django - DetailView如何同时显示两个模型

我有两个模型：广告和横幅

当我使用“通用视图”DetailView时我怎样才能同时带两个模型下面的代码只带一个广告

我的网址.py

url(r'^(?P<pk>\d+)/$', DetailView.as_view(
    model               = Advertisment,
    context_object_name = 'advertisment',
), name='cars-advertisment-detail'),

当然可以，只需覆盖即可get_context_data向上下文添加内容。

path('<int:pk>/', YourDetailView.as_view(), name='cars-advertisment-detail'),

class YourDetailView(DetailView):
    context_object_name = 'advertisment'
    model = Advertisement

    def get_context_data(self, **kwargs):
        """
        This has been overridden to add `car` to the template context,
        now you can use {{ car }} within the template
        """
        context = super().get_context_data(**kwargs)
        context['car'] = Car.objects.get(registration='DK52 WLG')
        return context
