Having trouble with the following schema
const FriendRequestSchema = new Schema({
requester: {
_id: {
type: Schema.Types.ObjectId
}
},
profilePicture: String,
pending: {
type: Boolean,
default: true
}
})
the way i create a new friend request
const friendRequest = new FriendRequest({
requester: {
_id: req.user._id
},
profilePicture: req.user.profilePicture
})
results object
{
"pending": true,
"_id": {
"$oid": "5ab4fdb07525fd6880d1a6b9"
},
"profilePicture": "/assets/profile_icons/glasses.png"
}
now the problem is:
im missing the requester field
the id field is always different and dosent save the requester id
how can i fix this ?
Try change you schema like this:
requester: {
type: Schema.Types.ObjectId,
required: true,
ref: 'User', // depends on how you called user schema
},
Usage:
const friendRequest = new FriendRequest({
requester: req.user._id,
profilePicture: req.user.profilePicture
})

const query = { _id: req.params.frameworkId, _id: req.params.domainId };//pushing into the framework model by taking the ID from URL
await Framework.updateOne(query, { $push: { domains: control } }).exec(); //push the query into the framework model
res.status(200).json({
success: true,
controls: control
});
} catch (error) {
res.status(400).json({
// error: 'Your request could not be processed. Please try again.'
error
});
}

Problem: I'm not getting any new data in mongodb , any idea if I'm approaching this the correct way? I'm guessing the data is posted correctly and It's a problem with saving it to the database
Picture of my schema: I want to be able to add elements under the controls:
First if you want your code to insert and not update you should use insertOne and not updateOne, regarding an "update" operation I can see 2 potential "issues" here:
req.params.frameworkId and req.params.domainId come as string type. And I assume the _id field is type ObjectId and not string.
To fix this you just need to cast it to the proper type, like so:
import { ObjectId } from 'mongodb';
...
{ _id: new ObjectId(req.params.frameworkId) }
Both parameters are "querying" the same field (_id), unless this is intentional somehow if these values are different it will never find a document to match, this should be changed.
Lastly if you want to update an existing object if exists, and if not insert then you should use updateOne with the upsert option:
await Framework.updateOne(query, { $push: { domains: control } }, { upsert: true }).exec();
I have 4 level nested schema:
Framework has Domain referenced to it, Domain has control referenced to it, and Control has SubControl referenced to it.
Now I have been searching for a while and I keep getting confused.
First question: is it possible to post all the data from the framework it self?
Second question: I have used referencing with ID approach, should I switch to using subDocuments?
Framework Schema:
const FrameworkSchema = new Schema({
name: {
type: String,
trim: true
},
description: {
type: String,
trim: true
},
domain: [{
domain: {type: Mongoose.Schema.Types.ObjectId, ref: 'Domain'}
}],
updated: Date,
created: {
type: Date,
default: Date.now
}
});
module.exports = Mongoose.model('Framework', FrameworkSchema);
Domain Schema:
const DomainSchema = new Schema({
_id: {
type: Schema.ObjectId,
auto: true
},
domainNo: {
type: String,
trim: true
},
domainName: {
type: String,
trim: true
},
domainDescription: {
type: String,
trim: true
},
framework: {
type: Mongoose.Schema.Types.ObjectId,
ref: 'Framework'
},
control: [{
control: {type: Mongoose.Schema.Types.ObjectId, ref: 'Control'}
}],
updated: Date,
created: {
type: Date,
default: Date.now
}
});
module.exports = Mongoose.model('Domain', DomainSchema);
My control Schema:
const ControlSchema = new Schema({
_id: {
type: Schema.ObjectId,
auto: true
},
mainControl: {
type: String
},
subControl: [{
subControlNo: {type: Mongoose.Schema.Types.String, ref: 'SubControl'}
}],
controlDescription: {
type: String,
trim: true
},
updated: Date,
created: {
type: Date,
default: Date.now
}
});
module.exports = Mongoose.model('Control', ControlSchema);
My SubControl Schema
const SubControlSchema = new Schema({
_id: {
type: Schema.ObjectId,
auto: true
},
subControlNo: {
type: [String]
},
updated: Date,
created: {
type: Date,
default: Date.now
}
});
module.exports = Mongoose.model('SubControl', SubControlSchema);
Now I'm trying to post this nested documents from the framework api:
router.post(
'/add',
auth,
role.checkRole(role.ROLES.Admin), async (req, res) => {
try {
const subControl = new SubControl({...req.body});
const subControlDoc = await subControl.save();
const control = new Control({...req.body}); // take the control data
control.subControl.push(subControlDoc._id); // take the subControl and push the ID into the control
const controlDoc = await control.save();
//make the subcontrol pushed into control
// make control pushed in domain
const domain = new Domain({...req.body});
domain.control.push(controlDoc._id);
const domainDoc = await domain.save();
const framework = new Framework({...req.body});
framework.domain.push(domainDoc._id);
const frameworkDoc = await framework.save(); //save the framework + domain's ID
res.status(200).json({
success: true,
message: `Framework has been added successfully!`,
framework: frameworkDoc
});
} catch (error) {
res.status(400).json({
error
// error: 'Your request could not be processed. Please try again.'
