AWS::Errors::MissingCredentialsError using paperclip and aws-s3 in rails 3.1

Question

I am trying to upload image at aws.

class Asset < ActiveRecord::Base
  belongs_to :post
  attr_accessible :image
  has_attached_file :image, :styles =>         


        

Answer 1

The following worked for me:

1. Create a file in your initializers called aws.rb

2. Put in the following in your aws.rb file:

   AWS.config(
   access_key_id: 'your_access_key',
   secret_access_key: 'your_secret_access_key')
   

3. Then my paperclip options looks like this:

   has_attached_file :photo, :styles => { :medium => "300x300>", :thumb => "100x100>" },       
   :default_url => "missing_:style.png", :default_url => 'missing_:style.png', :storage =>   
   :s3, :bucket => "<my_bucket>"
