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？