});
}
}
);
Now I'm using push to push the data as an array, not sure if this the right approach, and Is it possible to post the all the data from the framework api?
Tried to post this from postman:
{
"name": "ISO780001",
"description": "frameworkDescription",
"domain":
[
{
"domainNo": "11",
"domainName": "domainName00",
"domainDescription": "domaindescu0",
"control": [{
"mainControl": "1-4",
"subControl": [{
"subControlNo": "1-4-1"
},
{
"subControlNo": "1-4-2"
}],
"controlDescription": "controlDescriptionTest"
},
{
"mainControl": "1-4",
"subControl": [{
"subControlNo": "1-4-1"
},
{
"subControlNo": "1-4-2"
}],
"controlDescription": "controlDescriptionTest"
}
]
},
{
"domainNo": "1-2",
"name": "domainName00",
"description": "domaindescu0",
"control": {
"mainControl": "1-4",
"subControl": [{
"subControlNo": "1-4-1"
},
{
"subControlNo": "1-4-2"
}],
"controlDescription": "controlDescriptionTest"
}
}
]
}
Only the id's of the domain, control, and subControl get saved in mongodb, is this the how it works can I post all the data from one model in this case the framework? or should I use embedded approach ?
What I will do in scenario where i have alot of references (mongoose name it ref by the way, which allows you to populate).
Example of a frameWork schema with domain reference.
const frameworkSchema = mongoose.Schema({
domains: [{type: mongoose.Schema.Types.ObjectId, ref: 'Domain'}],
})
const FrameworkModel = mongoose.model('Framework', frameworkSchema)
Domain above refers to a Domain model. We can create a domain model now.
const domainSchema = mongoose.Schema({
_id: { type: mongoose.Schema.Types.ObjectId } //this is the default
})
const DomainModel = mongoose.model('Domain', domainSchema);
Example Usage - We want to get all the domain information related to a specific schema.
const results = FrameworkModel.findOne({ _id: 'some framework id'}).populate('domains').lean({ virtuals: true });
The results will be something like
{
_id: 'some framework id',
name: 'name of framework',
domains: [
{
_id: 'id of domain 1',
name: 'example.com'
},
{
_id: 'id of domain 2',
name: 'example2.com'
}
]
}
You can also explore virtuals to see how you can maintain your framework, domains and other controls as separate collections, in order to easily reference to them. This is a better design than nesting multiple levels in a single document.
Unless where necessary, using separate collections has more benefits than using subdocuments. (easier to find documents and easier to update documents, and of course, more performant)
I'm trying to have each record attached to a user who created it,
and every user have their records attached.
Here are my schemas:
1.The Records schema:
const mongoose = require('mongoose')
const RecordsSchema = new mongoose.Schema(
{
Title: { type: String, required: true },
postedby:[{
type: mongoose.Schema.Types.ObjectId,
ref: 'user'
}],
Author: { type: String, required: true},
ISBN: { type: String, required: true },
Review: { type: String },
SelectedFile: { type: String },
Likes: { type: Number, default:0},
Date: { type: Date, default: Date.now()}
});
module.exports = Records = mongoose.model('record', RecordsSchema', 'record');`
Here is the The user Schema:
const mongoose = require('mongoose')
const userSchema = new mongoose.Schema(
{
username: { type: String},
email: { type: String, required: true ,unique:true},
records:[{
type: [mongoose.Schema.Types.ObjectId],
ref: 'record' }],
password: { type: String, required: true},
Date: { type: Date, default: Date.now(), immutable: true }
});
module.exports = User = mongoose.model('user', userSchema,'user');
The express route for getting a record:
router.get('/postedby/', (req, res) => {
Records.find(req.params.id)
.populate('postedby')
.exec()
.then(post =>{
if (!post) {
return res.status(400).json({ msg: 'Add Posts' });
}
else return res.json(post);
}).catch (err => console.error(err))
});
Result of the route:
{
"postedby": [],
"Likes": 0,
"_id": "5fed8c12a4fb2c1e98ef09f6",
"Title": "New Age",
"Author": "Situma Prisco",
"ISBN": "23422",
"SelectedFile": "",
"Review": "",
"Date": "2020-12-31T08:30:10.321Z",
"__v": 0
},
I'm getting a blank Array on the populated user field(posteddby) .
Please help, What am I doing wrong? And yes, i do have a User Logged in
You are too close.
In your schema definition, postedby field itself is an array. Hence you can simply define it like :
postedby:[{
type: mongoose.Schema.Types.ObjectId,
ref: 'user'
}]
Make sure that the ObjectID is stored properly in the postedby array.
