How to return id in JSON (Rails) -

i'm learning ruby on rails.

my http://localhost:3000/locations.json returns following:

[{   "name":"abc",   "address":"xyz",   "latitude":12.3,   "longitude":14.5,   "url":"http://localhost:3000/locations/1.json" }]

how modify locations_controller.rb in order json return id, without parsing url?

[{   "id":1,   "name":"abc",   "address":"xyz",   "latitude":12.3,   "longitude":14.5,   "url":"http://localhost:3000/locations/1.json" }]

my current locations_controller.rb contains this:

def index   puts "index"   @locations = location.all end

thank you.

you try framework rabl gives greater control on output of json. allow specify included in json response.
