Subject: Re: Newbie question: Referencing a class inside another class

Hello,

if you have required the content of lib/pkg/sample.rb into 
app/models/caller.rb, you can simply reference the class SampleError by 
its name. It is defined in the global namespace, unless in sample.rb the 
classes are in another module (in that case you have to proceed as Henry 
told you). To require the content, just use one of the functions in the 
require family in the top of your file caller.rb. This would look 
something like the following:

   require_relative '../../lib/pkg/sample.rb'

Note: require_relative requires the file relative from the file it's 
written in, unlike require, which looks through a specified set of 
directories ($LOAD_PATH) and takes the file from there.

regards,

Calvin
