Django-environ allows you to utilize 12factor inspired environment variables to configure your Django application.
This module is a merge of:
and inspired by:
This is your settings.py file before you have installed django-environ
import os
SITE_ROOT = os.path.dirname(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))
DEBUG = True
TEMPLATE_DEBUG = DEBUG
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'database',
'USER': 'user',
'PASSWORD': 'githubbedpassword',
'HOST': '127.0.0.1',
'PORT': '8458',
}
'extra': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(SITE_ROOT, 'database.sqlite')
}
}
MEDIA_ROOT = os.path.join(SITE_ROOT, 'assets')
MEDIA_URL = 'media/'
STATIC_ROOT = os.path.join(SITE_ROOT, 'static')
STATIC_URL = 'static/'
SECRET_KEY = '...im incredibly still here...'
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': [
'127.0.0.1:11211', '127.0.0.1:11212', '127.0.0.1:11213',
]
},
'redis': {
'BACKEND': 'django_redis.cache.RedisCache',

'OPTIONS': {
'CLIENT_CLASS': 'django_redis.client.DefaultClient',
'PASSWORD': 'redis-githubbed-password',
}
}
}After:
import environ
root = environ.Path(__file__) - 3 # three folder back (/a/b/c/ - 3 = /)
env = environ.Env(DEBUG=(bool, False),) # set default values and casting
environ.Env.read_env() # reading .env file
SITE_ROOT = root()
DEBUG = env('DEBUG') # False if not in os.environ
TEMPLATE_DEBUG = DEBUG
DATABASES = {
'default': env.db(), # Raises ImproperlyConfigured exception if DATABASE_URL not in os.environ
'extra': env.db('SQLITE_URL', default='sqlite:////tmp/my-tmp-sqlite.db')
}
public_root = root.path('public/')
MEDIA_ROOT = public_root('media')
MEDIA_URL = 'media/'
STATIC_ROOT = public_root('static')
STATIC_URL = 'static/'
SECRET_KEY = env('SECRET_KEY') # Raises ImproperlyConfigured exception if SECRET_KEY not in os.environ
CACHES = {
'default': env.cache(),
'redis': env.cache('REDIS_URL')
}You can also pass read_env() an explicit path to the .env file.
Create a .env file:
DEBUG=on
# DJANGO_SETTINGS_MODULE=myapp.settings.dev
SECRET_KEY=your-secret-key
DATABASE_URL=psql://urser:[email protected]:8458/database
# SQLITE_URL=sqlite:///my-local-sqlite.db
CACHE_URL=memcache://127.0.0.1:11211,127.0.0.1:11212,127.0.0.1:11213
REDIS_URL=rediscache://127.0.0.1:6379:1?client_class=django_redis.client.DefaultClient&password=redis-un-githubbed-password$ pip install django-environ
There are only two classes, environ.Env and environ.Path
>>> import environ
>>> env = environ.Env(
DEBUG=(bool, False),
)
>>> env('DEBUG')
False
>>> env('DEBUG', default=True)
True
>>> open('.myenv', 'a').write('DEBUG=on')
>>> environ.Env.read_env('.myenv') # or env.read_env('.myenv')
>>> env('DEBUG')
True
>>> open('.myenv', 'a').write('\nINT_VAR=1010')
>>> env.int('INT_VAR'), env.str('INT_VAR')
1010, '1010'
>>> open('.myenv', 'a').write('\nDATABASE_URL=sqlite:///my-local-sqlite.db')
>>> env.read_env('.myenv')
>>> env.db()
{'ENGINE': 'django.db.backends.sqlite3', 'NAME': 'my-local-sqlite.db', 'HOST': '', 'USER': '', 'PASSWORD': '', 'PORT': ''}
>>> root = env.path('/home/myproject/')
>>> root('static')
'/home/myproject/static'- str

In order to set email configuration for django you can use this code:
EMAIL_CONFIG = env.email_url(
'EMAIL_URL', default='smtp://user@:password@localhost:25')
vars().update(EMAIL_CONFIG)$ git clone [email protected]:joke2k/django-environ.git $ cd django-environ/ $ python setup.py test
