Share effective techniques for Django version retrieval

Sharing of Django version query skills, specific code examples are required

Django is an efficient Python Web framework that provides developers with fast update iterations. Each new version will bring some new features and improvements, so it is very necessary to master the skills of querying Django version.

In this article, we will share some common Django version query techniques and provide specific code examples.

1. Query version using command

Django provides a command to query the currently installed Django version. Open a terminal or command line and enter the following command:

django-admin --version

After running this command, the currently installed Django version number will be displayed, as shown below:

3.2.7

2. In Python code Query version

In addition to using the command line, we can also query the Django version in Python code. You can get version information by importing the django module and accessing the __version__ attribute. Here is a simple example:

import django

print(django.__version__)

After running the above code, results similar to the following will be output:

3.2.7

3. Query version in Django project

In actual development projects, we may need to query the specific Django version in the Django project. You can use django.__version__ in the settings.py file of the project to obtain Django version information. The following is an example:

from django import __version__

print(__version__)

Place the above code anywhere in the settings.py file and run the Django project, the current Django version number will be output.

4. Testing the functionality of the Django version

Sometimes, we need to perform different operations in the code based on the Django version. You can use the django.VERSION attribute to obtain specific version information, and then perform conditional judgment. The following is an example:

from django import VERSION

if VERSION >= (3, 2):
    print("当前Django版本支持最新功能")
else:
    print("当前Django版本较旧，功能可能有限")

In the above code, we determine whether the current Django version is new enough by comparing the VERSION attribute and the tuple (3, 2).

In summary, we have shared some techniques for querying Django versions and given specific code examples. Mastering these tips can help developers better understand and manage Django versions, so they can better apply new features and improvements.
