如何在django 1.6中使用django模板标签'url'？ [英] How to use django template tag 'url' with django 1.6?
问题描述
我正在使用Python 2.7.5，django 1.6.2和bootstrap 3。
I'm using Python 2.7.5, django 1.6.2 and bootstrap 3.
我知道模板标签 {％url％ } 从Django 1.5开始更改。我已阅读有关反向URL的文档在django网站上，但是我必须做一些错误的事情，因为我无法使它正常工作。
I know the template tag {% url %} changed since django 1.5. I've read the documentation for reverse url on django website but I must do something wrong because I can't get it to work.
这是我的team / urls.py，我使用的是url delete_team_url ：
Here is my teams/urls.py, I use the named 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/$', teams.views.delete_team, name='delete_team_url'),
)
这是项目全局urls.py：
Here is the project global urls.py :
from django.conf.urls import patterns, include, url
from django.contrib import admin
import bbch.views
import auth.views
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^rosetta/', include('rosetta.urls')),
url(r'^i18n/', include('django.conf.urls.i18n')),
url(r'^auth/', include('auth.urls', namespace="auth")),
url(r'^rules/', include('rules.urls', namespace="rules")),
url(r'^forum/', include('forum.urls', namespace="forum")),
url(r'^teams/', include('teams.urls', namespace="teams")),
url(r'^accounts/login/$', 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"),
)
这是我的观点（我只是为了测试而使用虚拟 id = 0 ）：
Here is my view (I'm using dummy id=0 just for the test) :
def delete_team(request):
team = teams.models.Team.objects.get(id=0)
team.delete()
return render(request, 'teams/index.html', context)
最后是我的html代码部分，在其中使用反向URL模板标记：
And finally here is my html code part where I use the reverse url template tag :
<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 （由鼬鼠提出）：
Edit : Here is the teams.views.index (asked by weasel) :

推荐答案
也许是因为您的末尾缺少 $ （美元）符号urlpatterns，您会收到此错误。
Perhaps because of the missing $ (dollar) sign at the end of your urlpatterns you're getting this error.
您也许应该尝试以下操作：
You should perhaps try this:
url(r'^new-team/$' ...),
url (r'^delete/$' ...),
更新：
好的，知道了。您在网址中使用名称空间，这就是为什么必须使用 {％url％} 标记的原因，如下所示：
Okay, got it. You're using namespace in your urls which is why you've to use {% url %} tag something like below:
<a href="{% url 'teams:delete_team_url' %}" ... > ... </a>
