# Settings

Configuration for REST framework is all namespaced inside the `API_SETTINGS` setting.

For example your project's `settings.py` file might look like this:

    API_SETTINGS = {
        'DEFAULT_RENDERERS': (
            'djangorestframework.renderers.YAMLRenderer',
        )
        'DEFAULT_PARSERS': (
            'djangorestframework.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 djangorestframework.settings import api_settings
    
    print api_settings.DEFAULT_AUTHENTICATION

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.

## DEFAULT_RENDERERS

A list or tuple of renderer classes, that determines the default set of renderers that may be used when returning a `Response` object.

Default:

    (
        'djangorestframework.renderers.JSONRenderer',
        'djangorestframework.renderers.DocumentingHTMLRenderer'
        'djangorestframework.renderers.TemplateHTMLRenderer'
    )

## DEFAULT_PARSERS

        'djangorestframework.parsers.FormParser'
    )

## DEFAULT_AUTHENTICATION

A list or tuple of authentication classes, that determines the default set of authenticators used when accessing the `request.user` or `request.auth` properties.

        'djangorestframework.authentication.UserBasicAuthentication'
