Question

我收到了错误，

NoReverseMatch at /app/detail/3/
Reverse for 'detail' with arguments '('',)' not found. 1 pattern(s) tried: ['app/detail\\/(?P<pk>[0-9]+)\\/$'] .

我在views.py中写道

def top(request):
    content = POST.objects.order_by('-created_at')[:5]
    page = _get_page(blog_content, request.GET.get('page'))
    return render(request, 'top.html',{'content':content,"page":page})

class DetailView(generic.DetailView):
    model = POST
    template_name = 'detail.html'

top.html中的

<div>
         {% for content in page %}
            <h2>{{ content.title }}</h2>
            <p><a href="{% url 'detail' content.pk %}">SHOW DETAIL</a></p>
         {% endfor %}
</div>

in detail.html

<div>

        <h2>Comment List</h2>

        <a href="{% url 'comment' pk %}">Comment</a>

        {% for comment in post.comment_set.all %} Name:{{ comment.name }}
        <br> Text:{{ comment.text }}
        <br>

        <a href="{% url 'recomment' comment.pk %}">Reply</a>
        <br> {% endfor %}

    </div>


    <div>

        <h2>Comment Form</h2>

        <form action="" method="POST">

            {{ form.as_p }} {% csrf_token %}

            <button type="submit">Send</button>

        </form>

    </div>

在urls.py中

urlpatterns = [
    path('top/', views.top, name='top'),
    path('detail/<int:pk>/', views.DetailView.as_view(template_name='detail.html'), name='detail'),
    path('comment/<int:pk>/',views.comment, name='comment'),
    path('recomment/<int:pk>/', views.recomment, name='recomment'),
]

当我访问top.html时，网站显示正确，所以没关系。但是当我放置SHOW DETAIL链接时，会发生此错误。我真的不明白为什么会发生这种错误。

NoReverseMatch at / app / detail / 3 /
