[Radiant] Wierd issue with production vs. development

[Christopher Dwan]

Hey all,

I'm building a rake task to pull all my data from my production db  
(MySql) to my development db (SQLite). It works great pulling in that  
direction, but when I go to reverse the process, it fails. It has to  
do with my plugin that uses attachment_fu.

Basically, I have a model Asset that uses 'has_attachment'. This is  
the code that doesn't work:

"asset".classify.constantize

This is the error:
NoMethodError: undefined method `has_attachment' for Asset:Class

Any ideas what the difference is between production and development  
that would cause this to not work?  I can run the server in dev mode,  
I just can't run constantize. This error does _not_ happen in the  
production environment.  I've tried changing the contents of config/ 
environments/development.rb with no success.

Thanks!
