我正在为初学者开发Django，我有以下错误消息。

字符串
回溯的最后一行说我的类customuser admin说attribute没有Meta。我认为这是因为没有为Meta指定类。那么我只需要创建一个Meta类吗？
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))

型
我重新看了一下说明书。我查看了Stack Overflow文章。我在Discord上给人们发信息
我正在学习如何在Django中创建一个Meta类。我正在搜索Django论坛以获取更多信息。
