How to alter the values of specific fields in HTML display form?

[Manish Shah]

I am having a nested serializer as:-

```

class DeviceConfigSerializer(serializers.ModelSerializer):

    config = serializers.JSONField()

    context = serializers.JSONField()

    class Meta:

        model = Config

        fields = ['backend', 'status', 'templates', 'context', 'config']

class DeviceDetailSerializer(serializers.ModelSerializer):

    config = DeviceConfigSerializer()

    class Meta(BaseMeta):

        model = Device

        fields = [

            'id',

            'name',

            'organization',

            'mac_address',

            'key',

            'last_ip',

            'management_ip',

            'model',

            'os',

            'system',

            'notes',

            'config',

        ]

   def update():

   ...

   ...

   ...

```

views:-

```

class DeviceDetailView(RetrieveUpdateDestroyAPIView):

    serializer_class = DeviceDetailSerializer

    queryset = Device.objects.all()

```

When I try to get the data, I receive this:-

But The data found in the HTML display form fields for the nested fields is not satisfactory:-

Can anyone help me with this?
PS: I have tried `to_represenation` and `to_internal_value` but that comes with it's problem.

The above problem gets resolved with the latest release of DRF i.e., ~3.12.0

It is mentioned about this issue in the first line itself here 3.12 Announcement
