title: Ruby on rails link_to an image in assets
body: <p>I'm sure there are many post like this but after to check them I wasn't found anyone to answer my issue.
  Im trying to get an image located at <code>"app/assets/images/levers/I.a.1.png"</code> with a <code>link_to</code> like this:</p>
  
  <p><code>&lt;%= link_to("Biomasa", image_path("levers/I.a.1.png"), :target =&gt; "_new") %&gt;</code></p>
  
  <p>No matter how many times I tried with differents combinations of the path, it doesn't work. I'm getting this error:</p>
  
  <p><code>The asset "levers/I.a.1.png" is not present in the asset pipeline.</code></p>
  
  <p>There are something I'm missing or doing wrong?</p>
  
  <p><strong>More information</strong></p>
  
  <p>I'm not sure if is important but im using "Bash on Ubuntu on Windows" to make all possible from my windows 10 (at work obiously).</p>
