Traceback:

Exception Type: error at /blog/archives

，并在这里不用我URLS.PY

from django.conf.urls import patterns, include, url 

from django.views.generic import ListView, DetailView 

from blog.models import Post 

urlpatterns = patterns('', 

    url(r'^$', 
     ListView.as_view(
       queryset=Post.objects.order_by("-created")[:2], 
       template_name="blog.html")), 

     url(r'^(?p<pk>\d+)/$', 
     DetailView.as_view(
       model=Post, 
       template_name="post.html")), 
    url(r'^archives/$', 
     ListView.as_view(
       queryset=Post.objects.all().order_by("-created"), 
       template_name="archives.html")), 
    url(r'^tags/(?p<tag?\w+)/$', 'tagpage'),       

)

也许那里是一个错误：url(r'^tags/(?p<tag?\w+)/$', 'tagpage')？我认为应该是：url(r'^tags/(?p<tag>\w+)/$', 'tagpage')。

$url(r'^tags/(?p<tag?\w+)/$', 'tagpage'),

替换字符？与>

感谢您的回复..亚我取代了它，但还是错误是一样的（“模式意外结束），并更换 – user1667677

哪一个？ –

更换URL（R'^标签/（P <标签（r'^ tags /（？p \ w +）/ $'，'tagpage'）， – user1667677

除了代替>的?，所述p需要是大写。

r'^tags/(?P<tag>\w+)/$'
