在Django中设置学术或财务年度 [英] Setting Academic or Financial Years in Django

问题描述

这似乎微不足道，但是您如何在Django模型中设置财务年度或学年，例如2018/19或2017/2018，并参考当前财务年度进行查询，在这种情况下为2019/20

This may seem rather insignificant, but how do you set a financial or academic year, say 2018/19 or 2017/2018 in a Django model and reference the current financial year for querying, in this case 2019/20

推荐答案

考虑使用自定义查询集

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

然后从中选拔一个经理

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(...)
