ruby - Rails 4 - Parsing and iterating through Google Places API JSON response -

using rails 4 http gem make simple requests. hitting googles api url , couple of parameters in order return nearby stadiums in json.

my goal here iterate through of different stadium results , pull out photo_reference.

i able pull out photo_reference first array so:

def nearby_places(lat, long)   response = http.get("https://maps.googleapis.com/maps/api/place/nearbysearch/json?key=mykey&location=#{lat},#{long}&radius=3000&types=stadium")   parsed_response = json.parse(response.body)   parsed_response["results"][0]["photos"][0]["photo_reference"] end 

but having trouble iterating through , pulling out photo references if multiple stadiums returned. best way go this?

here example response google.
