Help on passing model field as function argument

Hi All,

Views.py :

class DASDataViewSet(viewsets.ModelViewSet):
    queryset = DASData.objects.all()
    serializer_class = DASDataSerializer

    def create(self, request, *args, **kwargs):
        try:
            das_data = {
                'patient': request.data['patient'],
                'hexa_data': request.data['hexa_data'],
                'device_id': request.data['device_id'],
            }
            serializer = DASDataSerializer(data=das_data)
            if serializer.is_valid():
                serializer.save()
                self._numeric_conversion(serializer)
                #self._start_monitoring(request.data['patient'])
            return Response("Success", status=status.HTTP_201_CREATED)
        except DASData.DoesNotExist:
            return Response("Failed to persist device data", status=status.HTTP_400_BAD_REQUEST)

    @staticmethod
    def _start_monitoring(patient_id, presentation_mode):# should be like this

        with open(os.path.join(constants.LOG_DIR, "%s.lck" % str(patient_id)), 'w+'):
            pass
        p = Pipeline()
       # p.startmonitor(patient_id)
        p.startmonitor(patient_id, presentation_mode) # should be like this

-----------------------------------------------------------------------------------------------------------

models.py:

class Patients(models.Model):
    GENDER_CHOICES = (
        ('M', 'Male'),
        ('F', 'Female'),
    )
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=255)
    gender = models.CharField(max_length=1, choices=GENDER_CHOICES)
    age = models.IntegerField()
    height = models.IntegerField()
    weight = models.DecimalField(max_digits=5, decimal_places=2)
    bmi = models.DecimalField(max_digits=5, decimal_places=2, null=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    presentation_mode = models.CharField(max_length=20, default='sleeping')

Doubt :

In the view.py, i would like to add "presentation_mode" in  p.startmonitor(patient_id) like p.startmonitor(patient_id, presentation_mode) but "presentation_mode" is the field of Patients model as shown above but DASDataViewSet we are using "DASData" model.

How can i fetch "presentation_mode" as argument to p.startmonitor(patient_id) which is field of Patients model.?

Thanks,

Saswat
