Django标记:通过指定多个标记来抓取对象?

我目前在 urls.py 它为我的虫子带来了孤独的永久链接:

from django.conf.urls.defaults import *

from tagging.views import tagged_object_list

from bugs.models import Bug

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Example:
    # (r'^workarounds/', include('workarounds.foo.urls')),

    # Uncomment the admin/doc line below and add 'django.contrib.admindocs' 
    # to INSTALLED_APPS to enable admin documentation:
    # (r'^admin/doc/', include('django.contrib.admindocs.urls')),

    (r'^$', 'django.views.generic.simple.direct_to_template', {'template':'homepage.html'}),

    (r'^bugs/(?P<slug>[-\w]+)/$', 'bugs.views.bug_detail'),
    (r'^bugs/tagged/(?P<tag>[^/]+)/$', 
    'tagging.views.tagged_object_list',
    {
        'queryset_or_model': Bug,
        'template_name' : 'tag/lone.html'}),
    # Uncomment the next line to enable the admin:
    (r'^admin/', include(admin.site.urls)),
)

如果我指定了一个url, bugs/tagged/firefox firefox+css 将返回所有标记为 firefox 和 css .
