# drf-nested-routers

[![Join the chat at https://gitter.im/alanjds/drf-nested-routers](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/alanjds/drf-nested-routers?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
[![Build Status](https://github.com/alanjds/drf-nested-routers/workflows/CI/badge.svg)](https://github.com/alanjds/drf-nested-routers/actions?query=workflow%3ACI+branch%3Amaster)

This package provides routers and fields to create nested resources in the [Django Rest Framework](http://django-rest-framework.org/)

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.


## Requirements & Compatibility

-  Python (3.6, 3.7, 3.8, 3.9)
-  Django (2.2, 3.0, 3.1)
-  Django REST Framework (3.11)

It may work with lower versions, but since the release **0.92.1** is no more
tested on CI for Pythons 2.7 to 3.5, Django 1.11 to 2.1 or DRF 3.6 to 3.10.


## Installation

You can install this library using pip:

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

It is not needed to add this library in your Django project's `settings.py` file, as it does not contain any app, signal or model.

## Quickstart

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):
```python
# urls.py
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, basename='domain-nameservers')
# 'basename' is optional. Needed only if the same viewset is registered more than once
# Official DRF docs on this option: http://www.django-rest-framework.org/api-guide/routers/

urlpatterns = patterns('',
    url(r'^', include(router.urls)),
    url(r'^', include(domains_router.urls)),
)
```

```python
# views.py

## For Django' ORM-based resources ##

class NameserverViewSet(viewsets.ModelViewSet):
    def get_queryset(self):
        return Nameserver.objects.filter(domain=self.kwargs['domain_pk'])

## OR: non-ORM resources ##

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(serializer.data)
```

## Advanced

### Hyperlinks for Nested resources

**(optional)** If you need hyperlinks for nested relations, you need a custom serializer.

There you will inform how to access the *parent* of the instance being serialized when
building the *children* URL.

In the following example, an instance of Nameserver on `/domain/{domain_pk}/nameservers/{pk}`
is being informed that the *parent* Domain should be looked up using the `domain_pk` kwarg
from the URL:
```python
# serializers.py
# (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(
        view_name='domain-nameservers-list',
        lookup_url_kwarg='domain_pk'
                        # ^-- Nameserver queryset will .get(domain_pk=domain_pk)
                        #     being this value from URL kwargs
    )

	## OR ##

    nameservers = NestedHyperlinkedRelatedField(
        many=True,
        read_only=True,   # Or add a queryset
        view_name='domain-nameservers-detail',
        parent_lookup_kwargs={'domain_pk': 'domain__pk'}
                            # ^-- Nameserver queryset will .filter(domain__pk=domain_pk)
                            #     being domain_pk (ONE underscore) value from URL kwargs
    )
```

**(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.
```python
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)
```

### Infinite-depth Nesting

Example of nested router 3 levels deep.
You can use this same logic to nest routers as deep as you need.
This example ahead accomplishes the below URL patterns.
```
/clients/
/clients/{pk}/
/clients/{client_pk}/maildrops/
/clients/{client_pk}/maildrops/{maildrop_pk}/
/clients/{client_pk}/maildrops/{maildrop_pk}/recipients/
/clients/{client_pk}/maildrops/{maildrop_pk}/recipients/{pk}/
```

```python
# urls.py
router = DefaultRouter()
router.register(r'clients', ClientViewSet, basename='clients')
## generates:
# /clients/
# /clients/{pk}/

client_router = routers.NestedSimpleRouter(router, r'clients', lookup='client')
client_router.register(r'maildrops', MailDropViewSet, basename='maildrops')
## generates:
# /clients/{client_pk}/maildrops/
# /clients/{client_pk}/maildrops/{maildrop_pk}/

maildrops_router = routers.NestedSimpleRouter(client_router, r'maildrops', lookup='maildrop')
maildrops_router.register(r'recipients', MailRecipientViewSet, basename='recipients')
## generates:
# /clients/{client_pk}/maildrops/{maildrop_pk}/recipients/
# /clients/{client_pk}/maildrops/{maildrop_pk}/recipients/{pk}/

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

```python
# views.py
class ClientViewSet(viewsets.ViewSet):
    serializer_class = ClientSerializer

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

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


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(serializer.data)

    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(serializer.data)


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(serializer.data)

    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(serializer.data)
```

```python
# serializers.py
class ClientSerializer(HyperlinkedModelSerializer):
    class Meta:
        model = Client
        fields = (...)


