Python 未找到页面：/<；int:pk>；。主键

有人能告诉我为什么通过点击模板链接生成的URL是/.pk吗。我试图理解URL是如何工作的。这里是Django的新手

与上一个问题一样，您混淆了

path（）

的新语法和

re\u path（）

/

url（）

的正则表达式语法

path（）

不接受正则表达式，因此不应在末尾包含

$

。将其更改为：

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

---

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，以确保正在运行您认为正确的代码。

删除

$

。

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

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

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

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