convert json string to hash and retrieve hash items values in ruby
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","service_class":"DataServicesBalancesRaw","start_date":"2014-05-08","calc_version":"","data":"8b698df0-3673-4057-b71a-080d254c355d^^","queue_name":"high"}"}
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.
