  1. Additional features have been added.
  2. Improvements have been made.
  3. The bugs have been fixed.
  4. Updating as each current Django release becomes available reduces the agony of future upgrades by keeping your code up to date
  5. “Long Term Support” (LTS) versions are indicated on some Django framework releases. For three years, LTS versions received security and bug patches. The security risk on your website grows if you use an unsupported version of Django.
  6. It defends your website against cyber-attacks.

How to check the Django Version

You should know which version of Django you’re using before changing the version. There are different ways to check the version of Django.

The first way to find out what the Django version is is to start your Django server if you have created the project. To start the Django server use the following command in your terminal.

python manage.py runserver
how to check django version

The command ‘python manage.py runserver’ starts the Django server and shows the information about the Django server such as on which IP address or port the Django server ‘http://127.0.0.1:8000’ is running.

Also shows the started timing of the Django server ‘February 03, 2022 – 18:09:57’ and the Django version that you can see in the above output something like this ‘Django version 4.0.1’

Now you know the current Django version is 4.0.1. This is the one way to check the version of Django.

The second way is to check the Django version using the freeze command. This freeze command list all the package that you install for your Django project including the Django framework.

So run the below command in your terminal to list all the installed packages within your Django project.

pip freeze

As soon as you run the above command it shows all the packages that you have installed in your environment.

check django version

In the above output, you can see the current version of Django is 4.0.1.

The third way to check the Django version is by using the Python shell. So to open the Python shell type the below command in your terminal.

python manage.py shell

The above command takes you to the Python shell where you can write the Python code. But here you need to know about how to check the Django version. So type the following code in your Python shell.

import django
django.get_version()
how to get django version

In the above code within the python shell, the code import django imports the Django module in the current python shell. Then use the method get_version() of Django to check the current version of installed Django.

As you can see in the output the current version of the Django is 4.0.1.

The fourth and last way to check the Django version is the command that is shown below.

python manage.py version

To acquire the Django version, first, stop the server (if you haven’t already), then open a terminal window and type the command mentioned above.

django version

As you can see in the output, the command ‘python manage.py version’ shows only the version of the currently installed Django which is 4.0.1.

Now you know different ways or methods to check the version of Django, let’s move to the next topic to change the version of the currently installed Django.

Python change Django Version

In this section, you will learn a few possible ways to change the Django version. You can update the Django version to the most recent version or downgrade the Django version to an older version or previous version.

First, let’s see how to update the Django version.

Update Django Version

In many instances, you’ll need to update your Django-related dependencies to the newest version. Some of your dependencies may not yet support the new Django version that was newly released or dependencies aren’t up to date.

In certain cases, you may need to wait until updated versions of your dependencies are released.

Below are three commands that you can run in your terminal or command prompt to update the Django version.

pip install django --upgrade
               #OR
python -m pip install -U django
               #OR
python -m pip install --upgrade django

Open your terminal and check the current version of Django by running the below command.

python manage.py version
python change django version

As you can see the current version of Django is 3.2.12, let’s update the Django version to the latest version.

Open a terminal window and type any of the commands listed above. It will upgrade to the most recent version of Django and uninstall the previous version automatically.

For example, run the below command in your terminal.

python install --upgrade django
python-upgrade-django-version

The outputs demonstrate that it removes the 3.2.12 version and replaces it with the most recent release, 4.0.2. Now you know how to update the Django version.

Let’s move and learn how to downgrade the Django version to an older version.

Downgrade Django Version

Downgrading the Django version is not a good idea, but if there are particular needs that demand it, you can do so. The commands listed below are used to downgrade the version as well as change the version to a specified one.

pip install django==<specific version>
                   #OR
pip install --upgrade django==<specific version>

First, check the current version of Django using the below command.

python manage.py version
python django modify version

As you can see the current version of Django is 4.0.2, so to downgrade the Django version to a specific version such as 3.1.14. Use the below command.

pip install django==3.1.14
python degrade django version

As soon as you hit enter from your keyboard, the current version 4.0.2 of Django is uninstalled and the specific version such as 3.1.14 is installed as you can see in the above output.

pip install --upgrade django==3.2.12
python django specific version

This is how you can change the Django version to a recent and old version. But sometimes you use the IDE for the project development such as Visual Studio, PyCharm, etc.

  • Then double-click on the Django package to open it.
change django version pycharm
  • Select the version you want by checking the box Specify version.
pycharm alter django version
  • Install the package by pressing the Install Package button.
pycharm change django version
  • In the backend, the pip command installs a specific version of Django.

To install a specific version of Django, you can simply use the pip commands that you have learned in the previous sections.
