OptionalvalidateAn 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 is async, the callback should be called with the error text.
Column options for the model schema attributes. Used in Model.init and Sequelize#define, and the Attribute decorator.
