ROR - Extract ID from HTTP response location

Question

I have a REST call to Java services which does a POST to the path

localhost:8080/api/xyz

and returns the response. The response of course has the response.header['location'] with a correct location with ID

'xyz/{id}'

For my further steps in the method I just need to extract ONLY the 'id' part from the 'location'. Right now this is what I am doing,

(response.header['location'].split('/'))[1]

Is there a better way to get around this?

This will fail if the location field value would be a full URI, right? Better resolve it first against the base URI, then use an URI parser to extract the path, then proceed. — Julian Reschke, Mar 12 '14 at 17:01

One of the solution provided by rails:

# routes.rb
get '/api/:id'

# view or controller
params[:id]

This is nothing to do with the routes in rails. This a request coming in from JAVA services via REST call. :) – Abhi Mar 12 '14 at 16:48
REST is good for rails. I think `active_resources` will help you in the goal https://github.com/rails/activeresource – itsnikolay Mar 12 '14 at 16:53
Let me look into it. Thank you. – Abhi Mar 12 '14 at 17:02
