Knex.js method in bookshelf.js
<p>How to insert <a href="http://knexjs.org/#Builder-increment" rel="nofollow">a increment method</a> like <code>bookshelf.knex('articles').increment('fetchCount', 1)</code> in the code below:  </p>

<pre><code>router.get('/:id', (req, res) =&gt; {
   Article.query({
      where: {id: req.params.id}
   }).fetch().then(article =&gt; {
      res.json(article)
   })
})
</code></pre>

<p>I have a table called 'articles', and I want to increment a value in a fetchCount column before it send json response.  </p>

<p>when I use bookshelf.knex, bookshelf should be my model like Article?</p>
