I'd also maybe add a try/catch to from_native, so that serialisation wouldn't fail pre-emptively, e.g.:

def from_native(self, value):
    try:
        val = json.loads(value)
    except TypeError:
        raise serializers.ValidationError(
            "Could not load json <{}>".format(value)
        )
    return val
