Question

我正在从youtube教程中建立一个电子商务网站，但遇到一个错误，确实使我感到困惑。

我尝试了google，但没有成功。然后我尝试弄乱Django，但这使情况变得更糟，所以我改了回去。

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)

完整的错误消息是这样的：

Answer 1

它是 ModelAdmin ，而不是 Modeladmin 。 docs

Answer 2

尝试以此方式更新您的代码：

from django.contrib import 
admin.ModelAdmin as admin

然后

class profileadmin(admin):

您可以在https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.readonly_fields

上找到有关django导入的更多信息。

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):

Django模型无法正常工作：模块'django.contrib.admin'没有属性'Modeladmin'
