django - 管理员内联 one2one 字段

Question

我有三个 django 模型，我想在订单页面上编辑项目的实例。可能吗？

#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...

Answer 1

让它成为购物车的内联，而不是相反？
