node.js - 更新 MongoDB 集合 - JavaScript

Question

我正在尝试更新集合中的值。用户单击一个按钮，与该按钮对应的数字将被发送到服务器以添加到集合中。

我无法更新集合，但如果我使用db.orders.update()，它在控制台中工作正常

订单型号:

// DB Initiation stuff

var orderSchema = new mongoose.Schema({ 
    status: String,
    rated: Number
});

var collection = 'orders';
var Order = db.model('Order', orderSchema, collection);

module.exports = Order;

客户端(点击按钮时)

// starID = 5; id = 50e6a57808a1d92dcd000001
socket.emit('rated', {rated: starID, id: id});

socket.js:

var Order = require('../models/orders');

socket.on('rated', function(data) { 
  /* Probably a better way to do this but, wrap
   * the id in 'ObjectId(id)'
   */
  var id = 'ObjectId("'+data.id+'")';
  Order.update( {_id: id}, {$set: {rated: data.rated}} );
   socket.emit('updated', {
     note: 'Some HTML notification to append'
   });  
});

让 Mongoose 将 id 字符串转换为 ObjectId:

socket.on('rated', function(data) { 
  Order.update( {_id: data.id}, {$set: {rated: data.rated}} );
   socket.emit('updated', {
     note: 'Some HTML notification to append'
   });  
});
