ChangeEmailView() 得到了一个意外的关键字参数 'token'

Question

我正在尝试创建一个 url，其中的值来自其中的视图

    path('settings/email/changeemail/<str:token>', views.ChangeEmailView , name="changeemail"),

但是如果我进入这个页面就会出现这个错误:

Internal Server Error: /settings/email/changeemail/0fdb9ef1-ce86-482e-a8ef-3fc202438ba9
Traceback (most recent call last):
 File "C:\Users\Finn\AppData\Local\Programs\Python\Python39\lib\site-packages\django\core\handlers\exception.py", line 47, in inner
   response = get_response(request)
 File "C:\Users\Finn\AppData\Local\Programs\Python\Python39\lib\site-packages\django\core\handlers\base.py", line 181, in _get_response
   response = wrapped_callback(request, *callback_args, **callback_kwargs)

   return view_func(request, *args, **kwargs)
TypeError: ChangeEmailView() got an unexpected keyword argument 'token'

这是我的views.py

@login_required(login_url='home:login')
def ChangeEmailView(request):
        if request.method == 'POST':
            objects = User.objects.get(email = request.user.email)
            form = EmailChangingForm(request.POST, instance=objects)
            packet = get_object_or_404(TempUrl, user=request.user)
            token = packet.uid
            if form.is_valid():
                form.save()
                
            return redirect('home:profilesettings')
            
        else:
            objects = User.objects.get(email = request.user.email)
            form = EmailChangingForm(request.POST, instance=objects)
            packet = get_object_or_404(TempUrl, user=request.user)
            token = packet.uid
        context = {'form': form, 'token': token}
        return render(request, 'home/email_settings.html', context)

最后我想要一个唯一的url，令牌从中保存在数据库中

这是生成 uuid 并放入数据库的另一个视图

def load_url(request):
   token = uuid.uuid4()
   objects = TempUrl.objects.update_or_create(user = request.user, uid=token, used=False)
   print("Das ist der Token:" + str(token))

   context = {'token': token}



   return render(request, 'home/changeemail_pre.html', context)

您还必须将参数添加到视图中。

def changeEmailView(request, token):
    ...

这就是它说意外关键字的原因。因为关键字在那里，但视图不期望它。

ChangeEmailView() 得到了一个意外的关键字参数 'token'
