Is it possible to convert a JSON string into a Ruby object? I would like to access its information with an expression similar to:

drawer.stations.tv.header 

JSON string:

{   "drawer" : {     "stations" : {       "tv" : {         "header" : "TV Channels",         "logos" : {           "one" : "www1",           "two" : "www2",           "three" : "www3"         }       }     }   } } 

Answer 1

You can parse the string into a ruby hash and then turn it into a Mash. Mash provides you with method-like access.

require 'json' require 'hashie'  hash = JSON.parse json_string obj = Hashie::Mash.new hash obj.drawer.stations.tv.header # => "TV Channels" 

Update

You can also do it without a 3rd party gem, using ruby's own OpenStruct:

require 'ostruct' require 'json'  obj = JSON.parse(json_string, object_class: OpenStruct) obj.drawer.stations.tv.header # => "TV Channels"
