const feld={

    name: String,

    //人物标签

    major:String,

    renshu: Number,

    school : { type: Schema.Types.ObjectId, ref: 'School' }

}

//自动添加更新时间创建时间:

let schema = new Schema(feld, {timestamps: {createdAt: 'created', updatedAt: 'updated'}})

module.exports= mongoose.model('Academy',schema)

```

找到projectName下的routes目录,创建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

```

})

module.exports = router

```

3.在app.js中挂载路由:

```

const classs= require('./routes/classs')

app.use(classs.routes(), classs.allowedMethods())

```

前台三步骤:

打开vue-admin-template-master文件,在src/views目录下创建一个classs模块,并在academy目录下创建vue文件。

```

```

3.在index.js中添加路由:

```

{

    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' }

      }]

  },

```

实训五

打开projectName文件,在models目录下创建student.js文件,接着文件操作:

```

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)

```

找到projectName下的routes目录,创建student.js文件:

```

const router = require('koa-router')()

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

```

在app.js中挂载路由:

```

const classs= require('./routes/student')

app.use(student.routes(), student.allowedMethods())

```

前台三步骤:

打开vue-admin-template-master文件,在src/views目录下创建一个student模块,并在student目录下创建vue文件。

1.editor.vue为编辑文件,用于创建班级记录;

module.exports= mongoose.model('Teacher',personSchema)

```

找到projectName下的routes目录,创建teacher.js文件:

```

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
