Is it possible to get a hash storing a specific value in a huge JSON object?

Question

ruby

Good time of the day.
There is a JSON with a huge number of hashes with nested hashes and arrays (which also have arrays and hashes, etc..).
Is it possible to create a specific algorithm that will pull a hash by value?
That is, for example, I need to get the "Farmer" value from the following JSON:

JSON

[{
        "id": 0,
        "firstName": "",
        "lastName": "",
        "middleName": null,
        "email": "",
        "phones": [
            null,
            null
        ],
        "groups": [{
            "id": 0,
            "name": ""
        }],
        "disabled": "",
        "technologies": [{
            "id": 0,
            "name": "",
            "children": [{
                "id": 1,
                "name": "",
                "children": [{
                    "id": 2,
                    "name": "Farmer",
                    "children": []
                }]
            }]
        }],
        "fullName": ""
    },
{
        "id": 0,
        "firstName": "",
        "lastName": "",
        "middleName": null,
        "email": "",
        "phones": [
            null,
            null
        ],
        "groups": [{
            "id": 0,
            "name": ""
        }],
        "disabled": "",
        "technologies": [{
            "id": 0,
            "name": "",
            "children": [{
                "id": 1,
                "name": "",
                "children": [{
                    "id": 2,
                    "name": "Not Farmer",
                    "children": []
                }]
            }]
        }],
        "fullName": ""
    }
]
# И таких хэшей много, все они разные по составу и т.д

I couldn't find any method/gem/algorithm on GitHub/StackOverFlow to do something like:

Ruby Pseudocode

data_hash = JSON.parse("filename.json")
data_hash.get_hash_by_value("Not Farmer")

#Output:
{
        "id": 0,
        "firstName": "",
        "lastName": "",
        "middleName": null,
        "email": "",
        "phones": [
            null,
            null
        ],
        "groups": [{
            "id": 0,
            "name": ""
        }],
        "disabled": "",
        "technologies": [{
            "id": 0,
            "name": "",
            "children": [{
                "id": 1,
                "name": "",
                "children": [{
                    "id": 2,
                    "name": "Not Farmer",
                    "children": []
                }]
            }]
        }],
        "fullName": ""
    }

I.e. You need to get ALL hashes that store a certain value ("In this example, "Not farmer")

Answer 1

The data structure must be a predefined path, otherwise the result will be undefined.

Answer 3

you can use JSONPath - something similar to xpath, allows you to query JSON at different levels of nesting
