ruby-on-rails-4 - 从 Rails 3 升级到 Rails 4 后，CarrierWave url 为零

Question

在将我们的应用程序从 Rails 3.2.22 升级到 Rails 4.2.11 时，升级之前工作的几个 CarrierWave 方法现在返回 nil，例如 .url和 .file .我们将 Assets 托管在 AWS S3 上，我们的应用程序托管在 Heroku 上。奇怪的是，图像在我们的开发环境中按预期工作。
CarrierWave 1.3.1 (upgraded from 0.11.2)Rails 4.2.11, upgraded from 3.2.22Ruby 2.2.5fog-aws 3.3.0
到目前为止，我已经尝试改变了载波配置，并在 rails 控制台中尝试了不同的方法，并将开发和生产中的结果进行了比较。

carrierwave.rb


CarrierWave.configure do |config|
  config.fog_provider = 'fog/aws'
  config.fog_credentials = {
      provider: ENV['FOG_PROVIDER'],
      aws_access_key_id: ENV['AWS_ACCESS_KEY_ID'],
      aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
      region: ENV['FOG_REGION'],
      endpoint: ENV['FOG_HOST']
    }
  if Rails.env.production?
    config.storage = :fog
    config.fog_directory = ENV['FOG_DIRECTORY']
    config.fog_public = false
    config.fog_authenticated_url_expiration = 1800
  else
    config.asset_host = "#{ENV['FOG_HOST']}"
    config.storage = :file
    config.enable_processing = false if Rails.env.test?
  end
end

art_uploader.rb

# encoding: utf-8

class ArtUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick

  version :thumbnail do
    process resize_to_fill: [100, 100]
  end

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Add a white list of extensions which are allowed to be uploaded.
  def extension_white_list
    %w(jpg jpeg png)
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  def default_url
    if model.has_fallback_art?
      version_name == :thumbnail  
      model.song.artist.photo.small_thumb.url : 
      model.song.artist.photo.album_art.url
    end
  end

end

我希望在进入时能够从 S3 返回 Assets 路径 art.url
在开发中我得到 art.url => "https://qa-marmosetmusic-com.s3.amazonaws.com/uploads/artist/photo/173/af2ac015-1d44-4481-b5d6-5bf5cb8c0e23.jpg"
然而在生产中 art.url => nil .

当我输入 art在开发控制台中，它返回这个对象:

   @cache_called=nil,

当我在生产中输入相同的内容时，它会返回:

我很想听听任何建议。
谢谢!

我们解决了这个问题!

我们在carrierwave/storage中有一个名为fog.rb的文件，它覆盖了gem行为并导致了这个问题。删除该文件允许一切按预期工作。
