using ruby json library to parse json data into a hash some keys missing

lets say I have this json data file

{
  "page": {
    "title": "Example Page"
  },
  "employers": {
    "name": "Jon"
  },
  "employees": [
    { "name": "Mike", "nicknames": ["Superman"] },
    { "name": "Peter", "nicknames": ["Peet", "Peetee", "Peterr"] }
  ]
}

this data.json file exist as a file outside of the script

I have these 3 lines to read and parse it with json ruby library

data = File.read("data.json")
obj = JSON.parse(data)
puts obj.values

in my terminal it comes out to be like this

{"title"=>"Example Page"}
{"name"=>"Jon"}
{"name"=>"Mike", "nicknames"=>["Superman"]}
{"name"=>"Peter", "nicknames"=>["Peet", "Peetee", "Peterr"]}

what happened to employers and employees? now I have the same key or name in this case. Its difficult for me to grab the values to use them.

Employers and employees are the keys for primary hash, and you requested values, that's why you get what you get. Try putting obj .
