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、在routes目录下添加school.js:

projectName/routes/school.js:

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中加上school模块的路由:

添加部分为:

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})constdb=mongoose.connectiondb.on('error',console.error.bind(console,'connection error:'));db.once('open',function(){console.log('mongoose 连接成功')});// error handleronerror(app)// middlewaresapp.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'}))// loggerapp.use(async(ctx,next)=>{conststart=newDate()awaitnext()constms=newDate()-startconsole.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// routesapp.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:

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;

                                                                              立即创建        取消           
  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]          }        })      }    }  }  .dashboard {    &-container {      margin: 30px;    }    &-text {      font-size: 30px;      line-height: 46px;    }  }

2.index.vue为目录文件,用于显示结果;

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

3.在src里面的router/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'}}]},
