Design Django Admin For Specific Model

Using Django auth UserAdmin for a custom user model


from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.utils.translation import gettext_lazy as _
from .models import *

class PortalAdmin(UserAdmin):
    fieldsets = (
        (None, {'fields': ('username', 'password')}),
        (_('Personal info'), {'fields': ('first_name', 'last_name', 'email', 'mobile_number', 'portal_site',
                                         'portal_node')}),
        (_('Permissions'), {'fields': ('is_active', )}),
        (_("Role"), {'fields': ('is_superuser', 'is_site_user', 'is_portal_user')}),
        (_('Important dates'), {'fields': ('last_login', 'date_joined')}),
    )

    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('username', 'password1', 'password2')}),)

    list_display = ('username', 'email', 'first_name', 'last_name', 'mobile_number',
                   'is_superuser', 'is_site_user', 'is_portal_user')
    list_filter = ('is_active', 'is_superuser', 'is_site_user', 'is_portal_user',)
    search_fields = ('username', 'first_name', 'last_name', 'email', 'mobile_number', 'portal_site','portal_node')
    ordering = ('username',)

admin.site.register(PortalUsers, PortalAdmin)


after added in setting - AUTH_USER_MODEL = 'users.CustomUser'

 then 

(env)$ python manage.py makemigrations
(env)$ python manage.py migrate
if you face import model error, if you use forigenkey relation then you will replace settings.AUTH_USER_MODEL and import setting file as well.

 then again run migrations.
