django-yamlconf 1.4.0

Define Django settings in local YAML (or JSON) files

django_yamlconf is part of VMware’s support of open source development and community.

Handle YAML based Django settings: load Django settings from YAML files based on a Django project name. The YAML files loaded start with a YAML file in the directory containing the Django settings file and then loads any other YAMLCONF files up the directory tree from the initial file. Values from files higher up the directory tree over-ride lower in the tree. The contents of the YAML file simply defines values that over-ride (or add to) attributes of the standard Django settings file, e.g., for the project “buildaudit”, the settings.py file could contain:

DEBUG = True

i.e., the value for development. This can be redefined via a buildaudit.yaml file using the definition:

DEBUG: false

If the environment variable YAMLCONF_CONFFILE is defined, it uses as the final YAML file loaded (in this case, the file name does not need to match the project name and it can be located anywhere in the file system).

Quick Start

The YAMLCONF definitions are added to the Django settings file by including a call to the load function in the settings file. This would normally be towards the end of the settings file. The simplest, and likely normal usage is to call without arguments. YAMLCONF will infer the project information from the call stack. For a standard Django application structure, the settings file:

myproject/myproject/settings.py

would contain the development oriented definitions, e.g., database definitions for user and password for a development database. The settings file would then end with a call the the load function. Additional definitions could be defined after the load function to update conditional definitions, e.g., if DEBUG is enabled.

import django_yamlconf

...

DATABASES = {
    'default': {
        'NAME': 'example',
        'USER': 'example',
        'PASSWORD': 'example',
        'HOST': 'localhost',
        ...
    }
}
...

django_yamlconf.load()

On a production server, for this example, a myproject.yaml would be put in place containing the host name for the production database and the password for the example user (assuming production is using the same database name and username). In this example, a random pwgen password is used:

DATABASES.default.PASSWORD: 'zibiemohjuD6foh0'
DATABASES.default.HOST: 'myproject-db.eng.vmware.com'

See the load function for more information on other optional arguments.
