【问题描述】：

我正在使用node.js 并使用mongoose 批量插入方法，即model.collection.insert 在MongoDB 中插入数据。当此方法执行时，会出现以下错误：

但是数据在数据库中插入成功。有人能告诉我为什么会出现这个错误吗？

       toJSON: [Function],
       toString: [Function]  ] 

代码如下：

mOfferCake.collection.insert(jsonArr, 继续错误：真， 继续前进：是的 , onInsert);

1) mOfferCake 是模型，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 对象数组

3) onInsert 是回调函数

function onInsert(err, docs) 
if (err) 
console.log(err);

else 
    console.error("Cron bulk insert Successfully");

节点版本：v4.5.0 猫鼬版本：4.6.5

【参考方案1】：

代码：11000，

E11000 表示重复键错误索引。

您可能插入了集合中已存在_id 的文档。

【讨论】：

每次我插入新数据集并自动生成_id
