Question

I don’t understand why one method would work and the other would throw a NoMethodError if they come from the same lib file.

# app/views/bunnies/show.html.erb <% if logged_in? %>   <%= current_user.login %> |   <%= link_to 'Logout', logout_path %> |   <% if authorized? %>     <%= link_to 'Edit Details', edit_bunny_path(@broker) %> |   <% end %>   <%= link_to 'Back', bunnies_path %> <% end %> 

… throws a NoMethodError for authorized?. If I comment that if block out, the page works fine (with logged_in?).

# lib/authenticated_system.rb def logged_in?   !!current_user end  def authorized?   current_user.login == 'admin' end  # app/controllers/application.rb class ApplicationController < ActionController::Base   include AuthenticatedSystem end 

What gives?

Answer 1

Right, so I still don’t understand why that wasn’t working, but I have found an alternative solution.

(1) Leave authenticated_system.rb as is.

(2) Add a helper method to controllers/application.rb:

helper_method :is_admin? def is_admin?   if logged_in? && current_user.login == 'admin'     true   else     false   end end 

(3) Use the helper method instead of authorized?. If anyone would like to explain why the original code wasn’t working, I’m all ears!
