Provide a default URL as a default if there hasn’t been a file uploaded
# File app/uploaders/photo_uploader.rb, line 73 def default_url "/images/default/" + ["faceless_avatar", "#{version_name}.png"].compact.join('_') end

# File app/uploaders/photo_uploader.rb, line 52 def store_dir "uploads/#{model.class.base_class.to_s.underscore}/#{mounted_as}/#{model.id}" end
