学院管理部分
（即学校与学院联系起来）
后端（projectName）添加学院模块
在projectName/db/models/下新建academy.js
const mongoose = require('mongoose')
const Schema= mongoose.Schema
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)
在projectName/routes/下添加academy.js：
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
在app.js中加上academy模块的路由：
添加部分为：
academy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`)
})
// routes
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())
const academy = require('./routes/academy')
app.use(academy.routes(), academy.allowedMethods())
// error-handling
app.on('error', (err, ctx) => {
console.error('server error', err, ctx)
});
module.exports = app
从前端（vue-admin-template）添加学院模块
在src/views目录下添加academy目录（模块），如图所示：
前端布局的academy模块
在academy目录下添加editor.vue：
vue-admin-template/src/views/academy/editor.vue：
立即创建
取消
在academy目录下添加index.vue：
vue-admin-template/src/views/academy/index.vue：
{{scope.row.school.name}}
编辑
删除
在router下的index.js中添加academy模块的路由：
添加部分：
academy模块的路由
vue-admin-template/src/router/index.js：
import Vue from 'vue'
import Router from 'vue-router'
Vue.use(Router)
