How to convert a ruby hash object to JSON?
...thod `to_json' for {:make=>"bmw", :year=>"2003"}:Hash
# from (irb):11
# from /usr/bin/irb:12:in `<main>'
require 'json'
# => true
car.to_json
# => "{"make":"bmw","year":"2003"}"
As you can see, requiring json has magically brought method to_json to our Hash.
