ejs模板數據沒有插入到mongodb

我想從ejs模板中使用貓鼬向mongodb插入數據。頁面在點擊提交按鈕後成功重定向，我的數據也在url中顯示，但沒有插入MongoDB Collection。ejs模板數據沒有插入到mongodb

app.js

var express = require('express'); 
    var path = require('path'); 
    var favicon = require('serve-favicon'); 
    var logger = require('morgan'); 
    var cookieParser = require('cookie-parser'); 
    var bodyParser = require('body-parser'); 
    var mongoose = require('mongoose'); 
    var mongodb = require('mongoDB'); 

    var routes = require('./routes/index'); 
    var users = require('./routes/users'); 

    var app = express(); 

    // view engine setup 
    app.set('views', path.join(__dirname, 'views')); 
    app.set('view engine', 'ejs'); 

    // database connection 
    mongoose.connect('mongodb://localhost/company'); 
    var mySchema=new mongoose.Schema({ 
    name:String, 
    email:String 
    }); 
    var user=mongoose.model('emp', mySchema); 


    // uncomment after placing your favicon in /public 
    //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); 
    app.use(logger('dev')); 
    app.use(bodyParser.json()); 
    app.use(bodyParser.urlencoded({ extended: false })); 
    app.use(cookieParser()); 
    app.use(express.static(path.join(__dirname, 'public'))); 

    app.use('/', routes); 
    app.use('/users', users); 

    // catch 404 and forward to error handler 
    app.use(function(req, res, next) { 
    var err = new Error('Not Found'); 
    err.status = 404; 
    next(err); 
    }); 

    // error handlers 

    // development error handler 
    // will print stacktrace 
    if (app.get('env') === 'development') { 
    app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
     message: err.message, 
     error: err 
    }); 
    }); 
    } 

    // production error handler 
    // no stacktraces leaked to user 
    app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
    message: err.message, 
    error: {} 
    }); 
    }); 


    module.exports = app;

Index.ejs

<!DOCTYPE html> 
    <html> 
    <head> 
    <title><%= title %></title> 
    <link rel='stylesheet' href='/stylesheets/style.css' />

    <body> 

    <div style="margin:0 auto ; width:50%; padding:20px">

index.js

var express = require('express'); 
    var router = express.Router(); 

    /* GET home page. */ 
    router.get('/', function(req, res, next) { 
    res.render('index', { title: 'Express' }); 
    }); 
    router.post('/users', function(req, res, next) { 
    new user({ 
    name:req.body.name, 
    email:req.body.email 

    }).save(function(err, docs){ 
    if(err) 
    { 
    res.json(err); 
    } 
    else 
    { 
    res.send('success Inserted !'); 
    } 
    }); 
    }); 

    module.exports = router;

見'新用戶（..）'。您不會導入您的用戶模型，也不會顯示其中定義的任何代碼。 –

首先你必須定義表單POST方法BEC您可以定義路線類型的信息。而在你的index.js文件中，你並沒有初始化用戶對象和數據連接，所以你必須在你在app.js文件中定義的index.js文件中初始化用戶和數據連接。從app.js文件中刪除用戶初始化和數據連接。

代碼：

index.ejs

<!DOCTYPE html> 
    <html> 
    <head> 
    <title><%= title %></title> 
    <link rel='stylesheet' href='/stylesheets/style.css' /> 
    </head> 
    <body> 

    <div style="margin:0 auto ; width:50%; padding:20px"> 
    <form action="/users" method="post"> 
    <label>Name</label> 
    <input type="text" name="name"> 
     <br /> <br /> <br /> <br /> 
    <label>Email</label> 
    <input type="text" name="email"> 
     <br /> <br /> <br /> <br /> 
    <button>submit</button> 
     </form> 
    </div> 
    </body> 
    </html>

index.js

var express = require('express'); 
    var router = express.Router(); 
    // database connection 
    mongoose.connect('mongodb://localhost/company'); 
    var mySchema=new mongoose.Schema({ 
    name:String, 
    email:String 
    }); 
    var user=mongoose.model('emp', mySchema); 
     /* GET home page. */ 
     router.get('/', function(req, res, next) { 
     res.render('index', { title: 'Express' }); 
     }); 
     router.post('/users', function(req, res, next) { 
     new user({ 
     name:req.body.name, 
     email:req.body.email 

     }).save(function(err, docs){ 
     if(err) 
     { 
     res.json(err); 
     } 
     else 
     { 
     res.send('success Inserted !'); 
     } 
     }); 
     }); 

     module.exports = router;
