 # API Reference
 
+## GenericAPIView
+
+This class extends REST framework's `APIView` class, adding commonly required behavior for standard list and detail views.
+
+Each of the concrete generic views provided is built by combining `GenericAPIView`, with one or more mixin classes.
+
+### Attributes
+
+**Basic settings**:
+
+The following attributes control the basic view behavior.
+
+* `queryset` - The queryset that should be used for returning objects from this view.  Typically, you must either set this attribute, or override the `get_queryset()` method.
+* `serializer_class` - The serializer class that should be used for validating and deserializing input, and for serializing output.  Typically, you must either set this attribute, or override the `get_serializer_class()` method.
+* `lookup_field` - The field that should be used to lookup individual model instances.  Defaults to `'pk'`.  The URL conf should include a keyword argument corresponding to this value.  More complex lookup styles can be supported by overriding the `get_object()` method.
+
+**Shortcuts**:
+
+* `model` - This shortcut may be used instead of setting either (or both) of the `queryset`/`serializer_class` attributes, although using the explicit style is generally preferred.  If used instead of `serializer_class`, then then `DEFAULT_MODEL_SERIALIZER_CLASS` setting will determine the base serializer class.
+
+**Pagination**:
+
+The following attibutes are used to control pagination when used with list views.
+
+* `paginate_by` - The size of pages to use with paginated data.  If set to `None` then pagination is turned off.  If unset this uses the same value as the `PAGINATE_BY` setting, which defaults to `None`.
+* `paginate_by_param` - The name of a query parameter, which can be used by the client to overide the default page size to use for pagination.  If unset this uses the same value as the `PAGINATE_BY_PARAM` setting, which defaults to `None`.
+* `pagination_serializer_class` - The pagination serializer class to use when determining the style of paginated responses.  Defaults to the same value as the `DEFAULT_PAGINATION_SERIALIZER_CLASS` setting.
+* `page_kwarg` - The name of a URL kwarg or URL query parameter which can be used by the client to control which page is requested.  Defaults to `'page'`.
+
+**Filtering**:
+
+* `filter_backends` - A list of filter backend classes that should be used for filtering the queryset.  Defaults to the same value as the `DEFAULT_FILTER_BACKENDS` setting.
+
+### Methods
+
+**Base methods**:
+
+#### `get_queryset(self)`
+
+Returns the queryset that should be used for list views, and that should be used as the base for lookups in detail views.  Defaults to returning the queryset specified by the `queryset` attribute, or the default queryset for the model if the `model` shortcut is being used.
+
+May be overridden to provide dynamic behavior such as returning a queryset that is specific to the user making the request.
+
+For example:
+
+    def get_queryset(self):
+        return self.user.accounts.all()
+
+#### `get_object(self)`
+
+Returns an object instance that should be used for detail views.  Defaults to using the `lookup_field` parameter to filter the base queryset.
+
+May be overridden to provide more complex behavior such as object lookups based on more than one URL kwarg.
+
+For example:
+
+    def get_object(self):
+        queryset = self.get_queryset()
+        filter = {}
+        for field in self.multiple_lookup_fields:
+            filter[field] = self.kwargs[field]
+        return get_object_or_404(queryset, **filter)
+
+#### `get_serializer_class(self)`
+
+Returns the class that should be used for the serializer.  Defaults to returning the `serializer_class` attribute, or dynamically generating a serializer class if the `model` shortcut is being used.
+
+May be override to provide dynamic behavior such as using different serializers for read and write operations, or providing different serializers to different types of uesr.
+
+For example:
+
+    def get_serializer_class(self):
+        if self.request.user.is_staff:
+            return FullAccountSerializer
+        return BasicAccountSerializer
+
+#### `get_paginate_by(self)`
+
+Returns the page size to use with pagination.  By default this uses the `paginate_by` attribute, and may be overridden by the cient if the `paginate_by_param` attribute is set.
+
+You may want to override this method to provide more complex behavior such as modifying page sizes based on the media type of the response.
+
+For example:
+
+    def get_paginate_by(self):
+        self.request.accepted_renderer.format == 'html':
+            return 20
+        return 100
+
+**Save hooks**:
+
+The following methods are provided as placeholder interfaces.  They contain empty implementations and are not called directly by `GenericAPIView`, but they are overridden and used by some of the mixin classes.
+
+* `pre_save(self, obj)` - A hook that is called before saving an object.
+* `post_save(self, obj, created=False)` - A hook that is called after saving an object.
+
+The `pre_save` method in particular is a useful hook for setting attributes that are implicit in the request, but are not part of the request data.  For instance, you might set an attribute on the object based on the request user, or based on a URL keyword argument.
+
+    def pre_save(self, obj):
+        """
+        Set the object's owner, based on the incoming request.
+        """
+        obj.owner = self.request.user
+
+Remember that the `pre_save()` method is not called by `GenericAPIView` itself, but it is called by `create()` and `update()` methods on the `CreateModelMixin` and `UpdateModelMixin` classes.
+
+**Other methods**:
+
+You won't typically need to override the following methods, although you might need to call into them if you're writing custom views using `GenericAPIView`.
+
+* `get_serializer_context(self)` - Returns a dictionary containing any extra context that should be supplied to the serializer.  Defaults to including `'request'`, `'view'` and `'format'` keys.
+* `get_serializer(self, instance=None, data=None, files=None, many=False, partial=False)` - Returns a serializer instance.
+* `get_pagination_serializer(self, page)` - Returns a serializer instance to use with paginated data.
+* `paginate_queryset(self, queryset)` - Paginate a queryset if required, either returning a page object, or `None` if pagination is not configured for this view.
+* `filter_queryset(self, queryset)` - Given a queryset, filter it with whichever filter backend is in use, returning a new queryset.
+

