Notification system [closed]

I have the following template:

from django.db import models
from django.utils.timezone import now

# Create your models here.
class Event(models.Model):
    name = models.CharField('nombre',max_length = 255)
    place = models.CharField('lugar',max_length = 255)
    thematic = models.CharField('tema',max_length = 100)
    title_of_the_paper = models.CharField('tema abordado',max_length = 60)
    date_event  = models.DateField('realizado el', auto_now_add=False)
    author = models.ForeignKey(
        'professor.Professor', related_name='eventos', on_delete=models.CASCADE)

    class Meta:
        verbose_name = 'evento'
        verbose_name_plural = 'eventos'
        db_table = 'event'

I want to implement a notification system, which when a user inserts an event that notifies me to all other users about the created event. What packet should I use as I can modify the view?

This is the view

def ajax_create_event(request):
    event_form = EventForm()
    if request.method == 'POST':
        name = request.POST['name']
        place = request.POST['place']
        thematic = request.POST['thematic']
        title_of_the_paper = request.POST['title_of_the_paper']
        date_event = request.POST['date_event']
        author = request.user.teacher_profile
        form = EventForm(request.POST, request.FILES)
        if form.is_valid():
            Event.objects.create(
                name=name, place=place, thematic=thematic,title_of_the_paper = title_of_the_paper,date_event = date_event, author=author
            )
            events = Event.objects.filter(author=author)
            data = {
                'msg': 'El evento se ha guardado satisfactoriamente',
                'page': render_to_string('event/list.html', {'events': events}, request=request),
                'header': render_to_string('event/dinamic_event.html', request=request),
                'event': request.user.teacher_profile.number_of_events
            }
        return JsonResponse(data)
    else:
        data = {
            'page': render_to_string('event/add.html', {'form': event_form}, request=request)
        }
    return JsonResponse(data)
