Rails - Aug 2010 - paperclip save to disk and s3

I have a standard Paperclip setup that saves a file to my disk.  In
addition I would also like the file saved to my amazon s3 bucket.

[code]

after_save :copy_to_s3



  def copy_to_s3
   has_attached_file :photo,
   :storage => :s3,
   :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
   :styles => {
   :thumb => "100x100#",
   :small => "750x750>" }
  end

[/code]


This is giving the error: undefined method `has_attached_file''

Because it''s in another scope of object
And it''s nothing give to u, it''s one define some methods

U can open paperclip source and find out how call upload to s3, or u can use
aws-s3 gem, which simple, s3 is http based storage, simple http query, and all a
done ))

Scratch the idea then.

So I found this gem called db2s3 which is used to backup the database 
with a simple rake command.  I having trouble modifying it accordingly.


require ''activesupport''
require ''aws/s3''
require ''tempfile''

class BLUECAT
  class Config
  end

  def initialize
  end

  def full_backup

    file_name =
"system-#{Time.now.utc.strftime("%Y%m%d%H%M")}.gz"


    store.store(file_name, open(backup_directory.path))
    store.store(most_recent_dump_file_name, file_name)

  end

 private



  def backup_directory
     backup_file = Tempfile.new("dump")

     cmd = "cp -r #{RAILS_ROOT}/public/system/ bucket"
     cmd += " | gzip > #{backup_file.path}"
     run(cmd)

     backup_file
  end



  def store
    @store ||= S3Store.new
  end



  def most_recent_dump_file_name
   "most-recent-dump.txt"
  end

  def run(command)
    result = system(command)
    raise("error, process exited with status #{$?.exitstatus}") unless
result
  end

  def db_credentials
    ActiveRecord::Base.connection.instance_eval { @config } # Dodgy!
  end

  class S3Store
    def initialize
      @connected = false
    end

    def ensure_connected
      return if @connected
     
AWS::S3::Base.establish_connection!(BLUECAT::Config::S3.slice(:access_key_id,
:secret_access_key).merge(:use_ssl => true))
      AWS::S3::Bucket.create(bucket)
      @connected = true
    end

    def store(file_name, file)
      ensure_connected
      AWS::S3::S3Object.store(file_name, file, bucket)
    end

    def fetch(file_name)
      ensure_connected
      AWS::S3::S3Object.find(file_name, bucket)

      file = Tempfile.new("dump")
      open(file.path, ''w'') do |f|
        AWS::S3::S3Object.stream(file_name, bucket) do |chunk|
          f.write chunk
        end
      end
      file
    end

    def list
      ensure_connected
      AWS::S3::Bucket.find(bucket).objects.collect {|x| x.path }
    end

    def delete(file_name)
      if object = AWS::S3::S3Object.find(file_name, bucket)
        object.delete
      end
    end

    private

    def bucket
      BLUECAT::Config::S3[:bucket]
    end
  end

end


In the backup_directory method, I can''t figure out how to get it to
copy
the system directory into my s3 bucket.