+# Routers
+
+> Resource routing allows you to quickly declare all of the common routes for a given resourceful controller. Instead of declaring separate routes for your index... a resourceful route declares them in a single line of code.
+>
+> &mdash; [Ruby on Rails Documentation][cite]
+
+Some Web frameworks such as Rails provide functionality for automatically determining how the URLs for an application should be mapped to the logic that deals with handling incoming requests.
+
+REST framework adds support for automatic URL routing to Django, and provides you with a simple, quick and consistent way of wiring your view logic to a set of URLs.
+
+## Usage
+
+Here's an example of a simple URL conf, that uses `DefaultRouter`.
+
+    router = routers.SimpleRouter()
+    router.register(r'users', UserViewSet)
+    router.register(r'accounts', AccountViewSet)
+    urlpatterns = router.urls
+
+There are two mandatory arguments to the `register()` method:
+
+* `prefix` - The URL prefix to use for this set of routes.
+* `viewset` - The viewset class.
+
+Optionally, you may also specify an additional argument:
+
+* `base_name` - The base to use for the URL names that are created.  If unset the basename will be automatically generated based on the `model` or `queryset` attribute on the viewset, if it has one.
+
+The example above would generate the following URL patterns:
+
+* URL pattern: `^users/$`  Name: `'user-list'`
+* URL pattern: `^users/{pk}/$`  Name: `'user-detail'`
+* URL pattern: `^accounts/$`  Name: `'account-list'`
+* URL pattern: `^accounts/{pk}/$`  Name: `'account-detail'`
+
+### Extra link and actions
+
+Any methods on the viewset decorated with `@link` or `@action` will also be routed.
+For example, a given method like this on the `UserViewSet` class:
+
+    @action(permission_classes=[IsAdminOrIsSelf])
+    def set_password(self, request, pk=None):
+        ...
+
+The following URL pattern would additionally be generated:
+
+* URL pattern: `^users/{pk}/set_password/$`  Name: `'user-set-password'`
+
+# API Guide
+
+## SimpleRouter
+
+This router includes routes for the standard set of `list`, `create`, `retrieve`, `update`, `partial_update` and `destroy` actions.  The viewset can also mark additional methods to be routed, using the `@link` or `@action` decorators.
+
+<table border=1>
+    <tr><th>URL Style</th><th>HTTP Method</th><th>Action</th><th>URL Name</th></tr>
+    <tr><td rowspan=2>{prefix}/</td><td>GET</td><td>list</td><td rowspan=2>{basename}-list</td></tr></tr>
+    <tr><td>POST</td><td>create</td></tr>
+    <tr><td rowspan=4>{prefix}/{lookup}/</td><td>GET</td><td>retrieve</td><td rowspan=4>{basename}-detail</td></tr></tr>
+    <tr><td>PUT</td><td>update</td></tr>

+    <tr><td>POST</td><td>@action decorated method</td></tr>
+</table>
+
+## DefaultRouter
+
+This router is similar to `SimpleRouter` as above, but additionally includes a default API root view, that returns a response containing hyperlinks to all the list views.  It also generates routes for optional `.json` style format suffixes.
+
+<table border=1>
+    <tr><th>URL Style</th><th>HTTP Method</th><th>Action</th><th>URL Name</th></tr>
+    <tr><td>[.format]</td><td>GET</td><td>automatically generated root view</td><td>api-root</td></tr></tr>

+    <tr><td>POST</td><td>create</td></tr>
+    <tr><td rowspan=4>{prefix}/{lookup}/[.format]</td><td>GET</td><td>retrieve</td><td rowspan=4>{basename}-detail</td></tr></tr>
+    <tr><td>PUT</td><td>update</td></tr>
+    <tr><td>PATCH</td><td>partial_update</td></tr>
+    <tr><td>DELETE</td><td>destroy</td></tr>
+    <tr><td rowspan=2>{prefix}/{lookup}/{methodname}/[.format]</td><td>GET</td><td>@link decorated method</td><td rowspan=2>{basename}-{methodname}</td></tr>
+    <tr><td>POST</td><td>@action decorated method</td></tr>
+</table>
+
+# Custom Routers
+
+Implementing a custom router isn't something you'd need to do very often, but it can be useful if you have specfic requirements about how the your URLs for your API are strutured.  Doing so allows you to encapsulate the URL structure in a reusable way that ensures you don't have to write your URL patterns explicitly for each new view.
+
+The simplest way to implement a custom router is to subclass one of the existing router classes.  The `.routes` attribute is used to template the URL patterns that will be mapped to each viewset. 
+
+## Example
+
+The following example will only route to the `list` and `retrieve` actions, and unlike the routers included by REST framework, it does not use the trailing slash convention.
+
+    class ReadOnlyRouter(SimpleRouter):
+        """
+        A router for read-only APIs, which doesn't use trailing suffixes.
+        """
+        routes = [
+            (r'^{prefix}$', {'get': 'list'}, '{basename}-list'),
+            (r'^{prefix}/{lookup}$', {'get': 'retrieve'}, '{basename}-detail')
+        ]
+
+## Advanced custom routers
+
+If you want to provide totally custom behavior, you can override `BaseRouter` and override the `get_urls(self)` method.  The method should insect the registered viewsets and return a list of URL patterns.  The registered prefix, viewset and basename tuples may be inspected by accessing the `self.registry` attribute.  
+
+You may also want to override the `get_default_base_name(self, viewset)` method, or else always explicitly set the `base_name` argument when registering your viewsets with the router.

+## How hyperlinked views are determined
 
-## Specifying which fields should be read-only 
+There needs to be a way of determining which views should be used for hyperlinking to model instances.
 
