adding array of objects to existing objects

Question

I have an existing params object as following

{
 "application_context": {
 "application_id": "a0",
 "context_id": "c0"
 },
 "device_data": {
 "device_id": "",
 "hostname": ""
 },
 "query_options": {
 "page_token": "",
 "page_size": 30
 }
}

My desired object should be following

{
 "application_context": {
 "application_id": "a0",
 "context_id": "c0"
 },
 "device_data": {
 "device_id": "",
 "hostname": ""
 },
 "query_options": {
 "page_token": "",
 "page_size": 30,
 "filter_list": [{
 "operator": "OPERATOR_AND",
 "field_list": [{
 "field": "State",
 "value": "INACTIVE_STATE"
 }]
 }]
 }
}

I have created the following

param['filter_list'] = [{
 'operator': 'OPERATOR_AND',
 'field_list': filter
 }];

where it's adding the following part with some logic

"field": "State",
"value": "INACTIVE_STATE" 

But not able to add the above to get my complete object

• Angen: have you tried nameOfYourObject["query_options"].filter_list = param["filter_list"] ?

Answer 1

You need to create filter_list on query_options key

let data = {
 "application_context": {
 "application_id": "a0",
 "context_id": "c0"
 },
 "device_data": {
 "device_id": "",
 "hostname": ""
 },
 "query_options": {
 "page_token": "",
 "page_size": 30
 }
}
data.query_options.filter_list = [{
 "operator": "OPERATOR_AND",
 "field_list": [{
 "field": "State",
 "value": "INACTIVE_STATE"
 }]
}];
console.log(data)

Answer 2

You can add your data as: obj["query_options"]["filter_list"] = param["filter_list"];

var obj = {
 "application_context": {
 "application_id": "a0",
 "context_id": "c0"
 },
 "device_data": {
 "device_id": "",
 "hostname": ""
 },
 "query_options": {
 "page_token": "",
 "page_size": 30
 }
 };
 
 var filter = [{
 "field": "State",
 "value": "INACTIVE_STATE"
 }];
 /*param['filter_list'] = */ 
 var filter_list = [{
 "operator": "OPERATOR_AND",
 "field_list": filter
 }]
 
 obj["query_options"]["filter_list"] = filter_list ;
 
 console.log(obj);
