How to use Python to develop the web page generator function of a CMS system
With the development of the Internet, content management systems (CMS) play an important role in website development. CMS systems can help developers easily create, edit and manage website content. In this article, we will explore how to use Python to develop the web page generator function of a simple CMS system.
- Design the data model
Before we start writing code, we must first design our data model. A typical CMS system usually contains entities such as Page, Article, and User. Here we take the page as an example to design a simple page model.
class Page:
def __init__(self, title, content):
self.title = title
self.content = contentThis simple page class contains two attributes: title and content.
- Create a web page generator class
Next, we create a web page generator class, which is responsible for generating the HTML code of the web page. We use Python's string formatting capabilities to insert the title and content of the page.
class PageGenerator:
def generate_page(self, page):
template = """
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>{}</title>
</head>
<body>
<h1>{}</h1>
<div>{}</div>
</body>
</html>
"""
html = template.format(page.title, page.title, page.content)
return html- Using the web page generator
Now, we can use the web page generator to generate web pages. First, we create a page object and pass it to the web page generator.
page = Page("Welcome to my website", "This is the content of the page.")
generator = PageGenerator()
html = generator.generate_page(page)
print(html)Run the above code and you will get an HTML code containing the page title and content. You can save the generated HTML code as an html file and then open it in the browser to see the generated web page.
- Connect to the database
Now, let’s extend our CMS system to read the page content from the database and save the generated web page to the database . We use SQLite as our database.
First, we need to install Python’s SQLite library.
pip install sqlite3
Next, we create a database connection class and add some basic operation methods.
import sqlite3
class Database:
def __init__(self, db_file):
self.db_file = db_file
def create_tables(self):
conn = sqlite3.connect(self.db_file)
c = conn.cursor()
c.execute("CREATE TABLE IF NOT EXISTS pages (id INTEGER PRIMARY KEY AUTOINCREMENT, title TEXT, content TEXT)")
conn.commit()
conn.close()
def insert_page(self, page):
conn = sqlite3.connect(self.db_file)
c = conn.cursor()
c.execute("INSERT INTO pages (title, content) VALUES (?, ?)", (page.title, page.content))
conn.commit()
conn.close()
def get_pages(self):
conn = sqlite3.connect(self.db_file)
c = conn.cursor()
c.execute("SELECT * FROM pages")
rows = c.fetchall()
conn.close()
return rows- Using database operations
Now, we can use database operations. We first create a database object and call the create_tables method to create tables.
db = Database("cms.db")
db.create_tables()Then, let’s insert some pages.
page1 = Page("About Us", "This is the about us page.")
page2 = Page("Contact", "You can contact us at contact@example.com.")
db.insert_page(page1)
db.insert_page(page2)Finally, we get all the pages and use the web page generator to generate HTML code.
pages = db.get_pages()
for page in pages:
html = generator.generate_page(Page(page[1], page[2]))
print(html)Run the above code and you will get the HTML code of all pages obtained from the database.
Summary
In this article, we introduced how to use Python to develop the web page generator function of the CMS system. We designed a simple page model and web page generator class, and used a SQLite database to store the pages. Through this simple example, you can extend this CMS system and add more functions, such as user management, article management, etc. I hope this article will help you understand and develop CMS systems!
The above is the detailed content of How to use Python to develop the web page generator function of the CMS system. For more information, please follow other related articles on the PHP Chinese website!

PHP and Python: Code Examples and Comparison
Apr 15, 2025 am 12:07 AM
PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
Python vs. JavaScript: Community, Libraries, and Resources
Apr 15, 2025 am 12:16 AM
Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
How is the GPU support for PyTorch on CentOS
Apr 14, 2025 pm 06:48 PM
Enable PyTorch GPU acceleration on CentOS system requires the installation of CUDA, cuDNN and GPU versions of PyTorch. The following steps will guide you through the process: CUDA and cuDNN installation determine CUDA version compatibility: Use the nvidia-smi command to view the CUDA version supported by your NVIDIA graphics card. For example, your MX450 graphics card may support CUDA11.1 or higher. Download and install CUDAToolkit: Visit the official website of NVIDIACUDAToolkit and download and install the corresponding version according to the highest CUDA version supported by your graphics card.

Detailed explanation of docker principle
Apr 14, 2025 pm 11:57 PM
Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.
