# Generic views
> Djangos generic views... were developed as a shortcut for common usage patterns... They take certain common idioms and patterns found in view development and abstract them so that you can quickly write common views of data without having to repeat yourself.
>
> &mdash; [Django Documentation][cite]
One of the key benefits of class based views is the way they allow you to compose bits of reusable behaviour. REST framework takes advantage of this by providing a number of pre-built views that provide for commonly used patterns.
## Example
...

# API Reference
## ListAPIView
Used for read-write endpoints to represent a collection of model instances.
Provides a `get` method handler.
## ListCreateAPIView
Used for read-write endpoints to represent a collection of model instances.
Provides `get` and `post` method handlers.
## RetrieveAPIView
Used for read-only endpoints to represent a single model instance.
Provides a `get` method handler.
## RetrieveUpdateDestroyAPIView
Used for read-write endpoints to represent a single model instance.
Provides `get`, `put` and `delete` method handlers.

# Base views
## BaseAPIView
Extends REST framework's `APIView` class, adding support for serialization of model instances and model querysets.
## MultipleObjectBaseAPIView
Provides a base view for acting on a single object, by combining REST framework's `APIView`, and Django's [MultipleObjectMixin].
**See also:** ccbv.co.uk documentation for [MultipleObjectMixin][multiple-object-mixin-classy].
## SingleObjectBaseAPIView
Provides a base view for acting on a single object, by combining REST framework's `APIView`, and Django's [SingleObjectMixin].
**See also:** ccbv.co.uk documentation for [SingleObjectMixin][single-object-mixin-classy].

# Mixins
The mixin classes provide the actions that are used
## ListModelMixin
Provides a `.list(request, *args, **kwargs)` method, that implements listing a queryset.
## CreateModelMixin
Provides a `.create(request, *args, **kwargs)` method, that implements creating and saving a new model instance.
## RetrieveModelMixin
Provides a `.retrieve(request, *args, **kwargs)` method, that implements returning an existing model instance in a response.
## UpdateModelMixin
Provides a `.update(request, *args, **kwargs)` method, that implements updating and saving an existing model instance.
## DestroyModelMixin
Provides a `.destroy(request, *args, **kwargs)` method, that implements deletion of an existing model instance.
## MetadataMixin
Provides a `.metadata(request, *args, **kwargs)` method, that returns a response containing metadata about the view.
