Is it possible to make editable ForeignKey attribute in change list?
Every user has it's UserProfile object (OneToOneField). I want admin to be able to modify UserProfile expiry date from User change list. 
I can display the expiry in change list:
class UserCustomAdmin(UserAdmin):
    list_display = ['id', 'username','email', 'last_login','userprofile__expiracia']
    # list_editable = ['userprofile__expiracia']
    exclude = ['groups','user_permissions']
    inlines = [UserProfileInline]
    fieldsets = (
        (None, {'fields': ('username', 'password')}),
        (_('Personal info'), {'fields': ('first_name', 'last_name', 'email')}),
        (_('Permissions'), {'fields': ('is_active', 'is_staff', 'is_superuser',
                                       )}),
        (_('Important dates'), {'fields': ('last_login', 'date_joined')}),
    )
    def userprofile__expiracia(self,obj):
        return obj.userprofile.expiracia
But I can't add userprofile__expiracia to list_editable list. It raises:
<class 'dashboard.admin.UserCustomAdmin'>: (admin.E121) The value of 'list_editable[0]' refers to 'userprofile__expiracia', which is not an attribute of 'auth.User'.
How can I make it work?
