Question

所以Django 1.5不再使用direct_to_template调用。

我移植了一些网址，我被此拦住了。

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/'),
        },
    },

我知道我可以使用

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？

Answer 1

参考：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')
)

Answer 2

修改上述示例以支持传递值字典

class ExtraContextTemplateView(TemplateView):

    extra_context = {}
    def get_context_data(self, **kwargs):
        context = super(ExtraContextTemplateView, self).get_context_data(**kwargs)
        context.update(extra_context)
        return context

urlpatterns = patterns('',
    url(r'^help/context/$',
        ExtraContextTemplateView.as_view(template_name='helpdesk/system_settings.html', 
                                         extra_context={'title': 'Help-System Settings'})

Answer 3

修改Shah Shah的回答，（我没有必要的50个声誉来简单评论他的帖子）：

我认为您需要更改行

context.update(extra_context)

到

context.update(self.extra_context)

因为extra_context是一个类属性。

Django 1.4到Django 1.5直接模板extra_context
