Paperclip save to disk and s3

Rails
1

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.


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

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.