-You may wish to specify multiple fields as read-only. Instead of adding each field explicitly with the `read_only=True` attribute, you may use the `read_only_fields` Meta option, like so:
+By default hyperlinks are expected to correspond to a view name that matches the style `'{model_name}-detail'`, and looks up the instance by a `pk` keyword argument.
 
-    class AccountSerializer(serializers.ModelSerializer):
+You can change the field that is used for object lookups by setting the `lookup_field` option.  The value of this option should correspond both with a kwarg in the URL conf, and with an field on the model.  For example:
+
+    class AccountSerializer(serializers.HyperlinkedModelSerializer):
         class Meta:
             model = Account
-            read_only_fields = ('created', 'modified')
+            fields = ('url', 'account_name', 'users', 'created')
+            lookup_field = 'slug'
+
+For more specfic requirements such as specifying a different lookup for each field, you'll want to set the fields on the serializer explicitly.  For example:
+
+    class AccountSerializer(serializers.HyperlinkedModelSerializer):
+        url = serializers.HyperlinkedIdentityField(
+            view_name='account_detail',
+            lookup_field='account_name'
+        )
+        users = serializers.HyperlinkedRelatedField(

+            lookup_field='username',
+            many=True,
+            read_only=True
+        )
+
+        class Meta:
+            model = Account
+            fields = ('url', 'account_name', 'users', 'created')
+
+---
+
+# Advanced serializer usage
+
+You can create customized subclasses of `ModelSerializer` or `HyperlinkedModelSerializer` that use a different set of default fields.
+
+Doing so should be considered advanced usage, and will only be needed if you have some particular serializer requirements that you often need to repeat.
 
 ## Customising the default fields
 
-You can create customized subclasses of `ModelSerializer` that use a different set of default fields for the representation, by overriding various `get_<field_type>_field` methods.
+The `field_mapping` attribute is a dictionary that maps model classes to serializer classes.  Overriding the attribute will let you set a different set of default serializer classes. 
 
-Each of these methods may either return a field or serializer instance, or `None`.
+For more advanced customization than simply changing the default serializer class you can override various `get_<field_type>_field` methods.  Doing so will allow you to customize the arguments that each serializer field is initialized with. Each of these methods may either return a field or serializer instance, or `None`.

