Django rest framework how to delete a model through it's serializer

I have such a scenario where I want to delete the saved model through its serializer: 

class SomeView(APIView):
  ...
  def post(self, request, context):
    serializer = MySerializer(data = request.data)
    # I need to save the model since I need the file field in the following processings
    if serializer.is_valid():
      serializer.save()
    try:
      ...
    except:
      # I need to delete the model in case of exception
      serializer.delete()

But there seems not to exist a way to delete the saved model through its serializer because I got this error AttributeError: 'VideoSerializer' object has no attribute 'delete'

The serializer.save() returns the saved object. 

instance = None
if serializer.is_valid():
  instance = serializer.save()
try:
  ...
except:
  instance.delete()

That should delete the object being saved.
