admin inline over one2one字段

Question

我有三個django模型，我想在訂單的頁面上編輯項目的實例。可能嗎？

#models.py 

class Item(models.Model): 
    name = models.CharField(max_length = 128) 
    cart = models.ForeignKey('Cart') 

class Cart(models.Model): 
    number = models.IntegerField() 

class Order(models.Model): 
    cart = models.OneToOneField('Cart') 

#admin.py 

ItemInline(admin.TabularInline): 
    model = Item 

CartInline(admin.TabularInline): 
    model = Cart 

Order(ModelAdmin): 
    inlines = (CartInline,) # I need ItemInline here...

是否這樣訂購是購物車的內聯，而不是其他方式？
