Now the Person class is REST enabled and can invoke REST services very similarly to how Active Record invokes
life cycle methods that operate against a persistent store.
h3. Reading and Writing Data
Active Resource make request over HTTP using a standard JSON format. It mirrors the RESTful routing built into Action Controller but will also work with any other REST service that properly implements the protocol.
h4. Read
Read requests use the GET method and expect the JSON form of whatever resource/resources is/are being requested.
<ruby>
# Find a person with id = 1
ryan = Person.find(1)
# Check if a person exists with id = 1
Person.exists?(1) # => true
# Get all resources of Person class
Person.all
</ruby>
