Get a particular key value from json in ruby

Question

[  "KEY1":{"SUB_KEY1" : "VALUE1","SUB_KEY2" : "VALUE2"}, "KEY2":{"SUB_KEY1" : "VALUE1","SUB_KEY2" : "VALUE2"} ] 

The above is my json object which is coming as a response.

How do I get SUB_KEY1 of KEY1 and SUB_KEY1 of KEY2 in Ruby on Rails?

Thank you.

Answer 1

You need to parse the JSON object into a ruby hash. Assuming your JSON response is called res:

require 'json' obj = JSON.parse(res)  sv1 = obj['KEY1']['SUB_KEY1'] 

etc.

Answer 2

parsed_json = ActiveSupport::JSON.decode(your_json_string)

will parse your string as

  [{"KEY1"=>{"SUB_KEY1"=>"VALUE1", "SUB_KEY2"=>"VALUE2"}}, {"KEY2"=>{"SUB_KEY1"=>"VALUE1", "SUB_KEY2"=>"VALUE2"}}] 

You should be able to access it using something like parsed_json[1]["KEY2"]["SUB_KEY1"]
