Hi There!
Starting out with Django, and was looking for a bit of guidance. I am
trying to establish a Organizational structure for employee/supervisor
type relationships. Since each of these individuals will be a user, I am
extending trying to also take advantage of django's built-in
contrib.auth package.
In Short, employees report to supervisors, and in turn supervisors in
themselves can report to their respective supervisors... I developed the
following models, but was curious if there might be a better way to do this:
There will be a few different opinions on this ... here's mine:
class Employee(models.Model):
user = models.ForeignKey(User)
def __unicode__(self):
return self.user.username
class Relationship(models.Model):
boss = models.ForeignKey(Employee)
worker = models.ForeignKey(Employee)
relationship_type = models.CharField(max_size=32)
def __unicode__(self):
return "{0} {1} {2}".format(boss, relationship_type, worker)
I just typed this without testing and I think you would need to read up
on 'related_name' and use null=True here and there to get it working.
I would choose this approach to get some flexibility with multiple
relationships between employees. Supervisors get supervised too. Also, I
might choose different field names than "boss" and "worker" if I was
doing this for myself.

class Supervisor(models.Model):
supervisor = models.OneToOneField(User)
def __unicode__(self):
return self.supervisor.username
class Employee(models.Model):
employee = models.OneToOneField(User)
supervisor = models.ForeignKey(Supervisor)
def __unicode__(self):
return self.employee.username
Thank you!
