왜 current_page가 맞습니까? 완전히 관리되는 리소스에서 수행 할 때 'no route error'를 반환합니까?

Question

나는 다음과 같은 경로있다 :

resources :profiles do 
    member do 
     patch :speed_rating 
     patch :dribbling_rating 
     patch :passing_rating 
     patch :tackling_rating 
     post :favorite 
     post :unfavorite 
    end 
    collection do 
     get :autocomplete 
    end 
    end 

나는에 관심이 다음 경로 생성,이 내 application.html.erb에서

# truncated for brevity 
profiles_path GET /profiles(.:format) profiles#index 

profile_path GET /profiles/:id(.:format) profiles#show 

있습니다

<% if current_page?(controller: "profiles", action: "show")%> 
     <div id="page-wrapper" class="gray-bg"> 
    <% else %> 
     <div id="page-wrapper" class="image-bg"> 
    <% end %> 

언제 I 내 Profiles#Show으로 가면 제대로 작동하지만 내 Profiles#Index (일명 my root_path)로 이동하면 다른 것을 얻을 수 있습니다. 기록을 위해 편집 한

ActionController::UrlGenerationError - No route matches {:action=>"show", :controller=>"profiles"}: 

, 문제없이 다음과 같은 작품 : 그것은 url_for 사용하면 current_page?source code을 살펴 경우

<% if (controller_name.eql? "profiles") && (action_name.eql? "show") %> 

Answer 1

당신이 생각하는 것, 어떤 URL을 만들고 주소 표시 줄에 표시된 것과 일치하는 유효한 옵션이 실제로 필요합니다.

url_for(controller: "profiles", action: "show")은 :id없이 해당 경로를 찾을 수 없습니다. current_page?(controller: "profiles", action: "show", id: 1)을 사용하면 오류가 발생하지 않습니다. 이 같은 다른 쿼리 문자열 매개 변수를 포함, 완벽하게 일치 테스트하기 위해 제작 되었기 때문에

current_page이 일에 대한 당신의 최선의 선택되지 않습니다 : 특정 경우

# http://www.example.com/shop/checkout?order=desc&page=1 
current_page?(controller: 'shop', action: 'checkout', order: 'desc', page: '1') 

, 당신은 일치하도록 싶습니다 show 액션을 렌더링하는 모든 페이지. 나는 당신이 편집 1에서 제시 한 해결책이 적합하다고 생각합니다. 당신이 그것을 청소하고 싶다면 당신은 당신의 도우미로 항상 감쌀 수 있습니다.
