Hi, I'm trying create a user system for a future project but I have a
problem when I want give to my users the "Welcome". This is my code:
#application_controller
class ApplicationController< ActionController::Base
protect_from_forgery
helper_method :current_user
private
def current_user_session
return @current_user_session if defined?(@current_user_session)
@current_user_session = UserSession.find
end
def current_user
@current_user = current_user_session&& current_user_session.user
end
end
#welcome_controller
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
<h1><%= @controller.hi %></h1>
I believe that my problem are in the variable that I'm use, but I have
tried with @user_session and nothing.
Assuming you want to display the text stored in @weli then you should be doing<%=
@weli %>
Fred
Anyone know?
Regards, Iván

Hi Fred, I want show @weli to my guest and @welr to my users, that is
why I use "if" and the variable @current_user, but, does not works.
Use current_user - you are only setting @current_user when
current_user is called.
Fred.

Ok, thanks, before If I changed all my @current_user in
/welcome_controller/ the webpage show me an error:
can't convert User into String
But I just noticed the error, and it was because User must be converted
in String with /.to_s/, what I was silly :(
One question more, now, this show me the welcome message correct but no
with the username, but with this:
<User:0xb6cd90f4>
How I can change it?
Regards, /Iván/
