title: Relative Template Import
body: <p>I have a template located in <code>templates/mytemplate.html</code> in my app and I need to reference the template file directly in code to turn it into a string to use with <code>send_mail()</code>. How can I do this? Here's what I've tried:</p>
  
  <pre><code>from django.template import loader
  
  html_message = loader.render_to_string(
              'appname/templates/mytemplate.html',
              {
                  'username': user.name,
              }
          )
  </code></pre>
