# drf-nested-resources
This is a django rest framework extension to allow developers to create nested
resources.
## How to use
### Configuration of nested resources
For this example we are going to create a simple API with the following
endpoints:
/developers/
/developers/<id>
/developers/<id>/languages/
/developers/<id>/languages/<id>
First we start with the following Django models:
```python
from django.db.models import CASCADE
from django.db.models.base import Model
from django.db.models.fields import CharField
from django.db.models.fields.related import ForeignKey
class Developer(Model):
name = CharField(max_length=20)
class ProgrammingLanguage(Model):
name = CharField(max_length=20)
author = ForeignKey(
Developer,
related_name='programming_languages',
on_delete=CASCADE,
)
```
We will have the two viewsets for both the `developers` and `languages` resource
collections.
```python
from rest_framework.viewsets import ModelViewSet
from drf_nested_resources.fields import HyperlinkedNestedModelSerializer
class _DeveloperSerializer(HyperlinkedNestedModelSerializer):
class Meta(object):
model = Developer
fields = ('url', 'name', 'programming_languages')
class DeveloperViewSet(ModelViewSet):
queryset = Developer.objects.all()
serializer_class = _DeveloperSerializer
class _ProgrammingLanguageSerializer(HyperlinkedNestedModelSerializer):
class Meta(object):
model = ProgrammingLanguage
fields = ('url', 'name', 'author')
class ProgrammingLanguageViewSet(ModelViewSet):
queryset = ProgrammingLanguage.objects.all()
serializer_class = _ProgrammingLanguageSerializer
```
The related fields in the ViewSets `author` and `programming_languages` should
follow the model representation so that `author` will give us a url for the
developer who wrote the ProgrammingLanguage and the `programming_languages`
should give us a list of urls for the ProgrammingLanguages that the Developer
wrote.
This is how you would generate the urlpatterns for them:
```python
_RESOURCES = [
Resource(
'developer',
'developers',
DeveloperViewSet,
[
NestedResource(
'language',
'languages',
ProgrammingLanguageViewSet,
parent_field_lookup='author',
)
],
),
]
urlpatterns = make_urlpatterns_from_resources(_RESOURCES)
```
For more examples of different relationships and authorization check the test
suite.
Changelog
=========
Version 2.0.0
-------------
Added support for Django 2.2 and removed support for Django < 2.2
Version 1.3
------------------
Updated dependencies and added coverage config
Version 1.2 Beta 3
------------------
Fixed error when urlconf was not explicitly set on the request
Version 1.2 Beta 2
------------------
Fixed support for non-session-based authenticators when checking permissions in
viewsets in the ancestry.
Version 1.2 Beta 1
------------------
Implemented ability to force a field value in a nested resource to be set to
the URL of an ascending resource. This is done using the optional attribute
``field_forced_to_ancestor`` on the serializer's ``Meta`` class.
Version 1.1
-----------
Re-worked the mechanism for URL generation to support cross-linking resource
trees.
**Breaking change**: Any previous usage of many-to-many fields on variables
in the current request's URL will now break.
Version 1.0 Release Candidate 3
-------------------------------
Added proper support for namespaced URLs
Version 1.0 Release Candidate 1
-------------------------------
Added support for Django 1.10 and Rest Framework 3.4.3
