title: call render_template method for a directory outside running app
body: <p>I'm trying to call the render_template method in flask to a template that is outside the current running directory</p>
  
  <pre><code>return render_template('../show_data.html',data=data)
  </code></pre>
  
  <p>You'll notice I tried to use '..' to go back in the directory structure but that is not working as I'm getting a error:</p>
  
  <pre><code>jinja2.exceptions.TemplateNotFound
  </code></pre>
