# CRUD
#### 技术：
### MongoDB+mongoose
##### 关键文件：
student.js
~~~javascript
let mongoose =require('mongoose')
let Schema =mongoose.Schema
mongoose.connect('mongodb://localhost/Student', {useNewUrlParser: true});
let commentSchema= new Schema({
name:{
type:String,
require:true
},
gender:{
type:Number,
enum:[0,1],
default:0
},
hobbies:{
type:String,
},
fruits:{
type:String,
}
})
module.exports=mongoose.model('Student',commentSchema)
~~~
router.js
~~~javascript
/*
* 路由模块
* */
let express = require('express')
let router = express.Router()
let student = require('./student')
router.get('/', function (req, res) {
student.find(function (err, students) {
if (err) {
return res.status(500).send('Serve Error')
}
res.render('index.html', {
students: students
})
})
})
