Question

I use from django.contrib.auth.models import User in Django for Authentication.
I want update 1 column of auth_user table when any user login.

 @login_required 
 def showMag(request):
        return render(request,'index.html')

Answer 1

You could use user_logged_in signal

def login_additional_function(sender, user, request, **kwargs):
    # user -> The user instance that just logged in.
    user.changefield = field
    user.save()

user_logged_in.connect(login_additional_function)
