Cannot query "HealthData object (1)": Must be «CardioActivity» instance?

У меня есть класс с generic во views, и мне нужно помимо объекта с которым работает это представление обновить также другой объект, но при попытке это сделать я получаю ошибку. Она возникает при обращении к HealthData в методе perform_create

views.py
class UserCardioactivity(generics.ListCreateAPIView):
    queryset = CardioActivity.objects.all()
    serializer_class = CardioSerializer

    def list(self, request):
        '''List of cardioactivites for concrete authorized user'''
        queryset = CardioActivity.objects.filter(health_model=request.user.health_data)
        serializer = CardioSerializer(queryset, many=True)
        return Response(serializer.data)

    def perform_create(self, serializer):
        '''Associating health_model with user'''
        HealthData.objects.get(health_data=self.request.user.health_data).update(
                                                            heart_rate_alone=self.queryset.heart_rate_alone,
                                                            blood_pressure_sys=self.queryset.blood_pressure_sys,
                                                            blood_pressure_dia=self.queryset.blood_pressure_dia)
        return serializer.save(health_model=self.request.user.health_data)


models.py
class CardioActivity(models.Model):
    health_model = models.ForeignKey(HealthData, on_delete=models.CASCADE, related_name='health_data')

    measuring_date = models.DateTimeField(auto_now=True)

    heart_rate_alone = models.PositiveSmallIntegerField(null=True, blank=True, validators=[MinValueValidator(40),
                                                                                           MaxValueValidator(280)],
                                                        verbose_name=_('heart rate alone'),
                                                        help_text=_("heart rate alone"))
    blood_pressure_sys = models.PositiveSmallIntegerField(null=True, blank=True, validators=[MinValueValidator(80),
                                                                                             MaxValueValidator(320)],
                                                          verbose_name=_('blood pressure systolic'),
                                                          help_text=_("blood pressure systolic"))
    blood_pressure_dia = models.PositiveSmallIntegerField(null=True, blank=True, validators=[MinValueValidator(40),
                                                                                             MaxValueValidator(230)],
                                                          verbose_name=_('blood pressure diastolic'),
                                                          help_text=_("blood pressure diastolic"))

Класс HealthData, на который ссылается данный класс, так же ссылается на user (OneToOneFiled)
