current_user not working but user_signed_in is true

[Jeremy]

Hello,

I am a brand new Rails developer.  I am attempting to use Devise for authentication, but I'm running into an issue.

The default login seems to work.  I can create a new user and then login with those credentials (email/password).

I have a very simple controller for the home page that I'm using to test...

class HomeController < ApplicationController

  before_filter :authenticate_user!

  def index

    @user = current_user

  end

end

Then in my home view I'm trying to display the user information...

<% if user_signed_in? -%>

<p>signed in as <% current_user.id -%></p>

<p>user = <% @user.id -%></p>

<% end -%>

The if statement evaluates as true, but I just see...

signed in as

user =

In other words, the current_user doesn't work either in the view or in the controller, though I have put 'before_filter :authenticate_user!' into my controller.

I am a bit mystified at this point.

Here are my software versions...

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]

rails 3.2.7

devise 2.1.2

I may be missing something very simple here, but my understanding is that 'current_user' should be set if 'user_signed_in' is true.

Thanks for any help you can give on this.

Jeremy, first of all, why you need to show user's id instead of user email or something more reliable! To make sure that any content is going to show in your views you can't forget the equal symbol after the percentage. You should always do something like the snippet above, when you wish to show a output:

<%= current_user.email %>

I hope you get it! I also highly recommend you to read rails tutorial book on railstutorial.org to clarify your mind with some basics.

Hello,

Thanks for the replies! 

Indeed this was 100% operator error on my part.  I just ommitted the "=" to write to the page.
