title: Asset Pipeline Where are These Files Coming From
body: <p>My Rails app is getting a couple resources, and I think I want it to ; )</p>
  
  <p>The problem is, I need to understand where they are coming from, but I don't:</p>
  
  <pre><code>7.0.0.1 - - [14/Jan/2018:12:05:33 EST] "GET /assets/jquery-ui/datepicker.css HTTP/1.1" 200 22344
  http://localhost:3000/ -&gt; /assets/jquery-ui/datepicker.css
  127.0.0.1 - - [14/Jan/2018:12:05:33 EST] "GET /assets/jquery.timepicker.css HTTP/1.1" 200 1584
  http://localhost:3000/ -&gt; /assets/jquery.timepicker.css
  </code></pre>
  
  <p>I gather that the assets pipeline is pulling them from somewhere, but I can't figure out from where. There are no files by these names anywhere that I can find in the assets (including vendor) folders or public. Is there a tool other way that I can understand where these are coming from?</p>
