I've deployed my rails application on a staging/production machine running Apache and Phusion Passenger but cannot get the Paperclip gem to load correctly (or at least to get the piece of the application working that uses it). Other gems seem to load fine and when I set config.cache_classes to false in the RAILS_ROOT/config/environments/staging.rb the rest of the application works fine. If it is set to true I get the following Passenger message in the browser (and apache error log) and cannot use the application at all:
Error message:
undefined method `validates_attachment_presence' for #<Class:0xb618e938>
Exception class:
NoMethodError
I've googled around for quite some time but cannot find a solution for this issue I am having. I hope I am not overlooking something obvious...
UPDATE 21/8: On the same box running the rails app with sudo script/server -b 17x.7x.16x.3x -e staging works fine. Could this be a permission problem and Passenger not being able to find the installed Paperclip Gem?
Hope you can give me some pointers, let me know if you need more info! Thanks Mark

OK, I've solved this by adding
require "paperclip"
to the image.rb class.
I am going with this workaround for now.
