i want to use django signals to identify if a user is logged-in twice and if so, revoke his first session so that only one user session can be present at once.
i used the following example but it seems that my signals.py does not even gets reconcnized and i dont know why.
Example: How to prevent multiple login in Django
accounts/signals.py
from django.contrib.auth import user_logged_in
from django.dispatch.dispatcher import receiver
from django.contrib.sessions.models import Session
from .models import UserSession
@receiver(user_logged_in)
def remove_other_sessions(sender, user, request, **kwargs):
# remove other sessions
Session.objects.filter(usersession__user=user).delete()
# save current session
request.session.save()
# create a link from the user to the current session (for later removal)
UserSession.objects.get_or_create(
user=user,
session=Session.objects.get(pk=request.session.session_key)
)
accounts/models.py
# Model to store the list of logged in users
class UserSession(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
session = models.OneToOneField(Session, on_delete=models.CASCADE)
accounts/apps.py
from django.apps import AppConfig
class AccountsConfig(AppConfig):
name = 'Accounts'
def ready(self):
import Accounts.signals
but for some reason nothing gets written onto the database for that table.
do i maybe miss something here, this is the very first time i get in touch with signals so i might missed something at the configuration.
