Newbie learning Rails. I'm currently on Chp9 here:
http://railstutorial.org/chapters/sign-in-sign-out#top
At the end of the tutorial, rails is erroring (see below). being new
to Rails and after having checked the tutorial... How do you resolve
this kind of error. It's saying current_user is not defined, and it is
supposed to be defined with/Sites/sample_app/app/helpers/
sessions_helper.rb
NameError in Pages#home
Showing /Users/iamme/Sites/sample_app/app/views/layouts/
_header.html.erb where line #6 raised:
undefined local variable or method `current_user' for #<#<Class:
0x103371258>:0x10336be70>
Extracted source (around line #6):

8: <% end %>
