Nodejs Mongodb update multiple collections - node.js

Question

In mongodb have two collections for now Event and Packages. So basically the model looks like this
Event Model
const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
const Schema = mongoose.Schema;
const bcrypt = require('bcrypt-nodejs');
const EventSchema = new Schema({
_id: mongoose.Schema.Types.ObjectId,
eventname: {
type: String,
required : true,
},
eventdesc: {
type: String,
required : true,
},
createdAt: {
type: Date,
default: Date.now
},
updatedAt: {
type: Date,
default: Date.now
}
});
module.exports = mongoose.model('Event', EventSchema);
Package Model looks like this
const mongoose = require('mongoose');
mongoose.Promise = global.Promise;
const Schema = mongoose.Schema;
const bcrypt = require('bcrypt-nodejs');
const PackageSchema = new Schema({
_id: mongoose.Schema.Types.ObjectId,
eventpackages: {
type: Object,
required : false,
},
event: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Event'
},
createdAt: {
type: Date,
default: Date.now
},
updatedAt: {
type: Date,
default: Date.now
}
});
module.exports = mongoose.model('Package', PackageSchema);
Here I am trying to update an event so when the event will be updated the packages will be updated also. So in nodejs I have done like this
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
/* UPDATE EVENT */
router.put('/:id', function(req, res, next) {
upload(req, res, function(err) {
let EventData = {
eventname : req.body.eventname,
eventdesc : req.body.eventdesc,
}
let EventPackages = {
eventpackages : req.body.sections,
}
Event.findByIdAndUpdate(req.params.id, EventData, function (err, post) {
if (err) return next(err);
Package.findAndModify({
query: { event: req.params.id },
update: { $inc: { EventPackages } },
new: true,
upsert: true
})
res.json(post);
});
});
});
module.exports = router;
But its not working at all. If I will deleted the codes for package update it will work for events.
So can someone tell me how to make this work so that I can update multiple collections at a time.

Answer 1

you can try this,
var query = {
'event': req.params.id
};
var dataToUpdate = {
$set: {
///
}
};
Package.updateMany(query, datatoUpdate, function(err, result) {
if (err) return handleError(err);
return Promise.resolve(result);
});
