How to add a Fixed value to different list elements:
Input:
{
"happy": "true",
"statistics": [
{
"id": "A",
"min": "2.0",
"max": "10.0",
"avg": "7.9"
},
{
"min": "6",
"max": "6",
"avg": "6"
},
{
"id": "C"
}
]
}Transformer Spec:
[
{
"operation": "modify-overwrite-beta",
// To add the value only if it does not exist, change the operation to "modify-default-beta"
"spec": {
"statistics": {
"*": {
"newValue": "test123"
}
}
}
}
]
Output:
{
"happy": "true",
"statistics" : [ {
"id" : "A",
"min" : "2.0",
"max" : "10.0",
"avg" : "7.9",
"newValue" : "test123"
}, {
"min" : "6",
"max" : "6",
"avg" : "6",
"newValue" : "test123"
}, {
"id" : "C",
"newValue" : "test123"
} ]
}
Add Dynamic Values
To dynamically add value, use, for instance, the following Transformer Spec:
[
{
"operation": "modify-overwrite-beta",
// To add the value only if it does not exist, change the operation to "modify-default-beta"
"spec": {
"statistics": {
"*": {
"newValue": "@(3,happy)"
}
}
}
}
]
Remark: In the above example, number "3" indicates the number of levels that must be uploaded to access the JSON object. To better understand it, see another example below:
Input:
{
"levelA": {
"levelB": {
"happy": "true"
}
},
"levelX": {
"statistics": [
{
"id": "A",
"min": "2.0",
"max": "10.0",
"avg": "7.9"
},
{
"min": "6",
"max": "6",
"avg": "6"
},
{
"id": "C"
}
]
}
}Transformer Spec:
[
{
"operation": "modify-overwrite-beta",
"spec": {
"nivelX": {
"statistics": {
// the item "*" (all list elements, it is also considered a level)
"*": {
"newValue": "@(5,levelA.levelB.happy)"
}
}
}
}
}
]
