Setting Academic or Financial Years in Django

问题

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

回答1:

consider using a custom queryset

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

then make a manager out of it

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(...)
