Django admin，list_editable 中的外键字段

Question

大家好 django 用户，

如何在 list_editable 管理属性中添加相关对象的字段？

# models.py
class Order(Model):
    reference = CharField(max_length=25)

class Product(Model):
    name = CharField(max_length=50)
    order = ForeignKey(Order)

# admin.py
class ProductAdmin:
    list_display = ('name', 'order_reference')
    list_editable = ('name', 'order__reference') # <--- THIS !

    def order_reference(self, obj):
        return obj.order.reference

这个方法我试过了，不行。我还尝试在 Product 类中添加一个属性，但是不行，它也不起作用。有什么线索吗？

谢谢。

From the documentation :

list_editable interacts with a couple of other options in particular ways; you should note the following rules:

1. Any field in list_editable must also be in list_display. You can't edit a field that's not displayed!
2. The same field can't be listed in both list_editable and list_display_links -- a field can't be both a form and a link.
3. You'll get a validation error if either of these rules are broken.

请注意，您在 list_display 和 list_editable 中分别使用了 *order_reference* 和 *order__reference*。所以简而言之，我认为你不能轻易做到这一点。如果您想获得灵感，可以查看 pageadmin.py in django-cms 的实现，但这并不简单!!
