Data model API

In scripts, validators, and script tasks we can use the data model API

interface Model {
   get(key || key[] :string): string;                    // Retrieving a variable from the data model with the specified id
   indexes(key[] : string): List<String>;                // Retrieving indexes of the given key from the array
}

GET

To use values from the data model, use the API presented in the code fragment below:

function callService(input){
    const valueFromModel = api.model.v1.get("user.pesel"); // Retrieving the PESEL from a single model node -> "12312312311"
    let customersLastName = api.model.v1.get("BazaOfert.Kredytobiorcy[0].Nazwisko") // Retrieving the surname from index 0 -> "Kowalski"
    let customersPesel = api.model.v1.get("BazaOfert.Kredytobiorcy[].PESEL") //Retrieving all PESELs from the array -> "74082109492,49020106066"
    return [{'output':customerLastName}]
}

INDEXES

To retrieve the list of indexes for an array, use the API presented in the code fragment below:

 const answersIndexes = api.model.v1.indexes("Survey.Questions[]")
 let surveyResults = answersIndexes.map((idx) => {
        return {
            "question": api.model.v1.get(`Survey.Questions[${idx}].Content`),
            "answer": api.model.v1.get(`Survey.Questions[${idx}].Answer`)
        }
    })
