Overview

JSON API support for Django REST Framework

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
        }
    }
}

$ py.test

Usage

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

Settings

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.PageNumberPagination',
    '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',
}

If PAGINATE_BY is set the renderer will return a meta object with record count and a links object with the next and previous links. Pages can be specified with the page GET parameter.

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/
