결과는 다음 HTML입니다. (@ post에는 15 개의 항목이 있는데 각 항목에는 한 줄짜리 설명이 있지만 15 개의 설명 모두가 각 항목에 인쇄됩니다.)

index.html.haml도 변경해 보았습니다.

- content_for :main_content do 
    - @posts.each do |post| 
     = render :partial => "post_brief", :layout => "post_wrapper", :locals => {:post => post}

하지만 해당 심지어 미쳤 행동의 원인 - 첫 번째 항목이 하나 설명을했다, 두 번째는 두 가지가 있고, 등

무슨 일이야?

주어진 렌더링 과정에서 content_for 도우미를 여러 번 호출하면 해당 내용을 덮어 쓰지 않고 연결하여 여기에 표시되는 동작을 유도합니다. post_brief + post_wrapper를 단일 부분으로 바꾸고 부분 레이아웃을 사용하는 대신 렌더링하는 것이 좋습니다.

아, 내 말이 맞는 것 같아요. (당신이 content_for의 중간에 약간의 논리를해야한다면 두 곳에서'content_for '를 지정하기를 원합니다). 좋아요, 제가 할게요. post_brief와 post_wrapper를 분리하는 이유는 show.html.haml도'_post_wrapper'에서 같은 것을 사용했기 때문입니다.하지만 문제가있는 것 같습니다. – unsorted

그럴 경우, 이들을 헬퍼 나 재사용을위한 작은 별도의 부분으로 분해 할 수 있습니다. –
