I think http://guides.rubyonrails.org/action_controller_overview.html#session
pretty much covers it. It is very simple as can be seen in the
examples there. Just set a value in the session in the controller
(something like session[:current_user_id] = user.id for example) and
access it again in a later action. Initially at least you can just
leave all the session config stuff at default and just go ahead and
use it.
