在Django设置学年或财政年度

考虑使用自定义queryset

class CustomQuerySet(models.QuerySet):
    def current_financial_year(self):
        return self.filter(datefield__gte=current_finyear_start, datefield__lte=current_finyear_end)

CustomManager = models.Manager.from_queryset(CustomQueryset)

# Then in your model:

class MyModel(models.Model):
    objects = CustomManager()

#use it like this:
MyModel.objects.current_financial_year().filter(...)
MyModel.objects.current_financial_year().get(...)
