Django 模型不工作：模块 'django.contrib.admin' 没有属性 'Modeladmin'

Question

我正在根据 youtube 教程制作电子商务网站，但我遇到了一个非常困扰我的错误。

我试过谷歌，但没有用。然后我尝试弄乱 Django，但结果变得更糟，所以我改回来了。

这是 admin.py 的代码：

from django.contrib import admin

# Register your models here.
from .models import profiles

class profileadmin(admin.Modeladmin):
    class Meta:
        model = profiles

admin.site.register(profiles, profileadmin)

完整的错误信息是这样的：

Answer 1

它是 ModelAdmin 而不是 Modeladmin。 docs

Answer 2

尝试像这样更新您的代码：

from django.contrib import 
admin.ModelAdmin as admin 

然后

class profileadmin(admin):

你可以在这里找到更多关于 django 导入的信息https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.readonly_fields

Answer 3

from django.contrib import admin

# Register your models here.
from .models import profiles

class profileadmin(admin.Modeladmin): #the error is in this line
    class Meta:
        model = profiles

admin.site.register(profiles, profileadmin)

The correct format suppose to be 
class profileadmin(admin.ModelAdmin):
