How to patch several objects at the same time in Django Rest Framework?-CodePudding

I'm creating an app in which notifications model exists. That is why I need a behavior like this: when a person requests the notification page, the field is_read which is boolean turns from default FALSE to TRUE. The trouble is that there could be many of objects, so how to set to TRUE all of them?

Model:

class Notification(models.Model):
    is_read = models.BooleanField(default=False)
    notification_from = models.ForeignKey(Order, on_delete=models.CASCADE, related_name="notiffrom")
    notification_to = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name="notifto")

View:

class UserNotificationView(ListModelMixin, GenericAPIView, CreateModelMixin):

    serializer_class = NotificationSerializer

    def get_queryset(self):
        notification_to = self.kwargs["notification_to"]
        return Notification.objects.filter(notification_to=notification_to)


    def get(self, request, *args, **kwargs):
        return self.list(request, *args, **kwargs)

I know that there are bulk requests in Django but struggle with making them with DRF. Maybe there are some other ways?

CodePudding user response：

You could add the update function in the get_queryset function.

class UserNotificationView(ListModelMixin, GenericAPIView, CreateModelMixin):

    serializer_class = NotificationSerializer

    def get_queryset(self):
        notification_to = self.kwargs["notification_to"]
        queryset = Notification.objects.filter(notification_to=notification_to)
        queryset.update(is_read = True)
        return queryset

    def get(self, request, *args, **kwargs):
        return self.list(request, *args, **kwargs)