+# ViewSets
+
+> After routing has determined which controller to use for a request, your controller is responsible for making sense of the request and producing the appropriate output.
+>
+> &mdash; [Ruby on Rails Documentation][cite]
+
+
+Django REST framework allows you to combine the logic for a set of related views in a single class, called a `ViewSet`.  In other frameworks you may also find conceptually similar implementations named something like 'Resources' or 'Controllers'.
+
+A `ViewSet` class is simply **a type of class-based View, that does not provide any method handlers** such as `.get()` or `.post()`, and instead provides actions such as `.list()` and `.create()`.
+
+The method handlers for a `ViewSet` are only bound to the corresponding actions at the point of finalizing the view, using the `.as_view()` method.
+
+Typically, rather than exlicitly registering the views in a viewset in the urlconf, you'll register the viewset with a router class, that automatically determines the urlconf for you.
+
+## Example
+
+Let's define a simple viewset that can be used to listing or retrieving all the users in the system.
+
+    class UserViewSet(viewsets.ViewSet):
+        """
+        A simple ViewSet that for listing or retrieving users.
+        """
+        def list(self, request):
+            queryset = User.objects.all()
+            serializer = UserSerializer(queryset, many=True)
+            return Response(serializer.data)
+            
+        def retrieve(self, request, pk=None):
+            queryset = User.objects.all()
+            user = get_object_or_404(queryset, pk=pk)
+            serializer = UserSerializer(user)
+            return Response(serializer.data)
+
+If we need to, we can bind this viewset into two seperate views, like so:
+
+    user_list = UserViewSet.as_view({'get': 'list'})
+    user_detail = UserViewSet.as_view({'get': 'retrieve'})
+
+Typically we wouldn't do this, but would instead register the viewset with a router, and allow the urlconf to be automatically generated.
+
+    router = DefaultRouter()
+    router.register(r'users', UserViewSet)
+    urlpatterns = router.urls
+
+Rather than writing your own viewsets, you'll often want to use the existing base classes that provide a default set of behavior.  For example:
+
+    class UserViewSet(viewsets.ModelViewSet):
+        """
+        A viewset for viewing and editing user instances.
+        """
+        serializer_class = UserSerializer
+        queryset = User.objects.all()
+
+There are two main advantages of using a `ViewSet` class over using a `View` class.
+
+* Repeated logic can be combined into a single class.  In the above example, we only need to specify the `queryset` once, and it'll be used across multiple views.
+* By using routers, we no longer need to deal with wiring up the URL conf ourselves.
+
+Both of these come with a trade-off.  Using regular views and URL confs is more explicit and gives you more control.  ViewSets are helpful if you want to get up and running quickly, or when you have a large API and you want to enforce a consistent URL configuration throughout.
+
+## Marking extra methods for routing
+
+The default routers included with REST framework will provide routes for a standard set of create/retrieve/update/destroy style operations, as shown below:
+
+    class UserViewSet(viewsets.VietSet):
+        """
+        Example empty viewset demonstrating the standard
+        actions that will be handled by a router class.
+        
+        If you're using format suffixes, make sure to also include
+        the `format=None` keyword argument for each action.
+        """
+
+        def list(self, request):
+            pass
+
+        def create(self, request):
+            pass
+
+        def retrieve(self, request, pk=None):
+            pass
+
+        def update(self, request, pk=None):
+            pass
+
+        def partial_update(self, request, pk=None):
+            pass
+
+        def destroy(self, request, pk=None):
+            pass
+
+If you have ad-hoc methods that you need to be routed to, you can mark them as requiring routing using the `@link` or `@action` decorators.  The `@link` decorator will route `GET` requests, and the `@action` decroator will route `POST` requests.
+
+For example:
+
+    from django.contrib.auth.models import User
+    from rest_framework import viewsets
+    from rest_framework.decorators import action
+    from myapp.serializers import UserSerializer
+
+    class UserViewSet(viewsets.ModelViewSet):
+        """
+        A viewset that provides the standard actions 
+        """
+        queryset = User.objects.all()
+        serializer_class = UserSerializer
+        
+        @action
+        def set_password(self, request, pk=None):
+            user = self.get_object()
+            serializer = PasswordSerializer(data=request.DATA)
+            if serializer.is_valid():
+                user.set_password(serializer.data['password'])
+                user.save()
+                return Response({'status': 'password set'})
+            else:
+                return Response(serializer.errors,
+                                status=status.HTTP_400_BAD_REQUEST)
+
+The `@action` and `@link` decorators can additionally take extra arguments that will be set for the routed view only.  For example...
+
+        @action(permission_classes=[IsAdminOrIsSelf])
+        def set_password(self, request, pk=None):
+           ...
+
+---
+
+# API Reference
+
+## ViewSet
+
+The `ViewSet` class inherits from `APIView`.  You can use any of the standard attributes such as `permission_classes`, `authentication_classes` in order to control the API policy on the viewset.
+
+The `ViewSet` class does not provide any implementations of actions.  In order to use a `ViewSet` class you'll override the class and define the action implementations explicitly.
+
+## ModelViewSet
+
+The `ModelViewSet` class inherits from `GenericAPIView` and includes implementations for various actions, by mixing in the behavior of the
+
+The actions provided by the `ModelViewSet` class are `.list()`, `.retrieve()`,  `.create()`, `.update()`, and `.destroy()`.
+
+#### Example
+
+Because `ModelViewSet` extends `GenericAPIView`, you'll normally need to provide at least the `queryset` and `serializer_class` attributes.  For example:
+
+    class AccountViewSet(viewsets.ModelViewSet):
+        """
+        A simple ViewSet for viewing and editing accounts.
+        """
+        queryset = Account.objects.all()
+        serializer_class = AccountSerializer
+        permission_classes = [IsAccountAdminOrReadOnly]
+
+Note that you can use any of the standard attributes or method overrides provided by `GenericAPIView`.  For example, to use a `ViewSet` that dynamically determines the queryset it should operate on, you might do something like this:
+
+    class AccountViewSet(viewsets.ModelViewSet):
+        """
+        A simple ViewSet for viewing and editing the accounts
+        associated with the user.
+        """
+        serializer_class = AccountSerializer
+        permission_classes = [IsAccountAdminOrReadOnly]
+
+        def get_queryset(self):
+            return request.user.accounts.all()
+
+Also note that although this class provides the complete set of create/list/retrieve/update/destroy actions by default, you can restrict the available operations by using the standard permission classes.
+
+## ReadOnlyModelViewSet
+
+The `ReadOnlyModelViewSet` class also inherits from `GenericAPIView`.  As with `ModelViewSet` it also includes implementations for various actions, but unlike `ModelViewSet` only provides the 'read-only' actions, `.list()` and `.retrieve()`.
+
+#### Example
+
+As with `ModelViewSet`, you'll normally need to provide at least the `queryset` and `serializer_class` attributes.  For example:
+
+    class AccountViewSet(viewsets.ReadOnlyModelViewSet):
+        """
+        A simple ViewSet for viewing accounts.
+        """
+        queryset = Account.objects.all()
+        serializer_class = AccountSerializer
+
+Again, as with `ModelViewSet`, you can use any of the standard attributes and method overrides available to `GenericAPIView`.
+
+# Custom ViewSet base classes 
+
+Any standard `View` class can be turned into a `ViewSet` class by mixing in `ViewSetMixin`.  You can use this to define your own base classes.
+
+## Example
+
+For example, we can create a base viewset class that provides `retrieve`, `update` and `list` operations:
+
+    class RetrieveUpdateListViewSet(mixins.RetrieveModelMixin,
+                                    mixins.UpdateModelMixin,
+                                    mixins.ListModelMixin,
+                                    viewsets.ViewSetMixin,
+                                    generics.GenericAPIView):
+        """
+        A viewset that provides `retrieve`, `update`, and `list` actions.
+        
+        To use it, override the class and set the `.queryset` and
+        `.serializer_class` attributes.
+        """
+        pass
+
+By creating your own base `ViewSet` classes, you can provide common behavior that can be reused in multiple views across your API.

+REST framework 2.3 makes it even quicker and easier to build your Web APIs.
+
+## ViewSets and Routers
+
+The 2.3 release introduces the [ViewSet][viewset] and [Router][router] classes.
+
+A viewset is simply a type of class based view that allows you to group multiple views into a single common class.
+
+Routers allow you to automatically determine the URLconf for your viewset classes.
+
+As an example of just how simple REST framework APIs can now be, here's an API written in a single `urls.py` module:
+
+    """
+    A REST framework API for viewing and editing users and groups.
+    """
+    from django.conf.urls.defaults import url, patterns, include
+    from django.contrib.auth.models import User, Group
+    from rest_framework import viewsets, routers
+
+
+    # ViewSets define the view behavior.
+    class UserViewSet(viewsets.ModelViewSet):
+        model = User
+
+    class GroupViewSet(viewsets.ModelViewSet):
+        model = Group
+
+    
+    # Routers provide an easy way of automatically determining the URL conf
+    router = routers.DefaultRouter()
+    router.register(r'users', views.UserViewSet)
+    router.register(r'groups', views.GroupViewSet)
+
+
+    # Wire up our API using automatic URL routing.
+    # Additionally, we include login URLs for the browseable API.
+    urlpatterns = patterns('',
+        url(r'^', include(router.urls)),
+        url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
+    )
+
+The best place to get started with ViewSets and Routers is to take a look at the [newest section in the tutorial][part-6], which demonstrates their usage.

