管理 gem指南 表明资源标签可以适应该模型的属性
def display_resource(user)
user.name
end
但是，这似乎不适用于关系
Card属于_to User ，目标是在 CardDashboard 中代表资源用户
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
看来 display_resource 定义只适用于它自己的类
def display_resource(user)
user.last_name + ', ' + user.first_name
end
将工作。
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？
