Description:

djangoenvconfig 0.3.1

django-envconfig

Configure Django using environment variables (envvars). settings.py optional.
Getting started
Installation
python -m pip install django-envconfig

Usage
Edit the manage.py, asgi.py and wsgi.py files generated by Django's
startproject command and modify the following line:
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'envconfig.settings')

Minimum configuration
The following envvars are required (if settings.py is removed):

ALLOWED_HOSTS (unless you set DEBUG=on)

Environments may be stored in an .env file. This file can be stored in your
root directory (next to manage.py) or anywhere on the path (e.g. virtualenv
directory).
How it works
Any Django setting can
be configured as an environment variable.

To set booleans: true|yes|on|1 and false|no|off|0 (case-insensitive)
To set None: none|null (case-insensitive)
Simple lists of strings can be stored comma-separated e.g. export ALLOWED_HOSTS=127.0.0.1,localhost
Dicts and complex lists should be stored as JSON

Settings are loaded with the following priority (highest first):

Environment variables.
Settings defined in your projects settings.py, if it exists. Note: any
custom settings should be defined here with their default value.
Settings that would be defined by a settings.py file generated by
startproject. This should eliminate the need for the file in (2) for most
projects. Caveats:

The default value for DEBUG has been changed to False.
A SECRET_KEY is generated but will not persist between sessions (e.g.
if you restart your server/process manager). Check the
Django documentation
to see whether you need to set a persistent SECRET_KEY as an
environment variable.

PostgreSQL environment variables
If you are using a PostgreSQL backend you do not need to set DATABASES. You
can simply set PostgreSQL environment variables - the minimum is PGDATABASE.
See the
PostgreSQL docs
for the full list of envvars. This way the same environment can be used when
calling
PostgreSQL command line utilities
such as psql or pg_dump.
Why

To separate configuration from code. See
The Twelve Factor App.
Use serverless services such as AWS Lambda and Heroku.
Avoid having to template settings files and keep the auto-generated
settings.py up to date between Django versions.
Use .env files for easy switching between environments/deployments
(e.g. dev, test and prod).