+This release rationalises the API and implementation of the generic views, dropping the dependancy on Django's `SingleObjectMixin` and `MultipleObjectMixin` classes, removing a number of unneeded attributes, and generally making the implementation more obvious and easy to work with.
+
+This improvement is reflected in improved documentation for the `GenericAPIView` base class, and should make it easier to determine how to override methods on the base class if you need to write customized subclasses.
+
+## Easier Serializers
+
+REST framework lets you be totally explict regarding how you want to represent relationships, allowing you to choose between styles such as hyperlinking or primary key relationships.
+
+The ability to specify exactly how you want to represent relationships is powerful, but it also introduces complexity.  In order to keep things more simple, REST framework now allows you to include reverse relationships simply by including the field name in the `fields` metadata of the serializer class.
+
+For example, in REST framework 2.2, reverse relationships needed to be included explicitly on a serializer class.
+
+    class BlogSerializer(serializers.ModelSerializer):
+        comments = serializers.PrimaryKeyRelatedField(many=True)
+
+        class Meta:
+            model = Blog
+            fields = ('id', 'title', 'created', 'comments')
+
+As of 2.3, you can simply include the field name, and the appropriate serializer field will automatically be used for the relationship.
+
+    class BlogSerializer(serializers.ModelSerializer):
+        """
+        Don't need to specify the 'comments' field explicitly anymore.
+        """
+        class Meta:
+            model = Blog
+            fields = ('id', 'title', 'created', 'comments')
+
+Similarly, you can now easily include the primary key in hyperlinked relationships, simply by adding the field name to the metadata.
+
+    class BlogSerializer(serializers.HyperlinkedModelSerializer):
+        """
+        This is a hyperlinked serializer, which default to using
+        a field named 'url' as the primary identifier.
+        Note that we can now easily also add in the 'id' field.
+        """
+        class Meta:
+            model = Blog
+            fields = ('url', 'id', 'title', 'created', 'comments')
+
+## More flexible filtering
+
+The `FILTER_BACKEND` setting has moved to pending deprecation, in favor of a `DEFAULT_FILTER_BACKENDS` setting that takes a *list* of filter backend classes, instead of a single filter backend class.
+
+The generic view `filter_backend` attribute has also been moved to pending deprecation in favor of a `filter_backends` setting.
+
+Being able to specify multiple filters will allow for more flexible, powerful behavior.  New filter classes to handle searching and ordering of results are planned to be released shortly.
+
+---
+
+# API Changes
+
+## Simplified generic view classes
+
+The functionality provided by `SingleObjectAPIView` and `MultipleObjectAPIView` base classes has now been moved into the base class `GenericAPIView`.  The implementation of this base class is simple enough that providing subclasses for the base classes of detail and list views is somewhat unnecessary.
+
+Additionally the base generic view no longer inherits from Django's `SingleObjectMixin` or `MultipleObjectMixin` classes, simplifying the implementation, and meaning you don't need to cross-reference across to Django's codebase.
+
+Using the `SingleObjectAPIView` and `MultipleObjectAPIView` base classes continues to be supported, but will raise a `PendingDeprecationWarning`.  You should instead simply use `GenericAPIView` as the base for any generic view subclasses.
+
+### Removed attributes
+
+The following attributes and methods, were previously present as part of Django's generic view implementations, but were unneeded and unusedand have now been entirely removed.
+
+* context_object_name
+* get_context_data()
+* get_context_object_name()
+
+The following attributes and methods, which were previously present as part of Django's generic view implementations have also been entirely removed.
+
+* paginator_class
+* get_paginator()
+* get_allow_empty()
+* get_slug_field()
+
+There may be cases when removing these bits of API might mean you need to write a little more code if your view has highly customized behavior, but generally we believe that providing a coarser-grained API will make the views easier to work with, and is the right trade-off to make for the vast majority of cases.
+
+Note that the listed attributes and methods have never been a documented part of the REST framework API, and as such are not covered by the deprecation policy.
+
+### Simplified methods
+
+The `get_object` and `get_paginate_by` methods no longer take an optional queryset argument.  This makes overridden these methods more obvious, and a little more simple.
+
+Using an optional queryset with these methods continues to be supported, but will raise a `PendingDeprecationWarning`.
+
+The `paginate_queryset` method no longer takes a `page_size` argument, or returns a four-tuple of pagination information.  Instead it simply takes a queryset argument, and either returns a `page` object with an appropraite page size, or returns `None`, if pagination is not configured for the view.
+
+Using the `page_size` argument is still supported and will trigger the old-style return type, but will raise a `PendingDeprecationWarning`.
+
+### Deprecated attributes
+
+The following attributes are used to control queryset lookup, and have all been moved into a pending deprecation state.
+
+* pk_url_kwarg = 'pk'
+* slug_url_kwarg = 'slug'
+* slug_field = 'slug'
+
+Their usage is replaced with a single attribute:
+
+* lookup_field = 'pk'
+
+This attribute is used both as the regex keyword argument in the URL conf, and as the model field to filter against when looking up a model instance.  To use non-pk based lookup, simply set the `lookup_field` argument to an alternative field, and ensure that the keyword argument in the url conf matches the field name.
+
+For example, a view with 'username' based lookup might look like this:
+
+    class UserDetail(generics.RetrieveAPIView):
+        lookup_field = 'username'
+        queryset = User.objects.all()
+        serializer_class = UserSerializer
+
+And would have the following entry in the urlconf:
+
+     url(r'^users/(?P<username>\w+)/$', UserDetail.as_view()),
+
+Usage of the old-style attributes continues to be supported, but will raise a `PendingDeprecationWarning`.
+
+The `allow_empty` attribute is also deprecated.  To use `allow_empty=False` style behavior you should explicitly override `get_queryset` and raise an `Http404` on empty querysets.
+
+For example:
+
+    class DisallowEmptyQuerysetMixin(object):
+        def get_queryset(self):
+            queryset = super(DisallowEmptyQuerysetMixin, self).get_queryset()
+            if not queryset.exists():
+                raise Http404
+            return queryset
+
+In our opinion removing lesser-used attributes like `allow_empty` helps us move towards simpler generic view implementations, making them more obvious to use and override, and re-inforcing the preferred style of developers writing their own base classes and mixins for custom behavior rather than relying on the configurability of the generic views.
+
+## Simpler URL lookups
+
+The `HyperlinkedRelatedField` class now takes a single optional `lookup_field` argument, that replaces the `pk_url_kwarg`, `slug_url_kwarg`, and `slug_field` arguments.
+
+For example, you might have a field that references it's relationship by a hyperlink based on a slug field:
+
+        account = HyperlinkedRelatedField(read_only=True,
+                                          lookup_field='slug',
+                                          view_name='account-detail')
+
+Usage of the old-style attributes continues to be supported, but will raise a `PendingDeprecationWarning`.
+
+## DecimalField
+
+2.3 introduces a `DecimalField` serializer field, which returns `Decimal` instances.
+
+For most cases APIs using model fields will behave as previously, however if you are using a custom renderer, not provided by REST framework, then you may now need to add support for rendering `Decimal` instances to your renderer implmentation.
+
+## ModelSerializers and reverse relationships 
+
+The support for adding reverse relationships to the `fields` option on a `ModelSerializer` class means that the `get_related_field` and `get_nested_field` method signatures have now changed.
+
+In the unlikely event that you're providing a custom serializer class, and implementing these methods you should note the new call signature for both methods is now `(self, model_field, related_model, to_many)`.  For revese relationships `model_field` will be `None`.
+
+The old-style signature will continue to function but will raise a `PendingDeprecationWarning`. 
+
+## View names and descriptions
+
+The mechanics of how the names and descriptions used in the browseable API are generated has been modified and cleaned up somewhat.
+
+If you've been customizing this behavior, for example perhaps to use `rst` markup for the browseable API, then you'll need to take a look at the implementation to see what updates you need to make.
+
+Note that the relevant methods have always been private APIs, and the docstrings called them out as intended to be deprecated. 
+
+---
+
+# Other notes
+
+## More explicit style
+
+The usage of `model` attribute in generic Views is still supported, but it's usage is generally being discouraged throughout the documentation, in favour of the setting the more explict `queryset` and `serializer_class` attributes.
+
+For example, the following is now the recommended style for using generic views:
+
+    class AccountListView(generics.RetrieveAPIView):
+        queryset = MyModel.objects.all()
+        serializer_class = MyModelSerializer
+
+Using an explict `queryset` and `serializer_class` attributes makes the functioning of the view more clear than using the shortcut `model` attribute.
+
+It also makes the usage of the `get_queryset()` or `get_serializer_class()` methods more obvious.
+
+    class AccountListView(generics.RetrieveAPIView):
+        serializer_class = MyModelSerializer
+
+        def get_queryset(self):
+            """
+            Determine the queryset dynamically, depending on the
+            user making the request.
+
+            Note that overriding this method follows on more obviously now
+            that an explicit `queryset` attribute is the usual view style.
+            """
+            return self.user.accounts
+
+## Django 1.3 support
+
+The 2.3.x release series will be the last series to provide compatiblity with Django 1.3.
+
+## Version 2.2 API changes
+
+All API changes in 2.2 that previously raised `PendingDeprecationWarning` will now raise a `DeprecationWarning`, which is loud by default.
+
+## What comes next?
+
+* Support for read-write nested serializers is almost complete, and due to be released in the next few weeks.
+* Extra filter backends for searching and ordering of results are planned to be added shortly.
+
+The next few months should see a renewed focus on addressing outstanding tickets.  The 2.4 release is currently planned for around August-September.

