Rails - Aug 2006 - Absolute path to public/images in rake task?

Hi all

I''m trying to create a rake task for the first time, so please be a bit
patient with me. ;-)

I''m coding a photo gallery. Every photo gallery''s photos are
in its own
folder, and after an update I''d like to be able to synchronize the
photo
files with the database (because every photo has its own Photo class 
object). I''ve got so far:

# File tasks/photo_gallery.rake:
desc ''Synchronizes the photos of the galleries.''
task :synchronize_photo_galleries => :environment do
  puts ''--- Beginning with synchronization ---''
  PhotoGallery.synchronize_photos
  puts ''--- Synchronization done ---''
end

# File app/models/photo_gallery.rb
class PhotoGallery < ActiveRecord::Base
  # associations...

  def self.synchronize_photos
    photo_galleries = PhotoGallery.find :all
    photo_galleries.each do | photo_gallery |
      Dir.foreach("/images/photo_galleries/first_gallery") do | x | # 
Iterate through the dir of photos files...
        puts "Got #{x}"
      end
    end
    nil
  end
end

When running rake synchronize_photo_galleries I sadly get the following 
error:

rake aborted!
No such file or directory - /images/photo_galleries/first_gallery

The problem is clear to me -  the path can''t be right - but how can I 
fix it? Where do I get the absolute path of the public/images directory 
from?

Thanks a lot for help. :-)
Joshua

Joshua-

	You need to add RAILS_ROOT to the path in order to get the absolute  
path to your dir.

  Dir.foreach("#{RAILS_ROO}/public/images/photo_galleries/ 
first_gallery") do | x | #
