{% url %} 在 Django 1.4 中不起作用

Question

当我在任何模板中使用{% url home %} 或任何其他参数时，我都会收到此错误'str' object has no attribute 'regex'。

似乎传递给url的任何参数都是作为字符串传递的，我不确定url是否采用这种方式。

这里有什么我遗漏的吗，我应该向 TEMPLATE_CONTEXT_PROCESSORS 或 MIDDLEWARE_CLASSES 或任何其他值添加任何新值。

我的 MIDDLEWARE_CLASSES 是

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'pagination.middleware.PaginationMiddleware',
)

和 TEMPLATE_CONTEXT_PROCESSORS 是

TEMPLATE_CONTEXT_PROCESSORS = ('django.contrib.auth.context_processors.auth',
          'django.core.context_processors.request',
          'django.core.context_processors.csrf',
          'django.core.context_processors.static',
          "django.core.context_processors.media",
          'django.core.context_processors.debug',
          'django.core.context_processors.i18n',)

我的 myproject/urls.py 是

urlpatterns = patterns('',
    #Action urls go here
     url(r'^home/$', 'website.home.views.home', name='home'),

    #Contentdeveloper urls go here
     (r'^contentdeveloper/', include('website.contentdeveloper.urls')),

    #Static urls go here
     (r'^static/(?P<path>.*)$', 'django.views.static.serve',
      {'document_root': settings.STATIC_ROOT, 'show_indexes': True}),
)

我的 Views.py 是

def home(request):
   return render_to_response('home/home.html', {}, context_instance=RequestContext(request))

我在 home/home.html 中的模板代码是

{% extends "base.html" %}
{% block content %}
    {% url home %}
{% endblock %}

然后是整个Traceback

  476.     return iri_to_uri(resolver._reverse_with_prefix(view, prefix, *args, **kwargs))

  363.         possibilities = self.reverse_dict.getlist(lookup_view)
File "C:\Python27\lib\site-packages\django\core\urlresolvers.py" in reverse_dict
  276.             self._populate()
File "C:\Python27\lib\site-packages\django\core\urlresolvers.py" in _populate
  253.                     for name in pattern.reverse_dict:
File "C:\Python27\lib\site-packages\django\core\urlresolvers.py" in reverse_dict
  276.             self._populate()
File "C:\Python27\lib\site-packages\django\core\urlresolvers.py" in _populate
  243.             p_pattern = pattern.regex.pattern

更新：

在调试时发生了连线的事情，我在 _populate 函数中的 django\core\urlresolvers.py 处放置了一个 try except 块，在那里发生了异常并且一切都神奇地开始工作了。

我在这里很困惑，这是一个 django 错误还是我可能做了什么导致了问题。

我希望你已经使用了：{% load url from future %}，然后使用{% url 'home' %}。可以参考here。
