我在 django 中有一些存檔日期在我的視圖中這樣定義class OfferingMonthArchiveView(MonthArchiveView):
queryset=Offering.objects.all()
date_field="date"
allow_future=True使用上面的類方法調用 url 中的類有點棘手path('<int:year>/<int:month>/',views.OfferingMonthArchiveView.as_view(month_format='%m'),name="month-archive"),但它似乎確實有效，它不斷帶來一些錯誤

OP 可能意味著cv2.COLOR_BGR2GRAY.
根據OpenCV 文檔，該cv2包沒有cv2.COLOR_BRG2GRAY.?請參閱可用顏色轉換代碼的鏈接。
為了完整起見，這里是鏈接中的相關內容：

這解決了，我添加了一個引用存檔視圖的輔助功能
class MonthlySum(RedirectView):
def get_redirect_url(self, *args, **kwargs):
today = timezone.now()
return reverse(
'month-archive',
kwargs={
'month': today.month,
'year': today.year,
}
)
在網址中
path('offering/report/<int:year>/<int:month>/',views.OfferingMonthArchiveView.as_view(),name="month-archive"),
