From: Mage Date: 2006-08-14T07:22:20+09:00 Subject: hash.keys and hash.values Hello, I know the order of the keys of a hash is arbitary. However, has the hash.keys and hash.values same order? Will they be consistent with each other? I found nothing in the manual about this. The @Agile Web Developing" book uses the form below: Users.update(params[:user].keys,params[:user].values) So, I think, the order of the keys and values should be same. If it is then it should be documented, too. If I missed something, excuse me. Mage
