With below schema i am trying to find with selected fields. In result I receive only first 2 org_name and description, but others not receiving. any idea. I am new to mongoose. I am not able to find any reason from documentation too. Any help will be appreciated.
My schema:
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
let JobsSchema = new Schema ({
_id: {type:String, required: true, max:100},
sector: {type:String, required: true, max:100},
category: {type:String, required: true, max:100},
apply_mode: {type:String, required: true, max:100},
org_name: {type:String, required: true, max:100},
description: {type:String, required: true},
start_date: {type: Date},
end_date: {type: Date},
total_openings: {type: Number},
total_openings_description: {type:String},
min_salary: {type: Number},
max_salary: {type: Number},
salary_description: {type: String},
apply_steps: {type: String},
tags: [],
additional_dates: [{
additional_date_label: {type:String, required: true, max:100},
additional_date_value: {type:Date},
}],
age_limits: [{
age_limit_label: {type:String, required: true, max:100},
age_limit_min_value: {type: Number},
age_limit_max_value: {type: Number},
}],
application_fees: [{
application_fee_label: {type:String, required: true, max:100},
application_fee_value: {type: Number},
}],
url_links: [{
url_link_label: {type:String, required: true, max:100},
url_link_value: {type:String, required: true, max:100},
}]
},
{ collection: 'Jobs' }); // this line to match name in db
module.exports = mongoose.model('jobs', JobsSchema);
My query:
Job.find(
{},
"org_name description start_date end_date total_openings min_salary max_salary",
{ sort: { start_date: "asc" }, skip: pageNumber * pageSize, limit: pageSize },
(err, jobs) => {
if (err) {
res.render("error", {
errMsg: "issue in getting records. Try after sometime.",
errBody: err
});
}
if (jobs) {
res.render("listJob", {
jobs: jobs
});
}
}
);
Result
[
{
"_id": "Job1",
"org_name": "Test org",
"description": "<p>Test Desc</p><p><b>Hello world</b></p>"
},
{
"_id": "Job2",
"org_name": "Test org11",
"description": "<p>Test descr</p>"
},
{
"_id": "Job10",
"org_name": "Test inc 1",
"description": "<p>,smdfndfskj</p>"
}
]
I finally found that projection fields should be there in all documents then only it will apply.

I'm new to building rest api's with mongoose and express and have a question on how to use refPath correctly on my Models files and allowing for an array of items.
Below I have included the code for a model (built thus far) and would love any input on if I'm even close to building this correctly.
I will also include a screenshot that visually depicts the relationships I'm trying to create.
Those who answer questions here are GODS and I appreciate all the help this community has given me over the years!
const mongoose = require("mongoose");
const slugify = require("slugify");
const AlertSchema = new mongoose.Schema({

