我的projectname / urls.py

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

我的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> -->

Answer 1

您指的是blog_list.html中名为blog_detail的视图，但没有该名称的视图。在您的appname / urls.py中，您只有blog_list。

NoReverseMatch（模板渲染期间出错）
