Django DetailView通过不使用主键的两个参数进行筛选

我需要用两个值过滤模型，它们都不是模型的主键

我想过滤一辆车和一周的付款，这意味着我可以在一周内为一辆车支付多笔付款

我使用Django-Tables2来显示结果

views.py

models.py

url.py

path（'paymentsbycarandweek/'，
views.PagosDetailView.as_view（），name='pagos_bycar'）

这是我最后一次尝试几个选项，我收到以下错误消息：

通用详细信息视图PagosDetailView必须在URLconf中使用对象pk或slug调用

---

如何准确地传递这两个参数？

经过大量搜索，我最终解决了这个问题：

class PagosDetailView(SingleTableMixin, ListView):

    model = Pagos
    table_class = PagosDetailTable
    template_name = 'AC/paymentsbycarandweek.html'
    paginate_by = 10

    def get(self, request, *args, **kwargs):
        self.object_list = self.get_queryset()
        self.object_list = self.object_list.filter(
            carro=kwargs['carro'], semana=kwargs['semana'])

        context = self.get_context_data()
    return self.render_to_response(context)

class Pagos(models.Model):

    carro = models.ForeignKey(
        Carros, on_delete=models.CASCADE, blank=False, null=False)
    pago = models.DecimalField(max_digits=6, decimal_places=2)
    fecha = models.DateField(
        auto_now=False, auto_now_add=False, blank=True, null=True)
    semana = models.CharField(max_length=20)
    startweek = models.DateField(
        auto_now=False, auto_now_add=False, blank=True, null=True)
    endweek = models.DateField(
        auto_now=False, auto_now_add=False, blank=True, null=True)
    renta = models.ForeignKey(
        Renta, on_delete=models.PROTECT, blank=False, null=False)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name_plural = "Pagos"

    def get_absolute_url(self):
        return reverse('pagos')

    def __str__(self):
        return self.semana

path('paymentsbycarandweek/<int:carro>/<slug:semana>',
         views.PagosDetailView.as_view(), name='pagos_bycar')

class PagosDetailView(SingleTableMixin, ListView):

    model = Pagos
    table_class = PagosDetailTable
    template_name = 'AC/paymentsbycarandweek.html'
    paginate_by = 10

    def get(self, request, *args, **kwargs):
        self.object_list = self.get_queryset()
        self.object_list = self.object_list.filter(
            carro=kwargs['carro'], semana=kwargs['semana'])

        context = self.get_context_data()
    return self.render_to_response(context)
