#Django versions software
Last but not least, unit test cases are a huge help in preventing errors during routine software development and upgrades. It is easier to develop and deploy software when using tools like source control and Docker, which help minimise environment variations. We are just trying to highlight what all changes we did to achieve the django version migration from 2.2 to 4.2.1 Conclusion:Īlthough upgrading software can be intimidating, there is never a better time to do it than right now because waiting until later will only make it harder and more risky. Note: The changes can be different as per your codebase. At any given time, there could be as many as three supported Django versions available to choose from: previous long-term supported version (LTS) current LTS. import ugettext_lazy changed to import gettext_lazy, etc One of the first things you need to do when starting a new Django project is to choose which version of Django you are going to use._ajax() has been updated to (‘HTTP_X_REQUESTED_WITH’) = ‘XMLHttpRequest’.Some functions has been depreciated and new functions for the same has been implemented like:.Importing some of the plugins from the package.Using django packages like two factor authentication (django-two-factor-auth).Addition of new Fields in models like models.JSONField.Adding base directory to configuration in apps.py with dot operator.These changes are subjected to the codebase and used packages: Let us explain a few changes have been made in the provided codebase to achieve successful versioning and stable functionality.
#Django versions update
Our first approach was migrate the project from django 2.2 to 3.2.15 stable django version supported by Django with securitiesįirstly we review the release notes of the version, fix all deprecation warnings and updated test coverage and then we update the version of Django using pip-tools.Īfter that we upgraded the 3.2.15 to 4.1.1 Django version We followed the “ Divide and conquer” approach to achieve this. Recently we got one request from one of our clients to migrate the django version from 2.2.18 to the latest version 4.2.1.
#Django versions upgrade
In fact, don’t upgrade if there aren’t any unit tests! It would be better to postpone the upgrade and include more unit tests that at least cover half of the project.
#Django versions manual
Without unit tests, the only option for exercising the code is time-consuming manual testing. When attempting upgrades of any kind, unit tests are essential. In our case, we have migrated from Django version 2.2 to 3.2 to 4.1 to 4.2, etc.

That entails upgrading from the existing version to the most stable version that django supports, then moving up to higher versions step by step until you reach your desired version. Follow the Divide and conquer Approach:ĭivide and conquer is the best piece of advice we can give you. By keeping your code base current, upgrading as soon as a new Django release is available makes subsequent upgrades less painful.Ĭheck the supported version: Supported version Read the release note:īefore you attempt an upgrade of a particular Django version, it is prudent to review the release notes for the version that you are upgrading to.Security updates for older Django versions will eventually stop being released.Improvements and new features are included.
#Django versions install
You can now deactivate this environment, activate the other environment, and install Django 1.4 like this: (env)$ pip install Django=1.Upgrading to the most recent Django version offers the following advantages, despite occasionally being a difficult process: This should result in something like: Django=1.0-final You can see if it worked by issuing: (env)$ pip freeze This will install Django version 1.0 inside the current virtual environment. If you have come this far you can start installing environment-specific versions of Python packages like this (in an activated environment): (env)$ pip install Django=1.0 You can leave the virtualenv by typing: (env)$ deactivate Your prompt should indicate that you are running the environment by looking something like this: (env)$ Every time you want to start working with the virtual environment you can issue this command: $ source env/bin/activate If you do so, you get a folder called 'env' which will contain the virtual Python environment. I recommend running this command in the project folder of each app. Once virtualenv is installed you can create separated virtual Python environments, one per Django installation, like this: $ virtualenv env You can install it using: $ easy_install pip If that gives you an error, you probably don't have pip yet. If you don't have virtualenv installed, you can install it like this: $ pip install virtualenv This is how you can check if you already have virtualenv installed: $ virtualenv -version You should definitely go with virtualenv.