-# 2.0 Migration Guide
-
-> Move fast and break things
->
-> &mdash; Mark Zuckerberg, [the Hacker Way][cite].
-
-REST framework 2.0 introduces a radical redesign of the core components, and a large number of backwards breaking changes.
-
-### Serialization redesign.
-
-REST framework's serialization and deserialization previously used a slightly odd combination of serializers for output, and Django Forms and Model Forms for input.  The serialization core has been completely redesigned based on work that was originally intended for Django core.
-
-2.0's form-like serializers comprehensively address those issues, and are a much more flexible and clean solution to the problems around accepting both form-based and non-form based inputs.
-
-### Generic views improved.
-
-When REST framework 0.1 was released the current Django version was 1.2.  REST framework included a backport of the Django 1.3's upcoming `View` class, but it didn't take full advantage of the generic view implementations.
-
-As of 2.0 the generic views in REST framework tie in much more cleanly and obviously with Django's existing codebase, and the mixin architecture is radically simplified.
-
-### Cleaner request-response cycle.
-
-REST framework 2.0's request-response cycle is now much less complex.
-
-* Responses inherit from `SimpleTemplateResponse`, allowing rendering to be delegated to the response, not handled by the view.
-* Requests extend the regular `HttpRequest`, allowing authentication and parsing to be delegated to the request, not handled by the view.
-
-### Renamed attributes & classes.
-
-Various attributes and classes have been renamed in order to fit in better with Django's conventions.
-
-## Example: Blog Posts API
-
-Let's take a look at an example from the REST framework 0.4 documentation...
-
-    from djangorestframework.resources import ModelResource
-    from djangorestframework.reverse import reverse
-    from blogpost.models import BlogPost, Comment
-
-
-    class BlogPostResource(ModelResource):
-        """
-        A Blog Post has a *title* and *content*, and can be associated
-        with zero or more comments.
-        """
-        model = BlogPost
-        fields = ('created', 'title', 'slug', 'content', 'url', 'comments')
-        ordering = ('-created',)
-
-        def url(self, instance):
-            return reverse('blog-post',
-                            kwargs={'key': instance.key},
-                            request=self.request)
-
-        def comments(self, instance):
-            return reverse('comments',
-                           kwargs={'blogpost': instance.key},
-                           request=self.request)
-
-
-    class CommentResource(ModelResource):
-        """
-        A Comment is associated with a given Blog Post and has a
-        *username* and *comment*, and optionally a *rating*.
-        """
-        model = Comment
-        fields = ('username', 'comment', 'created', 'rating', 'url', 'blogpost')
-        ordering = ('-created',)
-
-        def blogpost(self, instance):
-            return reverse('blog-post',
-                           kwargs={'key': instance.blogpost.key},
-                           request=self.request)
-
-There's a bit of a mix of concerns going on there.  We've got some information about how the data should be serialized, such as the `fields` attribute, and some information about how it should be retrieved from the database - the `ordering` attribute.
-
-Let's start to re-write this for REST framework 2.0.
-
-    from rest_framework import serializers
-
-    class BlogPostSerializer(serializers.HyperlinkedModelSerializer):
-        model = BlogPost
-        fields = ('created', 'title', 'slug', 'content', 'url', 'comments')
-
-    class CommentSerializer(serializers.HyperlinkedModelSerializer):
-        model = Comment
-        fields = ('username', 'comment', 'created', 'rating', 'url', 'blogpost')

