與意外的論點沒有反向匹配

Question

我很久沒有使用Django了。我忘記了如何解決很多常見的問題。 該網站在Dj 1.3上。有一天剛開始返回一個錯誤：

Exception Value:  
Reverse for 'page' with arguments '(u'yoga-class',)' and keyword arguments '{}' not found. 

我沒有通過任何參數。傳遞的參數是沒有域名的域名，完整域名是yoga-class.in.ua。網站工作了2年。

查看：

class Index(ListView): 
"""Front page, different from the list of posts just extra header. 
On this page displayes category with checked "frontpage" checkbx.""" 

template_name = 'shivaapp/index.djhtml' 
context_object_name = 'post_list' 

def get_queryset(self): 
    news = PostPages.objects.filter(parent_category__frontpage=True) 
    news = news.order_by('move_to_top').reverse() 
    return news 

def get_context_data(self, **kwargs): 
    """Extra data for header shifters.""" 

    context = super(Index, self).get_context_data(**kwargs) 
    context['slideshow'] = ShivaImage.objects.filter(
            slide_show=True).order_by('ordering') 
    context['dictums'] = Dictum.objects.order_by('ordering') 
    return context 

網址：

urlpatterns = patterns('', 
    url(r'^$', Index.as_view(paginate_by=5)), 
    (r'^feed/$', RSSFeed()), 
    (r'^search', Search.as_view()), 
    (r'^description/$', markdown_desc), 
    (r'^redirect/(?P<url>\w+)/$', redirect_view), 
    url(r'^cat/(?P<hash>[\w+\s]*)/$', 
     CategorizedPostsView.as_view(paginate_by=5)), 
    url(r'^page/(?P<slug>\w+)/$', PageOrSinglePost.as_view(), name='page'), 
    url(r'^post/(?P<slug>\w+)/$', PageOrSinglePost.as_view(), name='post'), 
) 

的httpd.conf：

Alias /robots.txt /var/www/path/to/robots.txt 
Alias /favicon.ico /var/www/path/to/favicon.ico 

AliasMatch ^/([^/]*\.css) /var/www/i159/path/to/site_media/static/css/$1

我應該怎麼找？

Answer 1

在你的url正則表達式中，你使用的是\w+，其中參數是yoga-class。該-不屬於\w+字符類，因此錯誤。

您需要更新此：

url(r'^page/(?P<slug>\w+)/$', PageOrSinglePost.as_view(), name='page'), 

這樣：

url(r'^page/(?P<slug>[\w\-]+)/$', PageOrSinglePost.as_view(), name='page'),
