convert json string to hash

rubyonrails-talk
1

I have a string object which is basically in a json format and while trying to print it shows in console as

item =
 {
        "id": "4c9f83e4-f479-48d0-9f92-3fff70a8f6ba",
         "item": "{"business":"1114","class":"Demo","date":"01-01-2014","version":"","data":"dummy","name":"Finance"}"
   
    }

I need to get the values of business, class, date etc and pass it as params to my method. So I tried to convert it into hashes as below

hash_item = JSON.parse (item)

and output in console shows as

The converted hash item is
{"guid"=>"4c9f83e4-f479-48d0-9f92-3fff70a8f6ba", "item"=>"{"business":"1114","class":"Demo","date":"01-01-2014","version":"","data":"Dummy","name":"Finance"}"}

But when I try to access the hash value for business as hash_item['item']['business'] it shows

“business”

since the value of item is a String in the hash_item. I am not sure whether my approach is correct or not. So is there any better idea or any inputs to retrieve the hash values . Please help.

Let me try to explain by example...

JSON demo 1:

{   "id": "4c9f83e4-f479-48d0-9f92-3fff70a8f6ba",   "item": {     "business": "1114",     "class": "Demo",     "date": "01-01-2014"   } }

item = "{\"id\": \"4c9f83e4-f479-48d0-9f92-3fff70a8f6ba\",\"item\": {\"business\": \"1114\",\"class\": \"Demo\", \"date\": \"01-01-2014\"}}"

json = JSON.parse(item) => {"id"=>"4c9f83e4-f479-48d0-9f92-3fff70a8f6ba", "item"=>{"business"=>"1114", "class"=>"Demo", "date"=>"01-01-2014"}}

json['id'] => "4c9f83e4-f479-48d0-9f92-3fff70a8f6ba"

json['item'] => {"business"=>"1114", "class"=>"Demo", "date"=>"01-01-2014"}

json['item']['business'] => "1114"

json['item']['class'] => "Demo"

JSON Demo 2:

{   "id": "4c9f83e4-f479-48d0-9f92-3fff70a8f6ba",   "item": "{"business": "1114","class": "Demo", "date": "01-01-2014""   }" }

item = "{\"id\": \"4c9f83e4-f479-48d0-9f92-3fff70a8f6ba\", \"item\": \"{"business": "1114", "class": "Demo", "date": "01-01-2014"}\"}"

json = JSON.parse(item) => {"id"=>"4c9f83e4-f479-48d0-9f92-3fff70a8f6ba", "item"=>"{"business": "1114", "class": "Demo", "date": "01-01-2014"}"}

json['id'] => "4c9f83e4-f479-48d0-9f92-3fff70a8f6ba"

json['item'] => "{"business": "1114", "class": "Demo", "date": "01-01-2014"}"

json['item']['business'] => "business"

It appears to me you're seeing something like "JSON Demo 2". What you want is what you see in "JSON Demo 1".
