How to choose Django version? A guide to help you make smart choices

Django is an open source web framework written using the Python programming language. Django has a high degree of flexibility, scalability and reusability, and is widely used in the field of web development.

As Django continues to develop, multiple versions have appeared. Choosing the right version is very important for developers. This article will introduce several noteworthy points and provide specific code examples to help you choose the appropriate Django version.

1. Python version

Different versions of Django have different dependencies on Python. Before choosing a Django version, you need to determine whether the Python version you are using is compatible with the Django version.

Django 1.x series requires Python 2.7.x version. Starting from Django2.x, Python 3.4 and above can be used. Therefore, the first step in choosing a Django version is to see if the Python version you are using meets the requirements.

2. Long-term support version (LTS) and non-LTS version

The long-term support version (LTS) means that the Django development team will provide support and updates for 5 years, while the non-LTS version only provides Support and updates until the next major version release.

Generally speaking, choosing the LTS version is a wiser choice, especially for developers who pay more attention to security and stability. However, LTS versions may not have the latest features and libraries.

Currently, the LTS version of Django is 2.2. If developers need more new features and libraries, they can consider choosing the latest version.

3. Version release time

The release time of different versions of Django also needs to be considered. Versions released within one year may have some bugs. Before selecting a version, you can check the change log and community discussion of the version to see whether there are obvious problems with the version.

4. Third-party library support

The Django version is updated very quickly, and many third-party libraries will be updated soon. However, older Django versions may not support some of the latest third-party libraries. Therefore, before choosing a Django version, make sure that the third-party library used is compatible with that Django version.

Now, let’s see how to choose the appropriate Django version through a code example. The following examples are based on Django 2.2 and 3.1:

Django 2.2 example:

python -m pip install Django==2.2

Django 3.1 example:

python -m pip install Django==3.1

As mentioned above, you first need to ensure that the Python version you are using matches the Django version Require. Then use the pip command to install the Django version of your choice.

Choosing the appropriate Django version is very important. Through the guidance and code examples provided in this article, developers can ensure that they choose the appropriate Django version and that the Python version and third-party libraries they use are compatible with that Django version.
