CarrierWaveとSidekiqでのバックグラウンドジョブを使用したS3への直接アップロードに関するRyanBatesチュートリアルに従います。

sidekiqログのバックグラウンドワーカーに次のエラーが表示されます。

これが私のアップローダーです

class ImageUploader < CarrierWave::Uploader::Base
  # Include CarrierWave direct uploader to background upload task.
  include CarrierWaveDirect::Uploader

  # Include RMagick or MiniMagick support:
  include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Include the Sprockets helpers for Rails 3.1+ asset pipeline compatibility:
  include Sprockets::Helpers::RailsHelper
  include Sprockets::Helpers::IsolatedHelper

  # Choose what kind of storage to use for this uploader:
  # storage :file
  storage :fog

  # Set the mimetype of the upload incase it is incorrect.
  include CarrierWave::MimeTypes
  process :set_content_type

  process :resize_to_limit => [640, 640]

  version :thumb do
    process :resize_to_fill => [160, 120]
  end

end

記事モデル

class Article < ActiveRecord::Base
  attr_accessible :orientation, :shoot_id, :image
  belongs_to :shoot
  mount_uploader :image, ImageUploader

  after_save :enqueue_image

  def image_name
    File.basename(image.path || image.filename) if image
  end

  def enqueue_image
    ImageWorker.perform_async(id, key) if key.present?
  end

  class ImageWorker
    include Sidekiq::Worker

    def perform(id, key)
        article = Article.find(id)
        article.key = key
        article.remote_image_url = article.image.direct_fog_url(:with_path => true)
        article.save!
        article.update_column(:image_processed, true)
    end

  end

end
