I am creating multi vendor ecommerce platform, with the following schema.
var user = new Schema(
{
uid: { type: String, index: true, unique: true },
firstName: { type: String, required: true, default: null },
lastName: { type: String, default: null, default: null },
userEmail: { type: String, unique: true, required: true, lowercase: true, },
userProfileImg: { type: String, required: true, default: null },
userDesignation: { type: String, default: null },
userMobile: { type: Number, required: true, default: null },
products: { type: Schema.Types.ObjectId, ref: 'Product' },
}
);
var product = new Schema(
{
sku: { type: String, required: true, unique: true },
title: { type: String, required: true },
category: { type: Array, default: [] },
images: { type: Array, default: [], },
groups: { type: Array, default: [], },
price: { type: Number, default: null, },
unit: { type: String, default: null, },
quantity: { type: Number, default: null, },
description: { type: String, default: null, },
},
);
var AllUser = mongoose.model('User', user, 'AllUsers');
var Allproducts = mongoose.model('Product', product, 'AllProducts');
how can i save multiple products while referring to multiple users? Later i want to populate products based on the users.
Your problem is in referencing the collection. In here when you compile your models
var AllUser = mongoose.model('User', user, 'AllUsers');
var Allproducts = mongoose.model('Product', product, 'AllProducts');
you use Product and for database collection you use AllProducts. That's the problem so...try doing it like this
var Users = mongoose.model('Users', user, 'Users');
var Products = mongoose.model('Products', product, 'Products');
Give it a proper naming convention.
Also there is s typo here in this code.. here I have fixed it
var product = new Schema(
{
sku: { type: String, required: true, unique: true },
title: { type: String, required: true },
category: { type: Array, default: [] },
images: { type: Array, default: [] },
groups: { type: Array, default: [] },
price: { type: Number, default: null },
unit: { type: String, default: null },
quantity: { type: Number, default: null },
description: { type: String, default: null}
}
);
also in your user schema
var user = new Schema(
{
uid: { type: String, index: true, unique: true },
firstName: { type: String, required: true, default: null },
lastName: { type: String, default: null, default: null },
userEmail: { type: String, unique: true, required: true, lowercase: true,
},
userProfileImg: { type: String, required: true, default: null },
userDesignation: { type: String, default: null },
userMobile: { type: Number, required: true, default: null },
products: [{ type: Schema.Types.ObjectId, ref: 'Product' }]
}
);
make products as an array type so that you can store multiple product ids

Been pulling my hair out for hours now, just can't figure out why the field refuses to populate.
What I want to do is return the AddressId field populated with values instead of just an ID, but nothing I've tried works, none of the solutions I found do anything.
If you need any other code from the project, I will update the question.
Any help is highly appreciated.
Order Model:
const mongoose = require("mongoose");
const orderSchema = new mongoose.Schema(
{
user: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
required: true,
},
addressId: {
type: mongoose.Schema.Types.ObjectId,
ref: "UserAddress.address",
required: true,
},
totalAmount: {
type: Number,
required: true,
},
items: [
{
productId: {
type: mongoose.Schema.Types.ObjectId,
ref: "Product",
},
payablePrice: {
type: Number,
required: true,
},
purchasedQty: {
type: Number,
required: true,
},
},
],
paymentStatus: {
type: String,
enum: ["Pending", "Completed", "Cancelled", "Refund"],
required: true,
},
paymentType: {
type: String,
enum: ["CoD", "Card", "Wire"],
required: true,
},
orderStatus: [
{
type: {
type: String,
enum: ["Ordered", "Packed", "Shipped", "Delivered"],
default: "Ordered",
},
date: {
type: Date,
},
isCompleted: {
type: Boolean,
default: false,
},
},
],
},
{ timestamps: true }
);
module.exports = mongoose.model("Order", orderSchema);
Address Model:
const mongoose = require("mongoose");
const addressSchema = new mongoose.Schema({
