在我的维护应用程序中，我有六个模型。我将只包括与这个问题相关的模型中的 2 个。有一个正确显示的设备列表( ListView )。但是，我在为每个设备创建 DetailView 时遇到问题。当我去 http://127.0.0.1:8000/maintenance/equipments/1它应该显示与设备 1 相关的所有设备实例(详细信息)，但它会返回设备列表页面，即 http://127.0.0.1:8000/maintenance/equipments/ .

我已经在这里解决了很多与此类似的问题并应用了它们，但我仍然无法让 DetailView 工作。我真的很感激任何帮助。谢谢。进行更改后，我遇到了这个回溯错误

请您参考如下方法:
您的url不正确
代替
url(r'^equipment(?:/(?P<pk>\d+))?/$', views.EquipmentDetailView.as_view(), name="equipment_detail"),
应该是:
url(r'^equipment/(?P<pk>\d+)/$', views.EquipmentDetailView.as_view(), name="equipment_detail"),
