问题 I am trying to figure out how to customize the django LoginView based on whether or not it's the user's first time logging on for the day. I have my LoginView currently set up so that it defaults to the LOGIN_REDIRECT_URL = "book:author" in my settings.py file. This works flawlessly.

What I'm trying to do is if this is the first time the user has logged in for the day, direct them