name: {
type: String,
required: true,
trim: true,
min: 10,
max: 60,
},
mobileNumber: {
type: String,
required: true,
trim: true,
},
pinCode: {
type: String,
required: true,
trim: true,
},
locality: {
type: String,
required: true,
trim: true,
min: 10,
max: 100,
},
address: {
type: String,
required: true,
trim: true,
min: 10,
max: 100,
},
cityDistrictTown: {
type: String,
required: true,
trim: true,
},
state: {
type: String,
required: true,
required: true,
},
landmark: {
type: String,
min: 10,
max: 100,
},
alternatePhone: {
type: String,
},
addressType: {
type: String,
required: true,
enum: ["home", "work"],
required: true,
},
});
const userAddressSchema = new mongoose.Schema(
{
user: {
type: mongoose.Schema.Types.ObjectId,
required: true,
ref: "User",
},
address: [addressSchema],
},
{ timestamps: true }
);
mongoose.model("Address", addressSchema);
module.exports = mongoose.model("UserAddress", userAddressSchema);
Code that runs the query:
const Order = require("../models/order");
const Cart = require("../models/cart");
const Address = require("../models/address");
const Product = require("../models/product");
exports.getOrders = (req, res) => {
Order.find({ user: req.user._id })
.select("_id paymentStatus paymentType orderStatus items addressId")
.populate("items.productId", "_id name productImages")
.populate("addressId")
.exec((error, orders) => {
if (error) {console.log(error)
return res.status(400).json({ error });}
if (orders) {
res.status(200).json({ orders });
}
});
};
I want to store an array of nested subdocuments such as the one down bellow:
[
{"2021-02-01income":{"value":37.95,"tax":0,"type":"income"}},
{"2021-03-01income":{"value":38.25,"tax":0,"type":"income"}},
{"2021-03-08fund": {"value":-78,"type":"fund","transaction":"610378deead56742a898443b"}},
{"2021-04-01income":{"value":38.53,"tax":0,"type":"income"}},
{"2021-07-01income":{"type":"income","tax":0,"value":134}},
]
I came up with the following schema which is not working, because as you can see the array of objects is based on unique keys nested objects...
Is there any workaround I can try:
const incomeSchema = mongoose.Schema({
type: { type: String, required: true },
value: { type: Number, required: true },
tax: { type: Number, required: false },
transaction: {
type: mongoose.Schema.Types.ObjectId,
required: false,
ref: 'Transaction',
},
});
const investmentSchema = mongoose.Schema(
{
incomes: [{ type: incomeSchema }],
name: { type: String, required: true },
user: {
type: mongoose.Schema.Types.ObjectId,
required: false,
ref: 'User',
},
account: {
type: mongoose.Schema.Types.ObjectId,
required: true,
ref: 'Account',
},
broker: {
type: mongoose.Schema.Types.ObjectId,
required: true,
ref: 'Broker',
},
type: { type: String, required: true },
rate: { type: String, required: true },
indexer: { type: String, required: true },
investment_date: { type: Date, required: true },
due_date: { type: Date, required: true },
initial_amount: { type: Number, required: true },
accrued_income: { type: Number, required: false, default: 0 },
taxes: { type: Number, required: false, default: 0 },
},
{ timestamps: true }
);
const Investment = mongoose.model('Investment', investmentSchema);
I found a workaround.... I just setted the _id in the Transaction schema as string and now everything is working... I mean I can update the array of neste subdocuments
I need help with mongo, I need to make a query resulting in a objext and many object nested resulting of a one to many relation ship of these schemas:
const ProductSchema = new Schema({
name: { type: String, required: true, unique:true },
picture: { type: String },
description: { type: String, required: true },
isEnabled: { type: Boolean, required: true },
brand: { type: Schema.Types.ObjectId, ref:'Brand' },
slug: { type: String, required: true },
category: { type: mongoose.Schema.Types.ObjectId, ref:'Category' },
reviews: [{ type: mongoose.Schema.Types.ObjectId, ref:'Review' }]
const PackageSchema = new Schema({
type: { type: String, enum:["WEIGHT", "EACH"], required: true },
value: { type: Number, required: true },
price: { type: Number, required: true },
stock: { type: Boolean, required: true},
description: { type: String, required: true},
