views.py :
class MyModelCreateApiView(generics.CreateAPIView):
queryset = MyModel.objects.all()
serializer_class = MyModelSerializer
authentication_classes = (TokenAuthentication,)
def create(self, request, *args, **kwargs):
data = dict()
data['foreign_model_id'] = kwargs['pk']
foreign_model_obj = MyForeignModel.objects.get(id=data['foreign_model_id'])
obj = MyModel.objects.create(**data)
result = serialize_query(MyModel, {"id": obj.id})
local_time = foreign_model_obj.time
my_celery_task.apply_async([foreign_model_obj.id], eta=local_time) # send only the obj id
return Response(result)
tasks.py :

my_model_obj = MyModel.objects.get(id=mymodel_obj_id) # retrieve your object here
# ... updating obj attributes
