How to delete a Django application
==================================

Django provides the ability to group sets of features into Python packages
called :doc:`applications</ref/applications/>`. When requirements change, apps
may become obsolete or unnecessary. The following steps will help you delete an
application safely.

#. Remove all references to the app (imports, foreign keys etc.).

#. Remove all models from the corresponding ``models.py`` file.

#. Create relevant migrations by running :djadmin:`makemigrations`. This step
   generates a migration that deletes tables for the removed models, and any
   other required migration for updating relationships connected to those
   models.

#. :ref:`Squash <migration-squashing>` out references to the app in other apps'
   migrations.

#. Apply migrations locally, runs tests, and verify the correctness of your
   project.

#. Deploy/release your updated Django project.

#. Remove the app from :setting:`INSTALLED_APPS`.

#. Finally, remove the app's directory.
