Rails core - Jun 2012 - How to access an engine's method from main application?

Hi,

I''m not sure if this is the right place to post this, but please
redirect
me if I''m posting this in the wrong place.

I''m trying to use a method defined in an engine''s library,
specifically it
is the current_order method from the Spree::Core 
engine: 
https://github.com/spree/spree/blob/master/core/lib/spree/core/current_order.rb 

In my view, I''ve tried 

Spree::Core::CurrentOrder.
current_order 

Using just "current_order" in development works fine though, but not 
in production. 

So then I''ve tried to require it in my views file like this: 

require ''spree/core/current_order'' 

I''ve also tried permutations of these other solutions: 

http://stackoverflow.com/questions/11124447/how-to-incorporate-rails-engine-applicationcontroller-methods-in-a-main-app

http://stackoverflow.com/questions/7323327/a-way-to-add-before-filter-from-engine-to-application/

http://stackoverflow.com/questions/8797690/rails-3-1-better-way-to-expose-an-engines-helper-within-the-client-app

But I''ve lost track of what I actually did. 

Can someone please point me in the right direction? Maybe I 
implemented the solutions in the above links incorrectly? 

This is the error I''m getting in production: 

2012-06-21T09:59:08+00:00 app[web.1]: ActionView::Template::Error 
(undefined method `current_order'' for 
Spree::Core::CurrentOrder:Module): 

If I comment out the lines of code with current_order, everything 
works in production. 

I''m thinking it''s the way things are loaded in production? But
this is
the first time I''m trying to deploy so I don''t quite
understand the
differences between development and production.   I''m not sure if it 
matters, but I''m deploying on Heroku.

Thanks in advance!

Hey Al,

an answer.

Thanks Richard.  Do you happen to know of any q&a forum specific for rails 
users?

Thanks for the pointer!
