Ruby On Rails won't load assets from app/assets
<p>I'm starting in de Ruby on Rails world (I'm the noobest noob), as far as I know, when I put .css and .js into the app/assets/stylesheets folder and javascripts folder, respectively, it should automatic load those files. But it just doesn't. </p>

<p>I've found this code line</p>

<pre><code>&lt;%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' =&gt; true %&gt;
</code></pre>

<p>But it just renders the application.css into the HTML code.</p>

<p>Is there some setting I'm missing?</p>
