Carrierwave / Fog - 参数错误,提供程序无法识别

我正在使用Carrierwave 0.5.3和Fog将图像上传到Amazon-S3。

在本地运行时,设置顺利运行,没有错误。

但是当在Heroku上运行时,上传失败并显示以下消息:

2011-03-31T12:53:46-07:00 app[web.1]: ArgumentError ( is not a recognized storage provider):
2011-03-31T12:53:46-07:00 app[web.1]:   app/controllers/useditems_controller.rb:36:in `create'

我有一个初始化程序:

# /config/initializers/fog.rb
CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => 'secret',
    :aws_secret_access_key  => 'also secret',
    :region                 => 'eu-west-1'
  }
  config.fog_directory  = 'jabberwocky'
end

还有一个上传者:

# /app/uploaders/image_uploader.rb
# encoding: utf-8

class ImageUploader < CarrierWave::Uploader::Base

  # Include RMagick or ImageScience support:
  include CarrierWave::RMagick

  # Choose what kind of storage to use for this uploader:
  storage :fog

  # 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
    "useditems"
  end

  def cache_dir
    "#{Rails.root}/tmp/uploads"
  end

  # Create different versions of your uploaded files:
  version :thumb do
     process :resize_to_limit => [220, 2000]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_white_list
    %w(jpg jpeg gif png)
  end

end

我已将错误消息跟踪到Fog,似乎在Heroku下的Fog没有从初始化程序获取配置信息。 :provider某种程度上是空的。但我对如何修复它感到困惑。

非常感谢任何帮助。

我正在使用:

rails 3.0.4
heroku 1.19.1
fog 0.7.1
ruby 1.9.2 under rvm

2 个答案:

答案 0 :(得分:2)

错误是由于我错误地将初始化程序添加到.gitignore文件中。因此,它从未上传到Heroku。

答案 1 :(得分:2)

添加此内容以获得完整性......

使用此错误消息将我的头撞到墙上数小时后,我发现我在carrierwave初始化器的开头有这条线:

if Rails.env.test?
  ...

因此初始化程序仅在测试环境中考虑。删除后,一切都按预期工作。
