Double create

Hi, i read topic about sending messages and notice that you used objects.create() to create instance of Person class. And then you send it to kafka. Consumer save it to db using save/create method of DRF serializer. But if i`m right method objects.create() also save object to db. So why we didn`t use simple construction joe = Person(first_name='Joe', last_name='Schmoe') and send joe to kafka?
