Question

我是新的平均堆栈我完成了更新，删除和获取数据，但无法在mongoose中插入数据，任何人都可以帮助我。谢谢以下是我的代码。

var express = require('express');
var mongojs = require('mongojs');
var db = require('mongoose');
var bodyParser = require('body-parser');

var app = express();
app.use(express.static(__dirname + "/public"));
app.use(bodyParser.json());
db.connect('mongodb://localhost/contactlist');
var db1 = db.connection;
db1.on('error', err);
db1.once('open',startserver);
function err(){
console.log('connection error:');
}
function startserver(){
console.log('start');
app.listen(3000);
}
var contactdetails1 = new db.Schema({
    name:String,
    email:String,
    password:String,
    number:String  
});
db1.model('Contactdetails',contactdetails1);

app.post('/contactList',function(req,res){
  console.log("Get insert request"+req.body);
//var contactList = new ContactList(req.body);
  var contactdetails1 = new db.Schema({
   name:req.body.name,
    email:req.body.email,
    password:'',
    number:req.body.number        
    });


  contactdetails1.save(function(err,data) {
        if (err) {
            response = {
                "status":0,
                "error":err,
            };
        }else{
            response = {
                "status":1,
                "data":data,
                "message":"User registered successfully"
            };
        }
        console.log(response);
        res.json(response);   
    });       
});

当错误显示

时，此时插入数据

Test处的未定义类型name 你尝试过嵌套Schemas吗？您只能使用refs或数组进行嵌套。在Function.Schema.interpretAsType（/usr/lib/node_modules/mongoose/lib/schema.js:666:11）在Schema.path（/usr/lib/node_modules/mongoose/lib/schema.js:545:29）在Schema.add（/usr/lib/node_modules/mongoose/lib/schema.js:429:12）在新架构（/usr/lib/node_modules/mongoose/lib/schema.js:100:10） at /var/www/html/contactlistappmvc/server.js:53:25

Answer 1

var contactdetails1 = new db.Schema({
name:req.body.name,
email:req.body.email,
password:'',
number:req.body.number        
});

您应该保存模型，而不是模式。你在这里做的是将一个对象传递给模式。文档是模型的实例，而不是模式。模式只是一个对象定义。

而不是你在这里做了什么，为什么不做呢

var ContactModel = mongoose.model('Contactdetails',contactdetails1);


var contactModel = new ContactModel({
name:req.body.name,
email:req.body.email,
password:'',
number:req.body.number 
})

然后执行contactModel.save()

无法使用mongoose插入数据
