Django and Python Error: has no attribute '_meta

Using Django Mystery Errors
1

I am working on Django for Beginners newsletter project and I have the following error message.
Traceback message:

AttributeError: type object 'CustomUserAdmin' has no attribute '_meta'

So the last line there in the traceback that says my class customuser admin says attribute has no meta. I think that makes since because there isn’t a class for Meta specified. So do I just create a Meta class?
admin.py

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

""" The final step is to update our admin.py file since the admin is tightly coupled to the default
User model. We will extend the existing UserAdmin class to use our new CustomUser model.
To control which fields are listed, we use list_display. But to actually edit new custom fields,
like age, we must add fieldsets. And to include a new custom field in the section for creating a
new user we rely on add_fieldsets.""" 
# 
# Register your models here.
from .forms import CustomUserCreationForm, CustomUserChangeForm
from .models import CustomUser

class CustomUserAdmin(UserAdmin):
    add_form = CustomUserCreationForm
    form = CustomUserChangeForm
    model = CustomUser
    list_display = [
        "email",
        "username",
        "age",
        "is_staff",
    ]
    fieldsets = UserAdmin.fieldsets + ((None, {"fields": ("age",)}),)
    add_fieldsets = UserAdmin.add_fieldsets + ((None, {"fields": ("age",)}),)

admin.site.register((CustomUser, CustomUserAdmin))

I am thinking that all I need to do is create a class Meta. Am I on the right track? Right now I am checking Django Forum and stack overflow for solutions.

Following line in your code is incorect:

admin.site.register((CustomUser, CustomUserAdmin))

Epected form is:

admin.site.register(CustomUser, CustomUserAdmin)
