Lately, I’ve been using right_aws to interact with S3. One thing that I found helpful was copying assets between buckets and keeping the same permissions on them. However, it’s not as simple as just copying the assets over. You need to get the Access Control Policy from the source and put it in the copied asset.

Here’s a snippet of code that does the magic.


require 'rubygems'
require 'right_aws'

s3=RightAws::S3Interface.new(S3_KEY, S3_SECRET)
s3.copy(SOURCE_BUCKET, SOURCE_PATH, DESTINATION_BUCKET, DESTINATION_PATH, :copy, {"Cache-Control" => 'max-age=315360000', "Expires" => '315360000'})
acl_prop=s3.get_acl(SOURCE_BUCKET, SOURCE_PATH)
s3.put_acl(DESTINATION_BUCKET, DESTINATION, acl_prop[:object])
