猫鼬批量插入错误

Question

我在node.js上开玩笑，我正在使用mongoose批量插入方法，即model.collection.insert在MongoDB中插入数据。当这个方法执行时会给出如下错误：

但数据在数据库中成功插入。有人可以告诉我为什么我得到这个错误？

     index: [Getter], 
     errmsg: [Getter], 
     getOperation: [Function], 
     toJSON: [Function], 
     toString: [Function] } ] } 

这里是代码：

mOfferCake.collection.insert（jsonArr，{ continueOnError：真， keepGoing：真 }，onInsert）;

1） mOfferCake是模型和下面是代码：

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 
var offerCakeSchema = new Schema({ 
    offer_id: { 
     type: Number, 
     unique: true 
    } 
}); 

var datetime = new Date(); 
var mm = datetime.getMonth() + 1; 
if (mm < 10) { 
    mm = '0' + mm; 
} 
var dd = datetime.getDate(); 
if (dd < 10) { 
    dd = '0' + dd; 
} 
var yyyy = datetime.getFullYear(); 
var collectionName = 'MX_' + yyyy + '_' + mm + '_' + dd; 
module.exports = mongoose.model(collectionName, offerCakeSchema); 

2） jsonArr是JSON对象的阵列

3）onInsert是回调函数

function onInsert(err, docs) { 
if (err) { 
console.log(err); 
} 
else { 
    console.error("Cron bulk insert Successfully"); 
} 

}

code: 11000,

E11000手段重复键错误索引。

您可能使用_id插入文档已存在于集合中。
