Django Rest Framework : Nested Serializer not working - django

Question

I have almost tried everything but am not able to reach at the point
model.py file
class RecievingImages(models.Model):
"""Original and Masked Images"""
....
name = models.CharField(max_length = 100, unique = True, primary_key=True)
area = models.IntegerField()
number = models.IntegerField()
agency_name = models.CharField(max_length=100, default='general')
rawImage = models.ImageField(upload_to=imageNameForRawImage,)
...
class UpdationImages(models.Model):
""" Update Image wrt name"""
....
name = models.ForeignKey(RecievingImages, on_delete=models.PROTECT, related_name='updated')
updated_image = models.ImageField(upload_to=UpdatedImageFolder,)
updated_image_url = models.TextField(default='None')
....
serializer.py
class UpdatedImageSerializer(serializers.ModelSerializer):
class Meta:
model = UpdationImages
fields = ('name', 'updated_image', 'updated_image_url')
class RecievingImagesSerializer(serializers.ModelSerializer):
updated = UpdatedImageSerializer(many= True, read_only=True)
class Meta:
model = RecievingImages
fields = ('updated','name','area','number','agency_name', rawImage)
I have used related_name in the model and also following the documentation along with that with many = True
But still in serializer.data updated does not show
views.py
class MappingSinglePhoto(APIView):
""" Mapping Single Image """
def post(self, request):
try:
data = request.data
# import pdb; pdb.set_trace()
name_of_image = data['name']
mapped_images_qs = UpdationImages.objects.select_related('name').filter(name = name_of_image)
for image in mapped_images_qs:
serializer = RecievingImagesSerializer(instance = image)
pdb.set_trace()
serializer.data
# return Response(serializer.data)
except Exception as e:
print(e)
NOTE
if I use depth=1 then it's working fine, but I am not looking for all the fields that depth displays.
Thanks & Regards

Thanks to #ArakkalAbu
There was a problem in query views.py
class MappingSinglePhoto(APIView):
""" Mapping Single Image """
def post(self, request):
try:
data = request.data
# import pdb; pdb.set_trace()
name_of_image = data['name']
mapped_images_qs = RecievingImages.objects.filter(name = name_of_image)
for image in mapped_images_qs:
serializer = RecievingImagesSerializer(instance = image)
pdb.set_trace()
serializer.data
# return Response(serializer.data)
except Exception as e:
print(e)
