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. :wink:

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. :slight_smile:

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 | #
