ruby-on-rails-3 - 由于某种原因未创建 Rails CarrierWave 版本

Question

我有以下文件 uploader

class ItemImageUploader < CarrierWave::Uploader::Base
  include ::CarrierWave::Backgrounder::Delay
  include CarrierWave::MiniMagick
  include Sprockets::Helpers::RailsHelper
  include Sprockets::Helpers::IsolatedHelper

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  def default_url
    asset_path("fallback/" + [version_name, "image.png"].compact.join('_'))
  end

  def cache_dir
      "uploads/tmp"
  end

  # Create different versions of your uploaded files:
  version :thumb do
    process :resize_to_fill => [80,80]
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end

图片类

class Picture < ActiveRecord::Base
  belongs_to :imageable, :polymorphic => true
  mount_uploader :image, ItemImageUploader
  process_in_background :image
  validates_presence_of :image

  def copy
    Picture.new(:image => self.image)
  end

在 Carrier_wave.rb 初始化文件中进行以下配置:

CarrierWave.configure do |config|
config.enable_processing = true
    #config.permissions = 0666
    #config.directory_permissions = 0777
    config.storage = :file
end

图像上传正确，但未创建缩略图，未发生错误。请指教。

我自己就用头撞了这个。正如评论所暗示的，使用 rierwave_backgrounder 会导致此问题。你可以在他们的 documentation 中看到它:

process_in_background - 这存储没有处理/版本控制的原始文件。

对解决问题没有帮助，但我想我应该验证一下问题。
