# Views
|
|
|
|
REST framework provides a simple `APIView` class, built on Django's `django.generics.views.View`. The `APIView` class ensures five main things:
|
|
|
|
1. Any requests inside the view will become `Request` instances.
|
|
2. `Request` instances will have their `renderers` and `authentication` attributes automatically set.
|
|
3. `Response` instances will have their `parsers` and `serializer` attributes automatically set.
|
|
4. `APIException` exceptions will be caught and return appropriate responses.
|
|
5. Any permissions provided will be checked prior to passing the request to a handler method.
|
|
|
|
Additionally there are a some minor extras, such as providing a default `options` handler, setting some common headers on the response prior to return, and providing the useful `initial()` and `final()` hooks.
