Answer 1

This will work using the aws-sdk-s3 gem

aws_client = Aws::S3::Client.new(
  region:               'us-west-2', #or any other region
  access_key_id:        AWS_ACCESS_KEY_ID,
  secret_access_key:    AWS_SECRET_ACCESS_KEY
)


s3 = Aws::S3::Resource.new(client: aws_client)
bucket = s3.bucket('bucket-name')
obj = bucket.object("${filename}-#{SecureRandom.uuid}")

url = obj.presigned_url(:put)

additional http verbs:

obj.presigned_url(:put)                              
obj.presigned_url(:head)                    
obj.presigned_url(:delete)
