django-1.4 - Django 1.4 到 Django 1.5 直接到模板 extra_context

Question

因此 Django 1.5 不再使用 direct_to_template 调用。

我正在移植一些 url，但我被这个阻止了。

url(r'^system_settings/$',
    'django.views.generic.simple.direct_to_template',
    {
        'template': 'helpdesk/system_settings.html',
        'extra_context': {
            'ADMIN_URL': getattr(settings, 'ADMIN_URL', '/admin/'),
        },
    },

我知道我可以用

url(r'^help/context/$',
    TemplateView.as_view(template_name='helpdesk/system_settings.html')...

但我不知道 extra_context 应该去哪里。有什么见解吗？

引用:https://docs.djangoproject.com/en/dev/topics/class-based-views/generic-display/#adding-extra-context

from django.views.generic import TemplateView
from django.utils.decorators import classonlymethod

utils.autodiscover()
class ExtraContextTemplateView(TemplateView):

    @classonlymethod
    def get_context_data(self, **kwargs):
        context = super(ExtraContextTemplateView, self).get_context_data(**kwargs)
        context['ADMIN_URL'] = getattr(settings, 'ADMIN_URL', '/admin/')
        return context

urlpatterns = patterns('',
    url(r'^help/context/$', ExtraContextTemplateView.as_view(template_name='helpdesk/system_settings.html')
)
