Retain some json key value pairs while transforming them using jolt - json

Question

I just started learning jolt. I want to transform a json to a desired format. I'm almost done but stuck with this point
My input json looks like
{ "first_name": {
"label": "First name",
"type": "text",
"value": "John"
},
"last_name": {
"label": "Last name",
"type": "text",
"value": "Doe"
},
"email": {
"label": "Email",
"type": "text",
"value": "johndoe#gmail.com"
}
"id": 123,
"marital_status": "Single",
"author_id": null,
"company": null,
"address": {
"city": {
"label": "city",
"dom_type": "dropdown",
"value": "test"
},
"state": {
"label": "state",
"dom_type": "dropdown",
"value": "state"
},
"country": {
"label": "country",
"dom_type": "dropdown",
"value": "country"
}
}
}
to an output format like this
{
"first_name" : "John", "last_name" : "Doe", "email" : "johndoe#gmail.com",
"id": 123, "marital_status": "Single", "author_id": null, "company": null,
"address" : { "city" : "test", "state" : "test", "country" : "test" }
}
I have tried this shift spec
[
{
"operation": "shift",
"spec": {
"address": {
"*": {
"#value": "address.&1"
}
},
"*": {
"#value": "&1"
}
}
}
]
And got
{
"first_name" : "John", "last_name" : "Doe", "email" : "johndoe#gmail.com", "address" : { "city" : "test", "state" : "test", "country" : "test" }
}
Because the matcher "*" discards the simple key value pairs. I know that I'm missing something. Any help?

Answer 1

Because the matcher "*" discards the simple key value pairs. -> It isn't discarding them, it is matching them, but not finding a sub-property of "value".
Your input data is fundamentally in 3 different formats
Things below address
Things that are singular in value like "id"
Things that have nested data
The "*" just matches the Left-hand-side / key.
In this case you will need to explicitly list either the keys that are singular, or the keys that have nested data.
Spec
[
{
"operation": "shift",
"spec": {
"address": {
"*": {
"#value": "address.&1"
}
},
"id|marital_status|author_id|company": "&",
"*": {
"#value": "&1"
}
}
}
]
