Fail to call

Distriker · June 9, 2011, 4:26pm

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

#user_sessions_controller class UserSessionsController < ApplicationController def new @user_session = UserSession.new end def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Estás dentro de nuestro sistema" redirect_to root_url else render :action => 'new' end end def destroy @user_session = UserSession.find @user_session.destroy flash[:notice] = "Usted está fuera de nuestro sistema" redirect_to root_url 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.

Anyone know?

Regards, Iván

Assuming you want to display the text stored in @weli then you should be doing <%= @weli %>

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.

Regars, *Iván*

Use current_user - you are only setting @current_user when current_user is called.

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.

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.
