Question

需要帮助。我似乎无法解决这个问题。这里是 Django 的新手。

Traceback (most recent call last):
  File "C:\Users\hanya\AppData\Local\Programs\Python\Python37\lib\site-packages\django\core\handlers\exception.py", line 34, in inner
    response = get_response(request)
  File "C:\Users\hanya\AppData\Local\Programs\Python\Python37\lib\site-packages\django\core\handlers\base.py", line 126, in _get_response
    response = self.process_exception_by_middleware(e, request)
  File "C:\Users\hanya\AppData\Local\Programs\Python\Python37\lib\site-packages\django\core\handlers\base.py", line 124, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)
TypeError: __init__() takes 1 positional argument but 2 were given

模板

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

urls.py

urlpatterns = [
    ...
    re_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})

Answer 1

<int:pk> 应与 path 一起使用，而不是 re_path。

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