Desired relationships diagram:
Is it possible to use mongoose's Populate Virtuals to populate the array of values it is referencing?
User Model
var userSchema = new mongoose.Schema({
auth_key: {type: String},
channels: [{
name: {type: String},
last_access: { type: Date, default: Date.now },
status: {type: String, default: false },
new_messages: {type: Number},
user_channel_group: {type: String}
}]
}, {
toJSON: {
virtuals: true
}
});
userSchema.virtual('channels.details', {
ref: 'channel',
localField: 'channels.name',
foreignField: 'name'
});
var user = mongoose.model('user', userSchema, 'user');
Channel Model
var channelSchema = new mongoose.Schema({
name: {type: String, required: true},
members: [{ type: String, required: true }],
displayName: {type: String},
type: {type: Number},
create_at: {type: Date, default: Date.now}
});
var channel = mongoose.model('channel', channelSchema, 'channel');
My query that I am using I want the virtual to present the channel details from each channel alongside the channels a user is subscribed to. so something like this..
[{
"_id": "588a82ff7fe89686fd2210b0",
"channels": [{
"details": {
"_id": "588a80fd7fe89686fd2210a8",
"name": "channel1",
"members": []
},
"name": "channel1"
}, {
"details": {
"_id": "588a80fd7fe89686fd2210a9",
"name": "channel2",
"members": []
},
"name": "channel2"
}],
"id": "588a82ff7fe89686fd2210b0"
}
...
]
My Query for this is ..
user.find({}).populate('channels.details').exec()
This is my schema:
Appliance = new Schema({
appliance_name: {type:String},
appliance_id: {type:String},
appliance_description: {type:String},
keywords: [{ type: String}],
appliance_type: { type: String},
appliance_status: { light: { write_state: Number, read_state: Number },
fan: {write_state: Number, read_state: Number, write_speed: Number, read_speed: Number}
}
});
Room= new Schema({
name: {type: String, required:true},
device_auth_code: {type: String},
alt_name: {type:String},
keywords: [{type: String}],
appliance: [Appliance]
});
Home = new Schema({
name: { type: String, required: true},
description: {type: String},
administrator: {type : mongoose.Schema.Types.ObjectId, ref: 'User', required: true},
users: [{
_id: {type : mongoose.Schema.Types.ObjectId, ref: 'User'},
email: {type: String},
name: { type: String},
status: { type: Number}
}],
rooms: [Room]
});
And here is the typical home.
"type": true,
"code": "GET_SUCCESS",
"homes": {
"_id": "58760ff6045e332b81449b42",
"description": "",
"administrator": "586df1e06485de5fc48b72a5",
"name": "CM",
"__v": 9,
"rooms": [
{
"name": "RK",
"alt_name": "RKa",
"_id": "58775437234451346ce3d967",
"appliance": [
{
"_id": "5877546f234451346ce3d968",
"appliance_type": "Light",
"appliance_name": "TubeLights",
"keywords": []
}
],
"keywords": []
}
],
"users": []
}
}
Home has nested array of rooms and each room has nested array of appliances.
Home.findOne({'room.appliance._id': appliance_id}) would return the whole document. The $ operator wouldn't work I would have to imagine.
Is it possible to receive that particular appliance or the whole document with that particular room and appliance only being returned?
How do I find a particular appliance and return that appliance?
Here you've used mongoose subdocs architecture in your home schema definition. So you could retrieve any particular room:
Home.findById(home_id, function(err, home){
var room = home.rooms.id(room_id);
res.json(room)
});
or a particular appliance:
Home.findById(home_id, function(err, home){
var room = home.rooms.id(room_id);
var appliance = room.appliance.id(appliance_id);
res.json(appliance)
});
i want to store data like this but i have made schema but i don't think i have made right way please some one suggest me to get this done

i have added my schema design .is that design right? some one help me out bcoz when i update particular field it's not updating
I'm trying to create a webapp with mongoose and nodejs. This is the first time i'm using mongoose and nodejs so i'm not quit good at it.
I have a person model:
var PERSON = new mongoose.Schema({
name: {type: String, required: true},
zipcode: {type: String, required: true},
city: {type: String, required: true},
street: {type: String, required: true},
address: {type: Number, required: true},
email: {type: String, required: true},
type: {type: String, enum: ['lid', 'passant'], required: true},
ships: {
type: [{
name: {type: String, required: true},
length: {type: Number, required: true},
type: {type: String, required: true},
picture: {type: Buffer, required: false}
}],
required: false
},
user: {
type: {
userName: {type: String, required: true},
password: {type: String, required: true},
passwordKey: {type: String, required: true},
roles: {type: [{type: mongoose.Schema.Types.ObjectId, ref: 'role'}], required: true}
},
required: false
}
},
{
collection: 'PERSON'
});
And the rol model:
var ROLE = new mongoose.Schema({
name: {type: String, required: true}
},
{
collection: 'ROLE'
});
When i'm trying to run a find query on the person model, I want to populate the user.roles array. But as a result it remains empty.
/ GET a specific person by id or type/
server.get('/api/person/:id', function (req, res, next) {
if (helper.isValidObjectID(req.params.id)) {
person.findById(req.params.id).populate("user.roles").exec(function (err, result) {
if (err) {
res.status(404).json(err);
} else {
res.status(200).json(result);
}
}
);
} else {
next();
}
}, function (req, res, next) {
person.find({type: req.params.id}).populate('user.roles').exec(function (err, result) {
if (err) {
res.status(404).json(err);
} else {
res.status(200).json(result);
}
});
});
and as a result i get:
{
"_id":"553f79d4f1481c0c14b42d59",
"name":"Wilco Boogert",
"zipcode":"4305RH",
"city":"Ouwerkerk",

},
"__v":0,

"name":"titanic",
"length":269,
"type":"Olympic-klasse",
"_id":"553f79d4f1481c0c14b42d5a"
}
]
}
The orginal object in the database is:
{
"_id": {

},
"name": "Wilco Boogert",

"_id": {

}
}
],
"__v": 0
}
so as you an see the roles is empty. And I search the web but i cannot find what the problem is. Can annyone help me?
You should replace this line :
roles: {type: [{type: mongoose.Schema.Types.ObjectId, ref: 'role'}], required: true}
with this one :
roles: {type: [{type: mongoose.Schema.Types.ObjectId, ref: 'ROLE'}], required: true}
In fact, the reference must be the exact same name as it's defined :
collection: 'ROLE'
It's case sensitive.
