How to known user status (login OR logout)

[Sergey Zhuravlov]

Hi

Does anybody know how to derermine whether a user is logged in the
system?
For this we use a database query?

Required for integration with IP PBX.

Thanks

During a request in rails, the 'current_user' variable is available to tell you who the current user is.

If you have an external system and are wanting to know if a user is logged in, you could query the Users table. There are a few columns that might be of interest:

* last_login_at

* last_request_at

These return timestamp values (in postgres at least).

Regards,

Steve

Yes I need to know when the case of the third-party system, and learn
best by a database query.

Is it possible to date the last login to the system to find out
whether the user NOW?

Similarly to the last request?

Or any requests made ​​permanent, if a user in the system?

If so, this will do.


Thank you!

I think the closest you can get is "last_request_at" which would be the last time the user clicked a link that fired off a request to the server.

It's a hard question to answer on any web based system without connecting the server and client in some form of live polling.

After logging in actually changing the value "last_request_at"
However, if the user is in the system, but not make any action with
values ​​nothing more happens
Only when the user logs out again updated "last_request_at"

So more or less accurately establish whether the logged user is not
it?
