        for y in year:
            yea_to_days = self.year  # You already have it
            days_count = monthrange(int(yea_to_days),int(self.month))[1]
            self.day_count = days_count
        return self.day_count

  • def save(self, *args, **kwargs): month = MainMonth.objects.all().filter(main_year__MainYear__id=self.id).select_related('main_year') if MainMonth: for y in MainMonth.objects.all(): new_year = y.main_year.year print(70*'=') print("----------------->",new_year) for m in month: n_month =m.month print(70*'=') print(n_month) self.day_count = monthrange(int(new_year),int(n_month))[1] return super().save(*args,**kwargs) – abdoh elngar Nov 08 '22 at 10:52
