What you want to achieve is possible, but you are thinking about it the wrong way. Do not call it a "global variable" --- that is not only the wrong word but refers to some other concept in Ruby which will not do what you think it will do.
Here's a great introduction to sessions & cookies with a detailed beginner explanation: http://www.theodinproject.com/ruby-on-rails/sessions-cookies-and-authentication when you're in a controller and you refer to session[:xyz] (see article above) that is not a local variable, but in fact a special construct by Rails to share information across web requests from the same user. It's already implemented for you -- use it, don't re-invent the wheel. -Jason On Sep 4, 2014, at 4:38 PM, António <[email protected]> wrote: > The second controller checks the variable for knowing whether a user is > logged in.
