Class Model

src/model.js:53–4697

* A Model represents a table in the database. Instances of this class represent a database row. * * Model instances operate with the concept of a `dataValues` property, which stores the actual values represented by the instance. * By default, the values from dataValues can also be accessed direct

 * @mixes Hooks
