I'm using the following Rake task to traverse a directory tree and load images into a custom Rails photo gallery. Models are thus: Events have many Galleries which have many Prints (individual images). The admin user would create an Event, then choose which folder within the "uploads" folder to load images from. For each sub-folder in that folder, we create a new gallery and create a new print for each jpg in that sub-folder. These jpgs are attached to the new Print with Paperclip. After Prints are added to the new Gallery, we make the first Print's photo the main Gallery image and save it. Finally, we back up a directory and start on a new Gallery.

desc "Load files from upload directory"
task :load_galleries => :environment do
  dir = ENV["UPLOAD_DIR"]
  event = Event.find(ENV["EVENT_ID"].to_i)
  Dir.chdir(RAILS_ROOT + '/uploads/' + dir)
  Dir.glob('**').each do |d|
    Dir.chdir(d)
    g = event.galleries.create(:title => d.titleize)
    Dir.glob('*.jpg').each_with_index do |p, i|
      g.prints.create(:photo => File.open(p), :title => "#{g.title} ##{i + 1}" )
    end
    g.photo = g.prints.first.photo
    g.save
    Dir.chdir('..')
  end
end

Less noise

task :load_galleries => :environment do
  Event.find(ENV["EVENT_ID"]).load_galleries_from(ENV["UPLOAD_DIR"])
end
class Event < ActiveRecord::Base
  has_many :galleries

  def load_galleries_from(folder)
    Dir.glob(RAILS_ROOT + '/uploads/' + folder + '/**').each do |subfolder|
      galleries.create_from_folder(subfolder)
    end
  end
end
class Gallery < ActiveRecord::Base
  belongs_to :event
  has_many :prints
  has_attached_file :photo

  def self.create_from_folder(folder)
    gallery = create(:title => folder.titleize)
    gallery.create_prints_of_jpgs_in(folder)
    gallery.photo = prints.first.photo
    gallery.save
    gallery
  end

  def create_prints_of_jpgs_in(path)
    Dir.glob(path + '/*.jpg').each_with_index do |photo, i|
      prints.create(:photo => File.open(photo), :title => "#{title} ##{i + 1}" )
    end
  end

Thanks! I like Adam's because it really cleans up what I've got. But, now that I look at mainej's, I'm wondering if I should move more functionality into the models.

Sometimes pain can be made worse by social or work-related events that cause you stress – loss of a job. That's what i want to say here.
