session variables

Is there a way to concatenate a number onto a string and use that string in a session variable? I tried something like..

x = 1 session["user" + x] = user one

but nothing happen unless I use the session[:user] syntax. Is there a way around this so I can set the session[:user + x] variable?

Thanks in advance

session["user#{x}".to_sym]

FYI, it's generally not recommended to store whole objects in the session. It's much better to store just the ID and retrieve the object from the database when you need it.

session[:user_id] = @user.id

then in future page views

User.find(session[:user_id])

Thanks a lot. I am not using it for a whole object. I tried to make the example as simple as possible. Thanks for the advice though.
