rails - call json api and parse one value in response

Question

I'm calling a json api and retrieving this as the result every single time:

{
  "@endDate": "2016-11-05",
  "@metric": "Sessions",
  "@startDate": "2016-11-05",
  "@generatedDate": "11\/5\/16 6:14 PM",
  "@version": "1.0",
  "day": {
    "@date": "2016-11-05",
    "@value": "8174"
  }
}

I want to get the number 8174 in a variable in rails, how do I do this?

Assign your json response to `response` variable

response = { "@endDate": "2016-11-05", "@metric": "Sessions", "@startDate": "2016-11-05", "@generatedDate": "11\/5\/16 6:14 PM", "@version": "1.0", "day": { "@date": "2016-11-05", "@value": "8174" } }

Parse it

parsed_response = JSON.parse(response.to_josn)

After parsing `parsed_response` is now a hash. So you can access the `number` from `parsed_response` hash

get_number = parsed_response['day']['@value']

getting this error ActionView::Template::Error (no implicit conversion of Hash into String): Thank you

By any chance, do you know what would be the best way to call the api? I just realized I worded this questions as if that part was done. Thank you

Edited. I forgot to add to_json. To call an api I usually use rest-client gem and receive the response this way(my answer).
