I created a custom user model using the AbstractUser class, without including either the password or usable\_password field. However, I encountered the following error in the admin panel when I try to add a new user;
_FieldError at /admin/accounts/customuser/add/_
_Unknown field(s) (usable\_password) specified for CustomUser. Check fields/fieldsets/exclude attributes of class CustomUserAdmin._
After investigation, I discovered that the culprit — usable\_password — had been automatically added to the default ‘UserAdmin’ class.
This leads me to the following questions:
1. Why does my CustomUser model appear to inherit the usable\_password field?
2. Why does the AbstractUser/AbstractBaseUser class include usable\_password, even though it is not a legitimate model field?
3. Why is the UserAdmin class attempting to register the default User model, even though my CustomUserAdmin class explicitly defines the fields as:
```auto
class CustomUserAdmin(UserAdmin):
add_form = CustomUserCreationForm
form = CustomUserChangeForm
model = CustomUser
list_display = ["username", "email", "is_staff", "age"]
fieldsets = UserAdmin.fieldsets + ((None, {"fields": ("age",)}),)
add_fieldsets = UserAdmin.add_fieldsets + ((None, {"fields": ("age",)}),)
admin.site.register(CustomUser, CustomUserAdmin)
```

Show the code for your custom user - please format code correctly with ``` on a line before and after the code.
Also show the value of `AUTH_USER_MODEL` from your `settings.py`

Thanks for the heads-up on how to properly format a code. Here is the code for custom user:
```auto
from django.db import models
from django.contrib.auth.models import AbstractUser
class CustomUser(AbstractUser):
age = models.PositiveIntegerField(null=True, blank=True)
```
From settings:
```auto
AUTH_USER_MODEL = "accounts.CustomUser"
```

Thank you, I’ll take a look.
