我的应用程序中有多种型号。但是，有一个我无法注册，因此可以在admin panel中看到它。
因此，在我的cart应用admin.py文件中，我可以使用：
from django.contrib import admin
from .models import Cart, CartItem
# Register your models here.
admin.site.register(Cart)
但不是：
from django.contrib import admin
from .models import Cart, CartItem
# Register your models here.
admin.site.register(Cart, CartItem)
因为出现此错误：

对于两种模型，您必须调用admin.site.register两次：
admin.site.register(Cart)
admin.site.register(CartItem)
答案 1 :(得分：2)
将您的admin.py编辑为
from django.contrib import admin
from .models import Cart, CartItem
# Register your models here.
admin.site.register(Cart)
admin.site.register(CartItem)
答案 2 :(得分：1)
或者您可以这样做：
admin.site.register([Cart, CartItem])
