#29236 closed Bug (fixed)

diffsettings raises misleading exception message if using settings.configure()

Description

If, rather than using the env var DJANGO_SETTINGS_MODULE one uses settings.configure(...), attempting to call diffsettings can fail because it calls settings._setup() unconditionally, with the exception

django.core.exceptions.ImproperlyConfigured: Requested settings, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

were the call instead:

if not settings.configured:
    settings._setup()

things would work correctly.

Keryn I found it difficult to add a test for the patch, since I cannot find a proper way to create the environment needed to catch this case.

On ​https://github.com/django/django/blob/master/tests/admin_scripts/tests.py#L2166, the tests use a target settings file, and if it is not present the tests will fail, so I need to configure somehow the settings, before(?) executing the actual command.

Any proposal or insight?
