title: Django App template Loader, can't find app templates
body: <p>I have the following two apps located in my <code>virtualenv</code>: <code>backend</code> <code>backoffice</code>.
  The <code>backoffice</code> app has templates under:</p>
  
  <p><code>backoffice/templates</code></p>
  
  <p>So when I login into the Django shell, I can to do the following:</p>
  
  <pre><code>&gt;&gt;&gt;from django.template.loaders.app_directories import Loader
  &gt;&gt;&gt; list(l.get_template_sources('index.html'))
  [u'/var/www/venv2.7/lib/python2.7/site-packages/django/contrib/auth/templates/index.html', u'/var/www/venv2.7/lib/python2.7/site-packages/backoffice/templates/index.html', u'/var/www/venv2.7/lib/python2.7/site-packages/django/contrib/admin/templates/index.html']
  </code></pre>
  
  <p>So it seems the template is correctly found (<code>l.load_template_source(('index.html')</code> is also working). </p>
  
  <p>However, when I access my home page via the browser I get an error:</p>
  
  <pre><code>TemplateDoesNotExist at /
  </code></pre>
  
  <p>Can someone help me solve the puzzle? What am I missing?</p>
