Django api call in view unable to save for foreign key userId

What i am doing is django 2 project call api to django 1 project to book an appointment in Appointment table and save the details into BookAppt table.




I don't know what is the problem as i did say same post with the same value to that BookAppt table API and it works normally. But when saving using the API call, it gave me this error.

{"patientId":["This field is required."]}.

I have no idea why as i did put in the patientId field. Please help as i have been stuck at this part for 2 days now.

Here is my code:

Do note that it is django 2 calling to django 1

model.py

django 1

class Appointments (models.Model):      patientId = models.IntegerField()      clinicId = models.CharField(max_length=10)      date = models.DateField()      time = models.TimeField()      created = models.DateTimeField(auto_now_add=True)      ticketNo = models.IntegerField()        STATUS_CHOICES = (          ("Booked", "Booked"),          ("Done", "Done"),          ("Cancelled", "Cancelled"),      )      status = models.CharField(max_length=20, choices=STATUS_CHOICES, default="Booked")

django 2

class MyUser(AbstractUser):      userId = models.AutoField(primary_key=True)      gender = models.CharField(max_length=6, blank=True, null=True)      nric = models.CharField(max_length=9, blank=True, null=True)      birthday = models.DateField(blank=True, null=True)      birthTime = models.TimeField(blank=True, null=True)    class BookAppt(models.Model):      clinicId = models.CharField(max_length=20)      patientId = models.ForeignKey(MyUser, on_delete=models.CASCADE)      scheduleTime = models.DateTimeField()      ticketNo = models.CharField(max_length=5)      status = models.CharField(max_length=20)

serializer

django 1

class AppointmentsSerializer(serializers.ModelSerializer):        class Meta:          model = Appointments          fields = ('id', 'patientId', 'clinicId', 'date', 'time', 'created', 'ticketNo', 'status')

django 2

class MyUserSerializer(serializers.ModelSerializer):        class Meta:          model = MyUser          fields = ('userId', 'username', 'email', 'first_name', 'last_name', 'gender', 'nric', 'birthday', 'birthTime')          read_only_fields = ('userId',)      class BookApptSerializer(serializers.ModelSerializer):      patientId = MyUserSerializer(many=False)        class Meta:          model = BookAppt          fields = ('id', 'patientId', 'clinicId', 'scheduleTime', 'ticketNo', 'status')

view.py

django 1

class AppointmentsViewSet(viewsets.ModelViewSet):      permission_classes = [AllowAny]      queryset = Appointments.objects.all()      serializer_class = AppointmentsSerializer

django 2
