[Rails] "Remembering" link to redirect to after logging in

[Francesc Esplugas]

For doing this I usually use a session[]. The user tries to login, and if 
it's not authenticated the authentication method stores the 
"intended_controller" in a session[]. Then when the user logs in the 
system the login method redirects to the previously intended controller.

Hope that helps,

Francesc

##########################################
# The Admin controller
##########################################

   before_filter :authentication

   def authentication
     unless session[:user]
       session[:intended_controller] = '/admin/' + controller_name
       redirect_to :controller => '/account'
     end
   end

#########################################
# The account controller
#########################################

def login
   # Here comes the login code ...
   if # login is successful ...
     redirect_to session[:current_page]
   else
     redirect_to '/account/login'
end
