title: Dashboard doesn't populate values after forking template django-oscars
body: <p>here's my view.py of dashboard-</p>
  <pre><code>from django.views.generic import TemplateView
  class IndexView(TemplateView):
      def get_template_names(self):
      if self.request.user.is_staff:
        return ['mytemplates/index.html']
      else :
        return ['dashboard/index_nonstaff.html','mytemplates/index.html']
  </code></pre>
  <p>So I'm successfully able to fork the app and extend templates but for some reason no values appears on the dashboard</p>
