Hi,
I'm coming back with this one as well. I managed to fix my problem. In my
consumer, I was making normal Django database queries without the
@database_sync_to_async decorator.
As soon as I started wrapping my code properly with this decorator,
everything started to work fine. See below.
class NotificationConsumer (AsyncJsonWebsocketConsumer):
async def connect (self):
#do stuff
async def disconnect (self, code):
#do stuff
async def user_notification (self, event):
#do stuff
@database_sync_to_async
def get_notification (self, notification_pk):
return Notification.objects.filter(pk=notification_pk).first()
Hope this helps somebody else!
