Question

我正在尝试使用mongoose使用MEAN堆栈创建一个简单的注册表单。这是我的 models / dbSchema.js

＆＃13;

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var User = new mongoose.Schema({
   FirstName: String,
   LastName:  String,
   City    :  String,
   Email   :  String,
   Userid  :  String,
   Password:  String
    
});
module.export = mongoose.model('user', User);

＆＃13;

这是我的 server.js

＆＃13;

var express = require('express');
var app =  express();
var bodyParser = require('body-parser');
var jwt = require('jsonwebtoken');



app.use(express.static(__dirname + "/public"));


// configure app to use bodyParser()
// this will let us get the data from a POST
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/Regis_module');
var Userschema = require('./models/dbSchema'); 

 app.post('/regi',function(req,res){
     var schema        =  new Userschema();
     schema.Firstname      =  req.body.Fname;
     schema.Lastname      =  req.body.Lname;
     schema.City       =  req.body.city;
     schema.Email      =  req.body.email;
     schema.Userid     =  req.body.userid;
     schema.Password   =  req.body.password;
     
  schema.save(function(err) {
            if (err)
                res.send(err);

            res.json({ message: 'Record Inserted', Firstname: req.body.firstname, Lastname: req.body.lastname, city:req.body.city, email:req.body.email, 
                       userid:req.body.userid, password :req.body.password /*, fbId : req.body.fbId*/ });
        });
        
    });
    
app.listen(3000);
console.log("listening to port 3000");

在localhost上，在表单提交时，Firstname和Lastname不存储在数据库中。城市，电子邮件，用户ID和密码都存储正确。

如何正确存储数据库中的所有内容请帮帮我？

在以下代码行中，您使用req.body.Fname和req.body.Lname：

schema.Firstname = req.body.Fname;
schema.Lastname = req.body.Lname;

在下一行中，您使用req.body.firstname和req.body.lastname：

 res.json({ message: 'Record Inserted', Firstname: req.body.firstname, Lastname: req.body.lastname, city:req.body.city, email:req.body.email, 
                   userid:req.body.userid, password :req.body.password /*, fbId : req.body.fbId*/ });
    });

如果您的req.body对象与您的User架构具有相同的密钥，则可以使用mongoose的Model.create方法并将其传递给req.body。

对于您的代码，您将执行以下操作：

将用户模型带入您的server.js文件（let User = require('./models/dbSchema.js')）

然后您的app.post将如下所示：

app.post('/regi', function(req,res) {
 //pass the .create method the data from the body
  User.create(req.body, (err, savedUser) => {
    if(err) return res.send(err);
    res.send(savedUser);
  });
});

Mongoose模式不存储数据库中的所有内容
