Ruby on rails ActiveRecord:：ActsAs路由问题

将旧的Rails 3应用程序升级到Rails 4，多表继承gem已因不推荐而更改。现在，使用

嵌套路由不工作，产生以下错误：

undefined method `vehicle_path' for #<#<Class:0x007f0e2778da70>:0x007f0e26725778>

父类：

class Vehicle < ActiveRecord::Base
  actable
end

class Vehicles::Car < ActiveRecord::Base
  acts_as :vehicle
end

namespace :vehicles do
  resources :cars, except: [:index]
end

任何帮助都将不胜感激

更新：Rake路由

vehicles          GET    /:locale/vehicles(.:format)                  vehicles#index {:locale=>/en|es/}

vehicles_cars     POST   /:locale/vehicles/cars(.:format)             vehicles/cars#create {:locale=>/en|es/}

new_vehicles_car  GET    /:locale/vehicles/cars/new(.:format)         vehicles/cars#new {:locale=>/en|es/}

edit_vehicles_car GET    /:locale/vehicles/cars/:id/edit(.:format)    vehicles/cars#edit {:locale=>/en|es/}

vehicles_car      GET    /:locale/vehicles/cars/:id(.:format)         vehicles/cars#show {:locale=>/en|es/}

                  PATCH  /:locale/vehicles/cars/:id(.:format)         vehicles/cars#update {:locale=>/en|es/}

                  PUT    /:locale/vehicles/cars/:id(.:format)         vehicles/cars#update {:locale=>/en|es/}

                  DELETE /:locale/vehicles/cars/:id(.:format)

什么输出为您提供了

rake路由

？@AlejandroMontilla，已更新。谢谢。您可以尝试使用类似于

%td=link\u to vehicle.code，vehicles\u path（vehicle，@car）

的方法，其中

@car

是要显示的汽车的外观。“vehicle”是对象的实例。此车辆可能是一辆汽车或其他东西。您是否尝试过使用

%td=link\u to vehicle.code，vehicles\u car\u path（vehicle）
