[Rails] Very weird issue - Function not being recognized in template?

[softwareengineer 99]

I created a function before going to dinner and placed it in application.rb. Something like:
  
  def at_home
     ...
  end
  
  Then I called it from my .rhtml file like:
  
  <% if at_home %>
  .....
  <% end %>
  
  The function was working perfectly (I tested it before leaving). When I got back I keep getting
  
  
undefined local variable or method `at_home' for #<#<Class:0xb6e92960>:0xb6e92898

The weird thing is that I am calling the same function in my controller and it does not raise this error there?

The only other thing happened is that I rebooted the server.

So my question is does any one have an idea why something like this would happen? Why is my function in application.rb being recognized by the controller but not being recognized by my template 

  Thoughts and ideas are greatly appreciated.
  
  Thanks
  Frank
