Google Apps Script: Creating and populating a nested JSON object - arrays

Question

I would like to create a JSON object with the following structure:
var exec_log = {
total_correct: 0,
total_error: 0,
[exec_detail: {
timestamp: "1a",
script: "New Deal",
type: "Bot",
id: "2a",
pair: "3a",
status: "4a",
message: "5a"
},
exec_detail: {
timestamp: "1a",
script: "New Deal",
type: "Bot",
id: "2a",
pair: "3a",
status: "4a",
message: "5a"
},
...]
}
However I don't know how to create an array of objects inside an object or how to access them to populate them correctly.
Current code:
So far I have achieved this but I'm sure the array is not defined correctly and I suspect that I have to create an external array and push it inside the exec_log object.. Should I define 2 separated objects and push one inside the other?
function StartNewDeal(filterAPC){
var exec_log = {
total_correct: 0,
total_error: 0,
exec_detail: {
timestamp: "",
script: "New Deal",
type: "Bot",
id: "",
pair: "",
status: "",
message: ""
}
}
for(var i = 0; i < filterAPC.length; i++){
Logger.log("Passing botID: " + filterAPC[i][1])
var new_deal = StartDeal(filterAPC[i][1]);
var currentDate = Utilities.formatDate(new Date(), "PST", "yyyy-MM-dd HH:mm");
exec_log.exec_detail[timestamp[i]] = currentDate;
exec.log.exec_detail[id[i]] = filterAPC[i][1];
exec_log.exec_detail[pair[i]] = new_deal.pair;
if(new_deal.valid == false){
exec_log.exec_detail[status[i]] = "Error";
exec_log.exec_detail[message[i]] = new_deal.json;
exec.log.total_error = exec.log.total_error + 1;
}else{
exec_log.exec_detail[status[i]] = "Completed";
exec_log.exec_detail[message[i]] = "Completed";
exec.log.total_correct = exec.log.total_correct + 1;
}
}
return exec_log;
}

Answer 1

function createObject() {
let obj={property1:'value1',property2:'value2',property3:[],property4:[],property5:'value5',property6:'value6'};
for(let i=0;i<2;i++) {
let iObj={};
for(let j=0;j<5;j++) {
iObj['item'+j]='donkey'+j;
}
obj.property3.push(iObj);
obj.property4.push(iObj);
}
SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput('<textarea>' + JSON.stringify(obj) + '</textarea>'), "Making an object with no parts");
}

Try this:
function StartNewDeal(filterAPC){
var exec_log = {
total_correct: 0,
total_error: 0,
exec_details_list: [] // an array to store your exect_details objects
}
for(var i = 0; i < filterAPC.length; i++) {
Logger.log("Passing botID: " + filterAPC[i][1])
var new_deal = StartDeal(filterAPC[i][1]);
var timestamp = Utilities.formatDate(new Date(), "PST", "yyyy-MM-dd HH:mm");
var id = filterAPC[i][1];
var pair = new_deal.pair;
var status;
var message;
var script; // doesn't seem like you're using this
if (new_deal.valid == false){
status = "Error";
message = new_deal.json;
exec.log.total_error = exec.log.total_error + 1;
} else{
status = "Completed";
message = "Completed";
exec.log.total_correct = exec.log.total_correct + 1;
}
exec_log.exec_details_list.push(new ExecDetailObject(timestamp, script, type, id, pair, status, message));
}
return exec_log;
}
// A function to create new exec_detail objects
// from your code you don't seem to be using the script property. Not sure if that's intentional
function ExecDetailObject(timestamp, script, type, id, pair, status, message) {
this.timestampt = timestamp;
this.script = script;
this.type = type;
this.id = id;
this.pair = pair;
this.status = status;
this.message = message;
}
