Sorry. I want to remove duplicate from array of hashes on basis of attributes i.e “userid”. For example
Input


    "phonebook": [
        {
            "contact_id": 1,
            "user_id": 13,
            "userid": 2,
            "username": "Tester"
        },
        {
            "contact_id": 1,
            "user_id": 13,
            "userid": 2,
            "username": "Tester"
        },
        {
            "contact_id": 3,
            "user_id": 13,
            "userid": 22,
            "username": "Tester"

    },
    {
        "contact_id": 3,
        "user_id": 13,
