Sequelize Model exports a Function - mysql

Question

i have define this model:
const Sequelize = require('sequelize');
const db = require("../database/db")
var Reparacion = db.sequelize.define('reparaciones', {
id: {
type: Sequelize.INTEGER,
allowNull: false,
autoIncrement: true,
primaryKey: true,
},
descripcion: {
type: Sequelize.STRING(255),
allowNull: true
},
fecha_inicio: {
type: Sequelize.DATEONLY,
allowNull: true
},
fecha_fin: {
type: Sequelize.DATEONLY,
allowNull: true
},
},{});
module.exports=Reparacion
In other model when I define the foreing Key in other model, the methods HasMany and belongsTo doesn't works because I call them on a function:
const Reparacion = require("./reparacion")
console.log(typeof(Vehiculo))
console.log(typeof(Reparacion))
Vehiculo.hasMany(Reparacion,{foreingKey:"vehiculoId", onDelete: 'cascade', sourceKey:"matricula"})
Reparacion.belongsTo(Vehiculo)
The both console log return: "function"
What i have to change for define correctly the association??
EDIT
that is de "Vehiculo" model:
const Sequelize = require('sequelize');
const db = require("../database/db")
var Vehiculo = db.sequelize.define('vehiculos', {
id: {
type: Sequelize.INTEGER,
autoIncrement: true,
primaryKey: true,
allowNull: true
},
matricula: {
type: Sequelize.STRING(45),
allowNull: false,
primaryKey: true,
},
marca: {
type: Sequelize.STRING(50),
allowNull: true
},
modelo: {
type: Sequelize.STRING(50),
allowNull: true
},
anio: {
type: Sequelize.INTEGER,
allowNull: true
},
color: {
type: Sequelize.STRING(20),
allowNull: true
},
puertas: {
type: Sequelize.INTEGER,
allowNull: true
},
motor: {
type: Sequelize.STRING(20),
allowNull: true
},
},{});
const Reparacion = require("./reparacion")
Vehiculo.hasMany(Reparacion,{foreingKey:"vehiculoMatricula", onDelete: 'cascade', sourceKey:"matricula"})
Reparacion.belongsTo(Vehiculo)
module.exports=Vehiculo

Answer 1

Well, it is expected that typeof Vehiculo and typeof Reparacion will return a function that happens because every constructor or class is a function in JS, so when you create a model for an entity it returns a function/constructor that can create an instance of an entity for you. So there is no problem with that.
And actually the documentation shows similar code https://sequelize.org/master/manual/assocs.html
