access values in json, specially through ROR - json

Question

"divisions":{
"ocd-division/country:us/state:co/place:aurora":{
"name":"Aurora city",
"scope":"citywide",
"officeIds":[
"O0",
"O1"]
}}
I am using Google Civic Information API to get representive information. let's say this is a part of JSON generated by Google and I want to access its elements but the issue is - i cant use "ocd-division/country:us/state:co/place:aurora" as a key, because its dynamically generated by Google.
If I search for some different address like India, the key will be different from "ocd-division/country:us/state:co/place:aurora" to something else(instead of 'us', there would be 'in'), So please suggest the way I should access in this case the value.
Please clarify if you don't understand question or need more clarification.

Answer 1

Parse the json to a hash:
parsed_data = JSON.parse google_data
then either iterate over all divisions:
parsed_data['divisions'].each do |division_key, division_info|
# do something with each division
end
or get only the first one:
division_key, division_info = parsed_data['divisions'].first
Use this if you want parse the key as well:
more_info = division_key.split('/').inject(Hash.new) do |hash, key_part|
if key_part.include? ":"
key, value = key_part.split ":"
hash[key] = value
end
hash
end
Now you can access it via more_info['country']
