Association without foreign keys and make join in table - mysql

Question

I am working on Node + sequelize + mysql. All the things is working fine in my code. Now i need to add search field in list page. In this search page there is showing user first name, last name, company name and status. I got all data from one table but company comes from "Company" table. In user table there is company_id. I can not make association for company_id. Now i want to search from company_name too. How i add include without association.
const { User, Company } = require("../models");
if(query.trim() != "") {
[err, users] = await to(User.findAll({
where : {[Op.or] : {first_name:{ [Op.like]: '%'+query.trim()+'%' },last_name:{ [Op.like]: '%'+query.trim()+'%' }}},
include : [
{
model:Company,
where : {company_name:{ [Op.like]: '%'+query.trim()+'%' }}
}],
limit: 5,
offset: 0,
order: [[id, ASC]]
}));
console.log('err ----------------',err);
console.log(users);
}
I got below error on from above code :
err ---------------- { filename:
'/var/www/html/fullproject-name/backend/node_modules/sequelize/lib/model.js',
line: 583,
row: 13,
message: 'Company is not associated to User!',
type: 'SequelizeEagerLoadingError',
stack:
'SequelizeEagerLoadingError: Company is not associated to User!\n at Function._getIncludedAssociation..... }
User Model Code :
module.exports = (sequelize, DataTypes) => {
var Model = sequelize.define('User', {
email: {type: DataTypes.STRING, allowNull: true, unique: true, validate: { isEmail: {msg: "Phone number invalid."} }},
company_id: DataTypes.INTEGER,
first_name: DataTypes.STRING,
last_name: DataTypes.STRING,
active:DataTypes.INTEGER,
});
}
Company Model Code :
module.exports = (sequelize, DataTypes) => {
var Model = sequelize.define('Company', {
company_name: DataTypes.STRING,
company_attachment: DataTypes.STRING,
});
}

You need to associate your models with each other in order to be able to query them together with joins. In the below sample, I added some associations for User and Company. The relation I defined (which you can change) is one to many. A user belongs to one company; a company has many users.
This association will put a foreign key of company_id on the User model.
const models = require("./models.js") // Update if necessary
module.exports = (sequelize, DataTypes) => {
var User = sequelize.define("User", { // Changed from Model to User
email: {
type: DataTypes.STRING,
allowNull: true,
unique: true,
validate: { isEmail: { msg: "Phone number invalid." } }
},
company_id: DataTypes.INTEGER,
first_name: DataTypes.STRING,
last_name: DataTypes.STRING,
active: DataTypes.INTEGER
});
User.belongsTo(models.Company); // User to Company association
};
const models = require("./models.js") // Update if necessary
module.exports = (sequelize, DataTypes) => {
var Company = sequelize.define("Company", { // Changed from Model to Company
company_name: DataTypes.STRING,
company_attachment: DataTypes.STRING
});
Company.hasMany(models.User); // Company to User association
};
