MongoDB how to populate - node.js

Question

i have 2 Schemas. 1. ProjectBug and 2. ProjectBugImage so i am uploading an image and saving it in a different collection.
See the Schemas below Number 1
const mongoose = require('mongoose');
let ProjectBugSchema = new mongoose.Schema({
projectID: {
type: mongoose.Schema.ObjectId
},
completed: {
type: Boolean,
default: false
},
components: Boolean,
groupSelect: String,
appsAffected: Array,
title:String,
description:String,
selectedcomponents: Array,
resources: Array,
isLive: Boolean,
issueNumber: String,
projectBugMianID: String,
date: String,
reporter: String,
foundOn: String,
testedDevel: Boolean,
testedLive: Boolean,
testedStaging: Boolean,
platform: String,
linked: Boolean,
linkedTo: String,
type: String,
appPassword: String,
appUsername: String,
percentageComplete: String,
status: String,
releaseID: {
type: String
},
createdAt:{
type: Date,
default: Date.now
},
},{
timestamps: true
},{
toJSON: { virtuals: true },
toObject: { virtuals: true },
});
ProjectBugSchema.virtual('bugImage', {
ref: 'bugImage',
localField: '_id',
foreignField: 'bugID'
});
module.exports = mongoose.model('ProjectBug', ProjectBugSchema);
Number 2
const mongoose = require('mongoose')
const ProjectBugImageSchema = new mongoose.Schema({
bugID:{
type: mongoose.Schema.ObjectId,
},
fileName:{
type: String,
},
path: {
type: String,
},
createdAt: {
type: Date,
default: Date.now
}
});
module.exports = mongoose.model('bugImage', ProjectBugImageSchema)
And then i my controller i have
exports.index = (req, res) => {
ProjectBug.find({})
.populate('bugImage', '', null, { })
.exec((err, bugs) => {
if(err){
res.send(err)
}
res.send(bugs)
})
}
Strange thing is this used to work, and now it does not anymore, as you can see i have the ProjectbugSchema.vertual('bugImage', {...}) with the ref to bugImage and the local field to _id and foreignField to 'bugID' so that would match the ProjectBugImage.bugID with the local field of ProjectBug _id
what i get when i get data. Response
{
"completed": false,
"appsAffected": [],
"selectedcomponents": [],
"resources": [],
"_id": "5e8195fcc7939644cc322793",
"groupSelect": "",
"title": "asdasd",
"description": "<p>asdasd</p>",
"issueNumber": "",
"date": "2020-03-30",
"reporter": "5d305d3a9fe62f5578d0e209",
"type": "bug",
"foundOn": "",
"isLive": false,
"testedDevel": false,
"testedLive": false,
"testedStaging": false,
"platform": "",
"appUsername": "",
"appPassword": "",
"percentageComplete": "",
"status": "",
"createdAt": "2020-03-30T06:47:24.751Z",
"updatedAt": "2020-03-30T06:47:24.751Z",
"__v": 0
}
All i want is all the images that has bugID to be with the projectbug where the ids match. and put them into an array. Am i doing something wrong in the populate?? or somewhere else?

Answer 1

So i figured it out, in the model where i create the virtual i had
,{
toJSON: { virtuals: true },
toObject: { virtuals: true },
});
I took that out closed the Schema and underneath i put
ProjectBugSchema.set('toObject', { virtuals: true })
ProjectBugSchema.set('toJSON', { virtuals: true })
Small change but seems to be the answer.
