Streamlining Database Changes with Django Evolution

Streamlining Database Changes with Django Evolution

Are you looking for a way to efficiently handle database schema changes in your Django web application? Look no further than Django Evolution, an add-on to the Django web framework that simplifies the management of database changes.

“But wait,” you might ask, “doesn’t Django already have migrations built-in? How is Django Evolution different?”

You’re right! Django does come with migrations, and Django Evolution works alongside them to provide a comprehensive solution. However, there are specific scenarios where Django Evolution shines:

1. Stuck on Django 1.6 or Earlier?

If you’re still using an older version of Django, such as 1.6 or earlier, and need to make changes to your database, Django Evolution is here to help. While newer versions of Django have built-in support for migrations, older codebases may still rely on Django Evolution to manage upgrades. It acts as a bridge to make transitioning to migrations smoother when you eventually upgrade.

2. Upgrading Self-Installable Web Applications

Are you developing a self-installable web application intended for large enterprises? If so, you may have limited control over when your users choose to upgrade. Django’s migrations assume careful planning, where changes to the schema align with the application’s upgrade cadence. However, if customers have the freedom to upgrade on their own schedule, they might accumulate a backlog of migrations spanning years.

This is where Django Evolution shines. It allows you to apply years’ worth of evolutions in a single operation, optimizing the number of table changes needed. The upgrade time can be significantly reduced, taking days, hours, or even seconds off the process.

Supported Versions and Databases

Django Evolution 2.x supports Django 1.6 through 4.2, and Python 2.7 through 3.12. The add-on also provides built-in support for evolving SQLite, Postgres, MySQL, and MariaDB databases.
