I upgraded my Rails app from 1.0 to 1.1.2. Basically everything worked
on my development box. When I uploaded the changes (including the
frozen 1.1.2 gems) to my webhost most things worked. However I had a
problem with my application_helper.rb file. It wasn't able to find the
url_for_image_column method from the file_column plugin. Here's the
relevant code in applicaiton_helper.rb:

# this tag helper creates a image tag for file_column fields that
contain images
def image_tag_for_image_column(object, method, version, options = {})
  options = if options.nil?
  options[:size] = object.dimensions_for(version)
  image_tag(url_for_image_column(object, method, version), options)

I added the following line to the top of application.rb:

and now my application works.

Anyone have any ideas why I had to do this on my production
installation and not on the development installation?
