only the word "Course" appears on /courses/1/ page. Where are the details?

Python Django course, video: 40782

learning_site/courses/urls.py:

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^$', views.course_list),
    url(r'(?P<course_pk>\d+)/(?P<step_pk>\d+)/$', views.step_detail),
    url(r'(?P<pk>\d+)/$', views.course_detail),
]

learning_site/templates/layout.html:

{% load static from staticfiles %}

<!doctype html>
<html>
    <head>
        <title>{% block title %}{% endblock %}</title>
        <!-- use a static tag instead of STATICURL if loation can change like on S3 -->
        <link rel="stylesheet" href="{% static 'css/layout.css' %}">
    </head>
    <body>
        <div class="site-container">
            {% block content %}{% endblock %}
        </div>
    </body>
</html>

learning_site/courses/views.py:

from django.http import HttpResponse
from django.shortcuts import render, get_object_or_404

from .models import Course, Step

def course_list(request):
    courses = Course.objects.all()
    return render(request, 'courses/course_list.html', {'courses': courses})

def course_detail(request, pk):
    course = Course.objects.get(pk=pk)
    course = get_object_or_404(Course, pk=pk)
    return render(request, 'courses/course_detail.html', {'course':'course'})

def step_detail(request, course_pk, step_pk):
    step = get_object_or_404(Step, course_id=course_pk, pk=step_pk)
    return render(request, 'courses/step_detail.html', {'step':'step'})

learning_site/courses/templates/courses/course_details.html

{% extends "layout.html" %}

{% block title %} {{ course.title}} {% endblock%}

{% block content %}
<article>
    <h2>{{ course.title }}</h2>
    {{ course.description }}

    <section>
        {% for step in course.step_set.all %}
            <h3>{{ step.title }}</h3>
            {{ step.description}}
        {% endfor %}
    </section>
</article>
{% endblock %}

thanks!

In your view, you are passing a literal string 'course' in the context dict instead of the variable course. Remove the quotes:

    return render(request, 'courses/course_detail.html', {'course':course})

Are you sure there are more details to show? What happens if you do the following:

python manage.py shell
>>> from .models import Course

>>> course_one = Course.objects.get(pk=1)

>>> print(course_one.title, course_one.description, course_one.step_set.count())

hello chris, thanks for the reply. using the shell as you suggested shows the correct steps listed. If you check 5:34 in the video, you'll see the step listed on the page. However mine doesn't show that.

Looks like i'm not the only one and it hasn't been answered yet:
