我使用的是Python 2.7.5，django 1.6.2和bootstrap 3。
我知道自django 1.5以来模板标记{% url %}已更改。我已经阅读了django网站上的documentation for reverse url，但我必须做错事，因为我无法让它发挥作用。
这是我的团队/ urls.py，我使用名为url delete_team_url：
from django.conf.urls import patterns, url
import teams.views
urlpatterns = patterns('',
url(r'^$', teams.views.index, name='teams_index'),
url(r'^new-team/$', teams.views.index, {'add_new_team':True}, name='teams_index_new_team'),
url(r'^delete/$', teams.views.delete_team, name='delete_team_url'),
)
这是项目全球urls.py:
from django.conf.urls import patterns, include, url
from django.contrib import admin
import bbch.views
import auth.views
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^rosetta/', include('rosetta.urls')),
url(r'^i18n/', include('django.conf.urls.i18n')),
url(r'^auth/', include('auth.urls', namespace="auth")),
url(r'^rules/', include('rules.urls', namespace="rules")),
url(r'^forum/', include('forum.urls', namespace="forum")),
url(r'^teams/', include('teams.urls', namespace="teams")),
url(r'^accounts/login/$', auth.views.connection, {'log_required':True}),
url(r'^home/log_in/$', bbch.views.home, {'log_message':True}, name="home_log_message"),
url(r'^home/$', bbch.views.home, name="bbch"),
url(r'^$', bbch.views.home, name="bbch"),
)
以下是我的观点（我仅使用虚拟id=0进行测试）：
def delete_team(request):
team = teams.models.Team.objects.get(id=0)
team.delete()
return render(request, 'teams/index.html', context)
最后这是我的html代码部分，我使用反向网址模板标记：
<div class="row">
<div class="col-md-2">
<a href="{% url 'delete_team_url' %}" class="btn btn-danger delete-team"><span class="glyphicon glyphicon-trash"></span> {% trans "Delete team" %}</a>
</div>
<div class="col-md-2">
<a href="#" class="btn btn-info edit-team"><span class="glyphicon glyphicon-pencil"></span> {% trans "Edit team" %}</a>
</div>
<div class="col-md-2 col-md-offset-6 btn-right">
<a href="#" class="btn btn-success add-player"><span class="glyphicon glyphicon-plus"></span> {% trans "Add a player" %}</a>
</div>
</div>
我收到以下错误：
NoReverseMatch at /teams/
Reverse for 'delete_team_url' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

编辑：这是teams.views.index（由黄鼠狼询问）：

也许是因为您的网址模式末尾缺少$（美元）符号，您会收到此错误。
你应该试试这个：
url(r'^new-team/$' ...),
url (r'^delete/$' ...),
<强>更新
好的，明白了。您在自己的网址中使用了命名空间，这就是您使用{% url %}标记的原因，如下所示：
<a href="{% url 'teams:delete_team_url' %}" ... > ... </a>

我只是浏览了你的代码，但看起来像{％url＆＃39; teams：delete_team_url＆＃39; ％}就是你想要的。
（＆＃34;名称空间＆＃34;在您的顶级urls.py中成为属于它的视图名称的名称空间;这些名称由＆＃34;：＆＃34;从视图名称中分隔）
