下創(chuàng)建academy.js文件，接著文件操作：
models目錄
academy.js↓
const mongoose = require('mongoose')
const Schema= mongoose.Schema
const feld={
name: String,
//人物標簽
major:String,
renshu: Number,
school : { type: Schema.Types.ObjectId, ref: 'School' }
}
//自動添加更新時間創(chuàng)建時間:
let schema = new Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})
module.exports= mongoose.model('Academy',schema)
2侨嘀、找到projectName下的routes目錄臭挽，創(chuàng)建academy.js文件：
const router = require('koa-router')()
let Model = require("../db/models/academy");
router.prefix('/academy')
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('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中掛載路由：
const academy = require('./routes/academy')
app.use(academy.routes(), academy.allowedMethods())
二、前臺三步驟：
打開vue-admin-template-master文件咬腕，在src/views目錄下創(chuàng)建一個academy模塊欢峰，并在academy目錄下創(chuàng)建vue文件：
academy模塊
1.editor.vue為編輯文件，用于創(chuàng)建學院記錄：
1
editor.vue↓
<template>
<div class="dashboard-container">
<el-form ref="form" :model="form" label-width="80px">
<el-form-item label="學院名稱">
<el-input v-model="form.name"></el-input>
</el-form-item>
<el-form-item label="專業(yè)">
<el-input v-model="form.major"></el-input>
</el-form-item>
<el-form-item label="人數(shù)">
<el-input v-model="form.renshu"></el-input>
</el-form-item>
<el-form-item label="所屬學校">
<el-select v-model="form.school" placeholder="請選擇">
<el-option
v-for="item in options"
:key="item._id"
:label="item.name"
:value="item._id">
</el-option>
</el-select>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="onSubmit">立即創(chuàng)建</el-button>
<el-button>取消</el-button>
</el-form-item>
</el-form>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'academy',
computed: {
...mapGetters([
'name'
])
},
data(){
return{
options: [
],
apiModel:'academy',
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]
}
})
}
this.$http.post('/api/school/find').then(res => {
if(res&&res.length>0){
this.options = res
console.log('res:', res)
}
})
}
}
</script>
<style lang="scss" scoped>
.dashboard {
&-container {
margin: 30px;
}
&-text {
font-size: 30px;
line-height: 46px;
}
}
</style>
2.index.vue為目錄文件涨共，用于顯示結(jié)果：
2
index.vue↓
<template>
<div class="dashboard-container">
<el-table
:data="users"
style="width: 100%"
:row-class-name="tableRowClassName">
<el-table-column
prop="_id"
label="學院_id"
width="180">
</el-table-column>
<el-table-column
prop="name"
label="學院名稱"
width="180">
</el-table-column>
<el-table-column
prop="major"
label="專業(yè)"
width="180">
</el-table-column>
<el-table-column
prop="renshu"
label="人數(shù)">
</el-table-column>
<el-table-column
prop="school"
label="學校名稱"
width="180">
<template slot-scope="scope" >
<span class="" v-if="scope.row.school">
<el-tag
:type="scope.row.school.name === '深信' ? 'primary' : 'success'"
disable-transitions>{{scope.row.school.name}}</el-tag>
</span>
</template>
</el-table-column>
<el-table-column label="操作">
<template slot-scope="scope">
<el-button
size="mini"
@click="handleEdit(scope.$index, scope.row)">編輯
</el-button>
<el-button
size="mini"
type="danger"
@click="handleDelete(scope.$index, scope.row)">刪除
</el-button>
</template>
</el-table-column>
</el-table>
</div>
</template>
<script>
import { mapGetters } from 'vuex'
export default {
name: 'academy',
computed: {
...mapGetters([
'name'
])
},
data() {
return {
apiModel:'academy',
users: {}
}
},
methods: {
onSubmit() {
console.log(123434)
},
handleEdit(index, item) {
this.$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>
3.在index.js中添加路由：
{
path: '/academy',
component: Layout,
meta: { title: '學院管理', icon: 'example' },
redirect: 'academy',
children: [{
path: 'academy',
name: 'academy',
component: () => import('@/views/academy'),
meta: { title: '學院管理', icon: 'academy' }
},
{
path: 'editor',
name: 'editor',
component: () => import('@/views/academy/editor'),
meta: { title: '添加學院', icon: 'academy' }
}]
},
