[Python-modules-team] Bug#896306: python3-django-imagekit: imagekit fails to import

[Helmut Grohne]

Package: python3-django-imagekit
Version: 4.0.2-1
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python3-django-imagekit importing the module imagekit
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/imagekit/__init__.py", line 2, in <module>
    from . import conf
  File "/usr/lib/python3/dist-packages/imagekit/conf.py", line 6, in <module>
    class ImageKitConf(AppConf):

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

The vast majority of import failures is attributed to missing dependencies.
Often times that manifests as an ImportError or ModuleNotFoundError.
Typically, dependencies should be inserted by dh-python via ${python:Depends}
or ${python3:Depends}. Thus a missing dependency can be caused by incomplete
install_requires in setup.py. Sometimes a missing dependency of a dependency
is the cause, in such cases this bug should be reassigned.
