Renderers

Setting the renderers

The default set of renderers may be set globally, using the DEFAULT_RENDERER_CLASSES setting. For example, the following settings would use JSONP as the main media type and also include the self describing API.

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework_jsonp.renderers.JSONPRenderer',
    )
}

You can also set the renderers used for an individual view, or viewset, using the APIView class based views.

from django.contrib.auth.models import User
from rest_framework.response import Response
from rest_framework.views import APIView
from rest_framework_jsonp.renderers import JSONPRenderer

class UserCountView(APIView):
    """
    A view that returns the count of active users in JSONP.
    """
    renderer_classes = (JSONPRenderer,)

    def get(self, request, format=None):
        user_count = User.objects.filter(active=True).count()
        content = {'user_count': user_count}
        return Response(content)

Or, if you're using the @api_view decorator with function based views.

@api_view(['GET'])
@renderer_classes((JSONPRenderer,))
def user_count_view(request, format=None):
    """
    A view that returns the count of active users in JSONP.
    """
    user_count = User.objects.filter(active=True).count()
    content = {'user_count': user_count}
    return Response(content)

API Reference

JSONPRenderer

Renders the request data into JSONP. The JSONP media type provides a mechanism of allowing cross-domain AJAX requests, by wrapping a JSON response in a javascript callback.

The javascript callback function must be set by the client including a callback URL query parameter. For example http://example.com/api/users?callback=jsonpCallback. If the callback function is not explicitly set by the client it will default to 'callback'.
