Django：更新时如何发送两个pk？

当我更新与moneybook相关的moneylog时，出现以下错误：

NoReverseMatch at/moneylogs/update/8/ 未找到参数为“（“”，8）”的“delete”的反转。尝试了1个模式：[“moneylogs/（？P[0-9]+）/delete/（？P[0-9]+）/$”]

我猜这是因为没有moneybook.pk，但我不知道如何处理

谁能帮我一下吗？ 型号.py

 class Moneylog(core_models.TimeStampedModel):

        moneybook = models.ForeignKey(
            moneybook_models.Moneybook, on_delete=models.CASCADE)
        pay_day = models.DateTimeField(default=NOW)
        payer = models.ForeignKey(
            tempfriend_models.Tempfriend, on_delete=models.CASCADE, related_name="payer")
        dutch_payer = models.ManyToManyField(
            tempfriend_models.Tempfriend, related_name="dutch_payer", blank=True)
        price = models.IntegerField()
        category = models.CharField(max_length=10)
        memo = models.TextField()

    model = moneylog_models.Moneylog

        moneybook = moneybook_models.Moneybook.objects.get(
            pk=moneylog.moneybook.id)
        moneylog.save()
        form.save_m2m()
        return redirect(reverse("moneybooks:detail", kwargs={'pk': moneybook.pk}))

路径（“创建/”，
views.moneylog\u create.as\u view（），name=“create”），
路径（“更新/”，
views.moneylog\u update.as\u view（），name=“update”），
路径（“/delete/”，
views.moneylog_delete，name=“delete”），
]

模板（moneylog\u Form\u update.html）

。。。
{{cta}}

改为

<a href="{% url 'moneylogs:delete' moneylog.moneybook_id moneylog.pk %} " >

因为你在moneylog的更新页面上

然而，传递moneybook\u id实际上根本不需要这样做，因为moneylog总是有它，所以

moneylog

实例足以确定它链接到哪个moneybook
