Description (last modified by )
Django==3.2.13
asgiref==3.5.2
If you will try to decorate any ORM function with sync_to_async you will wait forever.
asgiref==3.5.0 works fine
# models.py class DTOManager(models.Manager): @sync_to_async def filter(self, *args, **kwargs) -> list[BaseModel]: return [self._dto_mapper(i) for i in self.model.objects.filter(*args, **kwargs)] @sync_to_async def get(self, *args, **kwargs) -> BaseModel: try: return self._dto_mapper(self.model.objects.get(*args, **kwargs)) except self.model.DoesNotExist: raise ObjectNotFound(f"{self.model.__name__} not found") class Hotel(models.Model): id = models.UUIDField(primary_key=True, editable=False) coordinates = models.PointField(null=True) dto_objects = DTOManager(dto_mapper=lambda hotel: HotelDTO(**hotel.curated_data) if hotel else None) objects = models.Manager() # services.py hotels = await Hotel.dto_objects.filter(id=12)
