Question

I’m trying give a “Welcome Message” to my users with that:

 #welcome_controller.rb
    class WelcomeController < ApplicationController
      def hi
        @current_user
        if (@current_user)
          @welr = '¡Bienvenido' + current_user + ' a nuestra web!' 
        else
          @weli = "¡Bienvenido invitado, no dude en registrarse!"
        end
      end
    end
 #hi.html.erb Only the call
    <%= hi %>

When I initialize my server the controller give me this message:

undefined local variable or method `hi’ for

I have tried many wways of repairing this but I can’t.
