Pymongo realizes the method of controlling the addition of digital fields in MongoDB _python

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
#导入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, the equivalent of the table name
collection.update ({' _id ': ObjectId (ID), ' $inc ': {' hit ': 1}}})
# 1 for the hit field

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