The name of the attribute (JS side).

If true, the column will get a unique constraint. If a string is provided, the column will be part of a composite unique index. If multiple columns have the same string, they will be part of the same unique index
An object of validations to execute for this column every time the model is saved. Can be either the
name of a validation provided by validator.js, a validation function provided by extending validator.js
(see the
DAOValidator property for more details), or a custom validation function. Custom validation functions
are called with the value of the field, and can possibly take a second callback argument, to signal that
they are asynchronous. If the validator is sync, it should throw in the case of a failed validation, it
it is async, the callback should be called with the error text.
Usage in object notation
class MyModel extends Model {}
MyModel.init({
states: {
type: DataTypes.ENUM,
values: ['active', 'pending', 'deleted']
}
}, { sequelize })
