NoReverseMatch (Fehler beim Rendern der Vorlage)

Question

Ich erhalte diese Ausnahme in meinem Browser, ich habe bis zu 20 Beiträge zu diesem Fehler gesehen, aber ich konnte keine Lösung finden. Ich bin neu in Django, bitte hilf mir, Danke im Voraus.

mein Projektname/urls.py

urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url(r'', include('blog.urls')), 
] 

Mein views.py

def blog_list(request): 
    return render(request, 'blog/blog_list.html', {}) 

blog_list.html

<!-- {% extends 'blog/base.html' %} 

{% block content %} 
    {% for post in posts %} 
     <div class="post"> 
      <div class="date"> 
       {{ post.name }} 
      </div> --> 
      <!-- <h1><a href="{% url 'blog_detail' pk=post.pk %}">{{ post.name }}</a></h1> --> 

<!--   </div> 
    {% endfor %} 
{% endblock %} -->

Sie auf eine Ansicht beziehen blog_detail in blog_list.html genannt, aber es gibt keine Aussicht mit diesem Namen. In deinem Appname/urls.py hast du nur blog_list.
