How to serve TextField as literal JSON without escaping with Django REST Framework?

We're storing raw JSON data in our model via a TextField and would like that data to be served by the REST Framework API.

The content is gettings escaped and rendered as a string rather than as part of the object. e.g. {\r\n \"phases\": [\r\n \"S etc

from requirements.txt

    Django==1.8.2
    djangorestframework==3.1.3

Screenshot for reference.

Added the following to my serializer (and import json at the top of my urls.py)

def to_representation(self, instance):
  ret = super(RoadmapSerializer, self).to_representation(instance)
  ret['jsonField'] = json.loads(ret['jsonField'])
  return ret

nb: jsonField is the name of the model attribute declared in models.py

jsonField = models.TextField(verbose_name="JSON", blank=True)

Sources of inspiration - django-rest-framework: How Do I Serialize a Field That Already Contains JSON? (answers by Almalki and Denis Cornehl) - http://www.django-rest-framework.org/topics/3.0-announcement/#serializers (since transform_ was deprecated in drf 3.0)
