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

I am trying to upload image at aws.

class Asset < ActiveRecord::Base
  belongs_to :post
  attr_accessible :image
  has_attached_file :image, :styles => { :medium => "640x480>", 
                                     :thumb => "100x100#"},
  :storage => :s3,
   :s3_credentials => "#{Rails.root}/config/s3.yml",
  :path => ":attachment/:id/:style.:extension",
  :bucket => 'yourbucket'
end

s3.yml 

development:
  access_key_id: xxxxxxxx

   secret_code: xxxxx

I am getting a message 

 AWS::Errors::MissingCredentialsError in PostsController#create

Missing Credentials.

 Unable to find AWS credentials.  You can configure your AWS credentials
 a few different ways:

 * Call AWS.config with :access_key_id and :secret_access_key

 * Export AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to ENV

* On EC2 you can run instances with an IAM instance profile and credentials 
 will be auto loaded from the instance metadata service on those
  instances.

* Call AWS.config with :credential_provider.  A credential provider should
either include AWS::Core::CredentialProviders::Provider or respond to
the same public methods.

= Ruby on Rails

In a Ruby on Rails application you may also specify your credentials in the following ways:

I believe I am doing the last step.

Gemfile 

gem 'rails', '3.1.3'
gem 'mysql'
gem 'koala'
gem 'paperclip'
gem 'aws-s3'
gem 'aws-sdk'

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>"
