Settings

Namespaces are one honking great idea - let's do more of those!

— The Zen of Python

Configuration for REST framework is all namespaced inside a single Django setting, named REST_FRAMEWORK.

For example your project's settings.py file might include something like this:

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.YAMLRenderer',
    ),
    'DEFAULT_PARSER_CLASSES': (
        'rest_framework.parsers.YAMLParser',
    )
}

Accessing settings

If you need to access the values of REST framework's API settings in your project, you should use the api_settings object. For example.

from rest_framework.settings import api_settings

print api_settings.DEFAULT_AUTHENTICATION_CLASSES

The api_settings object will check for any user-defined settings, and otherwise fallback to the default values. Any setting that uses string import paths to refer to a class will automatically import and return the referenced class, instead of the string literal.
