Question

I have this ruby object

options = [
  {"ActionScript"=>"orange"},
  {"AppleScript"=>"orange"},
  {"Asp"=>"red"},
  {"BASIC"=>"green"},
  {"C"=>"blue"},
  {"C++"=>"purple"},
  {"Clojure"=>"green"},
  {"COBOL"=>"red"},
  {"ColdFusion"=>"red"},
  {"Erlang"=>"green"},
  {"Fortran"=>"orange"},
  {"Groovy"=>"green"},
  {"Haskell"=>"green"},
  {"Java"=>"green"},
  {"JavaScript"=>"brown"},
  {"Lisp"=>"purple"},
  {"Perl"=>"blue"},
  {"PHP"=>"red"},
  {"Python"=>"green"},
  {"Ruby"=>"green"},
  {"Scala"=>"green"},
  {"Scheme"=>"orange"}
]

and i’d like it to be mapped to this:

[{"name":"ActionScript","value":"orange"},{"name":"AppleScript","value":"orange"}...]

Thanks in advance.

require 'json'

options.map {|elem| elem.map {|k,v| {:name => k, :value => v}}}.flatten.to_json
