[英]How to get two tables data in Node.js with object inside other object
I have two tables and I need data in this format. 我有两个表,我需要这种格式的数据。 How is this Possible? 这怎么可能?
Required Output 所需输出
{
"id":"1",
"name":"akhil",
"pics": [
{
"pic1": "123.jpg",
"pic2": "123.jpg"
}
]
}
Generally I use this for getting data from single table 通常我用它来从单个表中获取数据
const express = require('express');
const app = express();
const jwt = require('jsonwebtoken');
const bcrypt = require('bcryptjs');
const config = require('./config');
var VerifyToken = require('./VerifyToken');
const mysql = require('mysql');
app.use(express.json());
const connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : 'password',
database : 'sample'
});
app.get('/usersdata', VerifyToken, (req, res) => {
let id = req.userId;
console.log(req.userId);
connection.query("select * from users", function (error, results, fields) {
if (error) throw error;
else {
res.send({"result": results});
}
});
})
My Solution: 我的解决方案:
app.get('/usersdata', (req, res) => {
connection.query("select u.id, u.name, p.pic1, p.pic2 from users u, pics p where u.usersid=p.id", function (error, results, fields) {
if (error) throw error;
else {
let data = results;
let newResult = {};
results.map(row => {
if(newResult[row.id]) {
newResult[row.id].pics.push(row.pic1, row.pic2)
} else {
newResult[row.id] = { id: row.id, name: row.name, pics: [row.pic1, row.pic2] };
}
})
res.send({ "result": Object.values(newResult) });
}
});
})
