从Rails 3升级到Rails 4后，CarrierWave网址为零

Question

在将我们的应用程序从Rails 3.2.22升级到Rails 4.2.11时，在升级之前工作的几个CarrierWave方法现在返回nil，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，我已尝试更改了carrierwave配置，并在rails控制台中使用不同的方法，并将开发中的结果与生产进行比较。

Gemfile

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

group :development do

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

当我输入art.url时，我希望能够从S3返回资产路径

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qazxsw poi。

当我在开发控制台中输入art.url => nil时，它返回以下对象：

art

当我在生产中输入相同的内容时，它返回：

我很乐意听到任何建议。谢谢！

Answer 1

我们解决了这个！

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。
