Re: [Rails-core] How to access an engine's method from main application?

Hey Al,

This list is used for talking about Rails internals for people who are contributing to the Rails framework directly. You will need to post this question to another list. Spree maintains a page with community support links http://spreecommerce.com/community or you can try posting to http://stackoverflow.com. Glad that you're using Rails, hope you find an answer.

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!

Thanks for the pointer!