product: { type: mongoose.Schema.Types.ObjectId, ref:'Product', required: true },
dispensary: { type: mongoose.Schema.Types.ObjectId, ref:'Dispensary', required: true }
This is the code i made
const dispensaryID;
payload = _thisModel.aggregate([
{
$lookup:{
from: "packages",
localField:'_id',
foreignField:'product',
as:"package"
}
},
{"$unwind": {path:"$package", preserveNullAndEmptyArrays: true}} ,
{
$group:
{
_id:"$_id",
number: {
$sum: "$package"
},
package: {$push: '$package'},
}
},
],(aggErr, aggResult) => {
(aggErr) ? console.log(aggResult)
: console.log(aggResult)
})
Buy it is resulting on this:
{ _id: 5ebf98724ef6e503ccd7ae4f, clicks: 0, package: [ [Object] ] },
{
_id: 5ebf98614ef6e503ccd7ae4e,
clicks: 0,
package: [ [Object], [Object], [Object], [Object] ]
},
{ _id: 5ebed37b52ec0043fca22893, clicks: 0, package: [] }
So i need to unbind those objects, I need to see the packages details instead some "[Object]", I tried reconfiguring the script but this is the nearest result I got, also I need to check if a dispensary: { type: mongoose.Schema.Types.ObjectId, ref:'Dispensary', required: true } given in the second schema exists in any of those packages, I will give a const to check if it maches, and add a prop says exists: true on the product object or only delete the whole product object with the packages.
Thanks for the help
I have a mongoose document that has timestamps option enabled. I want to make decisions based on this timestamps but I noticed something weird according to my understanding.
I tried to get those values the traditional way (document.createdAt) but that returns undefined. But if I use document.get('createdAt') the value comes as in the database. The docs don't say anything about this. My question is: ¿Why timestamps behave this way?
Edit
The schema I'm using has an array of embedded schemas:
const Customer = new mongoose.Schema({
roles: {
type: [{
type: String,
enum: 'app b2b iot'.split(' '),
}],
default: 'app',
set: (value = []) => (value.includes('app')
? value
: value.concat('app')),
},
email: {
address: {
type: String,
trim: true,
lowercase: true,
set(email) {
this._previousEmail = this.email.address
return email
},
},
verified: {
type: Boolean,
},
token: String,
},
nickname: {
type: String,
trim: true,
},
recoveryToken: String,
gender: String,
birthday: String,
lastLogin: Date,
isAnonymous: {
type: Boolean,
default: false,
},
devices: [Device],
});
Device schema:
const Device = new mongoose.Schema({
customer: {
type: ObjectId,
ref: 'Customer',
required: true,
},
handle: {
type: String,
},
platform: {
type: String,
required: true,
set: toLowerCase,
},
info: Mixed,
smartFilterTags: [{
type: String,
}],
paidUntil: Date,
nh: {
tier: String,
_id: {
type: ObjectId,
},
location: {
type: {
type: String,
enum: ['Point'],
default: 'Point',
},
coordinates: [{
type: Number,
}],
},
})
I have a base plugin that apply when I compile models:
function basePlugin(schema) {
schema.add({
archivedAt: Date,
})
schema.set('timestamps', true)
schema.set('toJSON', {
virtuals: true,
})
schema.set('toObject', {
virtuals: true,
})
}
This is my Table Collection:
const tableSchema = new Schema({
number: {
type: Number,
required: true,
unique: true
},
seats: {
type: Number,
required: true
},
reservations: [orderSchema]
})
const Table = mongoose.model('Table', tableSchema)
And OrderSchema:
const orderSchema = new Schema({
time: {
type: String,
required: true
},
date: {
type: String
},
user: userSchema
})
And User Collection and Schema:
const userSchema = new Schema({
firstname: {
type: String,
required: true
},
lastname: {
type: String,
required: true
},
email: {
type: String,
required: true,
unique: true
},
phone: {
type: String
},
password: {
type: String,
required: true
},
admin: {
type: Boolean,
default: false,
required: true
}
})
const User = mongoose.model('User', userSchema)
When i would like to create the second (i have no idea why first is adding) instance of table, i am getting error like in title:
MongoError: E11000 duplicate key error collection: restauracja.tables index: reservations.user.email_1 dup key: { : null }
I can create only one document in table, but i have different values in the second one.
