How do I parse JSON with Ruby on Rails? [duplicate]

Question

I'm looking for a simple way to parse JSON, extract a value and write it into a database in Rails.

Specifically what I'm looking for, is a way to extract shortUrl from the JSON returned from the bit.ly API:

{   "errorCode": 0,   "errorMessage": "",   "results":   {     "http://www.foo.com":     {        "hash": "e5TEd",        "shortKeywordUrl": "",        "shortUrl": "http://bit.ly/1a0p8G",        "userHash": "1a0p8G"     }   },   "statusCode": "OK" } 

And then take that shortUrl and write it into an ActiveRecord object associated with the long URL.

This is one of those things that I can think through entirely in concept and when I sit down to execute I realize I've got a lot to learn.

These answers are a bit dated. Therefore I give you:

hash = JSON.parse string 

Rails should automagically load the json module for you, so you don't need to add require 'json'.
