How to iterate over each members of an object in ruby on rails

Question

i have an object from a third party REST API. What I want to do is to iterate over each members of the object and get its key and value. The format of the object is like this :

 { 1st:"1", 2nd: "2", 3rd: "3rd" }

it's as simple as

hash = { ... } # result from api call

hash.each do |key, value|
  # do your thing here
end

BTW, in ruby it's called "a hash", not "an object".

is the OP's hash valid? – Sagar Pandya Nov 20 '16 at 15:57
good point @sagarpandya82 - am assuming that's just an example and the keys don't actually begin numbers? – mikej Nov 20 '16 at 15:59
Thanks it works :) – markpenaranda Nov 20 '16 at 16:01