+# Tutorial 6 - ViewSets & Routers
+
+REST framework includes an abstraction for dealing with `ViewSets`, that allows the developer to concentrate on modeling the state and interactions of the API, and leave the URL construction to be handled automatically, based on common conventions.
+
+`ViewSet` classes are almost the same thing as `View` classes, except that they provide operations such as `read`, or `update`, and not method handlers such as `get` or `put`.
+
+A `ViewSet` class is only bound to a set of method handlers at the last moment, when it is instantiated into a set of views, typically by using a `Router` class which handles the complexities of defining the URL conf for you.
+
+## Refactoring to use ViewSets
+
+Let's take our current set of views, and refactor them into view sets.
+
+First of all let's refactor our `UserListView` and `UserDetailView` views into a single `UserViewSet`.  We can remove the two views, and replace then with a single class:
+
+    class UserViewSet(viewsets.ReadOnlyModelViewSet):
+        """
+        This viewset automatically provides `list` and `detail` actions.
+        """
+        queryset = User.objects.all()
+        serializer_class = UserSerializer
+
+Here we've used `ReadOnlyModelViewSet` class to automatically provide the default 'read-only' operations.  We're still setting the `queryset` and `serializer_class` attributes exactly as we did when we were using regular views, but we no longer need to provide the same information to two separate classes.
+
+Next we're going to replace the `SnippetList`, `SnippetDetail` and `SnippetHighlight` view classes.  We can remove the three views, and again replace them with a single class.
+
+    from rest_framework import viewsets
+    from rest_framework.decorators import link
+
+    class SnippetViewSet(viewsets.ModelViewSet):
+        """
+        This viewset automatically provides `list`, `create`, `retrieve`,
+        `update` and `destroy` actions.
+        
+        Additionally we also provide an extra `highlight` action. 
+        """
+        queryset = Snippet.objects.all()
+        serializer_class = SnippetSerializer
+        permission_classes = (permissions.IsAuthenticatedOrReadOnly,
+                              IsOwnerOrReadOnly,)
+
+        @link(renderer_classes=[renderers.StaticHTMLRenderer])
+        def highlight(self, request, *args, **kwargs):
+            snippet = self.get_object()
+            return Response(snippet.highlighted)
+
+        def pre_save(self, obj):
+            obj.owner = self.request.user
+
+This time we've used the `ModelViewSet` class in order to get the complete set of default read and write operations.
+
+Notice that we've also used the `@link` decorator to create a custom action, named `highlight`.  This decorator can be used to add any custom endpoints that don't fit into the standard `create`/`update`/`delete` style.
+
+Custom actions which use the `@link` decorator will respond to `GET` requests.  We could have instead used the `@action` decorator if we wanted an action that responded to `POST` requests.
+
+## Binding ViewSets to URLs explicitly
+
+The handler methods only get bound to the actions when we define the URLConf.
+To see what's going on under the hood let's first explicitly create a set of views from our ViewSets.
+
+In the `urls.py` file we bind our `ViewSet` classes into a set of concrete views.
+
+    from snippets.resources import SnippetResource, UserResource
+
+    snippet_list = SnippetViewSet.as_view({
+        'get': 'list',
+        'post': 'create'
+    })
+    snippet_detail = SnippetViewSet.as_view({
+        'get': 'retrieve',
+        'put': 'update',
+        'patch': 'partial_update',
+        'delete': 'destroy'
+    })
+    snippet_highlight = SnippetViewSet.as_view({
+        'get': 'highlight'
+    })
+    user_list = UserViewSet.as_view({
+        'get': 'list'
+    })
+    user_detail = UserViewSet.as_view({
+        'get': 'retrieve'
+    })
+
+Notice how we're creating multiple views from each `ViewSet` class, by binding the http methods to the required action for each view.
+
+Now that we've bound our resources into concrete views, that we can register the views with the URL conf as usual.
+
+    urlpatterns = format_suffix_patterns(patterns('snippets.views',
+        url(r'^$', 'api_root'),
+        url(r'^snippets/$', snippet_list, name='snippet-list'),
+        url(r'^snippets/(?P<pk>[0-9]+)/$', snippet_detail, name='snippet-detail'),
+        url(r'^snippets/(?P<pk>[0-9]+)/highlight/$', snippet_highlight, name='snippet-highlight'),
+        url(r'^users/$', user_list, name='user-list'),
+        url(r'^users/(?P<pk>[0-9]+)/$', user_detail, name='user-detail')
+    ))
+
+## Using Routers
+
+Because we're using `ViewSet` classes rather than `View` classes, we actually don't need to design the URL conf ourselves.  The conventions for wiring up resources into views and urls can be handled automatically, using a `Router` class.  All we need to do is register the appropriate view sets with a router, and let it do the rest.
+
+Here's our re-wired `urls.py` file.
+
+    from snippets import views
+    from rest_framework.routers import DefaultRouter
+
+    # Create a router and register our viewsets with it.
+    router = DefaultRouter()
+    router.register(r'snippets', views.SnippetViewSet)
+    router.register(r'users', views.UserViewSet)
+    
+    # The API URLs are now determined automatically by the router.
+    # Additionally, we include the login URLs for the browseable API.
+    urlpatterns = patterns('',
+        url(r'^', include(router.urls)),
+        url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
+    )
+
+Registering the viewsets with the router is similar to providing a urlpattern.  We include two arguments - the URL prefix for the views, and the viewset itself.
+
+The `DefaultRouter` class we're using also automatically creates the API root view for us, so we can now delete the `api_root` method from our `views` module.
+
+## Trade-offs between views vs viewsets.
+
+Using viewsets can be a really useful abstraction.  It helps ensure that URL conventions will be consistent across your API, minimizes the amount of code you need to write, and allows you to concentrate on the interactions and representations your API provides rather than the specifics of the URL conf.
+
+That doesn't mean it's always the right approach to take.  There's a similar set of trade-offs to consider as when using class-based views instead of function based views.  Using viewsets is less explicit than building your views individually.
+
+## Reviewing our work
+
+With an incredibly small amount of code, we've now got a complete pastebin Web API, which is fully web browseable, and comes complete with authentication, per-object permissions, and multiple renderer formats.
+
+We've walked through each step of the design process, and seen how if we need to customize anything we can gradually work our way down to simply using regular Django views.
+
+You can review the final [tutorial code][repo] on GitHub, or try out a live example in [the sandbox][sandbox].

