Django REST Framework PUT request to update an image

[Jessica Dyer]

I have managed to use the Django REST-framework to upload an image associated with an item. However, the PUT request throws an error (400) when attempting to update the image. Here is the code: 

• Model: 
  • image = models.ImageField(upload_to="images/", blank=True, null=True)
• Serializer: 
  • class ItemSerializer(serializers.ModelSerializer):

    class Meta:

    model = Item

    fields = "__all__"

• View:
• @api_view(["GET", "PUT"])
  def api_item_beta(request, pk):

  try:
  

  item = Item.objects.get(pk=pk)

   except Item.DoesNotExist:
  

  return Response(status=status.HTTP_404_NOT_FOUND)

  if request.method == "GET":
  

  serializer = ItemSerializer(item)

  return Response(serializer.data)

  elif request.method == "PUT":
  

  serializer = ItemSerializer(item, data=request.data, partial=True)

  if serializer.is_valid():

  serializer.save()

  return Response(serializer.data)

  return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

So, I can POST an image using this serializer. The PUT request works for everything EXCEPT the image. The image data is identical in both cases (where I am posting and putting). What am I missing that the serializer is expecting??

Any help much appreciated!
