models.py

class Notification(BaseModel):
    created_user = models.ForeignKey(User)
    title = models.CharField(max_length=225)
    description = models.TextField(max_length=600)
    is_read = models.BooleanField(default=False)
    priority = models.CharField(max_length=20, choices=NOTIFICATION_STATUS, default=LOW)

Channels is the best solution for this usecase. It's websocket and truly async and that connect with your frontend and backend sync in realtime.

base.html

socket = new WebSocket("ws://" + window.location.host + "/notification/");
socket.onmessage = function(e) {
    notificationElement.innerHtml = e.data
}

models.py

@receiver(post_save, sender=Notification)
def notification_handler(sender, instance, **kwargs):
    Group("notification").send({
        "text": "This is the new notification",
    })
