# Settings
|

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

|
|
|
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.
