python - 在通用 View 上收到意外的关键字参数 'pk'

Question

我正在尝试使用内置的 UpdateView 和 DeleteView，并且我不断收到 TypeErrors，异常值:

get() got an unexpected keyword argument 'pk'

views.py

class SeqRunUpdate(LoginRequiredMixin, UpdateView):
    form_class = Sequencing_RunsForm
    model = Sequencing_Runs

class SeqRunDelete(LoginRequiredMixin, DeleteView):
    model = Sequencing_RunsForm
    success_url = reverse_lazy('seq_run-private')

urls.py

url(r'^private/Samples/(?P<pk>[0-9]+)/$', views.SampleUpdate.as_view(), name='sample-update'),
url(r'^private/Samples/(?P<pk>[0-9]+)/del$', views.SampleUpdate.as_view(), name='sample-delete'),

models.py

class Sequencing_Runs(models.Model):
    seq = models.CharField (max_length=250, unique=True, verbose_name='Sequence')
    date= models.DateField (auto_now=False, verbose_name='Date')
    classifaction = models.IntegerField(choices=CLASSIFACTION_CHOICES, default=1)

    def get_absolute_url(self):
        return reverse('table:seq_run-add')

    def __str__(self):
        return self.seq

模板

<td><form action="{% url 'table:seq_run-update' seq.pk %}" method="get" style="display: inline;">
                        {% csrf_token %}
                        <button type="submit" class="btn btn-default">
                            <span class="glyphicon glyphicon-edit"></span>
                        </button>
                    </form></td>
                    <td><form action="{% url 'table:seq_run-delete' seq.pk %}" method="get" style="display: inline;">
                        {% csrf_token %}
                        <button type="submit" class="btn btn-default">
                            <span class="glyphicon glyphicon-trash"></span>
                        </button>
                    </form></td>

您在 urls.py 中使用 SampleUpdate，但我在 views.py 中的任何位置都看不到该类，而是您有SeqRunUpdate和SeqRunDelete。在您的网址中使用相应的 View 类，错误就会消失。
