title: Get Sequelize.js ENUM Values from Already Defined Model
body: <p>How do we get the ENUM values of a model after defining it in Sequelize.js?</p>
  
  <p>For example, we define our model as:</p>
  
  <pre><code>sequelize.define('model', {
    states: {
      type:   Sequelize.ENUM,
      values: ['active', 'pending', 'deleted']
    }
  })
  </code></pre>
  
  <p>How do we get the pre-defined <code>['active', 'pending' ,'deleted']</code> values from this model?</p>
