title: SequelizeJS Soft Deleting
body: <p>I can't figure out how the soft deleting works with SequelizeJS and I cannot find any documentation online.</p>
  
  <p>I've already setup at a <code>deletedAt</code> column as</p>
  
  <pre><code>deletedAt: {
      type: Sequelize.DATE
  }
  </code></pre>
  
  <p>but I don't know how to now setup the system so that <code>MyModel.destroy(query)</code> soft deletes it instead. Currently, it plainly removes the entry completely.</p>
