Mi modelo de la foto:

class Photo < ActiveRecord::Base 
    belongs_to :konkurrencer 
    attr_accessor :image_url, :billed_navn 
# Paperclip.options[:command_path] = "/usr/local/bin" 
    has_attached_file :image, 
      :storage => :s3, 
      :bucket => 'konkurrencerher', 
      :styles => { :original => ["300x250>", :png], :small => ["165x138>", :png], :mini => ["120x120>", :png] }, 
      :path => 'images/vind/:style/:id/:basename.:extension', 
      :url => ":s3_path_url", 
      :s3_credentials => { 
      :access_key_id => 'x', 
      :secret_access_key => 'x' 
    }

Funciona bien en mi servidor local.

estoy USNG la Heroku pila de bambú con la RM-1.9.2 y el verison de rieles es 3.0.9
