Doesn't create foreign key when defining association

Referencing from an old #2031 , hasOne association does not creating the foreign key, as it intend to do according to hasOne Documentation .

What are you doing?

I was creating an UserModel and UserStatus model. Status like waiting for approval, approved, rejected etc. Association i meant to create like, Every user should have a status. So i put code like this

// UserModel is created using `sequelize.define`
// UserType is created using `sequelize.define`
UserModel.hasOne(UserType, { foreignKey: { allowNull : false }, onDelete: "CASCADE" })

To Reproduce Steps to reproduce the behavior:

1. Define models UserModel, UserType.
2. Run the following
3. See error

What do you expect to happen?

i expect to create a foreign key userTypeId to be created inside the users table.

What is actually happening?

No foreign key association was created in the user table

CREATE TABLE IF NOT EXISTS `users` (`id` INTEGER PRIMARY KEY AUTOINCREMENT, `firstName` VARCHAR(30) NOT NULL, `lastName` VARCHAR(30) NOT NULL, `email` VARCHAR(30) NOT NULL UNIQUE, `password` VARCHAR(255) NOT NULL);
