无法在Rails中连接到AWS？我该怎么做才能调试？

我已经在轨道中实现了回形针,正如各种教程所推荐的那样.在尝试上传照片时,我始终如一地获得以下内容:

AWS::S3::NoConnectionEstablished

这是我的模型声明:

attr_accessor :image_file_name
  has_attached_file :image, 
    :styles => { :medium => "300x300>", :thumb => "100x100>" },
    :storage => :s3,
    :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
    :s3_headers => {"Expires" => 1.year.from_now.httpdate},
    :path => ":attachment/:id/:style/:basename.:extension",
    :bucket => "something_unique"

这是我的s3.yml的格式:

development:   
  access_key_id: "my_key" 
  secret_access_key: "my_secret_key" 
production:   
  access_key_id: "my_key"  
  secret_access_key: "my_secret_key"

有什么想法发生了什么？

谢谢!

为了帮助调试,请尝试将paperclip从等式中取出并直接从Ruby访问Amazon S3.您可以使用s3sh打开IRB 的命令并加载aws-s3 gem 来执行此操作.s3sh在命令行中运行并尝试键入以下内容.

# connect to S3 using your credentials
AWS::S3::Base.establish_connection!(
  :access_key_id     => 'my_key',
  :secret_access_key => 'my_secret_key'
)

# Store an image on S3
S3Object.store("foo.jpg", open("path/to/foo.jpg"), "something_unique")

# See if it's on there
bucket = Bucket.find("something_unique")
bucket["foo.jpg"]

您可以在此处找到有关aws-s3 gem的更多信息.
