2. You could write
x = Klass.find(key)
if x.nil?
x = Klass.new
x.save
end
get_or_new doesn't save, so perhaps Klass.find(key) || Klass.new(key)
Risky (another Ruby Riak model layer) offers Klass.get_or_new(key)
3. control the bucket on which the document is stored/retrieve
(using an attribute). From what I've seen, riak uses the class name
as bucket.
I don't know about Ripple, but in Risky you could:
a.) Override MyModel.bucket to choose different buckets.
b.) Subclass and set MyModel.bucket
c.) Ignore/override MyModel.[] altogether, fetch the robject yourself,
and use Klass.from_riak_object.
You should be aware that buckets are essentially key prefixes. When you
go to *get* a record, you would need to know the bucket name. Two cases:
Lots of buckets, e.g. one per user: Why not make the username part of
the key? It may not feel as clean, but you won't have to fight the ORM
as much.
Few buckets, e.g. Record, RecordTypeA < Record, RecordTypeB < Record:
Subclass and set/override .bucket.
