рельсы - Методы модели, (Получение URL-адреса изображения PaperClip с S3)

Question

У меня есть приложение для рельсов 3 с скрепкой. Модель выглядит немного как:

class Attachment < ActiveRecord::Base 

    has_attached_file :attachment, 
        :styles => { 
         :large => '1024x758>', 
         :medium => "200x150#", 
         :thumb => "100x75#", 
         :small => "50x50>" 
        }, 
        :default_style => :original, 
        :default_url => '/images/:attachment/default_:style.png', 
        :path => ":instance_id/:attachment/:id/:style/:basename.:extension", 
        :storage => :s3, 
        :s3_credentials => File.join(Rails.root, 'config', 's3.yml'), 
        :s3_protocol => 'https', 
        :s3_permissions => :private, 
        :use_timestamp => false 

def authenticated_url(style = nil, expires_in = 90.minutes) 
    AWS::S3::S3Object.url_for(attachment.path(style || attachment.default_style), attachment.bucket_name, :expires_in => expires_in, :use_ssl => attachment.s3_protocol == 'https') 
end 

Это называется из user_mailer, который называется через delayed_job:

В user_mailer.rb почтовик это выглядит немного что-то вроде этого:

@comment.attachments.each do |a| 
    attachments[a.attachment_file_name] = open(a.authenticated_url()) {|f| f.read } 
    end 

Проблема здесь в том, что с задержкой отправителя с ошибкой:

Любая идея, что может быть b Продолжение?

В вашей модели необходимо require "aws/s3".
