Build a blog website using the Python Django framework
With the popularity of the Internet, blogs play an increasingly important role in information dissemination and communication. In this context, more and more people are starting to build their own blog sites. This article will introduce how to use the Python Django framework to build your own blog website.
1. Introduction to Python Django framework
Python Django is a free and open source web framework that can be used to quickly develop web applications. The framework provides developers with powerful tools that help them build feature-rich web applications. The Django framework has a rigorous architecture and fully considers the developer's experience.
2. Preparation
Before you start building a blog website, you need to prepare the following tools in advance:
- Python
Python It is a powerful programming language suitable for the development of various applications. The Django framework is developed in Python, so Python needs to be installed first.
- PIP
PIP is a Python package manager that can be used to install and manage Python libraries. It is recommended to use PIP for component installation when configuring the Python development environment.
- Django
Django is a web framework written in Python that is designed to help developers build web applications more easily. Django can be installed using PIP.
3. Create a Django project
- Create a Django project
Use the command line to open the working directory (such as "D: log"), and then run The following command is used to create a Django project:
$ django-admin startproject myblog
After entering the above command at the command line, Django will create a new directory named "myblog", which contains some files and folders required to start the web application.
- Create a Django application
Go to the myblog directory on the command line and run the following command to create a new Django application:
$ python manage.py startapp myapp
In this step, Django creates a new folder named "myapp" in the myblog directory, which contains the necessary files and folders for the application.
4. Writing a Blog Application
- Writing Views
Open the myapp directory, find the views.py file, and then add the following code to the file ：
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world. Welcome to my blog!")In the above code, we use Django's render function to respond to an HTTP request.
- Write URL routing
Open the urls.py file in the myapp directory and add the following code:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
]This code will make an HTTP request Pointing to the "/" path, the request will be handled by the index view function in myapp.
- Writing Templates
The Django framework supports the use of templates to increase application reusability and flexibility. Templates are HTML files that contain dynamic content in views.
Create a new folder named "templates" in the myapp directory, and then create an HTML file named "index.html" in the folder. Add the following code in the file:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to my blog</title>
</head>
<body>
<h1>Welcome to my blog</h1>
</body>
</html>In the above code, we have created a simple HTML page with the title "Welcome to my blog". This page will be used as the blog's home page.
5. Start the Django project
Enter the following command on the command line to start the Django project:
$ python manage.py runserver
After startup, enter "http://127.0.0.1" in the browser :8000/” to view the homepage of the blog website. At this point, the blog site we see is still very simple, but as more features are added, the blog site will look different.
6. Summary
This article introduces how to use the Python Django framework to build a blog website. We built this blog website step by step from project creation, to application writing, to rendering dynamic content on HTML pages through templates. Such a blog website is a basic version, and developers can extend it by adding more features, such as adding blog posts, comments, etc.

PHP calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.
How to use PHP combined with AI to achieve text error correction PHP syntax detection and optimization
Jul 25, 2025 pm 08:57 PM
To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X

Any type list can be directly converted to strings with brackets and quotes, suitable for debugging; 4. Custom formats can be implemented by generator expressions combined with join(), such as '|'.join(f"[{item}]"foriteminitems) output"[a]|[

pandas.melt() is used to convert wide format data into long format. The answer is to define new column names by specifying id_vars retain the identification column, value_vars select the column to be melted, var_name and value_name, 1.id_vars='Name' means that the Name column remains unchanged, 2.value_vars=['Math','English','Science'] specifies the column to be melted, 3.var_name='Subject' sets the new column name of the original column name, 4.value_name='Score' sets the new column name of the original value, and finally generates three columns including Name, Subject and Score.

python django forms example
Jul 27, 2025 am 02:50 AM
First, define a ContactForm form containing name, mailbox and message fields; 2. In the view, the form submission is processed by judging the POST request, and after verification is passed, cleaned_data is obtained and the response is returned, otherwise the empty form will be rendered; 3. In the template, use {{form.as_p}} to render the field and add {%csrf_token%} to prevent CSRF attacks; 4. Configure URL routing to point /contact/ to the contact_view view; use ModelForm to directly associate the model to achieve data storage. DjangoForms implements integrated processing of data verification, HTML rendering and error prompts, which is suitable for rapid development of safe form functions.
