Ruby on rails 基于helper变量将link_更改为path

我有一个助手方法，我想用于几个模型，以避免重复相同的代码多次

def link_to_follow(instance:instance,type:type)
  link_to('Unfollow', unfollow_books_path(id: instance.id), 
          method: :post, 
          id: "unfollow_link_#{instance.id}",
          remote: true)
end

---

我如何做才能使如果我将

键入：'magazine'

作为变量传递，那么

unfollow\u books\u path

将变成

unfollow\u magazies\u path

def link_to_follow(instance:instance, type:type)
  link_to(
    'Unfollow', 
    send("unfollow_#{type.pluralize}_path", instance), 
    method: :post, 
    id: "unfollow_link_#{instance.id}",
    remote: true
  )
end  

我想你也可以做到：

def link_to_follow(instance:instance)
  link_to(
    'Unfollow', 
    send("unfollow_#{instance.class.name.underscore.pluralize}_path", instance), 
    method: :post, 
    id: "unfollow_link_#{instance.id}",
    remote: true
  )
end

啊!！这是有道理的。谢谢！
