Rename Object in S3 using Ruby

问题:

I want to rename an item in s3 using the Ruby sdk. How do I do this?

I have tried:

require 'aws-sdk'
s3 = AWS.config(
        :region => 'region',
        :access_key_id => 'key',
        :secret_access_key => 'key'
)

b = AWS::S3::Bucket.new(client: s3, name: 'taxalli')


    b.objects.each do |obj|
       obj.rename_to('imports/files/' + line.split(' ').last.split('/').last)
      end

But I dont see anything in the new sdk for moves or renames.

There is no such thing as renaming in the Amazon S3 SDK. Basically what you have to do is copy the object and then delete the old one.

    require 'aws-sdk'
    require 'open-uri'


    creds = Aws::SharedCredentials.new(profile_name: 'my_profile')

    s3 = Aws::S3::Client.new( region: 'us-east-1',
                              credentials: creds)



    s3.copy_object(bucket: "my_bucket",
                   copy_source: URI::encode("my_bucket/MyBookName.pdf"),
                   key: "my_new_book_name.pdf")

    s3.delete_object(bucket: "my_bucket",
                     key: "MyBookName.pdf")

In AWS-SDK version 2 is now method called "move_to" (http://docs.aws.amazon.com/sdkforruby/api/Aws/S3/Object.html#move_to-instance_method) which you can use in this case. Technically it will still copy & delete that file on S3 but you don't need to copy & delete it manually and most importantly it will not delete that file if that copy action fails from some reason.

have you Rails Paperclip S3 rename thousands of files? or https://gist.github.com/ericskiff/769191 ?
