Pymongo realizes the method of controlling the addition of digital field in MongoDB

This article mainly introduced the Pymongo realizes the control MongoDB the numerical field to do the addition the method, involves Python uses the Pymongo module operation MongoDB database field The skill, has certain reference value, the need friend may refer to under

The example of this paper describes the method of Pymongo to control the addition of digital fields in MongoDB. Share to everyone for your reference. The specific analysis is as follows:

This is very practical, for example, we need to give the article to do access statistics, you can set a number of fields: hit, and then each click to change the field to add 1 can

Import Pymongo #import pymongo
  Module conn = Pymongo. Connection () #Connect to the local mongodb database db = conn.database #database is the database name
  collection = Db.article #article is the collection name,
  Equivalent to the table name in MySQL collection.update (('_id': ObjectId (ID), '$ inc': ('hit': 1))) # add 1 to the hit field

I hope this article will help you with your Python programming.
