¿No puede conectarse a AWS en Rails? ¿Qué debo hacer para depurar?

Question

He implementado paperclip en rails exactamente como recomiendan una variedad de tutoriales. Al intentar subir una foto, recibo constantemente lo siguiente:

AWS::S3::NoConnectionEstablished

aquí está mi declaración de modelo:

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"

Aquí está el formato de mi s3.yml:

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

¿Alguna idea de lo que está pasando?

¡Gracias!

Para ayudar a depurar, intente sacar un clip de la ecuación y acceder a Amazon S3 directamente desde Ruby. Puede hacerlo utilizando el comando s3sh que abre IRB y carga la gema aws-s3. Ejecute s3sh en su línea de comando e intente escribir lo siguiente.

# 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"]

Puede encontrar más información sobre la gema aws-s3 aquí .
