Question

我在浏览器中遇到此异常，我已经看到多达 20 篇与此错误相关的帖子，但我找不到任何解决方案。我是 Django 的新手，请帮助我，在此先感谢。

我的项目名/urls.py

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

我的观点.py

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

博客列表.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 %} -->

Answer 1

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