# Settings > Namespaces are one honking great idea - let's do more of those! > > — [The Zen of Python][cite] 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. --- # API Reference ## DEFAULT_RENDERER_CLASSES A list or tuple of renderer classes, that determines the default set of renderers that may be used when returning a `Response` object. Default: ( 'rest_framework.renderers.JSONRenderer', 'rest_framework.renderers.BrowsableAPIRenderer', 'rest_framework.renderers.TemplateHTMLRenderer' ) ## DEFAULT_PARSER_CLASSES A list or tuple of parser classes, that determines the default set of parsers used when accessing the `request.DATA` property. Default: ( 'rest_framework.parsers.JSONParser', 'rest_framework.parsers.FormParser' ) ## DEFAULT_AUTHENTICATION_CLASSES A list or tuple of authentication classes, that determines the default set of authenticators used when accessing the `request.user` or `request.auth` properties. Default: ( 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.UserBasicAuthentication' ) ## DEFAULT_PERMISSION_CLASSES A list or tuple of permission classes, that determines the default set of permissions checked at the start of a view. Default: ( 'rest_framework.permissions.AllowAny', ) ## DEFAULT_THROTTLE_CLASSES A list or tuple of throttle classes, that determines the default set of throttles checked at the start of a view. Default: `()` ## DEFAULT_MODEL_SERIALIZER_CLASS **TODO** Default: `rest_framework.serializers.ModelSerializer` ## DEFAULT_PAGINATION_SERIALIZER_CLASS **TODO** Default: `rest_framework.pagination.PaginationSerializer` ## FORMAT_SUFFIX_KWARG **TODO** Default: `'format'` ## UNAUTHENTICATED_USER The class that should be used to initialize `request.user` for unauthenticated requests. Default: `django.contrib.auth.models.AnonymousUser` ## UNAUTHENTICATED_TOKEN The class that should be used to initialize `request.auth` for unauthenticated requests. Default: `None` ## FORM_METHOD_OVERRIDE The name of a form field that may be used to override the HTTP method of the form. If the value of this setting is `None` then form method overloading will be disabled. Default: `'_method'` ## FORM_CONTENT_OVERRIDE The name of a form field that may be used to override the content of the form payload. Must be used together with `FORM_CONTENTTYPE_OVERRIDE`. If either setting is `None` then form content overloading will be disabled. Default: `'_content'` ## FORM_CONTENTTYPE_OVERRIDE The name of a form field that may be used to override the content type of the form payload. Must be used together with `FORM_CONTENT_OVERRIDE`. If either setting is `None` then form content overloading will be disabled. Default: `'_content_type'` ## URL_ACCEPT_OVERRIDE The name of a URL parameter that may be used to override the HTTP `Accept` header. If the value of this setting is `None` then URL accept overloading will be disabled. Default: `'accept'` ## URL_FORMAT_OVERRIDE Default: `'format'` [cite]: http://www.python.org/dev/peps/pep-0020/
