Organizing settings in Django

I am working on Django project that uses several dozen configuration variables specified in several "settings" files located in project's root directory: ``` --> myproject ------> app folders ------> ... --- settings.py --- settings_global.py --- settings_production.py --- settings_development.py ``` Variables from different settings_* files are then get imported in settings.py file based on certain run-time parameters (host name etc). It all works rather well, but sometimes it's still hard to locate certain variable, so I'd like re-organize settings variables and split them into several categories: - project-specific variables - django-specific variables - installed-app specific variables (such as settings for django_compressor, etc) - environment-specific variables (production/development) Also I'd like to move all settings files but settings.py file to settings subdirectory: ``` --> myproject ------> app folders ------> ... ------> settings ---------- __init__.py ---------- common.py ---------- production.py ---------- development.py ---------- apps.py ---------- ... --- settings.py ``` I've created settings subdirectory (as well as empty `__init__.py` file) and copied/renamed the settings files. Then I tried to import those variables in my setting.py file as following: ``` from settings.common import * from settings.apps import * ``` However, I am getting the following error (even though ROOT_URLCONF exists in settings/common.py file): ``` AttributeError: 'Settings' object has no attribute 'ROOT_URLCONF' ``` What am I doing wrong?
