Ruby return value inside of hash array

Question

When in my ruby console, a = first is

=> <Ng::EntityConfiguration id: 15881, entity_id: 1, entity_type: "Ng::Company", key: "wpa2.psk", value: "[{"ssid":"LVL6-Staff","password":"987654321", created_at: "2016-11-08 05:13:04", updated_at: "2016-11-08 05:13:04", name: "WIFI/Level 6">

then a.value

will give you => "[{"ssid":"LVL6-Staff","password":"987654321","dhcp":"Enabled"}]"

My question is, how to get the value when object is Password? because when I try with a.value[:password] got an error.

Is a.value a hash inside an array, inside a string? I tried to look at the original record and it doesn't match the pulled about value of a.value. — David G

first.value also will return to you => "[{"ssid":"LVL6-Staff","password":"987654321","dhcp":"Enabled"}]" From original record, you can see it inside value: "" — Amirol Ahmad

Copying and pasting the code causes errors. Had to wrap it in single quotes, instead of double, to get the proper string to exist. Then it worked as I expected. — David G

It is a JSON string, after JSON.parse() is an array with hashes.

>> x = JSON.parse("[{\"ssid\":\"LVL6-Staff\",\"password\":\"987654321\",\"dhcp\":\"Enabled\"}]")
=> [{"ssid"=>"LVL6-Staff", "password"=>"987654321", "dhcp"=>"Enabled"}]
>> x.last['password']
=> "987654321"
