Django - 模板上下文处理器 - 打破我的应用程序

Question

我试图建立一个像本文提到的模板上下文处理器,以便我可以为每个模板提供信息.

我在views.py中写了这个函数:

def items_in_cart(request):
    """Used by settings.TEMPLATE_CONTEXT_PROCESSORS to provide an item count
    to every template"""
    cart, lines = get_users_cart_and_lines(request)
    return {'items_in_cart': lines.count()}

然后我将此行添加到settings.py:

TEMPLATE_CONTEXT_PROCESSORS = ('Store.views.items_in_cart',)

但现在每当我去任何页面时都会收到此错误:

ImproperlyConfigured at /

Put 'django.contrib.auth.context_processors.auth' in your TEMPLATE_CONTEXT_PROCESSORS setting in order to use the admin application.

我做错什么了吗？这里发生了什么？我尝试做错误所说的内容,然后它将呈现一个页面,其中包含我的所有样式表和图像.

Django有一组默认的TEMPLATE_CONTEXT_PROCESSORS,您需要在添加自己的时手动添加.http://docs.djangoproject.com/en/1.3/ref/settings/#template-context-processors

根据您的Django版本,这些是不同的,但是如果使用Django 1.3,您可能会有以下内容

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.core.context_processors.static",
    "django.contrib.messages.context_processors.messages",
    "Store.views.items_in_cart",
)
