def board(request):
	boards = Board.objects.all()
	html = 'boards.html'

Pavel Denisov,

<a class="navbar-brand" href="{% url 'board' %}">Django Boards</a>

[xxx]

Pavel Denisov, Невнимательно, не в том шаблоне смотрел вообще.

<a href="{% url 'board_topics' board.pk %}">{{ board.name }}</a>
<a href="{% url 'topic_posts' board.pk %}">
                  By {{ post.created_by.username }} at {{ post.created_at }}
                </a>

Вот эти 2 урла

Pavel Denisov, Вот так

<a href="{% url 'topic_posts' board.pk post.topic.pk %}">
                  By {{ post.created_by.username }} at {{ post.created_at }}
                </a>

Exception Value: 	

Reverse for 'topic_posts' with arguments '(2, '')' not found. 1 pattern(s) tried: ['boards/(?P<pk>\\d+)/topics/(?P<topic_pk>\\d+)/$']

В самый верх подними этот url:

url(r'^boards/$',
      board,
      name='board'
    ),
