Django-管理界面-允许为非超级用户创建用户

Question

I have the situation of permits the access to admin interfaces to three types of users: - Admin - Supervisor - Agent

It's a situation hierarchycal, the admin is one (the superuser) and it's creates the supervisors, and the supervisors create the agents.

All them can login to django admin with distincts authorizations.

The login has managed by 'django.contrib.auth' with the default model auth_user (.

     from django.contrib.auth.models import User

class Supervisor(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    e_mail = models.EmailField(max_length=60, db_column='E-Mail',blank=True)
   ...other fields....


class Admin(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    e_mail = models.EmailField(max_length=60, db_column='E-Mail',blank=True)
     ...other fields...

But, there is a problem. If I allow the supervisor to create an agent implies that I must add the authorization to ADD and CHANGE the table USER. And this is dangerous, any supervisors could become a superuser, deleting users, etc etc....

How can I resolve this problem?? Is it possible to permit the supervisor to create an Agent without that he can be dangerous??

Thanks

EDIT

I have a doubt... in models.py during a definition of class I written this method:

def save(self):
    self.user.is_staff = True
    self.user.save()
    super(Agent, self).save()

In Java, the method of EJB it was transactional/atomic (the commit is automatic)... In django, I have to call the method save().

It is a question different from the previous.....

Don't know if I got to understand your problem. But, if I did, you could edit the user creation form.

@admin.register(User)
class UserAdmin(BaseUserAdmin):
    view_on_site = False
    list_display = ('username', 'first_name', 'last_name', 'is_active', 'is_staff', 'date_joined', 'last_login')
    list_filter = ('is_staff', )
    fieldsets = (
        ('Data', {'fields': ('username', 'email', 'first_name', 'last_name', 'password')}),
        ('Activation/Deactivation', {'fields': ('is_active', )}),
        ('Permissions', {'fields': ('is_staff', 'groups', )})
)

As superuser is not an option anymore, your supervisors can't became superusers.

Let me know if this helps. Maybe we can get closer to the solution.
