Django 中 get_object_or_404 的问题

Question

我有一个错误，我似乎无法让我的代码的这部分工作。它给了我以下错误“element_id”是此函数的无效关键字参数。

起初，我看到我没有调用正确的模型，我已经改变了它，但它似乎仍然不起作用。

def Input(request, element_id, session_id):

    input_element = get_object_or_404(InputData, pk=element_id)

    voice_service = input_element.service

    session = lookup_or_create_session(voice_service, session_id)

    if request.method == "POST":

        session = get_object_or_404(CallSession, pk=session_id)

        value = 'DTMF input'

        result = UserInput()

        result.session = session

        result.category = input_element.input_category 

        result.save()

        return redirect(request.POST['redirect'])

    session.input_step(input_element)

    context = input_generate_context(input_element, session)

    context['url'] = request.get_full_path(False)

    return render(request, 'input.xml', context, content_type='text/xml')

输入数据模型：

class InputData(VoiceServiceElement): 

    """

        An element that saves user input to a line in the database.

    """

    _urls_name = 'service-development:InputData'

    ask_input_label = models.BooleanField(_('Ask the user to fill something in'), default=True)

    input_voice_label = models.ForeignKey(

        VoiceLabel,

        verbose_name = _('Ask input label'),

        help_text = _('The voice label that is played before the system asks the user to fill in the input'),

        on_delete=models.SET_NULL,

        null=True,

        blank=True,

        related_name='ask_input_label_input'

    )

    ask_confirmation = models.BooleanField(

        _('Ask the caller to confirm their input'), default=True)

    ask_confirmation_voice_label = models.ForeignKey(

        VoiceLabel,

        verbose_name = _('Ask for confirmation voice label'),

        help_text = _('The voice label that asks the user to confirm their pinput. Example: "Are you satisfied with your recording? Press 1 to confirm, or press 2 to retry."'),

        on_delete=models.SET_NULL,

        null=True,

        blank=True,

        related_name='confirmation_voice_label_input',

    )

有人可以帮我吗？

您需要更新urls.py或更改您的views.py文件，以便 url 与函数名称匹配。视图.pydef Input(request, element_id, session_id):&nbsp; &nbsp;...网址.pyapp_name= 'service-development'urlpatterns = [&nbsp; &nbsp; ...&nbsp; &nbsp; url(r'^InputData/(?P<element_id>[0-9]+)/(?P<session_id>[0-9]+)$', views.Input, name='Input')]
