Inserting data to MongoDB from one schema module to another - node.js

Question

I'm using MongoDB with Mongoose, I have to save user data to users collection which contains username, password and company data, *Company data will be having Company name, Address, and website URL
Now what I've done is I've created the different schema for company and users
I need to store user data along with the company ID after installing it into the company collection, for ex.
{
username: "Lorem Ipsum",
password: "Dolar Sit",
company: "5c73afcf9a3bde1a40da5184"
}
something like this (Note: That random string is ID of the company data), but I'll send everything in 1 object like below
{
username: "Lorem Ipsum",
password: "Dolar Sit",
company: {
company_name: "Blah Blah",
company_address: "Blah Blah Blah",
company_website: "BlahBlah.com",
}
}
My user Schema (user.js) is :
const mongoose = require('mongoose');
const Company = require('./company');
Schema = mongoose.Schema
// User Schema
const userSchema = mongoose.Schema({
username:{
type: String,
required: true
},
password:{
type: String,
required: true
},
company:{
type: [{ type: Schema.Types.ObjectId, ref: 'Company' }],
required: true
},
created_on:{
type: Date,
default: Date.now
},
updated_on:{
type: Date,
default: Date.now
}
});
const User = module.exports = mongoose.model('Users', userSchema);
// Add User
module.exports.addUser = (user, callback) => {
User.create(user, callback);
}
And Company Schema is (company.js) :
const mongoose = require('mongoose');
// Book Schema
const companySchema = mongoose.Schema({
company_name:{
type: String
},
target_address:{
type: String
},
target_website:{
type: String
},
created_on:{
type: Date,
default: Date.now
},
updated_on:{
type: Date,
default: Date.now
}
});
const Company = module.exports = mongoose.model('Company', companySchema);
// Add Company
module.exports.addCompany = (comp, callback) => {
Company.create(comp, callback);
}
Now My question is if I run Users.addUser function, and pass the above json to it, it should save/create user along with the company. and company ID should be saved in company property of user collection. if I do get users then it should return User data with company data fetched using that ID saved in the database
How to do that?
If I run the above files and try to insert data to it,
It'll show the below error
'Cast to Array failed for value "{ company_name: \'Moshi Moshi\', company_address: \'Bengaluru\' }" at path "company"',
name: 'CastError',
stringValue:
'"{ company_name: \'Moshi Moshi\', company_address: \'Bengaluru\' }"',
kind: 'Array',
value: [Object],
path: 'company',
reason: [MongooseError] } },
_message: 'Users validation failed',
name: 'ValidationError' }

E:\MoshiMoshi\Projects\Maaamamia\blackhole-rest\models\users.js:17
type: [{ type: ObjectId, ref: 'Company' }],
^
ReferenceError: ObjectId is not defined
how to achive that functionality?

Answer 1

first of all in your user schema company should not be an array because an user will have only single company Id according to your requirement.
//incorrect
company:{
type: [{ type: Schema.Types.ObjectId, ref: 'Company' }],
required: true
},
//correct
company:{
type: Schema.Types.ObjectId,
ref: 'Company',
required: true
},
And second while adding user you are passing entire company object to the company attribute.
first you should add company and then store _id of saved company object into company attribute of user then save user object.
let yourJsonObject={
username: "Lorem Ipsum",
password: "Dolar Sit",
company: {
company_name: "Blah Blah",
company_address: "Blah Blah Blah",
company_website: "BlahBlah.com",
}
}
let companyObject=yourJsonObject.company;//your company object
let userObject= yourJsonObject //your user object
let savedCompanyObject= //call add company method of your
//model with companyObject data
userObject.company = savedCompanyObject._id;
//now pass userObject to your addUser method of user model
