This tag is equivalent to {% cycle %} but resets when we exit the containing loop. See Django ticket "Cycle tag should reset after it steps out of scope" [https://code.djangoproject.com/ticket/5908](https://code.djangoproject.com/ticket/5908) This code is a lightly modified version of Simon Litchfield's attachment on that ticket.
This is a customized version of the default `for` template tag which takes an optional `{% else %}` clause that will be displayed if the given array is empty. from django.template import * >>> t1 = Template(""" {% load mytags %} {% for athlete in athlete_list %} {{ athlete }} {% else %} No athlete in list! {% endfor %} """) >>> c1 = Context( {'athlete_list': ['me', 'myself', 'I'] }) >>> t1.render(c1) u'me myself I ' >>> c2 = Context({}) >>> t1.render(c2) u'No athlete in list!' If you want to automatically override the builtin `for` template-tag add it to the builtins: from django.template import add_to_builtins add_to_builtins('python.path.to.mytags')
