How to create custom JSON payload structure in Django Rest Framework?

Question

I am creating an API that requires a custom structure for all JSON responses.

{
    code: 200,
    payload: [
        {...},
        {...},
        {...}
    ]
}

Where payloadcontains all the items returned by the request.

I created a custom Rendererone that extends JSONRenderer, but to access the response code I need to access render_context.

class VendorRenderer(JSONRenderer):
    def render(self, data, accepted_media_type=None, render_context=None):
        response = render_context['response']
        data = {
            'code': response.status_code,
            'payload': data
        }
        return super(VendorRenderer, self).render(data, accepted_media_type, render_context)

Is this a suitable place for this kind of wrapping, or should it happen somewhere else, such as a ViewSet, or by extending the Response object?
