Rails - Aug 2007 - Strangest restful_authentication 'unidentified method' error

Hi.  My head is about to explode on this one.

I am using restful_authentication and added a method to
lib/authentication_system.rb like so:

module AuthenticatedSystem
  protected
    def logged_in?
      current_user != :false
    end

    def role_at_least(role)
      return true
    end
...
end


The method "logged_in?" that came with the plugin is always found and
works.  But when I call role_at_least() it always returns:

undefined method `role_at_least'' for
#<#<Class:0x38909f4>:0x38909cc>


I have pulled all my hair out and tried just about everything.
Restarted the webrick, tried mongrel, restarted my machine even...

If I remove the logged_in? definition I get the expected "undefined
method `logged_in?'' " message.  I then put it back and it works
perfectly, but role_at_least has never been visible.  I even tried
removing the parameter to see if it would make any difference but I
similarily get:

undefined local variable or method `role_at_least'' for
#<#<Class:0x39efc28>:0x39efc00>

I would really appreciate any help or tips on how I can further debug
this.

Thanks, Chad.

Look a bit further in the code:

     def self.included(base)
       base.send :helper_method, :current_user, :logged_in?
     end

You''ll need to add your role_at_least method to this list. This  
includes the methods as ActionView helper methods.


Best regards

Thanks Peter, that solved my problem.  I feel like a bit of an idiot 
because I did grep the source tree for logged_in? to see where else it 
may be being declared or otherwise used but I completely missed it in 
"included".  Going to go brush up on modules in Ruby now :)
