S3 library provides access to Amazon’s Simple Storage Service.
It supports all S3 regions through the REST API.
gem install s3
require "s3"
service = S3::Service.new(:access_key_id => "...",
:secret_access_key => "...",
:host => “127.0.0.1”)
#=> #<S3::Service:...>
service.buckets #=> [#<S3::Bucket:first-bucket>, # #<S3::Bucket:second-bucket>]
first_bucket = service.buckets.find("first-bucket") #=> #<S3::Bucket:first-bucket>
new_bucket = service.buckets.build("newbucketname") new_bucket.save(:location => :eu)
Remember that bucket name for EU can’t include “_” (underscore).
Please refer to: docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html for more information about bucket name restrictions.
first_bucket.objects #=> [#<S3::Object:/first-bucket/lenna.png>, # #<S3::Object:/first-bucket/lenna_mini.png>]
object = first_bucket.objects.find("lenna.png") #=> #<S3::Object:/first-bucket/lenna.png>
object.content_type #=> "image/png"
object.content #=> "\x89PNG\r\n\x1A\n\x00\x00\x00\rIHDR\x00..."
object.destroy #=> true
new_object = bucket.objects.build("bender.png") #=> #<S3::Object:/synergy-staging/bender.png> new_object.content = open("bender.png") new_object.save #=> true
Please note that new objects are created with “private” ACL by default.
object = bucket.objects.find('lenna.png') object.request_acl # or bucket.request_acl
This will return hash with all users/groups and theirs permissions
object = bucket.objects.find("lenna.png") object.copy(:key => "lenna.png", :bucket => bucket, :acl => :public_read)
Check the example in this gist, which describes how to use a simple form element to upload files directly to S3.
