使用“ aws-sdk”保存后如何重命名S3存储桶上的文件？

Question

I'm trying to update a file name saved on aws s3 using below code

gem 'aws-sdk', '~> 2.3'

creds = Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'])

s3 = Aws::S3::Resource.new(credentials: creds, region: ENV['AWS_REGION'])

bucket = s3.bucket(ENV['AWS_S3_BUCKET'])

filename = URI.unescape(document.url).split('/').last

new_file = 'new_file_name'

obj = bucket.object(filename) # create object of original file name

obj.move_to("#{bucket.name}/#{new_file}", acl: 'public-read')

obj = bucket.object(new_file)

when updating giving an error on line obj.move_to("#{bucket.name}/#{new_file}", acl: 'public-read') :

Aws::S3::Errors::NoSuchKey 
The specified key does not exist.

Any suggestions or ideas how to rename a file on s3?

object.inspect output:

Thanks

You are trying to move an object with key x to key nil . Given your error I would try initializing a new object y first then call the move_to on it.
