Detailed Guide: The Accurate Way to Check Django Version

In-depth analysis of how to accurately view the Django version requires specific code examples

Introduction:
Django, as a popular Python web framework, often requires version management and upgrade. However, sometimes it may be difficult to check the Django version number in the project, especially when the project has entered the production environment, or uses a large number of custom extensions and partial modules. This article will introduce in detail how to accurately check the version of the Django framework, and provide some code examples to help developers better manage Django versions.

1. How to check the Django version

1. Use the command line tool: Django provides a command line tool django-admin, we can use it to check version number. Using the command django-admin --version will return the current version number of Django.
2. Using Python code: We can also get the Django version number by importing Django in the Python code. The specific implementation method is as follows:

import django

print(django.get_version())

In the above code, we use Django’s get_version() function to get the current Django version number, and then use printThe function outputs it.

3. View Django source code: If necessary, we can also confirm the version by directly viewing the Django source code. We can obtain the Django source code through the following steps:

• Visit Django’s official website https://www.djangoproject.com/, and choose to download the appropriate Django version compressed package on the download page .
• Unzip the downloaded compressed package, and we can find the folder structure inside the compressed package, which contains various versions of Django source code files.
• Search and open the django/__init__.py file in the decompressed folder, which will contain the current version of Django information.

2. Code examples and instructions
In order to better understand how to view the Django version, we provide some code examples for demonstration.

Example 1: Use the command line tool to view the Django version
We can run the following command in the command line to view the Django version number:

django-admin --version

Example 2: Use Python code to view Django Version
We can write a simple Python script to check the version number of Django. The code is as follows:

import django

print(django.get_version())

When we run this code, the current Django version number will be output.

Example 3: View the version information in the Django source code
We can learn the details of the current version by viewing the Django source code.
First, we need to download and unzip the appropriate Django source code version. Then, open the decompressed folder and perform the following operations:

• Search and open the django/__init__.py file in the folder.
• In the __init__.py file, you can find variables containing current Django version information.

VERSION = (3, 2, 5, 'final', 0)

def get_version():
    """Return the Django version as a string."""
    return get_version_string(VERSION)

In the above sample code, we can see that the current Django version is 3.2.5.

Conclusion:
Through the introduction of this article, we have an in-depth analysis of how to accurately check the Django version. We can obtain the Django version number through command line tools, Python code, and viewing Django source code. This is very important for project management and maintenance, especially when doing version iterations and upgrades. I hope this article will help everyone to better manage and use Django.
