Kaminari는 상속 된 리소스를 사용합니까?

Kaminari 보석이 상속 된 리소스로 작동하는지 여부를 아는 사람이 있습니까? 코드를 건조하게 유지하려고하고 반복하지 않으려 고하기 때문에?Kaminari는 상속 된 리소스를 사용합니까?

계획은 하나의 부분을 사용하여 오류 테이블, 메시지 테이블 및 구독자 테이블의 3 가지 테이블을 렌더링하는 것입니다. 그러나 상속 된 리소스를 사용하기 때문에 오류 컨트롤러, 메시지 컨트롤러 및 구독자 컨트롤러에서 사용할 모든 코드가 Admin Application Controller를 통해 필요합니다.

흠, 아마 이것은 아마도 Kaminari와 관련이 없지만 데이터베이스 결과가 아마도 nil로 되돌아 올 가능성이 있으며 Kaminari가 현재 페이지를 호출하여 오류를 일으키는 것으로 추측하고 있습니다. 스택 추적도 제공 할 수 있습니까? 내가 작성한 애플리케이션에서 완벽하게 작동하는 답을 얻었습니다. – Rtype

페이지 매김 메서드를 어디서 호출할까요? <% = paginate @errors %> 또한 컨트롤러가 반환하는 콜렉션이 nil이 아닌지 확인할 수 있습니까? 아마도 상속 된 리소스를 사용하여 컨트롤러가 제대로 작동하는지 확인하기 위해 컨트롤러를 만드는 것이 좋습니다. – Rtype

예 테이블 부분에서 호출 중입니다 (게시 된 코드에 표시되지 않습니다). –

: 이 오류로 인해 CURRENT_PAGE 오류로 던져졌다 가능 :

class ProjectsController < InheritedResources::Base 
    protected 
    def collection 
     @projects ||= end_of_association_chain.page params[:page] 
    end 
end

~~아직 시도 할 기회가 없지만.~~

나는 이것을 테스트했으며 완벽하게 작동합니다.

감사의 말을 전합니다. –

지금까지 효과가 없습니다.내가 정의하지 않은 메소드 'current_page'에 nil이있다. NilClass –

코드 예제를 게시 할 수 있겠습니까? – Rtype

Kaminari는 상속 된 리소스를 사용합니까?
