管理 gem 自定义用于仪表板集合中资源的标签

大佬教程收集整理的这篇文章主要介绍了管理 gem 自定义用于仪表板集合中资源的标签，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决管理 gem 自定义用于仪表板集合中资源的标签？

administrate gem guide 表示资源的标签可以适应该模型的属性

def display_resource(user)
  user.name
end

然而这似乎对关系不起作用

Cardbelongs_to User，目标是用

card.user.last_name + ',' + card.user.first_name

然而，即使是一个简洁的定义

def display_resource(user)
  card.user.last_name
end

导致undefined local variable or method 'card' for #<CardDashboard

似乎 display_resource 定义只适用于它自己的类

def display_resource(user)
  user.last_name + ',' + user.first_name
end

会起作用。

是否有一种机制可以使用嵌套属性在每个类的基础上定义资源标签？
