Rails - Mar 2005 - App behaves differently on Apache and Webrick

When running on the Webrick server (script/server), my app works fine. 
When running on Apache 2.0.52, I get the dreaded ''unitialized constant 
Merge'' error. Merge is the name of my model, the controller is 
MergesController.

The deadline looms, any help appreciated!

Thanks!

   JJ

Anyone?

I can post code, but don''t see the need since it works okay with 
Webrick. I also just installed the app on WindowsXP running XAMPP, and 
get the same results with Apache. Haven''t tried Webrick on that box, 
but will shortly.

Thanks in advance!

Regards,
   JJ

Okay, I fixed this, but I would think it''s an undocumented feature in 
dependencies.rb (or elsewhere).

I set a breakpoint here (dependencies.rb, around line 56)
     def const_missing(class_id)
       begin
breakpoint
        require_or_load(class_id.to_s.demodulize.underscore)

in IRB I did:
class_id.to_s.demodulize.underscore
"merge"
so far so good.
I tried:
require_or_load(class_id.to_s.demodulize.underscore)
and it barfed with a load error on another module of mine, 
gkntag/cutparts, which is required in merge.rb.
As I said, this runs fine under Webrick.
I changed the requires in merge.rb to:
require RAILS_ROOT + ''gkntag/cutparts''
require RAILS_ROOT + ''gkntag/filepair''

and it works fine under Apache and Webrick. My partial directory 
structure:

vcon/
	gkntag/
		cutparts.rb
		filepair.rb
	app/
		models/
			merge.rb

The webrick server is pretty persistent in ensuring that the PWD is 
RAILS_ROOT. This may be related to your issue.

I was under the impression that your non-Rails Ruby code should reside in your 
application''s lib/ folder, which is added to Ruby''s load path.
