扩展Django Flatpages - 注销

Question

我正在创建一个运行virtualenv的简单Django应用程序（1.3.1）。它在WebFaction上启动并运行。这很简单，只能保证使用Flatpages - 我还想对FlatPages做一些改进，所以我只是扩展模型 - 没有什么复杂的。

models.py

from django.db import models
from django.contrib.flatpages.models import FlatPage

class ExtendedFlatPage(FlatPage):
    order = models.PositiveIntegerField(unique=True)

    class Meta:
        ordering = ["order"]
        verbose_name = "Page"

问题与退出有关。当我尝试从入口点退出到站点时没有问题，例如http：// {domainname} / admin / logout /但是，当我尝试从管理站点中进一步注销系统时 - 示例在扩展的FlatPages列表中http：// {domainname} / admin / basic / extendedflatpage /然后注销（http：// {domainname} / admin / basic / extendedflatpage / logout /）生成错误，煮沸到最后的观察

ValueError: invalid literal for int() with base 10: 'logout'

urls.py

from django.conf.urls.defaults import patterns, include, url
from django.views.generic.simple import redirect_to
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    (r'^favicon\.ico$', 'django.views.generic.simple.redirect_to', {'url': '/static/images/favicon.ico'}),
)

在互联网上狩猎带回了following page并建议修复。问题是，我似乎无法实现这一点 - 我试图实现这一点的方法是调整urls.py如下：

...
admin.autodiscover()
admin.site.root_path = '/admin/' #should this go here?
urlpatterns = patterns('',
...

更新05/07/2012

我已经在post here中进行了一些观察并应用于应用以进行修复，并在我的扩展平面应用中创建了一个新视图

views.py

def logout(request):
    from django.contrib.auth.views import logout
    return logout(request)

然后我将此视图导入urls.py并调用此

urls.py

...
from basic.views import logout as custom_logout
...
urlpatterns = patterns('',
    url(r'/logout/$', custom_logout),
    url(r'^admin/', include(admin.site.urls)),
...

虽然这现在解决了我的问题，但似乎我在某种程度上修补了一些东西。

有人可以建议一个更简洁的方法吗？或者我在这里应用的补丁是否合理？
