目标:创建班级管理模块(学生和班级、学院、学校关联起来)
一、后台三步骤:
1、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)
2、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
3.在app.js中挂载路由:
const classs= require('./routes/student')
app.use(student.routes(), student.allowedMethods())
二、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;
立即创建
取消
2.index.vue为目录文件,用于显示结果;
{{scope.row.school.name}}
{{scope.row.academy.name}}
{{scope.row.classs.name}}
编辑
删除
3.在index.js中添加路由:
{
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' }
}]
},
