UPDATE 1 :

덕분에 오류가 forms.html.erb

코드의이 부분에 참으로 보이는 언급 j03w하기

Answer 1

J03w는 권리입니다. select_tag의 옵션에 전달하는 @ 변수와 관련이있는 것 같습니다.

나는 알아낼 수 없었지만 선택 목록 옵션을 만들기 위해 루비 각 루프를 사용하여 잘 작동하는 대안을 생각해 냈습니다.

<ul> 
    <li> 
     <label>Dropdown with search:</label> 
     <select name="color-search" id="color-search" class="chzn-select"> 
      <% @colorList.shuffle.each do |color| %> 
       <option value="<%= color %>"><%= color %></option> 
      <% end %> 
     </select> 
    </li> 

    <li> 
     <label>Dropdown menu:</label> 
     <select name="colors" id="colors" class="uniform"> 
      <% @colorList.shuffle.each do |color| %> 
       <option value="<%= color %>"><%= color %></option> 
      <% end %> 
     </select> 
    </li> 
</ul> 

나는 거 내가 당신의 처음 문제를 알아낼 수 있지만 희망이 당신이 그 동안 다른 것들로 이동하는 데 도움이 있는지 확인하기 위해 주위를 계속 연주 해요.

업데이트 1 : 중개인이 select_tag의 options 매개 변수에 배열을 전달하는 것이 좋지 않은 것처럼 보입니다. select_tag의 options 매개 변수는 이상이 없으므로 정상적으로 작동해야합니다. 처음에는 @colorList에 저장되는 배열의 데이터라고 생각했지만 모두 체크 아웃했습니다.

심지어 middleman docs에 사용 된 예제로 단순화하려고 시도했지만 여전히 nil String 오류가 발생했습니다. 나는 혼란 스럽다.

아마 중개인 (나는 3.1.4를 사용하고있다)의 최신 버전에 대한 문제가 있습니까?
