Дошел до последней главы 4го урока http://djbook.ru/rel1.7/intro/tutorial04.html#amend-views *Получаю ошибку такого рода:
Reverse for 'vote' with arguments '('',)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['poll/(?P<question_id>\d+)/vote/$']
<br />
Интересно, что с самописными функциями index, detail, results все работает.<br />
*detail.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Votes detail page</title>

<body>
<h1>{{ question.question_text }}</h1>
{% if error_message %} <p><strong>{{ error_message }}</strong></p> {% endif %}
<form action="{% url 'poll:vote' question.id %}" method="post">
{% csrf_token %}
{% for choise in question.choise_set.all %}
<input type="radio" name="choise" id="choise{{ forloop.counter }}" value="{{ choise.id }}"/>
<label for="choise{{ forloop.counter }}">{{ choise.choise_text }}</label> <br />
{% endfor %}

P.S. В моем приложении названия polls = poll, choice = choise, Question = Questions
