Error during template rendering

I'm getting an error when I run the application.: Reverse for 'courses/edit_quiz' with arguments '()' and keyword arguments '{'quiz_pk': 1, 'course_pk': 1}' not found. 0 pattern(s) tried: []

I'm not sure where I'm making a mistake.

my views.py

@login_required
def quiz_edit(request, course_pk, quiz_pk):
    quiz = get_object_or_404(models.Quiz, course_id=course_pk, pk=quiz_pk)
    form = forms.QuizForm(instance=quiz)
    return render(request, 'courses/quiz_detail.html', {'form': form, 'course': quiz.course})

my urls.py

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^$', views.course_list, name='list'),
    url(r'(?P<course_pk>\d+)/t(?P<step_pk>\d+)/$', views.text_detail,
        name='text'),
    url(r'(?P<course_pk>\d+)/q(?P<step_pk>\d+)/$', views.quiz_detail,
        name='quiz'),
    url(r'(?P<course_pk>\d+)/create_quiz/$', views.quiz_create,
        name='create_quiz'),
    url(r'(?P<course_pk>\d+)/edit_quiz/(?P<quiz_pk>\d+)/$', views.quiz_edit,
        name='edit_quiz'),
    url(r'(?P<pk>\d+)/$', views.course_detail, name='detail'),
]

my quiz_detail.html

{% extends 'courses/layout.html' %}
{% load course_extras %}

{% block title %}{{ step.title }} | {{ step.course.title }} {{ block.super }}{% endblock %}

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

{% block content %}
    <div class="row columns">
        <article>
            {{ block.super }}
            <h1>{{ step.title}}</h1>
            Quiz questions here
        </article>
        {% if user.is_authenticated %}
            <hr>
            <a href="{% url 'courses/edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}" class="button">Edit</a>
        {% endif %}
    </div>
{% endblock %}

If someone could lead me to the what I'm missing, I would appreciate it.

In your code, the anchor tag is causing the error:

 <a href="{% url 'courses/edit_quiz' course_pk=step.course.pk quiz_pk=step.pk %}" class="button">Edit</a>

in the href, its says 'courses/edit_quiz' when it is meant to be 'courses:edit_quiz'. You used a forward slash instead of a colon.
