ruby-on-rails - 从早期版本升级到 3.x(S3 存储)后，回形针不生成缩略图/样式/大小

Question

我在创建图像时为 Paperclip gem 定义的各种 :styles 在升级后停止工作。这些文件根本没有创建，但“原始”是(唯一的)。

class Image < ActiveRecord::Base
  belongs_to  :member
  has_many    :article_images, :dependent => :destroy
  has_many    :articles, :through => :article_images

  has_many    :member_photos, :dependent => :destroy
  has_one     :member_avatar, :dependent => :destroy

  validates_presence_of :member_id

  after_validation do |resource| 
    #since paperclip doesn't give a damn error message like an idiot
    resource.errors[:image] = resource.errors[:image_file_name] ?  resource.errors[:image_file_name] : resource.errors[:image_content_type]
  end

  before_save do |resource| 
    #set name to filename if no name sent
    resource.name = resource.image_file_name.split('.')[0].titleize if resource.name.blank? 
  end

  scope :for_slideshow, limit(5) 

  has_attached_file :image, 
    :styles => { 
      :original    => "1100x1100", #overwrites orig, for file storage efficiency
      :x_large     => "900x900",
      :large       => "600x600",
      :medium      => "300x300>",
      :thumb_1     => "100x100#",
      :thumb_2     => "50x50#",
      :thumb_3     => "25x25#"
      #To refresh image thumbs: rake paperclip:refresh CLASS=Image
    },
    :storage => :s3,
    :path => ":attachment/:id/:style.:extension",
    :s3_credentials => "#{::Rails.root}/config/s3.yml"

    #:url => "/system/:attachment/:id/:style/:filename"


  validates_attachment_content_type :image, :content_type=>['image/jpeg', 'image/png', 'image/gif', 'image/pjpeg', 'image/x-png'] #last two for IE 6-8
  validates_attachment_presence :image
  #validates_attachment_size :image, :less_than=>1.megabyte

end

日志不再显示任何尝试:

我错过了什么？

无论出于何种原因，降级到 2.8 已经“修复”了这个问题。但我想使用最新版本...
