send template data from signal in django

Question

As soon as the django user_logged_in signal works, I want to send data to my template at that moment.I need to check if my signal is working.

from django.contrib.auth.signals import user_logged_in
@receiver(user_logged_in)
def post_login(sender, user, request, **kwargs):
    isLogged = True    
    # base.html    

I want to send this to 'isLogged= True' base.html I don't know if I can do this with context processor.I just want to send data to base.html file as soon as user logs in
