보기에 HABTM 데이터 표시

Question

나는 간단한 bake 스크립트를 사용하여 구운 cakephp 2.x 응용 프로그램을 가지고 있습니다. 두 가지 주요 테이블은 조건과 약물입니다. 상태 HABTM 마약 및 부인장. 나는 조건 색인에있는 조건에 속하는 약품, 모든 조건을 기재하는 기본 약품을 표시하려하지만, 오직 그 약품 만 표시하려고합니다. 나는 또 다른 1.3 응용 프로그램에서 작동하는 쉼표로 분리 된 목록에서 조건에 속하는 약물 표시하려면 다음과 같이 그 일을 시도 :

<?php 
    $condition_drugs = ''; 
    foreach($condition['Drug'] as $drug): 
     $condition_drugs .= $drug['drug'] . ', '; 
     //echo $drug['generic']; 
    endforeach; 
    //echo substr($condition_drugs, 0, -2); 
    echo $condition_drugs; 
?> 

를하지만 다음과 같은 두 가지 오류가 있습니다 : 정의되지 않은 인덱스 : 약물 [ APP/View/Conditions/index.ctp, 22 행] 및 foreach() [APP/뷰/조건/index.ctp, 22 행]에 잘못된 인수가 제공됨을 알립니다. 그것은 비슷한 방식으로. 내가 가지고있는 코드에 문제가 있습니까? ID를 기반으로 내 모델에서 찾기가 필요합니까? 여기에 전체 인덱스 뷰 코드와 컨트롤러는 다음과 같습니다
