Django composable settings loader.

Project description

We are under CI!!

Aims to compose your settings from python modules and python scripts in /etc.

In your my_app/settings/__init__.py call the loader:

from django_compose_settings import modules_loader

locals().update(modules_loader(prefix='my_app', default='base,etc,post'))

In my_app/settings/base.py define default values as usual, ex:

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

# ...

In my_app/settings/etc.py call the etc loader:

from django_compose_settings import etc_loader

locals().update(etc_loader(prefix='my_app'))

You can validate settings in my_app/settings/post.py as follow:

import __settings__

assert hasattr(__settings__, 'BASE_DIR'), 'BASE_DIR required'

Etc settings

Here is a sample tree of your /etc/my_app:

/etc/my_app/
├── settings.d
│   ├── 00_prod1.py
│   └── 99_local.py
└── settings.py

Each .py file is a regular composable settings file as post.py above.

MY_APP_SETTINGS

You can override your settings with a specific SETTINGS environment variable for your app as follow:

$ MY_APP_SETTINGS=base,post python

>>> import logging
>>> logging.basicConfig(
...     level=logging.INFO,
...     format='%(asctime)s %(levelname)-8s %(name)s  %(message)s'
... )

>>> import os
>>> import sys
>>> sys.path.append(os.path.join(os.path.abspath('tests'), 'fixtures'))

>>> from my_app import settings