class MailDropSerializer(NestedHyperlinkedModelSerializer):
    parent_lookup_kwargs = {
        'client_pk': 'client__pk',
    }
    class Meta:
        model = MailDrop
        fields = (...)


class MailRecipientSerializer(NestedHyperlinkedModelSerializer):
    parent_lookup_kwargs = {
        'maildrop_pk': 'mail_drop__pk',
        'client_pk': 'mail_drop__client__pk',
    }
    class Meta:
        model = MailRecipient
        fields = (...)
```

## Testing

In order to get started with testing, you will need to install [tox](https://tox.readthedocs.io/en/latest/).
Once installed, you can then run one environment locally, to speed up your development cycle:

```
$ tox -e py39-django3.1-drf3.11
```

Once you submit a pull request, your changes will be run against many environments with GitHub Actions named CI.

## OR: non-ORM resources ##

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(serializer.data)
```

## Advanced

### Hyperlinks for Nested resources

**(optional)** If you need hyperlinks for nested relations, you need a custom serializer.

There you will inform how to access the *parent* of the instance being serialized when
building the *children* URL.

In the following example, an instance of Nameserver on `/domain/{domain_pk}/nameservers/{pk}`
is being informed that the *parent* Domain should be looked up using the `domain_pk` kwarg
from the URL:
```python
# serializers.py
# (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(
        view_name='domain-nameservers-list',
        lookup_url_kwarg='domain_pk'
                        # ^-- Nameserver queryset will .get(domain_pk=domain_pk)
                        #     being this value from URL kwargs
    )

	## OR ##

    nameservers = NestedHyperlinkedRelatedField(
        many=True,
        read_only=True,   # Or add a queryset
        view_name='domain-nameservers-detail',
        parent_lookup_kwargs={'domain_pk': 'domain__pk'}
                            # ^-- Nameserver queryset will .filter(domain__pk=domain_pk)
                            #     being domain_pk (ONE underscore) value from URL kwargs
    )
```

**(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.
```python
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)
```

### Infinite-depth Nesting

Example of nested router 3 levels deep.
You can use this same logic to nest routers as deep as you need.
This example ahead accomplishes the below URL patterns.
```
/clients/
/clients/{pk}/
/clients/{client_pk}/maildrops/
/clients/{client_pk}/maildrops/{maildrop_pk}/
/clients/{client_pk}/maildrops/{maildrop_pk}/recipients/
/clients/{client_pk}/maildrops/{maildrop_pk}/recipients/{pk}/
```

```python
# urls.py
router = DefaultRouter()
router.register(r'clients', ClientViewSet, basename='clients')
## generates:
# /clients/
# /clients/{pk}/

client_router = routers.NestedSimpleRouter(router, r'clients', lookup='client')
client_router.register(r'maildrops', MailDropViewSet, basename='maildrops')
## generates:
# /clients/{client_pk}/maildrops/
# /clients/{client_pk}/maildrops/{maildrop_pk}/

maildrops_router = routers.NestedSimpleRouter(client_router, r'maildrops', lookup='maildrop')
maildrops_router.register(r'recipients', MailRecipientViewSet, basename='recipients')
## generates:
# /clients/{client_pk}/maildrops/{maildrop_pk}/recipients/
# /clients/{client_pk}/maildrops/{maildrop_pk}/recipients/{pk}/

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

```python
# views.py
class ClientViewSet(viewsets.ViewSet):
    serializer_class = ClientSerializer

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

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


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(serializer.data)

    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(serializer.data)


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(serializer.data)

    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(serializer.data)
```

```python
# serializers.py
class ClientSerializer(HyperlinkedModelSerializer):
    class Meta:
        model = Client
        fields = (...)


class MailDropSerializer(NestedHyperlinkedModelSerializer):
    parent_lookup_kwargs = {
        'client_pk': 'client__pk',
    }
    class Meta:
        model = MailDrop
        fields = (...)


class MailRecipientSerializer(NestedHyperlinkedModelSerializer):
    parent_lookup_kwargs = {
        'maildrop_pk': 'mail_drop__pk',
        'client_pk': 'mail_drop__client__pk',
    }
    class Meta:
        model = MailRecipient
        fields = (...)
```

## Testing

In order to get started with testing, you will need to install [tox](https://tox.readthedocs.io/en/latest/).
Once installed, you can then run one environment locally, to speed up your development cycle:

```
$ tox -e py39-django3.1-drf3.11
```

Once you submit a pull request, your changes will be run against many environments with GitHub Actions named CI.
