Python 与#x27相反；一部分'；带关键字参数-问题

我试着让我的url类似于描述/（party_number）-（pk），其中party_number和pk对于每个对象都是不同的。但除此之外，我得到了一个错误：

找不到具有关键字参数“{pk'：10，'nums'：'A15151'}”的“onePart”的反转。尝试了1个模式：[“描述/（？：（？P[\d]+）-（？P[\d]+）/）？$”]

在我的视图中。py:

def PartyNumView(request, page_number = 1):
    all_parties = Part.objects.all()
    current_page = Paginator(all_parties, 2)
    try:
        context = current_page.page(page_number)
    except PageNotAnInteger:
        context = current_page.page(1)
    except EmptyPage:
        context = current_page.page(current_page.num_pages)
    return render_to_response('part_list.html', {'PartyNum': context})


def forOne(request, pk):
    onePart = get_object_or_404(Part, pk=pk)
    return render_to_response('singlePart.html', {'onePart': onePart})

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^parties/(?P<page_number>[\d]+)/$', PartyNumView),
    url(r'^parties', PartyNumView),
    url(r'description/(?:(?P<nums>[\d]+)-(?P<pk>[\d]+)/)?$', forOne, name='onePart'),
    url(r'^main/', TemplateView.as_view(template_name='main.html')),       #static html
    url(r'^measures/', TemplateView.as_view(template_name='IcDesc.html')),       #static html

{% for object in PartyNum %}

    <tr>
      <td>{{ forloop.counter }}</td>

您应该更改URL参数的位置，将

参与方编号

作为模板中的第一个参数

<td><a href="{% url 'onePart' nums=object.Party_number pk=object.pk %}">...</td>
