Django admin，list_editable中的外键字段

Hi fellow django users,

嗨其他django用户,

How can I add a field from a related object in the list_editable admin property?

如何在list_editable admin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

I tried it this way, but it won't work. I also tried to add a property in the Product class, but nope, it won't work either. Any clue?

我试过这种方式,但它不起作用。我也尝试在Product类中添加一个属性,但是nope,它也不起作用。任何线索?

Thanks.

From the documentation:

从文档:

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

list_editable以特定方式与其他几个选项进行交互;你应该注意以下规则:

1. Any field in list_editable must also be in list_display. You can't edit a field that's not displayed!

list_editable中的任何字段也必须位于list_display中。您无法编辑未显示的字段!

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.

list_editable和list_display_links中不能列出相同的字段 - 字段不能同时是表单和链接。

3. You'll get a validation error if either of these rules are broken.

如果这些规则中的任何一个被破坏,您将收到验证错误。

Notice that you use *order_reference* and *order__reference* in list_display and list_editable, respectively. So in short, I don't think you can do this easily. If you want to have inspiration, you could check out the implementation of pageadmin.py in django-cms, but it's NOT straightforward!!

请注意,您分别在list_display和list_editable中使用* order_reference *和* order__reference *。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django-cms中pageadmin.py的实现,但这并不简单!
