Creating a group hierarchy in Django - django

Question

I can't seem to figure out how to best implement a user model following this schema in Django:
All are members, some are staff and must be part of a committee, where each committee has a leader
I'm creating a custom admin interface for my use. I've extended the AbstractBaseUser class to create a new class User that represents all members, but there are some fields that are not relevant to members.
class User(AbstractBaseUser):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
username = models.CharField(max_length=20, unique=True)
date_joined = models.DateTimeField(auto_now_add=True)
email = models.EmailField(max_length=100, default='')
phone_number = models.CharField(default='', blank=True)
balance = models.IntegerField(default=0)
minimum_balance = models.IntegerField(default=0)
status = models.CharField(choices=STATUS, default=STATUS_ACTIVE)
committee = models.CharField(choices=COMMITTEE, default=COMMITTEE_1)
objects = MyUserManager()
USERNAME_FIELD = 'username'
EMAIL_FIELD = 'email'
REQUIRED_FIELDS = ['first_name',
'last_name',
'email',]
def get_full_name(self):
return "{0} {1}".format(self.first_name,self.last_name)
def get_short_name(self):
return self.first_name
def __str__(self):
return self.username
These fields are not needed by a regular member:
status = models.CharField(choices=STATUS, default=STATUS_ACTIVE)
committee = models.CharField(choices=COMMITTEE, default=COMMITTEE_1)
Should these fields be included in the User class and be part of a Group, or should they be somewhere else? How can a leader of a committee be represented in this Django model? Also, is there a better way to implement a hierarchy of users like this in Django?

Answer 1

You can create a modal for committee like this.
Class Committee(models.Model):
name = models.CharField(max_length=255, unique=True)
members = models.ManyToManyField(User)
leader = models.ForeignKey(User)
Above models depict there will not be multiple committees with the same name, a committee will have some members and one leader.
