Like you care…
xml = generate_xml
require 'xml'
Tempfile.open(self.class.to_s) do |tmp|
tmp.write(xml)
tmp.close
document = XML::Document.file(tmp.path)
schema_doc = XML::Document.file("some.xsd")
schema = XML::Schema.document(schema_doc)
assert document.validate(schema), "the xml isn't valid. look above for error."
end
Has the right idea about how to store files, but the lib it uses does not abstract things enough. Does not use http keep alive to avoid the slow startup of tcp. Does not have an easy way to iterate over all keys in a bucket, but this helps to do this:
def each_object(bucket_name)
next_marker = nil
while true do
response = CONN.list_bucket(bucket_name, {'marker' => next_marker, 'max-keys' => 10})
response.entries.each do |s3obj|
yield s3obj
end
break unless response.properties.is_truncated
next_marker = response.entries.last.key
end
end
Again no built in way to iterate over all keys. Has problems with ‘/’ at the start of file names.
Uses the same http connection, can iterate over all keys with a single method (though, it makes a full array of all the keys rather than allowing you to supply a block). Here’s my thumbnailer:
require 'rubygems'
require 'right_aws'
require 'RMagick'
require 'pp'
s3 = RightAws::S3.new(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
picture_bucket = s3.bucket('OurPictures')
thumbnail_bucket = s3.bucket('OurPicturesThumbnails')
picture_bucket.keys.each do |key|
thumbnail_key = RightAws::S3::Key.create(thumbnail_bucket, key.name)
next if key.name !~ /.jpg$/i
next if thumbnail_key.exists?
image = Magick::Image.from_blob(key.data).first
image.change_geometry!('256x256>') do |cols, rows, img|
img.thumbnail!(cols, rows)
end
thumbnail_key.put(image.to_blob, 'private')
p thumbnail_key.full_name
image = nil
GC.start
end
(mostly randy here again. I was putting up my first ec2 instance. :)
