title: Why are wicked_pdf asset helpers generating errors on Heroku
body: <p>I'm using wicked_pdf in a Rails 4.1 app.</p>
  
  <p>PDF generation works perfectly within my local dev setup. But I get errors when deployed to Heroku.</p>
  
  <p>Checking the logs I see </p>
  
  <pre><code>ActionView::Template::Error (No such file or directory - /app/public/photos/application.js):
  </code></pre>
  
  <p>associated with the wicked_pdf helpers</p>
  
  <pre><code>&lt;%= wicked_pdf_javascript_include_tag "application" %&gt;
  </code></pre>
  
  <ol>
  <li>I understood that the wicked_pdf helpers generated absolute urls, so
  why am I seeing a relate url originating from the app folder?</li>
  <li>How is this path being generated? I have no public/photos folder in
  my app!</li>
  <li>How do I go about debugging this problem? I'm unsure if this is a Heroku issue, a wkhtmltopdf issue, an asset compilation issue, or...?</li>
  </ol>
  
  <p>Is anyone using wicked_pdf successfully on Heroku?</p>