Also, you are trying to find a single record based on the ID, hence you can use findById(req.params.id) or findOne({_id:req.params.id}) which would return a single document.
I have this document in mongo atlas
_id: 5f8939cbedf74e363c37dd86,
firstname: "Person",
lastname: "Person lastname",
sex: "Masculino",
age: "20",
birthDay: 2020-10-07T00:00:00.000+00:00,
vaccines: Array
0:Object
dose: Array
_id: 5f8939cbedf74e363c37dd87
vaccine:5f7023ad96f7ed21e85be521
createdAt:2020-10-16T06:12:27.726+00:00
updatedAt:2020-10-16T06:12:27.726+00:00
1:Object
dose:Array
_id:5f893a9ca98e97188c93fea8
vaccine:5f70259796f7ed21e85be523
2:Object
dose:Array
_id:5f893acda98e97188c93fea9
vaccine:5f7023ad96f7ed21e85be521
This is my mongoose schema
const mySchema = new Schema({
firstname: {
type: String,
required: true,
},
lastname: {
type: String,
required: true,
},
sex: {
type: String,
required: true,
},
age: {
type: String,
required: true,
},
birthDay: {
type: Date,
required: true,
},
vaccines: [
{
type: new Schema(
{
vaccine: {
type: Schema.ObjectId,
ref: "Vaccine",
},
dose: Array,
},
{ timestamps: true }
),
},
],
});
every time I add a new person the vaccines array gets one new object with the timestamp as you can see, in my js file I use this code:
const addPerson = (person) => {
const myPerson= new Model(person);
return myPerson.save();
};
Then when I add a new vaccine for the same person this does not get the timestamp, I'm using this code for that:
const addPersonVaccine = async ({ params, body }) => {
if (!params) return Promise.reject("Invalid ID");
const vaccines = [body];
const foundPerson = await Model.updateOne(
{
_id: params,
},
{
$push: {
vaccines: vaccines,
},
}
);
return foundPerson;
};
This is what my body inside vaccines array has:
[ { vaccine: '5f72c909594ee82d107bf870', dose: 'Primera' } ]
The problem is that I have no results about the next timestamps, as you can see in my mongo atlas document:
1:Object
dose:Array
_id:5f893a9ca98e97188c93fea8
vaccine:5f70259796f7ed21e85be523
2:Object
dose:Array
_id:5f893acda98e97188c93fea9
vaccine:5f7023ad96f7ed21e85be521
Is that the best way to implement timestamps in subdocuments or sub schemas?
I will appreciate your answers, thnks 👏
You can use mongoose schema timestamps options to the inner schemas
const mongoose = require("mongoose");
const forumSchema = new mongoose.Schema(
{
title: { type: String, required: true },
biddings: [
{
type: new mongoose.Schema(
{
biddingId: String,
biddingPoints: Number
},
{ timestamps: true }
)
}
]
},
{ timestamps: true }
);
const Forum = mongoose.model("Forum", forumSchema);
module.exports = Forum;
for more Mongoose schema set timestamp on nested document
I have two models Vote and Link,I am trying to populate the votes array in link model,The votes array contains id's that references to the collection Vote,which only contains two fields link and User which also refs to same link model mentioned below and a user model respectively
link Schema:-
const linkSchema = new mongoose.Schema(
{
description: {
type: String,
trim: true,
},
url: {
type: String,
trim: true,
},
postedBy: {
type: mongoose.Types.ObjectId,
ref: "User",
},
votes: [{ type: mongoose.Types.ObjectId, ref: "Vote" }],
},
{
timestamps: true,
}
);
linkSchema.index({ description: "text" });
linkSchema.index({ createdAt: -1 });
module.exports = mongoose.model("Link", linkSchema);
Vote schema:-
const mongoose = require("mongoose");
const voteSchema = new mongoose.Schema({
link: { type: mongoose.Types.ObjectId, ref: "Link" },
user: { type: mongoose.Types.ObjectId, ref: "User" },
});
module.exports = mongoose.model("Vote", voteSchema);
but when i try to get the votes of a link,it always return an empty array ,My function:-
const votes = async ({ id }) => {
const linkData = await Link.findById(id).populate("votes").exec();
console.log(linkData);
};
Output Data:-
{
votes: [], //empty always
_id: 5ecb21059a157117c03d4fac,
url: 'https://www.apollographql.com/docs/react/',

}
Instead of populate(), you can use aggregate() to get your desired output. This should probably work in your case:
Link.aggregate([
{
$match: {
_id: { $in: [mongoose.Types.ObjectId(id)] // as suggested by the questioner
}
},
{
$lookup: {
from: "vote", // collection to join
localField: "votes", // field from the input documents (filtered after _id is matched)
foreignField: "link", // field to compare with, from other collection
as: "linkData" // output array name
}
}
])
Let me know in the comments.
