从django admin list_display访问，这是One-To-One表中的值

Given a one-to-one extension a model, such as the Django User model:

给定一对一扩展模型，例如Django User模型：

class UserProfile(models.Model):
     user        = models.OneToOneField(User, related_name='profile', unique=True)
     avatar      = models.ImageField(_('Avatar'))
     foo         = models.CharField(max_length=100, verbose_name="xxx")

How can I display that in the admin?

如何在管理员中显示？

class UserAdmin(admin.ModelAdmin):
     list_display = ('email', 'profile__foo' <--NOT WORKING )

A near match question is Django Admin: How to display value of fields with list_display from two models which are in oneToOne relation?

The general method would be:

一般方法是：

class UseAdmin(admin.ModelAdmin):
    list_display = ('email', 'profile_foo')
    def profile_foo(self, x):
        return x.profile.foo
    profile_foo.short_description = 'foo'

x here is the object of the model you are displaying

x此处是您正在显示的模型的对象
