Mes fichiers se présentent comme suit:

1) app/modèles/image.rb

class Image < ActiveRecord::Base
has_and_belongs_to_many :pairs
validates_presence_of :img_file_name
has_attached_file :img, :styles => {:thumb=> "100x100#", :page => "400x320>"}, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml"
end

2) config/s3.yml

bucket: (MY BUCKET HERE)
access_key_id: (MY ACCESS KEY ID HERE)
secret_access_key: (MY SECRET ACCESS KEY HERE)

Comment puis-je le faire fonctionner?

Answer 1

C: /Ruby/lib/ruby/1.8/yaml.rb: 133: dans load '- il s'agit d'une erreur YAML. Vous avez probablement un fichier YML mal formaté. Essayez ce code dans votre script/console:

require 'yaml' 
my_hash = YAML::load File.read("#{RAILS_ROOT}/config/s3.yml") 

est Ci-dessous un exemple de ma config de travail:

has_attached_file :data, 
    :styles => { 
    :small => "100x100#", 
    :medium => "400x400#", 
    :large => "640x480#" 
    }, 
    :storage => :s3, 
    :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", 
    :path => ":attachment/:id/:style.:extension", 
    :bucket => "xxx" 

Et le fichier YML:

development: 
    access_key_id: *** 
    secret_access_key: *** 

Answer 2

Vous aviez raison. Mon éditeur de texte 'e' enregistrait le fichier yaml dans un format étrange avec quelques caractères supplémentaires. Tout fonctionne en ce moment. MERCI!
