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)
