The #<blah key1: value1, key2: value2 ...> comes from YAML. There's no way to pull out all the keys? I know if the yaml file doesn't contains - !ruby/object:RmEnv, YAML.load will create a hash #<key1: value1, key2: value2 ...> which I can loop through with each_key. If it's a ruby object, I'm out of luck? The data is just a database dump of a Rail Model RmEnv where keys are the db field and the values their values. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
