레일스 - Railscast에서 간단한 검색이 표시되지 않음

Question

URL 변경 사항을 검색 할 때마다 간단한 검색 양식을 만드는 방법에 대한 railscast 자습서 ( )를 따라 왔으며 서버 로그가 이 경우에는 광고를 게재하지만 게재되지는 않습니다.

는 어떤 도움을 크게 감상 할 수있다.

Answer 1

ad.size에서 검색 가능한 광고를 확인하십시오. 크기가 "추천"또는 "보통"이 아닌 경우보기가및 ad.size == "medium"의 유일한 if 조건이므로 무시됩니다.

<% @ads.inspect %> 

또한

, @ads_small, @ads_medium 및 @ads_featured 어디서나 사용할 수 있도록 표시되지 않습니다 :

당신은 검색에 의해 발견되는 것을보고 싶다면

는 이것을 <% @ads.each do |ad| %> 라인 위의 라인을 포함한다. 그것들은 미래의 목적을위한 것입니까?
