setting has no attribute ROOT_URLCONF error while running app with virtualenv

Question

I'm getting an error while making a request to Django devserver (it is running in virtual environment dj_venv):

[19/Jul/2016 11:32:40] "GET / HTTP/1.1" 500 59
Traceback (most recent call last):
  File "/usr/lib/python2.7/wsgiref/handlers.py", line 85, in run
    self.result = application(self.environ, self.start_response)
  File "/home/daria/venvs/dj_venv/local/lib/python2.7/site-packages/django/contrib/staticfiles/handlers.py", line 67, in __call__
    return self.application(environ, start_response)
  File "/home/daria/venvs/dj_venv/local/lib/python2.7/site-packages/django/core/handlers/wsgi.py", line 241, in __call__
    response = self.get_response(request)
  File "/home/daria/venvs/dj_venv/local/lib/python2.7/site-packages/django/core/handlers/base.py", line 82, in get_response
    urlconf = settings.ROOT_URLCONF
  File "/home/daria/venvs/dj_venv/local/lib/python2.7/site-packages/django/utils/functional.py", line 185, in inner
    return func(self._wrapped, *args)
AttributeError: 'Settings' object has no attribute 'ROOT_URLCONF'

The weird thing is that when I start server and don't make any request, I don't get any errors:

daria@daria:~/cms.media$ . ../venvs/dj_venv/bin/activate

(dj_venv) daria@daria:~/cms.media$ python manage.py runserver Validating models...

0 errors found Django version 1.4.11, using settings 'apps.settings' Development server is running at http://127.0.0.1:8000/ Quit the server with CONTROL-C.

But after the first request I get an AttributeError as presented above.

I understand that this error is thrown because my settings object has no attribute 'ROOT_URLCONF', but I have defined it in settings.py and in global_settings.py of my virtual environment. I also looked at these articles:

Official docs (ROOT_URLCONF option and how Django processes a request)
Related topics:

And I checked these points:

DJANGO_SETTING_MODULE is defined in manage.py (points to apps.settings)
ROOT_URLCONF is defined in settings.py (points to outer urls.py in apps folder)
DJANGO_SETTING_MODULE and ROOT_URLCONF added to PyCharm's Run > Edit Configuration > Environment variables

There is Environment variables:

DEFAULT_INDEX_TABLESPACE=1
DJANGO_SETTINGS_MODULE=apps.settings
PYTHONUNBUFFERED=1
ROOT_URLCONF=urls

There is my project structure:

What may be the reason of that exception? I have tried all that I found in stackoverflow. I guess the reason may be in wrong references to settings.py or ROOT_URLCONF, I have tried various choices but I am still getting the Attribute error.

And also I guess that the reason could be in middleware which may redefine ROOT_URLCONF while the server is performing a request (because it is ok before I wouldn't make any request to server), but I don't know where I can fix it.

Am I right in my guesses? And if yes, how can I solve my problem? Hope for any help!
