Pymongo implements a method to control the addition of number fields in mongodb

This article illustrates pymongo's method to control the addition of number fields in mongodb. Share with you for your reference. Specific analysis is as follows:

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

import pymongo
# The import pymongo  The module 
conn = pymongo.Connection()
# Connected to the local mongodb The database 
db=conn.database #database Is the database name 
collection = db.article
#article for collection Name, equivalent to mysql In the name of the table 
collection.update({'_id':ObjectId(id),'$inc':{'hit':1}})
#  for hit Field increase 1

I hope this article has helped you with your Python programming.
