Node.js用mongo创建函数

Question

我正在尝试创建一个事件并将其存储在我的mongo数据库中。以下是我当前的事件模式。

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 

//blueprint for each new entry in the db 
var eventSchema = new Schema({ 
    eventName: {type:String}, 
    eventDate: {type:String}, 
    eventPlace:{type:String}, 
    eventPrice: {type: Number} 

}); 
module.exports = mongoose.model('Event', eventSchema); 

这里是我的user.js的我创建的功能代码文件

// /route for new event 
    router.get('/newEvent', function (req,res,next) { 
     var messages = req.flash('error'); 
     res.render('user/newEvent',{csrfToken: req.csrfToken(),messages: messages, hasErrors: messages.length >0}); 
    }); 

    //route for new event save 
    router.get('/createEvent', function(req, res, next) { 

     var event = new Event(); 
     eventName = req.body.eventName; 
     eventDate = req.body.eventDate; 
     eventPlace = req.body.eventPlace; 
     eventPrice = req.body.eventPrice; 

     event.save(function(err) { 
     if(err) return next(err); 
     res.json({ message : 'Success!'}); 
     }); 
    }); 

这里是我的表单创建我newEvent.hbs文件中的新事件。

<div class = "row"> 
      <div class="col-md-4 col-md-offset-4"> 
        <h1> Create a new Event</h1> 
       {{#if hasErrors}} 
        <div class=alert alert-danger"> 
         {{# each messages}} 
          <p>{{this}}</p> 
         {{/each}} 
        </div> 
       {{/if}} 

       <form action="/user/newEvent" method="post"> 
        <div class="form-group"> 
        <label for="eventName">Event Name</label> 
        <input type="text" id="eventName" name="eventName"class="form-control"> 
       </div> 

       <div class="form-group"> 
        <label for="eventDate">Event Date</label> 
        <input type="text" id="eventDate" name="eventDate" class="form-control"> 
       </div> 

       <div> 
        <label for="eventPlace">Place of Event</label> 
        <input type="text" id="eventPlace" name="eventPlace" class="form-control"> 
       </div> 

       <div> 
        <label for="eventPrice">Price of Event: €</label> 
        <input type="text" id="eventPrice" name="eventPrice" class="form-control"> 
       </div> 

       <input type="hidden" name="_csrf" value="{{ csrfToken}}"> 
       <a href="createEvent" class="pull-right btn btn-success" role="button">Create Event</a> 
      </form> 
    </div> 

到目前为止，当我运行的代码，我得到一个错误，指出事件名称，eventPlace，EVENTDATE和eventPrice是必需的，还没有被输入，但是当我删除“要求：真正的”从事件模式的新事件被创建，但没有数据存储在数据库中。

Answer 1

1 - 你是不是保存事件正确eventName = req.body.eventName

目前正在保存空对象，这就是为什么当您删除需要保存的空数据。

2 - 你还使用req.body与GET请求，你应该使用router.post

检查下面

router.post('/createEvent', function(req, res, next) { 

    var event = new Event({ 
    eventName:req.body.eventName, 
    eventDate : req.body.eventDate, 
    eventPlace : req.body.eventPlace, 
    eventPrice : req.body.eventPrice 
    }); 

    event.save(function(err) { 
    if(err) return next(err); 
    res.json({ message : 'Success!'}); 
    }); 
});
