Where to get the value of region and what is it? Give an example what is a region!

[thebravoman]

With this version the region is required.

If I use us-west-2a I get

[Aws::S3::Client 0 2.243104 3 retries] put_object(content_type:"image/png",acl:"public-read",bucket:"fllcasts-development",key:"schools/pictures/000/000/027/original/exit_rbp_exit.png",body:#<File:/tmp/023b288fd692b5b3b3fa532314682be420160719-28827-1ul6wyq.png (102088 bytes)>) Seahorse::Client::NetworkingError getaddrinfo: Name or service not known

If i use us-west-2 I get

Try the code we include with the Aws.partition method, http://docs.aws.amazon.com/sdkforruby/api/Aws.html#partition-class_method.

Aws.partition('aws').regions.map(&:name)

It just returned:

us-east-1
us-west-1
us-west-2
ap-northeast-1
ap-northeast-2
ap-south-1
ap-southeast-1
ap-southeast-2
sa-east-1
eu-west-1
eu-central-1

You're seeing two different errors here.

1. us-west-2a is not a valid region identifier.
2. us-west-2 is a valid region, but if you're getting a Aws::S3::Errors::AccessDenied exception back from the service, it means you do not have permissions to perform that #put_object request. You should check the IAM role that you're using for your client to ensure it actually has permissions to make S3 calls and that it has permissions to write to that bucket.

I've submitted a pull-request that wraps the socket error you received above with a helpful error that indicates the likely cause and what possible regions are.
