You can’t really sort a regular hash—by definition a hash is unordered. So what output do you want? Possibly an array structured (I’m not showing it sorted) something like: [[4049,[4133,100]],[5814,[4075,84]]…]. Rails provides a kind of hybrid thing, OrderedHash, which you could build—but you’d have to build an array and then sort it anyway in order to be able to insert items into an OrderedHash in sort order. -- Scott Ribe [email protected] http://www.elevated-dev.com/ https://www.linkedin.com/in/scottribe/ (303) 722-0567 voice -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
