The trick here will be to keep the settings.py file containing all default values. Then, we'll create one file per environment that will get the settings.py values, and might override them, or add new (could even delete I guess). As we'll have multiple config files, we'll package them:
/project/conf /__init__.py /settings.py /local.py /staging.py /prod.py
Your settings.py file will keep the default and customized values as usual. Other 3 files will have same content as below (all 3 similar).
from conf.settings import * DEBUG = True TEMPLATE_DEBUG = DEBUG OTHER_VAR = "value in local"
You should update these 2 files accordingly. manage.py will obviously refer to local.py :
Point your DJANGO_SETTINGS_MODULE to conf.local :
#!/usr/bin/env python import os if __name__ == "__main__": os.environ.setdefault("DJANGO_SETTINGS_MODULE", "conf.local") from django.core.management import execute_from_command_line execute_from_command_line(sys.argv)
Set DJANGO_SETTINGS_MODULE to conf.staging or conf.prod depending on wich environment will call it :
import os os.environ.setdefault("DJANGO_SETTINGS_MODULE", "conf.staging") from django.core.wsgi import get_wsgi_application application = get_wsgi_application()
Yes, that's all working already !
Some apps such as django-debug-toolbar should be installed and configured in local environment only. Here's how :
/project/conf/local.py : INSTALLED_APPS += ('debug_toolbar',) MIDDLEWARE_CLASSES += ('debug_toolbar.middleware.DebugToolbarMiddleware',)
In most Django code you can read at the bottom of urls.py file something like :
if settings.DEBUG is True: urlpatterns += patterns('', (r"^static/(?P<path>.*)/?$", 'some.static.views') )
That's great, that doesn't load that url if we did not activate DEBUG. But that's really tricky !
In /projects/conf/local.py, add :
… ROOT_URLCONF = 'app.urls_local'
And create a app/urls_local.py (or path accordingly), containing :
from urls import * urlpatterns += patterns('', (r"^static/(?P<path>.*)/?$", 'some.static.views') )
(change "from urls …" accordingly to whatever package matches your urls.py file).
