从 Rails 3 升级到 Rails 4 后 CarrierWave url nil

Question

在将我们的应用程序从 Rails 3.2.22 升级到 Rails 4.2.11 时，升级前可用的几种 CarrierWave 方法现在 return 为零，例如 .url 和 .file。我们在 AWS S3 上托管我们的资产，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 3.2.22

Ruby 2.2.5

fog-aws 3.3.0

到目前为止，我已尝试更改载波配置，并在 rails 控制台中尝试不同的方法，并将开发结果与生产结果进行比较。

Gemfile

source 'https://rubygems.org'
ruby '2.2.5'

gem 'rails', '4.2.11'

gem 'pg', '0.15.1'

end

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 return 来自 S3 的资产路径 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"

但是在生产中 art.url => nil。

当我在开发控制台中输入 art 时，它 return 是这个对象：

=> #<ArtUploader::Uploader70128841541160:0x007f904c7c88f8
 @cache_id=nil,

   @cache_called=nil,
   @uploader=#<ArtUploader::Uploader70128841541160:0x007f904c7c88f8 ...>>,
 @versions={}>

当我在生产中输入相同的内容时 returns:

#<ArtUploader::Uploader6168740:0x000000072781c8 @model=#<Album id: 2008, title: "Vektlaus", art: "Daniel+Kvammen+-+Vektlaus.jpg", state: "active", description: nil, created_at: "2017-05-19 18:40:43", updated_at: "2017-07-26 16:51:17">, @mounted_as=:art, @file=nil, @filename=nil, @cache_id=nil, @versions={}, @format=nil, @parent_version=#<ArtUploader:0x00000007278d30 @model=#<Album id: 2008, title: "Vektlaus", art: "Daniel+Kvammen+-+Vektlaus.jpg", state: "active", description: nil, created_at: "2017-05-19 18:40:43", updated_at: "2017-07-26 16:51:17">, @mounted_as=:art, @file=nil, @filename=nil, @cache_id=nil, @versions={:thumbnail=>#<ArtUploader::Uploader6168740:0x000000072781c8 ...>}, @format=nil, @storage=#<CarrierWave::Storage::Fog:0x000000072786f0 @uploader=#<ArtUploader:0x00000007278d30 ...>>>, @storage=#<CarrierWave::Storage::Fog:0x00000007267300 @uploader=#<ArtUploader::Uploader6168740:0x000000072781c8 ...>>>

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。
