How to use Python to implement the page management function of CMS system

With the continuous development and popularization of network technology, websites have become an important platform for enterprises and individuals to showcase themselves. Building a fully functional website requires a powerful and flexible CMS (Content Management System). In the CMS system, the page management function is an indispensable part. This article will introduce how to use Python language to implement the page management function of CMS system and provide code examples.

Design database table structure

Before implementing the page management function of the CMS system, we need to design the database table structure first. Taking MySQL as an example, you can create two tables: a table that stores page information and a table that stores page content.

-- 页面信息表
CREATE TABLE page (
    id INT PRIMARY KEY AUTO_INCREMENT,
    title VARCHAR(255) NOT NULL,
    url VARCHAR(255) NOT NULL UNIQUE,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

-- 页面内容表
CREATE TABLE page_content (
    id INT PRIMARY KEY AUTO_INCREMENT,
    page_id INT NOT NULL,
    content TEXT NOT NULL,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    FOREIGN KEY (page_id) REFERENCES page(id) ON DELETE CASCADE
);

Implementing the page management function

First, we need to use Python’s database operation library to connect to the database. Here we use the third-party library mysql-connector-python.

import mysql.connector

# 连接数据库
db = mysql.connector.connect(
    host="localhost",
    user="your_user",
    password="your_password",
    database="your_database"
)
cursor = db.cursor()

Next, we can implement some basic page management functions, such as adding pages, editing pages, deleting pages and getting page lists.

# 添加页面
def add_page(title, url):
    cursor.execute("INSERT INTO page (title, url) VALUES (%s, %s)", (title, url))
    db.commit()
    return cursor.lastrowid

# 编辑页面
def edit_page(page_id, title, url):
    cursor.execute("UPDATE page SET title=%s, url=%s WHERE id=%s", (title, url, page_id))
    db.commit()

# 删除页面
def delete_page(page_id):
    cursor.execute("DELETE FROM page WHERE id=%s", (page_id,))
    db.commit()

# 获取页面列表
def get_page_list():
    cursor.execute("SELECT id, title, url FROM page")
    return cursor.fetchall()

Page content management

In addition to page management functions, the CMS system also needs to provide page content management functions. We can add content, edit content, delete content and get content details for each page.

# 添加页面内容
def add_page_content(page_id, content):
    cursor.execute("INSERT INTO page_content (page_id, content) VALUES (%s, %s)", (page_id, content))
    db.commit()
    return cursor.lastrowid

# 编辑页面内容
def edit_page_content(content_id, content):
    cursor.execute("UPDATE page_content SET content=%s WHERE id=%s", (content, content_id))
    db.commit()

# 删除页面内容
def delete_page_content(content_id):
    cursor.execute("DELETE FROM page_content WHERE id=%s", (content_id,))
    db.commit()

# 获取页面内容详情
def get_page_content(content_id):
    cursor.execute("SELECT content FROM page_content WHERE id=%s", (content_id,))
    return cursor.fetchone()

Sample Code

Now we can write a sample code to demonstrate how to use these features.

# 添加页面
page_id = add_page("Homepage", "/home")

# 添加页面内容
content_id = add_page_content(page_id, "Welcome to our homepage!")

# 获取页面列表
page_list = get_page_list()
for page in page_list:
    print(f"Page ID: {page[0]}, Title: {page[1]}, URL: {page[2]}")

# 编辑页面
edit_page(page_id, "New Homepage", "/new-home")

# 编辑页面内容
edit_page_content(content_id, "Welcome to our new homepage!")

# 获取页面内容详情
content = get_page_content(content_id)
print(f"Content: {content[0]}")

# 删除页面内容
delete_page_content(content_id)

# 删除页面
delete_page(page_id)

# 关闭数据库连接
db.close()

The above are the steps and sample codes for implementing the page management function of the CMS system using Python language. Through these codes, we can implement functions such as adding, editing, deleting, and obtaining page lists, as well as adding, editing, deleting, and obtaining page content details. In this way, we can build a fully functional CMS system and realize the page management function entirely in Python language.
