PROD - QUEUE - DJANGO_SETTINGS_MODULE is undefined

[Amine Azariz]

I am using Django 1.2, Python 2.5. This error happens from time to time. - e.g. some tasks got this error, some - not.

How to solve this one?

File "/base/python_runtime/python_lib/versions/third_party/django-1.2/django/template/loader.py", line 168, in get_template_from_string
    return Template(source, origin, name)
  File "/base/python_runtime/python_lib/versions/third_party/django-1.2/django/template/__init__.py", line 156, in __init__
    if settings.TEMPLATE_DEBUG and origin is None:
  File "/base/python_runtime/python_lib/versions/third_party/django-1.2/django/utils/functional.py", line 276, in __getattr__
    self._setup()
  File "/base/python_runtime/python_lib/versions/third_party/django-1.2/django/conf/__init__.py", line 38, in _setup
    raise ImportError("Settings cannot be imported, because environment variable %s is undefined." % ENVIRONMENT_VARIABLE)
ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.

Define the DJANGO_SETTINGS_MODULE environment variable in your app.yaml config.

https://developers.google.com/appengine/docs/python/config/appconfig#env_variables

This will ensure it's always available to any entry point that's handling a request.

I sometimes see this on dev_appserver when I use the datastore admin page locally, afterwards I usually need to reset the dev_appserver.  It doesn't cause a problem on production, but I'll give Matt's suggestion a try.
