Splitting up the settings file
If you use a source control system (CVS, SVN, ...), or want to publish your application on the web, it may be a good idea to move sensitive or machine/user specific settings like database passwords and such out of the main settings.py file.
As discussions on the django-developers mailing list have shown everybody has different requirements and ideas how to do this. This page is ment to collect some of these ideas for future reference.
One thing to keep in mind is that django's config files are pure python. This gives you the ultimate flexibility to handle configurations the way you think is best. Or to quote Adrian Holovaty:
We don't need a default solution for this. It's not within the scope of this project to tell people how they should organize their settings files. Take that opportunity to showcase your individualism.
Different settings in different files
I believe the first user who came up with this was Hugo, who used this method in the projects he published on his site.
SECRET_KEY = open(os.path.expanduser('~/.gallery-secret')).read().strip()
ini-style file for deployment
This is a solution that Michael Radziej posted to django-developers. His motivation was to be able to store the settings for an app he published under /etc with all the other system config files.
[database] DATABASE_USER: bla DATABASE_PASSWORD: XXXXXXXX DATABASE_HOST: dev DATABASE_PORT: DATABASE_ENGINE: mysql DATABASE_NAME: blo TESTSUITE_DATABASE_NAME: test_blo [secrets] SECRET_KEY: random-string-of-ascii CSRF_MIDDLEWARE_SECRET: random-string-of-ascii [cookies] SESSION_COOKIE_DOMAIN: # all settings in debug section should be false in productive environment # INTERNAL_IPS should be empty in productive environment [debug] DEBUG: true TEMPLATE_DEBUG: true VIEW_TEST: true INTERNAL_IPS: 127.0.0.1 SKIP_CSRF_MIDDLEWARE: true [email] SERVER_EMAIL: django@localhost EMAIL_HOST: localhost # the [error mail] and [404 mail] sections are special. Just add lines with # full name: firstname.lastname@example.org # each section must be present but may be empty. [error mail] Adam Smith: adam@localhost [404 mail] John Wayne: john@localhost
from ConfigParser import RawConfigParser config = RawConfigParser() config.read('/etc/whatever/settings.ini') DATABASE_USER = config.get('database', 'DATABASE_USER') DATABASE_PASSWORD = config.get('database', 'DATABASE_PASSWORD') DATABASE_HOST = config.get('database', 'DATABASE_HOST') DATABASE_PORT = config.get('database', 'DATABASE_PORT') DATABASE_ENGINE = config.get('database', 'DATABASE_ENGINE') DATABASE_NAME = config.get('database', 'DATABASE_NAME') TEST_DATABASE_NAME = config.get('database', 'TESTSUITE_DATABASE_NAME') SECRET_KEY = config.get('secrets','SECRET_KEY') CSRF_MIDDLEWARE_SECRET = config.get('secrets', 'CSRF_MIDDLEWARE_SECRET') SESSION_COOKIE_DOMAIN = config.get('cookies','SESSION_COOKIE_DOMAIN') DEBUG = config.getboolean('debug','DEBUG') TEMPLATE_DEBUG = config.getboolean('debug','TEMPLATE_DEBUG') VIEW_TEST = config.getboolean('debug', 'VIEW_TEST') INTERNAL_IPS = tuple(config.get('debug', 'INTERNAL_IPS').split()) if config.getboolean('debug', 'SKIP_CSRF_MIDDLEWARE'): MIDDLEWARE_CLASSES = tuple([x for x in list(MIDDLEWARE_CLASSES) if not x.endswith('CsrfMiddleware')]) SERVER_EMAIL = config.get('email', 'SERVER_EMAIL') EMAIL_HOST = config.get('email', 'EMAIL_HOST') ADMINS = tuple(config.items('error mail')) MANAGERS = tuple(config.items('404 mail'))
Multiple setting files importing from each other
This is my (Steven Armstrong) preferred solution.
Keep application wide, unsensitive settings and sane defaults in your normal settings.py file.
import os BASE_DIR = os.path.dirname(os.path.abspath(__file__)) #PROJECT_DIR = os.path.abspath(os.path.join(BASE_DIR, '..')) PROJECT_DIR = BASE_DIR DEBUG = False TEMPLATE_DEBUG = DEBUG ADMINS = ( ('Mr Sysadmin', 'email@example.com'), ) MANAGERS = ADMINS DATABASE_ENGINE = 'sqlite3' DATABASE_NAME = os.path.join(PROJECT_DIR, 'project.db') DATABASE_USER = '' DATABASE_PASSWORD = '' DATABASE_HOST = '' DATABASE_PORT = '' TIME_ZONE = 'Europe/Zurich' LANGUAGE_CODE = 'en-us' SECRET_KEY = 'secret' #[more default and app wide settings] from settings_local import *
At the end of your normal settings.py include * from an other, machine specific config file which could look something like this.
DEBUG = True TEMPLATE_DEBUG = DEBUG # don't want emails while developing ADMINS = () MANAGERS = ADMINS DATABASE_ENGINE = 'mysql' DATABASE_NAME = 'mydbname' DATABASE_USER = 'mydbuser' DATABASE_PASSWORD = 'mydbpassword' DATABASE_HOST = 'localhost' DATABASE_PORT = '' SECRET_KEY = 'random-string-of-ascii' #[more user/machine specific settings]
settings.py goes into CVS, SVN, (put your favorite RCS here)
settings_local.py does _not_ go under RCS
If wanted a settings_local.template file can be put under version control with instructions to copy it over to settings_local.py, change it to suite the environment, and to never ever commit it to the RCS system.
