Feature Suggestion: `Ohm::Model::fetch` for uniques?

Hi all,
I was curious if anyone thought a method that fetches records by a unique and an array of values would be useful on Ohm::Model? It would look something like...
# I'm not a fan of the method name...
def self.fetch_with(att, values)
raise Ohm::IndexNotFound unless uniques.include?(att)
ids = nil
unique = key[:uniques][att]
synchronize do
values.map { |value| redis.queue('HGET', unique, value) }
ids = redis.commit
end
return [] if ids.nil?
fetch(ids)
end
There is a point in the application I'm working on that uses something similar, and just wanted to share incase you all might find a generic version of it it useful for everyone.
I love the comment about not being a fan :-)
I think this is interesting. Are you still using it?
There is a couple of points I am using something very similar to what I wrote above. Basically the app has some light social features and an example where it can be useful is to look up a collection of users via unique nicknames instead of id.
