當路由在列表路由的輸出中列出時獲取ActionController :: RoutingError

Question

我有模型Drill和Exercise。練習屬於鑽和我都用的routes.rb：

resources :drills do 
    resources :exercises do 
end 

因此，這並不奇怪，看看從耙路線的輸出：

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 

令人驚訝的是，這行代碼：

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

是造成此錯誤：

ActionController::RoutingError at /drills/6/edit 

沒有路由匹配{：動作=>「新」，：控制器=>「演習」}

儘管事實上，當我在打電話IRB一個controller.methods結果我得到的回覆是:new_drill_exercise_path

那麼......那是怎麼回事？

更多信息：

exercises_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 

Answer 1

你缺少所需的路徑drill_id。嘗試：

new_drill_exercise_path(@drill) 

或：

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