It provides a set of simple decorators that wrap your function based views to ensure they receive an instance of `Request` (rather than the usual Django `HttpRequest`) and allows them to return a `Response` (instead of a Django `HttpResponse`), and allow you to configure how the request is processed. + +### api_view(http_method_names) + +The core of this functionality is the `api_view` decorator, which takes a list of HTTP methods that your view should respond to. For example, this is how you would write a very simple view that just manually returns some data: + + from rest_framework.decorators import api_view + + @api_view(['GET']) + def hello_world(request): + return Response({"message": "Hello, world!"}) + + +This view will use the default renderers, parsers, authentication classes etc specified in the [settings](settings). + +To override the default settings, REST framework provides a set of additional decorators which can be added to your views. These must come *after* (below) the `api_view` decorator. For example, to create a view that uses a [throttle](throttling) to ensure it can only be called once per day by a particular user, use the `throttle_classes` decorator, passing a list of throttle classes: + + from rest_framework.decorators import api_view, throttle_classes + from rest_framework.throttling import UserRateThrottle + + class OncePerDayUserThrottle(UserRateThrottle): + rate = '1/day' + + @api_view(['GET']) + @throttle_classes([OncePerDayUserThrottle]) + def view(request): + return Response({"message": "Hello for today! See you tomorrow!"}) + +These decorators correspond to the attributes set on `APIView` subclasses, described above. + +### renderer_classes(renderer_classes) + +### parser_classes(parser_classes) + +### authentication_classes(authentication_classes) + +### throttle_classes(throttle_classes) + +### permission_classes(permission_classes) -**[TODO]** [cite]: http://reinout.vanrees.org/weblog/2011/08/24/class-based-views-usage.html [cite2]: http://www.boredomandlaziness.org/2012/05/djangos-cbvs-are-not-mistake-but.html +[settings]: api-guide/settings.md +[throttling]: api-guide/throttling.md
