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
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。

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。
