Мне нужно получить информацию из Reservation, ReservationDetails и Product, но просто получить Reservation и ReservationDetails
У меня есть 3 модели
class Reservation(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
userReservation = models.ForeignKey(User, on_delete=models.CASCADE, default=1)
dateStart = models.DateTimeField(null=False, blank=False, default=datetime.now)
dateFinish = models.DateTimeField(null=False, blank=False, default=datetime.now)
date_Created = models.DateTimeField(auto_now_add=True)
date_Modified = models.DateTimeField(auto_now=True, db_index=True)
def __str__(self):
return str(self.id)
class DetailsReservation(models.Model):
Reservation = models.ForeignKey(Reservation, blank=False, on_delete=models.CASCADE, null=True, related_name='reservation_details')
product = models.ForeignKey(Product, blank=False, on_delete=models.CASCADE, null=True, related_name='products_reservation')
Quantity = models.IntegerField(null=False, blank=False, default=0)
userbyReserva = models.ForeignKey(User, editable=False, on_delete=models.CASCADE, default=1)
class Product(models.Model):
product_Description = models.CharField(max_length=255)
Quantity = models.IntegerField(null=False, blank=False, default=0)
Quantity_Max_Reservation = models.IntegerField(null=False, blank=False, default=0)
product_Comments = models.CharField(max_length=255)
size = models.CharField(max_length=10, null=True)
product_Status = models.BooleanField(default=True)
category = models.ForeignKey(Category, on_delete=models.CASCADE, null=True, related_name='products')
date_Created = models.DateTimeField(default=datetime.now, blank=True)
date_Modified = models.DateTimeField(default=datetime.now, blank=True)
И я попытался создать сериализаторы
class ReservationDetailsSerializers(serializers.ModelSerializer):
products = serializers.PrimaryKeyRelatedField(queryset=Product.objects.all(), required=False)
class Meta:
model= DetailsReservation
fields = ['Reservation', 'Quantity', 'userbyReserva', 'products']
class ReservationDetailsListSerializer(serializers.ModelSerializer):
reservation_details = ReservationDetailsSerializers(many=True)
class Meta:
model = Reservation
fields = ['id', 'userReservation', 'dateStart', 'dateFinish', 'reservation_details']
но в ответе это поле не отображается
[
{
"id": "6d87ba1c-61bc-41bd-80c8-31a51df8d32f",
"userReservation": 1,
"dateStart": "2018-09-16T17:19:34-05:00",
"dateFinish": "2018-09-16T17:19:35-05:00",
"reservation_details": [
{
"Reservation": "6d87ba1c-61bc-41bd-80c8-31a51df8d32f",
"Quantity": 1,
"userbyReserva": 1
>>"here should show this information product"
}
]
},
{
"id": "0ed26395-2579-4c40-9a63-460f5095ac51",
"userReservation": 2,
"dateStart": "2018-09-16T19:21:24-05:00",
"dateFinish": "2018-09-16T19:21:24-05:00",
"reservation_details": [
{
"Reservation": "0ed26395-2579-4c40-9a63-460f5095ac51",
"Quantity": 1,
"userbyReserva": 2
}
]
}
]
, и это мои views.py
class getAllReservationDetails(generics.ListCreateAPIView):
queryset = Reservation.objects.prefetch_related('reservation_details')
print(queryset.query)
serializer_class = ReservationDetailsListSerializer
def get_object(self):
queryset = self.queryset()
obj = get_object_or_404(queryset)
return obj
Я рассматриваю это Ссылка , ноя не знаю, почему не показывает информационный продукт.
Но это не работает, как я хотел.
Что мне делать?
