I am encountering an issue where my code is functioning correctly in the console but it is not saving data to the database. Every time I restart the server, the data gets reset. While I can read data from the database without any problem, the issue arises when trying to update or create new data as intended. Below is the snippet of code from my server.js file:
var express = require('express');
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var bodyParser = require('body-parser');
var app = express();
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://localhost:27017/food');
//Allow all requests from all domains & localhost
app.all('/*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With, Content-Type, Accept");
res.header("Access-Control-Allow-Methods", "POST, GET");
next();
});
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
var usersSchema = new Schema({
_id: String,
id: String,
vote: Number
});
var bkyes = mongoose.model('bkyes', usersSchema);
app.post('/bkyes', function(req, res, next) {
bkyes.find({}, function(err, foundObject) {
console.log(foundObject); //Print pre-update
var found = foundObject[0];
found.vote = req.body.vote; //Passing in the number 5 here(was -1 before)
found.save(function(err) {
console.log(foundObject); //Print post-update
});
});
});
app.listen(3000);
/*
The console.log pre-update:
[ { _id: '582b2da0b983b79b61da3f9c', id: 'Burger King', vote: -1 } ]
^
The console.log post-update:
[ { _id: '582b2da0b983b79b61da3f9c', id: 'Burger King', vote: 5 } ]
^
However this data does NOT write to the db and just resets when you restart the server!!