 Notice that we're using hyperlinked relations in this case, with `HyperlinkedModelSerializer`.  You can also use primary key and various other relationships, but hyperlinking is good RESTful design.
 
-We've also overridden the `permission` field on the `GroupSerializer`.  In this case we don't want to use a hyperlinked representation, but instead use the list of permission codenames associated with the group, so we've used a `ManySlugRelatedField`, using the `codename` field for the representation.

 ## Views
 
 Right, we'd better write some views then.  Open `quickstart/views.py` and get typing.

     from quickstart.serializers import UserSerializer, GroupSerializer
     
     
-    @api_view(['GET'])
-    def api_root(request, format=None):
-        """
-        The entry endpoint of our API.
-        """
-        return Response({
-            'users': reverse('user-list', request=request),
-            'groups': reverse('group-list', request=request),
-        })
-    
-    
-    class UserList(generics.ListCreateAPIView):

-        API endpoint that represents a list of users.
-        """
-        model = User
-        serializer_class = UserSerializer
-    
-    
-    class UserDetail(generics.RetrieveUpdateDestroyAPIView):
+    class UserViewSet(viewsets.ModelViewSet):
         """
-        API endpoint that represents a single user.
+        API endpoint that allows users to be viewed or edited.
         """
-        model = User
+        queryset = User.objects.all()
         serializer_class = UserSerializer
     
     
-    class GroupList(generics.ListCreateAPIView):
+    class GroupViewSet(viewsets.ModelViewSet):
         """
-        API endpoint that represents a list of groups.
+        API endpoint that allows groups to be viewed or edited.
         """
-        model = Group
-        serializer_class = GroupSerializer
-    
-    
-    class GroupDetail(generics.RetrieveUpdateDestroyAPIView):

-        """
-        model = Group
+        queryset = Group.objects.all()
         serializer_class = GroupSerializer
 
-Let's take a moment to look at what we've done here before we move on.  We have one function-based view representing the root of the API, and four class-based views which map to our database models, and specify which serializers should be used for representing that data.  Pretty simple stuff.
+Rather that write multiple views we're grouping together all the common behavior into classes called `ViewSets`.
+
+We can easily break these down into individual views if we need to, but using viewsets keeps the view logic nicely organized as well as being very concise.

-There's a few things worth noting here.
-
-Firstly the names `user-detail` and `group-detail` are important.  We're using the default hyperlinked relationships without explicitly specifying the view names, so we need to use names of the style `{modelname}-detail` to represent the model instance views.
+Because we're using viewsets instead of views, we can automatically generate the URL conf for our API, by simply registering the viewsets with a router class.
 
-Secondly, we're modifying the urlpatterns using `format_suffix_patterns`, to append optional `.json` style suffixes to our URLs.
+Again, if we need more control over the API URLs we can simply drop down to using regular class based views, and writing the URL conf explicitly.
