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?
What is the name of the attribute on User that holds the name? If
it's called name, then you would do @current_user.name in your erb
block.
Walter
Hi Walter, I think that it's current_user_session.user, but this
don't work, because show me the same. I'm trying make a call or
something, but nothing.
Regards, Iván
current_user_session.user gets you the current instance of the User
model, so you need to look inside that for the name attribute. If it's
called first_name, for example, then you would use
current_user_session.user.first_name as your value. If it's called
name, then change first_name to name. You want the value of a specific
property of that instance object, not the object itself. That's the
part you've been chasing your tail about here.
