Ruby on rails 获取ActionController:：RoutingError当路由列在Rake路由的输出中时

我有

Drill

和

Exercise

模型。练习属于训练，我有routes.rb，其中包括：

resources :drills do
    resources :exercises do
end

因此，从rake路由中看到这种输出并不奇怪：

drill_exercises GET    /drills/:drill_id/exercises(.:format)                                      exercises#index
                              POST   /drills/:drill_id/exercises(.:format)                                      exercises#create
           new_drill_exercise GET    /drills/:drill_id/exercises/new(.:format)                                  exercises#new
          edit_drill_exercise GET    /drills/:drill_id/exercises/:id/edit(.:format)                             exercises#edit
               drill_exercise GET    /drills/:drill_id/exercises/:id(.:format)                                  exercises#show
                              PUT    /drills/:drill_id/exercises/:id(.:format)                                  exercises#update
                              DELETE /drills/:drill_id/exercises/:id(.:format)                                  exercises#destroy

令人惊讶的是，这一行代码：

<%= link_to t('.new', :default => t("helpers.links.prompt")),
      new_drill_exercise_path,
      :class => 'btn btn-primary', :remote => true %>

没有路由匹配{:action=>“new”，:controller=>“exercises”}

尽管我在IRB中调用controller.methods时得到的结果之一是

：new\u drill\u exercise\u path

所以。。。怎么回事

更多信息：

练习u controller.rb

class ExercisesController < InheritedResources::Base
  def new
    @drill = Drill.find(params[:id])
    @exercise = Exercise.new
    respond_to do |format|
      format.html { redirect_to(:action => 'edit')  }
      format.js 
    end 
  end
end

class ExercisesController'edit'）}
format.js
结束
结束
结束

您缺少路径所需的

钻取id

。尝试：

new_drill_exercise_path(@drill)

或：

---

该死的，你说得对！我一直在想，方法的名称会自动神奇地将钻孔对象拉入。

new_drill_exercise_path(@drill)

new_drill_exercise_path(params[:id]) # assumes this is inside `DrillsController#show` or similar
