Я получаю это исключение в своем браузере, я видел до 20 сообщений, связанных с этой ошибкой, но я не мог найти решение. Я новичок в Django, пожалуйста, помогите мне, спасибо заранее.

мой имя_проекта/urls.py

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

Мой 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> -->

    {% endfor %} 
{% endblock %} -->

Answer 1

Вы имеете в виду вид имени blog_detail в blog_list.html, но нет вида с этим именем. В вашем appname/urls.py у вас есть только blog_list.
