Django-environ
==============

Django-environ allows you to utilize 12factor inspired environment variables to configure your Django application.

|pypi| |unix_build| |windows_build| |coverage| |license|


This module is a merge of:

* `envparse`_
* `honcho`_
* `dj-database-url`_
* `dj-search-url`_
* `dj-config-url`_
* `django-cache-url`_

and inspired by:

* `12factor`_
* `12factor-django`_
* `Two Scoops of Django`_

This is your `settings.py` file before you have installed **django-environ**

.. code-block:: python

    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',
            'LOCATION': '127.0.0.1:6379/1',
            'OPTIONS': {
                'CLIENT_CLASS': 'django_redis.client.DefaultClient',
                'PASSWORD': 'redis-githubbed-password',
            }
        }
    }

After:

.. code-block:: python

    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:

.. code-block:: bash

    DEBUG=on
    # DJANGO_SETTINGS_MODULE=myapp.settings.dev
    SECRET_KEY=your-secret-key
    DATABASE_URL=psql://urser:un-githubbedpassword@127.0.0.1:8458/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


How to install
==============

::

    $ pip install django-environ


How to use
==========

There are only two classes, ``environ.Env`` and ``environ.Path``

.. code-block:: python

    >>> 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'


See `cookiecutter-django`_ for a concrete example on using with a django project.

Tips
====

Using unsafe characters in URLs
-------------------------------

In order to use unsafe characters you have to encode with ``urllib.parse.encode`` before you set into ``.env`` file.

.. code-block::

    DATABASE_URL=mysql://user:%23password@127.0.0.1:3306/dbname


See https://perishablepress.com/stop-using-unsafe-characters-in-urls/ for reference.

Multiple redis cache locations
------------------------------

For redis cache, `multiple master/slave or shard locations <http://niwinz.github.io/django-redis/latest/#_pluggable_clients>`_ can be configured as follows:

.. code-block::

    CACHE_URL='rediscache://master:6379,slave1:6379,slave2:6379/1'

Email settings
--------------

In order to set email configuration for django you can use this code:

.. code-block:: python

    EMAIL_CONFIG = env.email_url(
        'EMAIL_URL', default='smtp://user@:password@localhost:25')

    vars().update(EMAIL_CONFIG)


SQLite urls
-----------

SQLite connects to file based databases. The same URL format is used, omitting the hostname,
and using the "file" portion as the filename of the database.
This has the effect of four slashes being present for an absolute
file path: sqlite:////full/path/to/your/database/file.sqlite.
