在 Django 中命名存档日期

Question

我在 django 中有一些存档日期在我的视图中这样定义class OfferingMonthArchiveView(MonthArchiveView):   queryset=Offering.objects.all()   date_field="date"   allow_future=True使用上面的类方法调用 url 中的类有点棘手path('<int:year>/<int:month>/',views.OfferingMonthArchiveView.as_view(month_format='%m'),name="month-archive"),但它似乎确实有效，它不断带来一些错误

Answer 1

OP 可能意味着cv2.COLOR_BGR2GRAY.

根据OpenCV 文档，该cv2包没有cv2.COLOR_BRG2GRAY. 请参阅可用颜色转换代码的链接。

为了完整起见，这里是链接中的相关内容：

Answer 2

这解决了，我添加了一个引用存档视图的辅助功能

class MonthlySum(RedirectView):

def get_redirect_url(self, *args, **kwargs):

    today = timezone.now()

    return reverse(

        'month-archive',

        kwargs={

            

            'month': today.month,

            'year': today.year,

        }

    )

在网址中

path('offering/report/<int:year>/<int:month>/',views.OfferingMonthArchiveView.as_view(),name="month-archive"),
