Transform runs multiple times in nested array #77
Description
Hello!
I have a use case where I'm trying to transform a key in a deeply nested array + object structure. See example below:
var objectMapper = require('object-mapper');
var map = {
'[].data.children[].person_id': {key: 'entity[].humans.children[].person.id', transform: (e) => e+'_+1'},
};
var arr = [{
"id": "1",
"data": {
"children": [
{
"person_id": "123123123"
},
{
"person_id": "12312312"
},
{
"relation_id": "111"
}
]
}
}];
var dest = objectMapper(arr, map);
console.log(JSON.stringify(dest, null, 4))I was expecting an output of:
{
"entity": [ {
"humans": {
"children": [ {
"person": {
"id": "123123123_+1"
}
},
{
"person": {
"id": "12312312_+1"
} } ]
}
} ]
}Instead, I get:
{
"entity": [ {
"humans": {
"children": [ {
"person": {
"id": "123123123,12312312_+1_+1"
}
}
]
}
}
]}I'm doing some further debugging now, but it appears the transform() function gets called multiple times in the array iteration.
