查找具有多种父类型的嵌套资源的父级

给出一个类似的模型:

class PhoneNumber < ActiveRecord::Base
  has_many :personal_phone_numbers
  has_many :household_phone_numbers
  has_many :organization_phones

  has_many :people, :through => :personal_phone_numbers
  has_many :households, :through => :household_phone_numbers
  has_many :organizations, :through => :organization_phones
end

在查看电话号码时,我可能会将其视为嵌套资源,因此控制器将具有一个参数项 person_id , household_id 或 organization_id

我需要风景 link_to "Return", ... 返回到我们从中找到电话号码的正确资源。我该怎么做?
