I have a file my_library.rb in the lib folder.
class MyLibrary
def auth(username,password)
end
end
I know it doesn''t do anything yet, but I wanted to eliminate the
possibility of errors in the method.
class MyController < ApplicationController
require ''my_library''
def index
MyLibrary.auth("username","password")
end
...
end
As I try to invoke the auth method from the controller above I get
this exception:
NoMethodError in Person summary requestsController#index
undefined method `auth'' for MyLibrary:Class
RAILS_ROOT: /Users/peterivie/AptanaProjects/AMC
Application Trace | Framework Trace | Full Trace
app/controllers/person_summary_requests_controller.rb:16:in `index''
-e:2:in `load''
-e:2
I also tried MyLibrary::auth("username","password")
I am new to Ruby so I am probably missing something obvious. I am
trying to create some code to download xml from a (non-rails) REST API.

Thanks for the quick response. Your suggestion and a server reboot fixed it. That''s probably something I would understand better if I had payed more attention in my class on object oriented programming years ago. I will assume the difference is that class methods can be called without creating an actual object (or instance of the class). That makes sense. Thanks again, I should have asked about 4 hours of head beating ago. On Apr 9, 12:04 pm, "David A.
