Javascript MongoError:不允许使用修饰符复制字段名

注：据我所知，我不是在做“推送”的事情

我有这个方法，第一次可以很好地工作，但是如果客户端在调用之间调用这个方法两次而没有刷新页面，我会在标题中得到错误

scenarios.findOne({'_id':partialUpdate._id},function(err,back){

            if(back){
                for(var p in partialUpdate){
                    if(partialUpdate.hasOwnProperty(p)){
                        back[p] = partialUpdate[p];
                    }
                }
                back.save(function(err,product,numberAffected){...

刷新页面可以阻止此错误发生的原因是什么？ 我怎样才能知道我复制的是哪个字段名，这样我就可以停止这个错误

这里是服务器输出的副本，其中包含第一组和第二组发送的数据（

partialData

），它与之合并的服务器数据（

back

），以及保存的数据（

product

），以及错误消息

我注意到的一个不同之处是，我没有向它发送objectid数组，而是向它发送字符串数组，而不是像2014年4月16日星期三12:02:49 GMT-0600（山地夏时制）这样的日期。我正在向它发送

2014-04-16T18:02:49.454Z

。这有关系吗？

修复了它：

我明确地保存了

\uv

属性，这是一个禁忌

---

在我的循环中，我只是检查

p

是否等于

\uu v

，如果是，我将忽略它。没有问题。

从github链接：将其添加到您的架构中：

\uv:{type:Number，select:false}
