How do you get a nested value item in ant design - reactjs

Question

im quite new on reactJS and also ant design. right now im trying to get a value from a Form.List that i want to make it / render it as json nested data output.
my full code :
import { MinusCircleOutlined, PlusOutlined } from '#ant-design/icons';
import { Button, Form, Input, Space, DatePicker, Select } from 'antd';
import axios from 'axios'
import { useNavigate } from 'react-router-dom'
import Cookies from "js-cookies";
import moment from 'moment';
import 'moment/locale/zh-cn';
const Stockpickingnew = ({ title }) => {
const options = [
{
value: '1',
label: 'True',
},
{
value: '0',
label: 'False',
},
{
value: '7',
label: 'product_tmpl_id'
},
];
const Navigate = useNavigate()
const dateFormat = ['DD-MM-YYYY'];
//---------------------------------------------------------------------------------------------------------------
let headers = {
"Authorization": "Bearer " + Cookies.getItem('access_token')
}
const onFinish = (values) => {
console.log('Success:', values);
let stockpick = {
date: moment(values.date).format("DD-MM-YYYY"),
origin: values.origin,
picking_type_id: values.picking_type_id,
location_id: values.location_id,
location_dest_id: values.location_dest_id,
stock_move_ids: [{
demand: values.demand,
done: values.done,
product_uom: values.product_uom,
product_tmpl_id: values.product_tmpl_id,
}]
};
console.log(JSON.stringify(stockpick))
let params = JSON.stringify(stockpick)
axios.post('http://127.0.0.1:5000/api/stockpickings', params, { headers })
.then(() => {
Navigate('/')
})
.catch(error => {
if (error.response) {
console.log(error.response);
}
});
};
const onFinishFailed = (errorInfo) => {
console.log('Failed:', errorInfo);
};
//---------------------------------------------------------------------------------------------------------------

}
export default Stockpickingnew
im sorry if it's really hard to read but basically, what i really want to do is my Form.List can get a value as nested data like :
stock_move_ids: [{
demand: values.demand,
done: values.done,
product_uom: values.product_uom,
product_tmpl_id: values.product_tmpl_id,
}]
my console.log (values) and console.log JSON.stringify(stockpick) do have different result as image below.
first one is from console.log values and the bottom one is from console.log stockpick

Answer 1

stock_move_ids values have 0th index you can access it like this.
let stockpick = {
date: moment(values.date).format("DD-MM-YYYY"),
origin: values.origin,
picking_type_id: values.picking_type_id,
location_id: values.location_id,
location_dest_id: values.location_dest_id,
stock_move_ids: [
{
demand: values?.stock_move_ids?.[0]?.demand,
done: values?.stock_move_ids?.[0]?.done,
product_uom: values?.stock_move_ids?.[0]?.product_uom,
product_tmpl_id: values?.stock_move_ids?.[0]?.product_tmpl_id,
},
],
};
