Roles in Django - django

Question

I'm creating web based system, where I have 5 or 6 different roles and access type. I made a research how to achieve this and everything is made only when create group in django admin and assign user into it but only from the administrative part. I need to create this from the views. I already have a form to add users with email and drop down menu to set the role type.
Any suggestions will be appreciated, because till now I don't have idea how to achieve this without to assign the users from django admin.
my model.py for users:
class CustomUserManager(BaseUserManager):
"""
Custom user model manager where email is the unique identifiers
for authentication instead of usernames.
"""
def create_user(self, email, password, **extra_fields):
"""
Create and save a User with the given email and password.
"""
if not email:
raise ValueError(_('The Email must be set'))
email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, password, **extra_fields):
"""
Create and save a SuperUser with the given email and password.
"""
extra_fields.setdefault('is_staff', True)
extra_fields.setdefault('is_superuser', True)
extra_fields.setdefault('is_active', True)
if extra_fields.get('is_staff') is not True:
raise ValueError(_('Superuser must have is_staff=True.'))
if extra_fields.get('is_superuser') is not True:
raise ValueError(_('Superuser must have is_superuser=True.'))
return self.create_user(email, password, **extra_fields)
class CustomUser(AbstractUser):
username = None
email = models.EmailField(_('email address'), unique=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
objects = CustomUserManager()
def __str__(self):
return self.email
ADMIN = 1
RECEPTION = 2
HEADOFDEPARTMENT = 3
EMPLOYEE = 4
PATIENT = 5
NOTACTIVE = 6
ROLE_CHOICES = (
(ADMIN, 'Admin'),
(RECEPTION, 'Reception'),
(HEADOFDEPARTMENT, 'HeadOfDepartment'),
(EMPLOYEE, 'Employee'),
(PATIENT, 'Patient'),
(NOTACTIVE, 'NotActive'),
)
role = models.PositiveSmallIntegerField(choices=ROLE_CHOICES, blank=True, default=True, null=True)
#email = models.EmailField(verbose_name="email", max_length=60, unique=True)
username = models.CharField(max_length=30, blank=True, default='')
is_superuser = models.BooleanField(default=True)
is_admin = models.BooleanField(default=True)
is_employee = models.BooleanField(default=True)
is_headofdepartment = models.BooleanField(default=True)
is_reception = models.BooleanField(default=True)
is_patient = models.BooleanField(default=True)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=True)

Answer 1

like this
from django.contrib.auth.models import Group
def ViewFunc(request):
... #your func
role = Group.objects.get(name='role')
role.user_set.add(user)
You retrieve the user object in the way you want in views, you add it in the user set in the group, done.
EDIT
Adding user Foo to Admins Group.
from django.contrib.auth.models import Group, User
def ViewFunc(request):
user = User.objects.get(username = 'Foo')
role = Group.objects.get(name='Admins')
role.user_set.add(user)
