Question

我刚刚改变了我的应用程序中的一些URL，当我尝试渲染索引页面时，我收到此错误。有人能告诉我这是什么问题吗？我检查了我的html文件中的拼写错误等。错误如下：

Reverse for 'video_list' with arguments '()' and keyword arguments '{}' not  found. 1 pattern(s) tried: [u'website/video/(?P<pk>[a-z\\d]+)/$']

我在我的应用程序的url.py中有以下内容：

import views
admin.autodiscover()

video_detail = DetailView.as_view(model=Video)  
video_list = ListView.as_view(model=Video)

urlpatterns = patterns('',
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^website/(?P<pk>[a-z\d]+)/$', views.VideoListView.as_view(),  name='video_list'),
    url(r'^website/(?P<pk>[a-z\d]+)/$', video_detail, name='video_detail'),
    url(r'^website/(?P<pk>[a-z\d]+)/$', video_detail, name='video_recording'),
    url(r'^(?P<video_id>[a-z\d]+)/post_comment/$', views.post_comment, name='post_comment'),
)

我的index.html有，

{% load staticfiles %}

<link rel="stylesheet" type="text/css" href="{% static 'website/style.css' %}" />

<head>
<h1> Title </h1>

<style>

ul {
    margin: 0;
    padding: 0;
}

li {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica   Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: normal;
    font-size: 20px;
    display: inline;
    color: green;
}
</style>
</head>  
<body>

<ul>
  <li><a href={% url 'website:video_list'%}>{{ "View Videos" }}</a></li>
  <li><a href="#news">Record Video</a></li>
</ul>
</body>

堆栈跟踪是：

Answer 1

您正在模板中执行此操作：

{% url 'website:video_list'%}

...但你的网址有：

url(r'^website/(?P<pk>[a-z\d]+)/$', views.VideoListView.as_view(),  name='video_list'),

换句话说，您的网址中的pk arg是必需的，但是您要求Django在没有指定任何pk的情况下撤消网址。

您可能不希望列表视图的网址中有pk段，因此您的urlconf应如下所示：

url(r'^website/$', views.VideoListView.as_view(),  name='video_list'),
url(r'^website/(?P<pk>[a-z\d]+)/$', video_detail, name='video_detail'),

Django URL不起作用：NoReverseMatch错误
