coolfig 0.3.0

Installation

pip install coolfig

Example

Define your schema:

from coolfig import Settings, Value, types

class DefaultSettings(Settings):
     SECRET_KEY = Value(str)
     DEBUG = Value(types.boolean, default=False)
     DB_URL = Value(types.sqlalchemy_url)
     LOCALES = Value(types.list(str))

Instantiate the configuration with a data provider:

from coolfig import EnvConfig

settings = DefaultSettings(EnvConfig(prefix='MYAPP_'))

Profit:

if settings.DEBUG:
    print(settings.SECRET_KEY)
else:
    print(settings.LOCALES)

connect(settings.DB_URL)

Django integration

In your settings.py file:

from coolfig import EnvConfig, load_django_settings

INSTALLED_APPS = (
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',

   'testprj.my_custom_app',
)

MIDDLEWARE_CLASSES = (
   'django.contrib.sessions.middleware.SessionMiddleware',
   'django.middleware.common.CommonMiddleware',
   'django.middleware.csrf.CsrfViewMiddleware',
   'django.contrib.auth.middleware.AuthenticationMiddleware',
   'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
   'django.contrib.messages.middleware.MessageMiddleware',
   'django.middleware.clickjacking.XFrameOptionsMiddleware',
   'django.middleware.security.SecurityMiddleware',
)

ROOT_URLCONF = 'testprj.urls'

WSGI_APPLICATION = 'testprj.wsgi.application'

TEMPLATES = [
   {
      'BACKEND': 'django.template.backends.django.DjangoTemplates',
      'DIRS': [],
      'APP_DIRS': True,
      'OPTIONS': {
            'context_processors': [
               'django.template.context_processors.debug',
               'django.template.context_processors.request',
               'django.contrib.auth.context_processors.auth',
               'django.contrib.messages.context_processors.messages',
            ],
      },
   },
]

load_django_settings(EnvConfig(), locals())

Then, in each settings submodule of each app, you can define additional setting entries to be added to the main settings object. For example, in testprj/my_custom_app/settings.py you can add the following:

from coolfig import Settings, Value

class AppSettings(Settings):  # The class has to be named AppSettings
   MY_APP_SETTING = Value(str)

Usage is 100% compatible with Django’s settings machinery:

from django.conf import settings

settings.MY_APP_SETTING
