I use the latest django for an intranet project. Well, I followed the django documentation to extend my models:

from django.db import models
from django.contrib.auth.models import AbstractUser
class Employee(AbstractUser):

DEPARTMENTS = (

(‘ARE’, ‘Area Manager’),

(‘IT’, ‘IT’),

(‘CAT’, ‘Category manager’),

(‘CON’, ‘Controling’)

)

departement = models.CharField(max_length = 3, verbose_name = “Département”, choices = DEPARTMENTS)

After that, I rewrited the admin.py:

from django.contrib import admin

from django.contrib.auth.admin import UserAdmin as BaseUserAdmin

from django.contrib.auth.models import User

from .models import Employee
Define an inline admin descriptor for Employee model
which acts a bit like a singleton
class EmployeeInline(admin.StackedInline):

model = Employee

can_delete = False

verbose_name_plural = ‘Employees’
Define a new User admin
class UserAdmin(BaseUserAdmin):

inlines = (EmployeeInline,)
Re-register UserAdmin
admin.site.register(User) # return error: django.contrib.admin.sites.NotRegistered: The model User is not registered
admin.site.unregister(User)

admin.site.register(User, UserAdmin)

As you can see on the 3 last line of my admin.py, if I register User model I have an error. If I comment my last lines

# Re-register UserAdmin

#admin.site.unregister(User)

admin.site.register(User, UserAdmin)

I haven’t my User administration: 

#python #django
