I have a model Staff and LeaveReportStaff, I wanted to get leave_balance
between Total_Leave_Days and leave_days. I already used Foreignkey for
staff but I'm not sure if it is right to use Foreignkey again.
Please advise the best way forward.
class Staff(models.Model):
Total_Leave_Days = models.PositiveIntegerField(default=0)
course = models.ForeignKey(Course, on_delete=models.DO_NOTHING,
null=True, blank=False)
admin = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
class LeaveReportStaff(models.Model):
staff = models.ForeignKey(Staff, on_delete=models.CASCADE)
start_date = models.DateField()
end_date = models.DateField()
leave_type = models.CharField(choices=LEAVE_TYPE, max_length=25,
null=True, blank=False)
@property
def leave_days(self):
return (self.end_date - self.start_date).days
@property
def leave_balance(self):
return (self.Total_Leave_Days - self.leave_days)
