Rails CarrierWave版本不是出于某种原因而创建的 [英] Rails CarrierWave versions are not created for some reason

问题描述

我有以下文件上传器

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

以及car_wave.rb初始化文件中的以下配置：

And the following config in carrier_wave.rb initialization file:

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

图片已正确上传，但未创建缩略图，未发生任何错误。请指教。

Images uploaded properly, but no thumbnails created, no errors occurred. Please advise.

推荐答案

我自己就碰到了这个。正如评论所示，使用 carrierwave_backgrounder 会导致此问题。您可以在文档中看到它：

Just hit my head against this one myself. As the comments suggest, using carrierwave_backgrounder causes this problem. You can see it in their documentation:

process_in_background - 这会保存原始文件而不进行处理/版本控制。

process_in_background - This stores the original file with no processing/versioning.

无效解决方案，但我想我会验证问题。

Doesn't help with a solution, but I thought I'd verify the problem.
