So I finally got a workaround in my own way falling back to the basics as I didn’t find any way to do it in a DRF way. I hope this answer is helpful to the Django community. I kept my model and serializers same changing the views to iterate over every image and save it using the serializer.
views.py
class ImageView(APIView):
parser_classes = (MultiPartParser, FormParser)
def get(self, request):
all_images = Image.objects.all()
serializer = ImageSerializer(all_images, many=True)
return JsonResponse(serializer.data, safe=False)
def post(self, request, *args, **kwargs):
property_id = request.data['property_id']
# converts querydict to original dict
images = dict((request.data).lists())['image']
flag = 1
arr = []
for img_name in images:
modified_data = modify_input_for_multiple_files(property_id,
img_name)
file_serializer = ImageSerializer(data=modified_data)
if file_serializer.is_valid():
file_serializer.save()
arr.append(file_serializer.data)
else:
flag = 0
if flag == 1:
return Response(arr, status=status.HTTP_201_CREATED)
else:
return Response(arr, status=status.HTTP_400_BAD_REQUEST)
helpers.py
def modify_input_for_multiple_files(property_id, image):
dict = {}
dict['property_id'] = property_id
dict['image'] = image
return dict
models.py
class Image(models.Model):
property_id = models.ForeignKey(
'properties.Address',
null=False,
default=1,
on_delete=models.CASCADE
)
image = models.ImageField(upload_to=directory_path)
serializers.py
class ImageSerializer(serializers.ModelSerializer):
class Meta:
model = Image
fields = (
'property_id',
'image'
)
The request comes in the form of querydict. The line images = dict((request.data).lists())['image'] coverts query dict to python dict and then looping over the array under the 'image' key.
The postman request looks like below:

property_id = models.ForeignKey(
'properties.Address',
null=False,
default=1,
on_delete=models.CASCADE

image = models.ImageField(upload_to=directory_path)
serializers.py
class ImageSerializer(serializers.ModelSerializer):
class Meta:
model = Image
fields = (
'property_id',
'image'

views.py
class ImageAPIView(ListCreateAPIView):
queryset = Image.objects.all()
serializer_class = ImageSerializer
def post(self, request, *args, **kwargs):
property_id = request.data['property']
form_data = {}
form_data['property']= property_id
success = True
response = []
for images in request.FILES.getlist('images'):
form_data['images']=images
print(form_data)
serializer = PropertyImageSerializers(data=form_data)
if serializer.is_valid():
serializer.save()
response.append(serializer.data)
else:
success = False
if success:
#return Response(response, status=status.HTTP_201_CREATED)
return Response({
'status' : 1,
'message' : 'Success',
'Data' : response,
})
#returnResponse(response,status=status.HTTP_400_BAD_REQUEST)
return Response({
'status' : 0,
'message' : 'Error!',
})

Solution for you should be using ListCreateAPIView. You dont have to implement your own view and handle everything.
class ImageView(generics.ListCreateAPIView):
parser_classes = (MultiPartParser, FormParser)
queryset = Image.objects.all()
serializer_class = ImageSerializer
def get_serializer(self, *args, **kwargs):
if isinstance(kwargs.get('data', {}), list):
kwargs['many'] = True
return super(CreateListModelMixin, self).get_serializer(*args, **kwargs)
