Question

我的自定义方法webshops#reset实际上从未从webshops_controller调用，因为它不存在Webshop个对象。相反，我有类似PrestashopWebshop，MagentoWebshop等的子类

Myapp::Application.routes.draw do

  ...

  resources :webshops
  resources :magento_webshops
  resources :prestashop_webshops

  get "api/webshop/:id/reset" => "webshops#reset"

  ...

end

以下是子类控制器的方法。

class MagentoWebshopsController < WebshopsController

  def scoped_webshops
    "magento_webshops"
  end
end

当我从magento_webshops_controller这样的子类控制器调用index操作时，我可以访问scoped_webshops。但是当我调用自定义方法reset时，我无法访问这些子类方法。

class WebshopsController < InheritedResources::Base
  respond_to :html, :json
  before_filter :authenticate_user!

  def index
    @webshops = current_user.send(scoped_webshops)
  end

  def reset
    webshop = Webshop.find(params[:id])
    @webshops = current_user.send(scoped_webshops)

    respond_to do |format|
      format.html {

      ...

      }
      format.js
    end
  end
end

那么，我如何调用api/webshop/:id/reset（所有子类使用相同的webshops.js.coffee通过ajax调用reset？我想整个问题是由webshops_controller直接工作而没有从子类调用它的动作引起的。但是，第一行（webshop = Webshop.find(params[:id])）应该以某种方式使我们能够确定应该使用哪个子类，因为它返回一个子类对象......

这可能有效：

class WebshopsController < InheritedResources::Base
  custom_actions :resource => :reset

来自inherited_resources docs：

从1.2版开始，Inherited Resources允许您定义自定义控制器中的动作：
class ButtonsController < InheritedResources::Base
  custom_actions :resource => :delete, :collection => :search
end
此代码创建删除和搜索控制器中的操作（它们的行为类似于show和因此指数行动）。此外，它将产生delete_resource_{path,url} 和search_resources_{path,url}网址助手。

如何从子控制器访问方法 - 从一开始 - 知道哪个子控制器？
