修改属性在MongoDB中的显示顺序 [英] Modify the order in which properties are displayed in MongoDB

问题描述

我正在使用PyMongo将数据(title, description, phone_number ...)插入到MongoDB中.但是，当我使用mongo客户端查看数据时，它以奇怪的顺序显示属性.具体来说，首先显示phone_number属性，然后显示title，然后显示description.有什么方法可以强制执行特定命令?

I am using PyMongo to insert data (title, description, phone_number ...) into MongoDB. However, when I use mongo client to view the data, it displays the properties in a strange order. Specifically, phone_number property is displayed first, followed by title and then comes description. Is there some way I can force a particular order?

推荐答案

原始答案(2013):

MongoDB文档是BSON对象，是键-值对的无序字典.因此，您不能依赖或设置特定的字段顺序.您唯一可以操作的是显示哪些字段而不显示哪些字段，请参见find的

MongoDB documents are BSON objects, unordered dictionaries of key-value pairs. So, you can't rely on or set a specific fields order. The only thing you can operate is which fields to display and which not to, see docs on find's projection argument.

也请参阅SO的相关问题:
