定义创建数据表
定义创建数据表
//创建一个Schema
const createSchema = mongoose.Schema({
name: {type: String, required: true },
age: {type: Number, required: true }
})
const User = mongoose.model('users', createSchema)
数据的简单查找
User.find({}, function(err, doc){
console.log(doc)
})
新建
User.create({
name : 'afacode',
age: 19 + Math.random()
}, function(err, doc){
if(err){
console.log(err)
}else{
console.log(doc)
}
})
先这样
