Need Advise on the best way to track how much time a user is logged in.....

[7equiv...@gmail.com]

I have created a model that gives me a time stamp  when a user logs in. I connected the 'user_logged_in signal' to a function:

def update_user_login(sender, user), **kwargs):
    user.userlogin_set.create(timestamp=user.last_login)
    user.save()

So this basically helps me track the login time, but how do I set the timestamp to the last_logout? There is no last_logout attribute like there is with last_login?

You cannot. The only thing you can do is to try and identify sessions.
A session starts when someone logs in, and stops when they stop using
the site.

Since a session only ends when someone stops using the site, the end
of a session cannot be recorded during a request, and therefore
session/usage analysis must be done outside of the request-response
life cycle.

IE, this needs to be a separate application that analyses the time and
user information that you log on each request.

Cheers

 I notice the Django.contrib.Auth has a logout function, is there anyway to connect a timestamp to a model when the user uses the logout function? My users will be using the log out function. This is for a time clock I'm building using RFID tags.

My users will not be able to logout by closing a browser because they have no such interaction with the system. They will be passing an RFID tag over a reader to unlock the door and clock in and a python script will handle the loging in and out. So if I can get the logout to time stamp a database entry I'll be good.

So they will present the RFID Tag to the reader at the time of login .....and logout also? You could do this directly in Python then....Capture the logout read (same way as login) and use the datetime module to generate the current time and save it in the Database.

Just trying to understand what is the Django bit here?

Am I just missing your point or you are actually defining a website with a login function and a logout function? If so, in the view for login, just call

    user.userlogin_set.create(timestamp=datetime.datetime.utcnow())

and in the logout view, just call

    user.userlogout_set.create(timestamp=datetime.datetime.utcnow())
