我的自定义方法webshops#reset从未真正从 中调用webshops_controller，因为它不Webshop存在任何对象。相反，我有子类PrestashopWebshop，如MagentoWebshop, 等。

Myapp::Application.routes.draw do

  ...

  resources :webshops
  resources :magento_webshops
  resources :prestashop_webshops

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

  ...

end

以下是来自子类控制器的方法。

class MagentoWebshopsController < WebshopsController

  def scoped_webshops
    "magento_webshops"
  end
end

当我从子类控制器magento_webshops_controller中调用index我可以访问的操作时scoped_webshops。但是当我调用自定义方法时，reset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，我该如何调用api/webshop/:id/reset（所有子类都使用相同的通过ajaxwebshops.js.coffee调用）？reset我猜整个问题是由webshops_controller直接工作引起的，而没有从子类调用它的动作。然而，第一行 ( webshop = Webshop.find(params[:id])) 应该以某种方式让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

从继承的资源文档：

从 1.2 版开始，Inherited Resources 允许您在控制器中定义自定义操作：

class ButtonsController < InheritedResources::Base
  custom_actions :resource => :delete, :collection => :search
end

此代码在控制器中创建删除和搜索操作（它们的行为类似于相应的显示和索引操作）。此外，它还会生成delete_resource_{path,url} 和search_resources_{path,url}url 助手。
