[Django]-Django best practices regarding custom User models

A custom user model is a good practice when you have to add new fields or logic to the User model (such as loging in using email instead of username or adding new permisions).
If you application is simple and you dont have to add new fields, you can use the default user model.
Other solution is to keep the user model intact and create an "User Profile" model with a OneToOne relation to User, but you would have to create the profile manually and add it to the User, or maybe use django signals to create an User profile every time a new user is created.
I personaly don’t recommend this last solution.
So, you should create a custom User model if you have to add new fields or logic, otherwise stick to the Default User Model.
If you use a custom model remember to add the new fields to the admin site
This is an example

    class User(AbstractUser):
        worker = models.OneToOneField(WorkerModel, on_delete=models.CASCADE, 
                    related_name="user", verbose_name=_("Trabajador"), null=True, blank=True)
    
        job = models.CharField(verbose_name="Cargo",max_length=50, null=True, blank=True)
        department = models.CharField(verbose_name="Departamento",max_length=50, null=True, blank=True)
        avatar = models.ImageField(verbose_name="Imagen", upload_to="user_avatar",
                                                    null=True, blank=True)
        class Meta:
            default_permissions = ()
            verbose_name="Usuario"
            verbose_name_plural="Usuarios"
            permissions = (
                ("secretario", "Secretario(a)"),
                ("director", "Director"),
            
            )

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import User #, UserProfileModel
from django.utils.translation import gettext, gettext_lazy as _

class UserAdminInherited(UserAdmin):
    autocomplete_fields = ['worker']
    fieldsets = (
        (None, {'fields': ('username', 'password')}),
        (_('Personal info'), {'fields': ('first_name', 'last_name', 'email','job','department','avatar')}),
        (_('Worker info'), {'fields': ('worker',)}),
        (_('Permissions'), {
            'fields': ('is_active', 'is_staff', 'is_superuser', 'groups', 'user_permissions'),
        }),
        (_('Important dates'), {'fields': ('last_login', 'date_joined')}),
    )

admin.site.register(User, UserAdminInherited)
