如何在django 1.6中使用模板标签'url'?
我正在使用 Python 2.7.5、Django 1.6.2 和 Bootstrap 3。
我知道从 Django 1.5 开始，模板标签 {% url %} 有所变化。我看过 Django 网站上关于反向 URL 的 文档，但我觉得我可能做错了什么，因为我无法让它正常工作。
这是我的 teams/urls.py 文件，我使用了命名 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/$', teams.views.delete_team, name='delete_team_url'),
)
这是项目的全局 urls.py 文件：
from django.conf.urls import patterns, include, url
from django.contrib import admin
import bbch.views
import auth.views
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^rosetta/', include('rosetta.urls')),
url(r'^i18n/', include('django.conf.urls.i18n')),
url(r'^auth/', include('auth.urls', namespace="auth")),
url(r'^rules/', include('rules.urls', namespace="rules")),
url(r'^forum/', include('forum.urls', namespace="forum")),
url(r'^teams/', include('teams.urls', namespace="teams")),
url(r'^accounts/login/$', 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"),
)
这是我的视图（我使用了虚拟的 id=0 只是为了测试）：
def delete_team(request):
team = teams.models.Team.objects.get(id=0)
team.delete()
return render(request, 'teams/index.html', context)
最后，这是我在 HTML 代码中使用反向 URL 模板标签的部分：
<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>
我遇到了以下错误：
NoReverseMatch at /teams/
Reverse for 'delete_team_url' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
如果你需要更多信息，请告诉我！谢谢你的帮助！
编辑：这是 teams.views.index（是 weasel 要求的）：
@login_required

我只是大致看了一下你的代码，但看起来你需要的是 {% url 'teams:delete_team_url' %}。
（在你最上面的 urls.py 文件中定义的“命名空间”，会成为下面所有视图名称的命名空间；这些视图名称和命名空间之间用“:”来分隔。）

可能是因为你的 urlpatterns 结尾缺少了 $（美元符号），所以你遇到了这个错误。
你可以试试这样做：
url(r'^new-team/$' ...),
url (r'^delete/$' ...),
更新：
明白了。你在你的网址中使用了命名空间，这就是为什么你需要像下面这样使用 {% url %} 标签：
<a href="{% url 'teams:delete_team_url' %}" ... > ... </a>
