Ruby on rails 3 Carrierwave直接上传到s3，sidekiq验证失败

遵循Ryan Bates教程，使用CarrierWave和Sidekiq的后台作业直接上传到S3

我在sidekiq日志的后台工作程序中看到以下错误

    2012-11-10T14:33:56Z 44401 TID-owd2xrzdg WARN: {"retry"=>true, "queue"=>"default", "class"=>"Article::ImageWorker", "args"=>[44, "uploads/d8850e90-0d6d-0130-fecf-3c0754129341/mkv5E.jpg"], "jid"=>"8add5079541725ad30550f9c", "error_message"=>"Validation failed: Image could not download file", "error_class"=>"ActiveRecord::RecordInvalid", "failed_at"=>"2012-11-10T14:29:15Z", "retry_count"=>4, "retried_at"=>2012-11-10 14:33:56 UTC}

这是我的上传器

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

快照控制器显示负责呈现上载表单的操作

  # GET /shoots/1
  # GET /shoots/1.json
  def show
    # TODO: is this the best way to prevent users from accessing not owned resources.
    @shoot = Shoot.find(params[:id])
    @uploader = Article.new.image
    @uploader.success_action_redirect = new_admin_article_url    
    if @shoot
      respond_to do |format|
        format.html # show.html.erb
      end
    else
      redirect_to shoots_path, alert: 'No shoot found with id: #{params[:id]}'
    end
  end

显示动作上传器的表单

<div class="hero-unit">
  <h2><%= @shoot.name %></h2>
  <p><%= @shoot.overview %></p>
  <p>This shoot was taken on <%= @shoot.shoot_date %></p>
  <%= direct_upload_form_for @uploader do |f| %>
    <p><%= f.file_field :image, multiple: true, name: "article[image]" %></p>
    <p><%= f.submit "Add Media", :class => "btn btn-primary" %></p>
  <% end %>
</div><!-- /hero-unit -->

这张照片是拍的


“btn btn主要”%>

结果是我的bucket名称无效。。。确保您的bucket名称仅包含字母、数字和破折号。

此外，您不需要说storage:fog--CarrierWave Direct默认情况下会这样做。

  # GET /shoots/1
  # GET /shoots/1.json
  def show
    # TODO: is this the best way to prevent users from accessing not owned resources.
    @shoot = Shoot.find(params[:id])
    @uploader = Article.new.image
    @uploader.success_action_redirect = new_admin_article_url    
    if @shoot
      respond_to do |format|
        format.html # show.html.erb
      end
    else
      redirect_to shoots_path, alert: 'No shoot found with id: #{params[:id]}'
    end
  end

<div class="hero-unit">
  <h2><%= @shoot.name %></h2>
  <p><%= @shoot.overview %></p>
  <p>This shoot was taken on <%= @shoot.shoot_date %></p>
  <%= direct_upload_form_for @uploader do |f| %>
    <p><%= f.file_field :image, multiple: true, name: "article[image]" %></p>
    <p><%= f.submit "Add Media", :class => "btn btn-primary" %></p>
  <% end %>
</div><!-- /hero-unit -->
