How to use Python to implement the user logging function of a CMS system

With the development of the Internet, content management systems (CMS) are widely used in various websites such as enterprises, blogs, and news websites. For a CMS system, user login, registration, operation records and other information are very important, so it is very necessary to implement a reliable user logging function. This article will introduce how to use Python language to implement the user logging function of CMS system.

1. Design database table

First, we need to design a database table to store user logs. Suppose we have a table named "logs" with the following fields:

• id: the unique identifier of the log, an auto-incrementing integer type.
• user_id: The user’s unique identifier, integer type.
• operation: Description of user operation, string type.
• timestamp: The timestamp of the operation, date and time type.

You can use MySQL, SQLite and other relational databases to create this table. The following is a sample code using a SQLite database:

import sqlite3

def create_logs_table():
    conn = sqlite3.connect('database.db')
    cursor = conn.cursor()
    cursor.execute('''CREATE TABLE IF NOT EXISTS logs
                      (id INTEGER PRIMARY KEY AUTOINCREMENT,
                       user_id INTEGER,
                       operation TEXT,
                       timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP)''')
    conn.commit()
    conn.close()

2. Record user operations

In a CMS system, whenever a user performs an operation, we need to record the operation log. Logging code can be added to the corresponding function. The following is a sample function for saving the operation log of articles published by users:

def publish_article(user_id, article_title):
    # 执行发布文章操作的代码
    
    # 记录用户日志
    conn = sqlite3.connect('database.db')
    cursor = conn.cursor()
    operation = f"用户{user_id}发布了文章{article_title}"
    cursor.execute("INSERT INTO logs (user_id, operation) VALUES (?, ?)", (user_id, operation))
    conn.commit()
    conn.close()

By calling the above function, the operation information of articles published by users will be saved to the database.

3. Query user logs

Querying user log records is one of the commonly used functions for user rights management and system operation monitoring. The following is an example function for querying a user's log records:

def get_user_logs(user_id):
    conn = sqlite3.connect('database.db')
    cursor = conn.cursor()
    cursor.execute("SELECT * FROM logs WHERE user_id = ?", (user_id,))
    logs = cursor.fetchall()
    conn.close()
    return logs

By calling the above function and passing in the user's unique identifier, all operation logs of the user will be returned.

Summary:

This article introduces how to use Python language to implement the user logging function of the CMS system. By designing database tables to store user logs and adding log recording code at key operations, we can easily implement the recording and query functions of user operation logs. This is of great significance for user rights management, system operation monitoring, and subsequent data analysis and business optimization. If necessary, you can expand and optimize based on actual conditions.
