#15336 closed (fixed)

Spurious DeprecationWarning when no database settings present

Description

If a db-less project doesn't set up database settings management commands produce a spurious DeprecationWarning:

django/db/__init__.py:18: DeprecationWarning: settings.DATABASE_* is deprecated; use settings.DATABASES instead.
  DeprecationWarning

This breaks running cron scripts due to cron considering any output from a program as a reason to yell into your email about something possibly broken.

The warning is raised on a single condition of empty settings.DATABASES. This is easily fixed by also checking if a deprecated settings.DATABASE_ENGINE is set. A patch is following.

Has patch: set

I'm not really sure how to write a test for this because tests require database settings. However the fix seems to be pretty trivial and may be we could leave out tests in this case.

This is inherently difficult to test, so I'm happy to accept this RFC based on inspection and manual testing.
