Rails accessing variable outside Devise controller

I am trying to access a variable passed in when a user (using Devise) signs in or signs out.

So I have edited the Devise Sessions controller (/controllers/devise/sessions_controller.rb) to setup a variable when a user logs in / out:

def create
@signed_in_token = "something"

However I now want to access this variable in /views/layouts/application.html.erb. It doesn't seem to be showing up...

The problem there that this actions are use redirect_to method after call. You can use flash obejct to pass variable to next render.

def create
   flash[:you_variable] ="test"

And than you can access it in view

<%= flash[:you_variable] %>
