使用 Django 标记时 URL 中的未知说明符
您好，我收到以下错误；
error at /
unknown specifier: ?P[
这就是我的 URLS 文件的样子；
urlpatterns = patterns('mainpage.views',
(r'^$', 'index'),
(r'^post/(?P<id>\d+)/$', 'post'),
(r'^projects/$', 'projects'),
(r'^about/$', 'about'),
(r'^tags/$', 'tags'),
(r'^tag/(?P[-_A-Za-z0-9]+)/$', 'with_tag'),
(r'^tag/(?P[-_A-Za-z0-9]+)/page/(?Pd+)/$', 'with_tag'),
(r'^comments/$', include('django.contrib.comments.urls'))
视图名称为 with_tag 的两个 URL 是违规 URL。我正在关注本教程；
让标记在我的网站上正常工作。我正在使用 Django 标记 1.3.1 和 Python 2.7。
谁能告诉我我对 URLS.py 文件做错了什么？我正在按书本复制教程，但与教程中使用的设置相比，我的设置一定有不同吗？

The two URLS with a view name of with_tag are the offending urls. I am following this tutorial;

Can anyone tell me what I am doing wrong to my URLS.py file please? I am copying the tutorial by the book but there must be something different in my set up compared to the set up used in the tutorial?

这与 django 标记无关，这是一个正则表达式语法错误。
?P表示命名组，并且需要在其后添加名称：?P。因此，要么向您的组添加名称，要么对它们进行编号（即删除?P部分）。This is not related to django-tagging, it's a regex syntax error.
?Pindicates a named group, and requires a name after it:?P<foo>. So, either add names to your groups, or make them numbered (i.e. remove?Ppart).
