Using a model form

Hi there,

In my file quiz_form.html, there is a block {{ block.super }}, that generates an error:

NoReverseMatch at /courses/1/create_quiz/ Reverse for 'detail' with keyword arguments '{'pk': ''}' not found. 1 pattern(s) tried: ['courses\/(?P<pk>[0-9]+)\/$']

Here is the code below. There are layout.html (project directory):

<!doctype html>
{% load static from staticfiles %}
{% load course_extras %}
<html class="no-js" lang="en">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>{% block title %}{% endblock %}</title>
        <link rel="stylesheet" href="{% static 'css/foundation.min.css' %}">
        <link rel="stylesheet" href="{% static 'css/layout.css' %}">
        {% block css %}{% endblock %}
        <script src="{% static 'js/vendor/modernizr.js' %}"></script>
        <meta class="foundation-mq">
    </head>
    <body>
        <nav class="top-bar" role="navigation">
            <section class="top-bar-left">
                <ul class="dropdown menu" data-dropdown-menu role="menubar">
                    <li class="menu-text">The Learning Site</li>
                    <li class="has-submenu">
                        <a href="#">Courses</a>
                        <ul class="submenu menu vertical" data-submenu role="menu">
                            {% nav_courses_list %}
                            <li><a href="{% url 'courses:list' %}">See all &rarr;</a></li>
                        </ul>
                    </li>
                </ul>
            </section>
        </nav>
        {% if messages %}
            <div class="row">
                <div class="small-6 small-centered columns">
                    {% for message in messages %}
                        <div data-alert class="callout {{ message.tags }}">
                            {{ message }}
                            <a href="#" class="close">&times;</a>
                        </div>
                    {% endfor %}
                </div>
            </div>
        {% endif %}
        {% block content %}{% endblock %}
        <footer class="row columns">
            <hr/>
            <div class="small-6 columns">
                <p>&copy; The Learning Site</p>
            </div>
            <div class="small-6 columns">
                <ul class="inline-list no-bullet float-right">
                    <li><a href="{% url 'courses:list' %}">Courses</a></li>
                </ul>
            </div>
        </footer>
        <script src="{% static 'js/vendor/jquery-2.1.4.min.js' %}"></script>
        <script src="{% static 'js/vendor/what-input.min.js' %}"></script>
        <script src="{% static 'js/foundation.min.js' %}"></script>
        {% block javascript %}{% endblock %}
        <script>$(document).foundation();</script>
    </body>
</html>

layout.html (app directory):

{% extends "layout.html" %}

{% block title %}Courses | {{ block.super }}{% endblock %}

{% block content %}
    {{ block.super }}
    <ul class="breadcrumbs">
        <li><a href="{% url 'home' %}">Home</a></li>
        <li><a href="{% url 'courses:list' %}">Courses</a></li>
        {% block breadcrumbs %}{% endblock %}
    </ul>
{% endblock %}

and quiz_form.html: (the error disappears when I delete the {{ block.super }} (the one inside block.content)

{% extends "courses/layout.html" %}

{% block title %}New Quiz | {{ course.title }} {{ block.super }} {% endblock %}

{% block breadcrumbs %}
    <li><a href="{% url 'courses:detail' pk=course.pk %}">{{ course.title }}</a></li>
{% endblock %}

{% block content %}
<div class="row columns">
{{ block.super }}
    <h1>Make a new quiz</h1>
    <form action="" method="POST">
        {% csrf_token %}
        {{ form.as_p }}
        <input type="submit" class="button" value="Save">
    </form>
</div>
{% endblock %}

I think I don't get very well the implementation of the {{ block.super }} but when I delete it from quiz_form.html, I don't have the error anymore but the tree below the nav bar disappeared (courses/Course/Text for example)

Thanks for your help
