ChangeEmailView() 有一个意外的关键字参数'token'

Question

我试图使一个url与一个值从它的视图

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

，但是如果我进入

页面，出现这个错误:

Internal Server Error: /settings/email/changeemail/0fdb9ef1-ce86-482e-a8ef-3fc202438ba9
Traceback (most recent call last):
File "C:UsersFinnAppDataLocalProgramsPythonPython39libsite-packagesdjangocorehandlersexception.py", line 47, in inner
response = get_response(request)
File "C:UsersFinnAppDataLocalProgramsPythonPython39libsite-packagesdjangocorehandlersbase.py", line 181, in _get_response
response = wrapped_callback(request, *callback_args, **callback_kwargs)
File "C:UsersFinnAppDataLocalProgramsPythonPython39libsite-packagesdjangocontribauthdecorators.py", line 21, in _wrapped_view
return view_func(request, *args, **kwargs)
TypeError: ChangeEmailView() got an unexpected keyword argument 'token'

this is my 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的令牌是保存在db

是另一个视图，其中uid被生成并放到db

中。

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):
...

这就是为什么它说意想不到的关键字。因为关键字在那里，但视图不期望它。
