JSON API support for Django REST Framework

• Documentation: http://django-rest-framework-json-api.readthedocs.org/
• Format specification: http://jsonapi.org/format/

By default, Django REST Framework will produce a response like:

{
    "count": 20,
    "next": "http://example.com/api/1.0/identities/?page=3",
    "previous": "http://example.com/api/1.0/identities/?page=1",
    "results": [{
        "id": 3,
        "username": "john",
        "full_name": "John Coltrane"
    }]
}

However, for an identity model in JSON API format the response should look like the following:

{
    "links": {
        "prev": "http://example.com/api/1.0/identities",
        "self": "http://example.com/api/1.0/identities?page=2",
        "next": "http://example.com/api/1.0/identities?page=3",
    },
    "data": [{
        "type": "identities",
        "id": 3,
        "attributes": {
            "username": "john",
            "full-name": "John Coltrane"
        }
    }],
    "meta": {
        "pagination": {
          "count": 20
        }
    }
}

As a Django REST Framework JSON API (short DJA) we are trying to address following goals:

1. Support the [JSON API](http://jsonapi.org/) spec to compliance
2. Be as compatible with Django REST Framework as possible e.g. issues in Django REST Framework should be fixed upstream and not worked around in DJA
3. Have sane defaults to be as easy to pick up as possible
4. Be solid and tested with good coverage
5. Be performant

1. Python (2.7, 3.4, 3.5, 3.6)
2. Django (1.11, 2.0)
3. Django REST Framework (3.6, 3.7, 3.8)

$ pip install djangorestframework-jsonapi

$ git clone https://github.com/django-json-api/django-rest-framework-json-api.git
$ cd django-rest-framework-json-api
$ pip install -e .

$ git clone https://github.com/django-json-api/django-rest-framework-json-api.git
$ cd django-rest-framework-json-api
$ pip install -e .
$ django-admin.py runserver --settings=example.settings

It is recommended to create a virtualenv for testing. Assuming it is already installed and activated:

$ pip install -e .
$ pip install -r requirements-development.txt
$ py.test

rest_framework_json_api assumes you are using class-based views in Django Rest Framework.

One can either add rest_framework_json_api.parsers.JSONParser and rest_framework_json_api.renderers.JSONRenderer to each ViewSet class, or override settings.REST_FRAMEWORK

REST_FRAMEWORK = {
    'PAGE_SIZE': 10,
    'EXCEPTION_HANDLER': 'rest_framework_json_api.exceptions.exception_handler',
    'DEFAULT_PAGINATION_CLASS':
        'rest_framework_json_api.pagination.JsonApiPageNumberPagination',
    'DEFAULT_PARSER_CLASSES': (
        'rest_framework_json_api.parsers.JSONParser',
        'rest_framework.parsers.FormParser',
        'rest_framework.parsers.MultiPartParser'
    ),
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework_json_api.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
    ),
    'DEFAULT_METADATA_CLASS': 'rest_framework_json_api.metadata.JSONAPIMetadata',
    'DEFAULT_FILTER_BACKENDS': (
        'rest_framework.filters.OrderingFilter',
    ),
    'ORDERING_PARAM': 'sort',
    'TEST_REQUEST_RENDERER_CLASSES': (
        'rest_framework_json_api.renderers.JSONRenderer',
    ),
    'TEST_REQUEST_DEFAULT_FORMAT': 'vnd.api+json'
}

This package provides much more including automatic inflection of JSON keys, extra top level data (using nested serializers), relationships, links, and handy shortcuts like MultipleIDMixin. Read more at http://django-rest-framework-json-api.readthedocs.org/
