Hi I want to implement this snippet of my class diagram using mongoose.
Here is my logic model in detail:
Here is the definition of my Mother model:
const mongoose = require('mongoose')
const motherSchema = mongoose.Schema({
cniMother: { type: Number, required: true },
name: { type: String, required: true },
surname: { type: String, required: true },
birthDay: { type: Date, required: true },
birthPlace: { type: String, required: true },
address: { type: String, required: true },
phone: { type: Number, required: true },
occupation: { type: String, required: true },
});
module.exports = mongoose.model('Mother', motherSchema);
Here is the definition of my Declared model:
const mongoose = require('mongoose')
const declaredSchema = mongoose.Schema({
name: { type: String, required: true },
surname: { type: String, required: true },
father: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Father',
//required: true,
},
mother: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Mother',
//required: true,
},
birthDay: { type: Date, required: true },
birthPlace: { type: String, required: true },
gender: { type: String, required: true },
nationality: { type: String, required: true }
});
module.exports = mongoose.model('Declared', declaredSchema);
I want to retrieve the name of the father and the mother corresponding to the declared.
Can anyone help me please?

I need a code in Express.Js and Mongodb where I can change an exact string inside an object through the id of the item, I need to change the string "colorSelected" to a new value, changing only what I put in the body, in my previous failed attempts every change I made would change the entire object, I don't want that, thank you in advance.
Router Cart.js
//update color cart
router.patch("/cart/:id", Auth, async (req, res) => {
});
Model Cart.js
const mongoose = require('mongoose')
const ObjectID = mongoose.Schema.Types.ObjectId
const cartSchema = new mongoose.Schema({
owner : {
type: ObjectID,
required: true,
ref: 'User'
},

I'm using mongoose to to define 2 schemas.
employee.js
const mongoose = require("mongoose");
const uniqueValidator = require("mongoose-unique-validator");
const Role = require("./role");
const employeeSchema = mongoose.Schema({
code: { type: String, required: true, unique: true, index: true },
names: { type: String, required: true },
last_names: { type: String, required: true },
role: Role.schema,
dui: { type: String, required: true, unique: true, index: true },
nit: { type: String, required: false, unique: true, index: true },
sex: { type: String, required: false },
civil_status: { type: String, required: false },
birthday: { type: Date, required: false },
telephone: { type: String, required: true },
city: { type: String, required: true },
address: { type: String, required: true },
active: { type: Boolean, required: true },
});
employeeSchema.plugin(uniqueValidator);
module.exports = mongoose.model("Employee", employeeSchema);
and role.js
const mongoose = require("mongoose");
const uniqueValidator = require("mongoose-unique-validator");
const roleSchema = mongoose.Schema({
code: { type: String, required: true, unique: true, index: true },
description: { type: String, required: true }
});
roleSchema.plugin(uniqueValidator);
module.exports = mongoose.model("Role", roleSchema);
The problem I have is that, whenever I insert a document with a role code that's repeated I get an error because of the unique validation. I have tried deleting
roleSchema.plugin(uniqueValidator);
from role.js and I have also tried using .set to alter the field in role.
const mongoose = require("mongoose");
const uniqueValidator = require("mongoose-unique-validator");
const Role = require("./role");
const subRole = Role.schema.clone().set('code', {unique: false}).set('code', {index : false});
const employeeSchema = mongoose.Schema({
code: { type: String, required: true, unique: true, index: true },
names: { type: String, required: true },
last_names: { type: String, required: true },
role: subRole,
dui: { type: String, required: true, unique: true, index: true },
nit: { type: String, required: false, unique: true, index: true },
sex: { type: String, required: false },
civil_status: { type: String, required: false },
birthday: { type: Date, required: false },
telephone: { type: String, required: true },
city: { type: String, required: true },
address: { type: String, required: true },
active: { type: Boolean, required: true },
});
employeeSchema.plugin(uniqueValidator);
module.exports = mongoose.model("Employee", employeeSchema);
I always get an error saying that role code needs to be unique. Am I using .set incorrectly? or what am I missing? Thank you very much in advance.
Solved it changing:
const subRole = Role.schema.clone().set('code', {unique: false}).set('code', `{index : false});`
to
const subRole = Role.schema.clone().set('excludeIndexes', true);
Deleted the employees's collection so it would recreate it with the right indexes and that did the trick.
It was mentioned in one of mongoose's issues in github:
https://github.com/Automattic/mongoose/issues/11547
Supposedly they implemented something about it but I didn't get it. The above worked for me though.
I tried to join three documents in mongodb using mongoose in nodejs, but unfortunately this error occurs. My mongoose version is 6.2.3
Declaring Schema
const mongoose = require('mongoose')
const declaringSchema = mongoose.Schema({
cniDeclaring: { type: Number, required: true },
father: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Father',
required: true,
},
mother: {
type: mongoose.Schema.Types.ObjectId,

address: { type: String, required: true },
relationShipDeclared: { type: String, required: true },
phone: { type: Number, required: true },
request: [{
type: mongoose.Schema.Types.ObjectId,
ref: 'Request',

});
module.exports = mongoose.model('Declaring', declaringSchema);
Declared Schema
const mongoose = require('mongoose')
const declaredSchema = mongoose.Schema({
name: { type: String, required: true },
surname: { type: String, required: true },
father: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Father',
},
mother: {
type: mongoose.Schema.Types.ObjectId,

});
module.exports = mongoose.model('Declared', declaredSchema);
Father Schema
const mongoose = require('mongoose')
const fatherSchema = mongoose.Schema({
cniFather: { type: Number, required: true },
nameP: { type: String, required: true },
surname: { type: String, required: true },
birthDay: { type: Date, required: true },

ref: 'Declaring',
}],
declared: [{
type: mongoose.Schema.Types.ObjectId,
ref: 'Declared',
}],
});
module.exports = mongoose.model('Father', fatherSchema);
Now I want to get all the fathers back
const Father = require('../models/Father');
exports.createFather = (req, res, next) => {
const father = new Father({
...req.body
});
father.save()
.then(() => res.status(201).json({ message: 'Father created !'}))
.catch(error => res.status(400).json({ error })
);
}
exports.getAllFathers = (req, res, next) => {
Father.find()
.populate('declarings')
.populate('declareds')
.exec((err, res) => {
if(err){
console.log(err);
}
});
};
and I have the following error:
MongooseError: Cannot populate path declarings because it is not in your schema. Set the strictPopulate option to false to override.
Here is my orders schema with Javascript mongoose;
import mongoose from 'mongoose';
const orderSchema = new mongoose.Schema(

image: { type: String, required: true },
price: { type: Number, required: true },
product: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Product',
required: true,
},
},
],
shippingAddress: {
fullName: { type: String, required: true },
address: { type: String, required: true },
city: { type: String, required: true },
postalCode: { type: String, required: true },
country: { type: String, required: true },
lat: Number,
lng: Number,
},
paymentMethod: { type: String, required: true },

update_time: String,
email_address: String,
},
itemsPrice: { type: Number, required: true },
shippingPrice: { type: Number, required: true },
taxPrice: { type: Number, required: true },
totalPrice: { type: Number, required: true },
user: { type: mongoose.Schema.Types.ObjectId, ref: 'User', required: true },
seller: { type: mongoose.Schema.Types.ObjectID, ref: 'User' },
isPaid: { type: Boolean, default: false },

isDelivered: { type: Boolean, default: false },
deliveredAt: { type: Date },
},
{
timestamps: true,
}
);
const Order = mongoose.model('Order', orderSchema);
export default Order;
And for the case of sellers how could I do the same for specific sellers.
I would like to create charts and graphs with that data so any help counts. Thank You!

exports.EacEvent = mongoose.model("EacEvent", scheme);
i need to find all the EacEvents where user _id is equal to some thing like this (56a8a1eaf7a3289c10c9ed30) i have tried many things but either i am getting all the EacEvents or no EacEvent. thanks
Route File
here is my route file code which i am using to get the required results..
var models = require('../models')
,mongoose = require('mongoose')
var schema = mongoose.Schema;
var ObjectId = schema.ObjectId;
// var ObjectID = schema.ObjectId;
exports.myeventapps = function (req, res) {
var eac_userid;
if (req.user){
eac_userid = JSON.stringify(req.user._id);
console.log('================================' + eac_userid);
}
//models.EacEvent.find().exec(function(err, myevents) {
models.EacEvent.find({ deleted: false,'user._id':ObjectId(eac_userid)}).sort({ modified: -1 }).exec(function(err, myevents) {
res.locals.myevents = myevents;
console.log('================================' + myevents);
res.render('eac_myevent_apps', { title: "My Event Apps", myeventapps: myevents });
});
}
i have also tried comparing user._id in .populate() function but did not get the required results
Please try it, match user field directly, rather than user._id.
Refer to Mongoose Populate.
models.EacEvent.find({ deleted: false, 'user': ObjectId(eac_userid)}).sort(...
Maybe we can use the req.user._id directly
models.EacEvent.find({ deleted: false, 'user': req.user._id}).sort(...
