Pymongo to control the addition of digital fields in MongoDB

In this paper, we describe the method of Pymongo to realize the addition of digital fields in MongoDB. Share to everyone for your reference. The specific analysis is as follows:

This is very useful, for example, we need to give the article access statistics, you can set a number field: Hit, and then each time you click on the change field to increase by 1

Import pymongo# Imports Pymongo Module conn = Pymongo. Connection () #连接本地mongodb数据库db =conn.database #database为数据库名称collection = db.article#article is the collection name, Equivalent to the table name in MySQL collection.update ({' _id ': ObjectId (ID), ' $inc ': {' hit ': 1}}) # 1 increase for hit field

Hopefully this article will help you with Python programming.
