Nested resources for the Django Rest Framework

**This is a work in progress. It "works for me" at,
but I cannot warranty that it fully "works everywhere" yet. Join us on Gitter (below) if you need some help.**

This package provides routers and fields to create nested resources in the [Django Rest Framework](

Nested resources are needed for full REST URL structure, if one resource lives inside another.

The following example is about Domains and DNS Nameservers.
There are many domains, and each domain has many nameservers. The "nameserver" resource does not
exist without a domain, so you need it "nested" inside the domain.


You can install this library using pip:

```pip install drf-nested-routers```


The desired URL signatures are:
\domain\ <- Domains list
\domain\{pk}\ <- One domain, from {pk}
\domain\{domain_pk}\nameservers\ <- Nameservers of domain from {domain_pk}
\domain\{domain_pk}\nameservers\{pk} <- Specific nameserver from {pk}, of domain from {domain_pk}

How to do it (example):
from rest_framework_nested import routers
from views import DomainViewSet, NameserverViewSet

router = routers.SimpleRouter()
router.register(r'domains', DomainViewSet)

domains_router = routers.NestedSimpleRouter(router, r'domains', lookup='domain')
domains_router.register(r'nameservers', NameserverViewSet, base_name='domain-nameservers')
# 'base_name' is optional. Needed only if the same viewset is registered more than once
# Official DRF docs on this option:

urlpatterns = patterns('',
url(r'^', include(router.urls)),
url(r'^', include(domains_router.urls)),
class NameserverViewSet(viewsets.ViewSet):
def list(self, request, domain_pk=None):
nameservers = self.queryset.filter(domain=domain_pk)
return Response([...])

def retrieve(self, request, pk=None, domain_pk=None):
nameservers = self.queryset.get(pk=pk, domain=domain_pk)
return Response(

(optional) If you need hyperlinks for nested relations, you need a custom serializer.
# (needed only if you want hyperlinks for nested relations on API)
from rest_framework_nested.relations import NestedHyperlinkedRelatedField

class DomainSerializer(HyperlinkedModelSerializer):
class Meta:
model = Domain

nameservers = HyperlinkedIdentityField(

## OR ##

nameservers = NestedHyperlinkedRelatedField(
read_only=True, # Or add a queryset
parent_lookup_url_kwargs={'domain_pk': 'domain__pk'}

(optional) If you want a little bit more control over the fields displayed for the nested relations while looking at the parent, you need a custom serializer using NestedHyperlinkedModelSerializer.
from rest_framework.serializers import HyperlinkedModelSerializer
from rest_framework_nested.serializers import NestedHyperlinkedModelSerializer

class NameserverSerializers(HyperlinkedModelSerializer):
class Meta:
model = Nameserver
fields = (...)

class DomainNameserverSerializers(NestedHyperlinkedModelSerializer):
parent_lookup_kwargs = {
'domain_pk': 'domain__pk',
class Meta:
model = Nameserver
fields = ('url', ...)

class DomainSerializer(HyperlinkedModelSerializer):
class Meta:
model = Domain
fields = (..., 'nameservers')

nameservers = DomainNameserverSerializers(many=True, read_only=True)

Example of nested router 3 levels deep. You can use this same logic to nest routers as deep as you need. This example accomplishes the below URL patterns.

router = DefaultRouter()
router.register(r'clients', ClientViewSet, base_name='clients')

client_router = routers.NestedSimpleRouter(router, r'clients', lookup='client')
client_router.register(r'maildrops', MailDropViewSet, base_name='maildrops')

maildrops_router = routers.NestedSimpleRouter(client_router, r'maildrops', lookup='maildrop')
maildrops_router.register(r'recipients', MailRecipientViewSet, base_name='recipients')

urlpatterns = patterns (
url(r'^', include(router.urls)),
url(r'^', include(client_router.urls)),
url(r'^', include(maildrops_router.urls)),

class ClientViewSet(viewsets.ViewSet):
serializer_class = ClientSerializer

def list(self, request,):
queryset = Client.objects.filter()
serializer = ClientSerializer(queryset, many=True)
return Response(

def retrieve(self, request, pk=None):
queryset = Client.objects.filter()
client = get_object_or_404(queryset, pk=pk)
serializer = ClientSerializer(client)
return Response(

class MailDropViewSet(viewsets.ViewSet):
serializer_class = MailDropSerializer

def list(self, request, client_pk=None):
queryset = MailDrop.objects.filter(client=client_pk)
serializer = MailDropSerializer(queryset, many=True)
return Response(

def retrieve(self, request, pk=None, client_pk=None):
queryset = MailDrop.objects.filter(pk=pk, client=client_pk)
maildrop = get_object_or_404(queryset, pk=pk)
serializer = MailDropSerializer(maildrop)
return Response(

class MailRecipientViewSet(viewsets.ViewSet):
serializer_class = MailRecipientSerializer

def list(self, request, client_pk=None, maildrop_pk=None):
queryset = MailRecipient.objects.filter(mail_drop__client=client_pk, mail_drop=maildrop_pk)
serializer = MailRecipientSerializer(queryset, many=True)
return Response(

def retrieve(self, request, pk=None, client_pk=None, maildrop_pk=None):
queryset = MailRecipient.objects.filter(pk=pk, mail_drop=maildrop_pk, mail_drop__client=client_pk)
maildrop = get_object_or_404(queryset, pk=pk)
serializer = MailRecipientSerializer(maildrop)
return Response(

In order to get started with testing, you will need to install [tox](
Once installed, you can then run one environment locally, to speed up your development cycle:

$ tox -e py27-django1.8-drf3.0

Once you submit a pull request, your changes will be run against many environments with Travis.
