Rails：如何使用polymorphic_path动态为单个嵌套资源创建路径

Question

I have some singular nested resources and the entries for them looks like this:

resources :rocs, only: [:show] do
  resource :r1_response, :r2_response, :r3_response, :r4_response :r5_response do
    member do
      get :print
    end
  end
end

Now I want to dynamically generate paths for my nested singular resources like below:

print_roc_r1_response_path
print_roc_r2_response_path
...

I am trying to use polymorphic_path to generate above paths:

link_to "Print ROC", polymorphic_path([:print, @roc, controller.controller_name])

But it's giving error: undefined method print_roc_r1_responses_path cause controller.controller_name is plural . How do I fix it?

Answer 1

resources :rocs, only: [:show] do
  resources :r1_response, :r2_response, :r3_response, :r4_response :r5_response do
    member do
      get :print
    end
  end
end

Change resource to resources
