i have json data like below:
{"ModelId":"m1","AddCompleted":[{"UniqueId":"c1"}, {"UniqueId":"c2"}],"AddActive":[{"UniqueId":"a1"}],"AddPlanned":[{"UniqueId":"p1"}]}
do i have to use nested/sub-schema like below:
const mySchema = new mongoose.Schema({
ModelId: { type: string, unique: true, required: true },
AddCompleted: [ new Schema({ UniqueId: string }), { _id: false } ],
AddActive: [ new Schema({ UniqueId: string }), { _id: false } ],
AddPlanned: [ new Schema({ UniqueId: string }, { _id: false }) ],
});
or can simply use:
const mySchema = new mongoose.Schema({
ModelId: { type: string, unique: true, required: true },
AddCompleted: [ { type: string } ],
AddActive: [ { type: string } ],
AddPlanned: [ { type: string } ],
});

I have two schemas user and note-
user schema
import mongoose from 'mongoose';
const userSchema = mongoose.Schema({
id: {
type: String,
},
name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
unique: true,
},
password: {
type: String,
required: true,
},
notes: [
{
type: mongoose.Types.ObjectId,
ref: 'Note',
},
],
folders: {
type: [
{
name: {
type: String,
},
notes: [
{
type: mongoose.Types.ObjectId,
ref: 'Note',
},
],
},
],
default: [
{ name: 'My Notes', notes: [] },
{ name: 'Todos', notes: [] },
{ name: 'Projects', notes: [] },
{ name: 'Journals', notes: [] },
{ name: 'Reading list', notes: [] },
],
},
});
const User = mongoose.model('User', userSchema);
export default User;
note schema
import mongoose from 'mongoose';
const noteSchema = new mongoose.Schema({
id: {
type: String,
required: true,
},
modify_date: {
type: String,
required: true,
},
modify_time: {
type: String,
required: true,
},
tags: [
{
id: {
type: String,
required: true,
},
text: {
type: String,
required: true,
},
},
],
created_by: {
type: mongoose.Types.ObjectId,
ref: 'User',
required: true,
},
folder: {
type: String, //can I use ref from user?
},
title: {
type: String,
},
body: {
type: String,
required: true,
},
time_stamp: {
type: Date,
required: true,
},
});
const Note = mongoose.model('Note', noteSchema);
export default Note;
I have searched but could not find anything. I want to use the nested folder object from user schema as a ref in note schema; so, whenever I change or update a folders name all the notes get the updated value. Is it possible?
If not should I make a separate folder schema and add ref of folder schema in both note and user? How can I achieve that, any suggestion might be very helpful?
my model schema look like this
const mongoose = require("mongoose")
const userSchema = new mongoose.Schema(
{
username: {
type: String,
required: true,
},
password: {
type: String,
required: true,
select: false,
},
email: {
type: String,
required: true,
unique: true,
match: [
/^\w+([\.-]?\w+)*#\w+([\.-]?\w+)*(\.\w{2,3})+$/,
"Please enter a valid email",
],
},
followers:[
{
type:mongoose.Schema.Types.ObjectId,
ref:"user"
}
],
following:[
{
type:mongoose.Schema.Types.ObjectId,
ref:"user"
}
],
displayName: {
type: String,
required: false,
},
},
{ timestamps: true }
)
module.exports = mongoose.model("user", userSchema)
in this schema all working good like mutation work fine but when i fetch query of all user then in that query followers and following field return null like bellow image
and my graphql query is
const users = {
type: new GraphQLList(UserType),
description: "Retrieves list of users",
resolve(parent, args) {
return User.find()
},
}
and typedef is
const UserType = new GraphQLObjectType({
name: "User",
description: "User types",
fields: () => ({
id: { type: GraphQLID },
username: { type: GraphQLString },
email: { type: GraphQLString },
post:{
type: GraphQLList(PostType),
resolve(parent, args) {
return Post.find({ authorId: parent.id })
},
},
savePost:{
type:GraphQLList(savedPosts1),
resolve(parent, args) {
return SavePost.findById({ authorId: parent.id })
},
},
followers:{
type:GraphQLList(UserType),
},
following:{
type:GraphQLList(UserType)
}
// displayName: { type: GraphQLString },
}),
})
so please tell me how to i resolve that followers and following query in graphql with mongodb and tell me what i write in my userType typedef
How to fetch data from multiple collections in MongoDB by using a common field and sending data (in those fetched collections) using one response?
Employee Scheema:
const mongoose = require("mongoose");
const employeeSchema = new mongoose.Schema(
{
profilePic: {
type: String,
},
employeeID: {
type: String,
required: true,
},
employeeFirstName: {
type: String,
required: true,
},
employeeLastName: {
type: String,
required: true,
},
birthday: {
type: String,
},
streetNo: {
type: String,
},
city: {
type: String,
},
phoneNumber: {
type: String,
},
jobRole: {
type: String,
required: true,
},
NIC: {
type: String,
required: true,
unique: true,
},
companyEmail: {
type: String,
required: true,
unique: true,
},
status: {
type: String,
required: true,
},
resignDate: {
type: String,
},
jobType: {
type: String,
required: true,
},
candidateID: {
type: String,
required: true,
},
teamID: {
type: String,
},
lastSeen: {
type: String,
},
token: {
type: String,
},
},
{ timestamps: true }
);
module.exports = mongoose.model("employee", employeeSchema);
Acadamic Qualification Scheema:
const mongoose = require("mongoose");
const academicQualificaationSchema = new mongoose.Schema(
{
employeeID: {
type: String,
required: true,
},
ordinaryLevelResult: {
type: Array,
required: true,
},
advancedLevelResults: {
type: Array,
required: true,
},
achievements: {
type: Array,
required: true,
},
},
{ timestamps: true }
);
module.exports = mongoose.model(
"academicQualification",
academicQualificaationSchema
);
Professional Qualification Scheema:
const mongoose = require("mongoose");
const proffesionalQualificaationSchema = new mongoose.Schema(
{
employeeID: {
type: String,
required: true,
},
degree: {
type: Array,
required: true,
},
language: {
type: Array,
required: true,
},
course: {
type: Array,
required: true,
},
},
{ timestamps: true }
);
module.exports = mongoose.model(
"proffesionalQualification",
proffesionalQualificaationSchema
);
Controller:
exports.viewEmployees = async (req, res) => {
try {
let accQuali, profQuali;
const employees = await employeeSchema.find();
accQuali = await academicQualificaationSchema.find();
profQuali = await ProffesionalQualificationSchema.find();
if (employees || accQuali || profQuali) {
return res.status(200).json({ data: { employees, profQuali, accQuali } });
} else {
return res.status(404).json({ message: message });
}
} catch (err) {
return res.status(404).json({ err: err.message });
}
};
This controller is working properly and sends all data in 3 collections with the use of one response. But, I am comfortable if I will be able to Fetch data separately for each employee.
If you want to get the data from the three collections for specific employee or employees, you can use an aggregation pipeline with a $lookup stage, as suggested by #1sina1. For example:
db.employee.aggregate([
{
$match: {"employeeID": "IDA"}
},
{
$lookup: {
from: "academicQualification",
localField: "employeeID",
foreignField: "employeeID",
as: "academicQualification"
}
},
{
$lookup: {
from: "proffesionalQualification",
localField: "employeeID",
foreignField: "employeeID",
as: "proffesionalQualification"
}
}
])
As you can see on the playground
I am trying to obtain data from mongodb. This is the scenario. Each user has a following property(array) that takes an array of users id.
The user model is as below
const userSchema = new mongoose.Schema({
name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
},
password: {
type: String,
required: true,
},
followers: [{ type: mongoose.Types.ObjectId, ref: "user" }],
following: [{ type: mongoose.Types.ObjectId, ref: "user" }],
});
in simple terms. I need to use two conditions where postedBy: { $in: req.user.following }, or postedBy:req.user._id
const postSchema = new mongoose.Schema({
title: {
type: String,
required: true,
},
body: {
type: String,
required: true,
},
photo: {
type: String,
required: true,
},
likes: [{ type: mongoose.Schema.ObjectId, ref: "user" }],
comments: [
{
text: String,
postedBy: { type: mongoose.Schema.Types.ObjectId, ref: "user" },
},
],
postedBy: {
type: mongoose.Schema.Types.ObjectId,
ref: "user",
},
});
I have not figured out the second condition to add in the code below.
router.get("/getSubPost", requireLogin, async (req, res) => {
try {
const result = await Post.find({
postedBy: { $in: req.user.following },
})
.populate("postedBy", "-password")
.populate("comments.postedBy", "_id name");
res.json({ result });
} catch (error) {
console.log(error);
}
});
I am trying to make an api with express.js and mongoDB (using mongoose) and don't know how to properly add an item to my existing array (nextUp). For example I have an existing User in my database with templates: { issues: { nextUp: [], inProgress: [], completed: [] } } and want to add e.g. {issueName: 'MyName', issueDate: '20/5/2020'} to nextUp field.
const mongoose = require('mongoose');
const { Schema } = mongoose;
const UserSchema = new Schema({
username: {
type: String,
required: true,
unique: true,
minlength: 3,
sparse: true,
},
email: {
type: String,
required: true,
unique: true,
minlength: 5,
maxlength: 255,
sparse: true,
},
password: {
type: String,
required: true,
minlength: 8,
sparse: true,
},
newsletterSubscribed: {
type: Boolean,
},
termsAndPolicyAgreement: {
type: Boolean,
required: true,
},
templates: {
title: {
type: String,
},
description: {
type: String,
},
issues: {
nextUp: [
{
issueName: {
type: String,
},
issueDate: {
type: String,
},
},
],
inProgress: [
{
issueName: {
type: String,
},
issueDate: {
type: String,
},
},
],
completed: [
{
issueName: {
type: String,
},
issueDate: {
type: String,
},
},
],
},
},
});
const UserModel = mongoose.model('user', UserSchema);
module.exports = UserModel;
I've tried to do that but my item hasn't added. (username Kacper exists there is no problem with that).
UserModel.findOneAndUpdate(
{ username: 'Kacper' },
{
$push: {
nextUp: [
{
issueName: 'MY NEW ISSUE',
issueDate: 'MY ISSUE DATE',
},
],
},
},
);
