Question

有人可以告诉我，为什么通过链接模板链接生成的URL是/.pk。我试图了解网址的工作方式。这里是Django的新手。

模板

<h1><a href="{% url 'details' pk=Testimony.id %}">{{testimony.Title}}</h1>

urls.py

urlpatterns = [
  ...
    path('<int:pk>/$', views.detail, name='details'),
]

views.py

def details(self, pk):
    print('1')
    testimony=get_object_or_404(Testimony, pk= pk)
    print('2')
    return render(request, 'details.html', {'testimony': testimony})

就像上一个问题一样，您将path()的新语法和re_path() / url()的正则表达式语法混为一谈。

path()不使用正则表达式，因此您不应在末尾加上$。更改为：

path('<int:pk>/', views.detail, name='details'),

由于模板上下文为{'testimony': testimony}，因此应在url标记中使用小写的testimony：

<h1><a href="{% url 'details' pk=testimony.id %}">{{testimony.Title}}</h1>

对代码/模板进行更改后，请确保已保存所有更改并重新启动服务器，以确保您正在运行自己认为的代码。

找不到页面：/<int:pk>.pk
