Update Step 4 - Add app_name attribute

Latest django-polls from pip uses the 'polls' namespace to display the poll app. From polls/templates/index.html:

    <li><a href="{% url 'polls:detail' poll.id %}">{{ poll.question }}</a></li>

Unless you set the 'app_name' to 'polls', the example in the tutorial won't work.

I tried to do that but still warning Django NoReverseMatch, u'polls' is not a registered namespace

I could not solve this. :/

If you add the app_name after you already added the plugin to a page, try deleting the page and recreating it, for me that did the trick. If an app_name is specified, you can set the instance name of the app when adding it, if no app_name is set, this option doesn't show up. I assume this is the origin of the problem
