How can i rename a field using mapneat, wich is inside list object like this

    {
    "detail" : [
        {
            "name" : "huda"
        },
        {
            "name" : "syahnaz"
        }
    ]
    }

into this

{
      "detil" : [
          {
              "nama" : "huda"
          },
          {
              "nama" : "syahnaz"
          }
      ]
  }

i try to transform it like this, but doesn't work

fun test(jsonRequest: String, setup: String): MapNeat {
 
         val transform = json(MapNeatSource.fromJson(jsonRequest)){
             "detil[*].nama"*="detail[*].name"
         }
         return transform;
     }

The code that is performing what you are looking for:

val source = """
{
    "detail" : [
        {
            "name" : "huda"
        },
        {
            "name" : "syahnaz"
        }
    ]
    }
"""

fun main() {

    var value = json(fromJson(source)) {
         "detail" *= "$.detail"
        val detail = getObjectMap().get("detail") as List<Object>

        "detil" /= detail.map {
            json(fromObject(it)) {
                "nama" *= "$.name"
            }
        }.toList()

        - "detail"
       
    }.getPrettyString()

    print(value)
}

Output:

{
  "detil" : [ {
    "nama" : "huda"
  }, {
    "nama" : "syahnaz"
  } ]
}

Hope it helps.

The main idea is to:

• Select "detail" from source to target: "detail" *= "$.detail"
• After this line, it becomes accessible inside getObjectMap() which keeps the internal representation of the target as Map<String,Object>. You cast the result to List` (because it's an array).
• Then you iterate over detail, and apply a new transformation for each element.
• You remove "detail" at the end because you don't need it anymore.

Hope it helps
