Python Django模板上下文错误

当我尝试运行我的模板上下文处理器时，我得到了“超过最大递归深度”

settings.py如下所示：

TEMPLATE_CONTEXT_PROCESSORS = (
    'django.contrib.auth.context_processors.auth',
    'django.core.context_processors.i18n',
    'django.core.context_processors.request',
    'django.core.context_processors.media',
    'django.core.context_processors.static',
    'cms.context_processors.media',
    'sekizai.context_processors.sekizai',
    'web.context_content.base_context',
)

web/context_content.py：

from web import models
from django.shortcuts import render
from django.shortcuts import render_to_response
from django.template import RequestContext
#from django.conf import settings

def base_context(request):

    categories = models.Category.objects.filter()

    return render(request, "base.html", {'categories':categories})

不知道为什么我会犯这样奇怪的错误

更新：my urls.py（站点）：

---

我不确定你想用上下文处理器做什么。它们用于向模板上下文添加项，并且应该始终返回字典：但是由于某些原因，您在函数中呈现模板。由于上下文处理器由渲染快捷方式调用，因此函数最终会调用自身，从而产生无限递归

---

不要在您的上下文处理器中呈现模板。

您可以显示站点的

url.py

和应用程序的

url.py

。我的意思是

url.py

文件，您在其中定义了站点的所有URL。我已经添加了两个url.py文件

from django.conf.urls.defaults import *
from django.conf.urls.i18n import i18n_patterns
from django.contrib import admin
from django.conf import settings
from django.contrib.auth.views import login, logout
from web import views
from web import forms

admin.autodiscover()

urlpatterns = i18n_patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^register/$', views.register),
    url(r'^login/$', views.login),
    #url(r'^index/$', include('web.urls'))
    url(r'^', include('cms.urls'))
)

if settings.DEBUG:
    urlpatterns = patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve',
        {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
    url(r'', include('django.contrib.staticfiles.urls')),
) + urlpatterns

from django.conf.urls.defaults import *
from django.contrib import admin
from django.conf import settings
from django.conf.urls import patterns, include, url
from web import views
from web import forms

admin.autodiscover()

urlpatterns = patterns('web.views',
    #url(r'^', views.base_context),
)
