如何在查找时从关联模型中选择字段

Question

在我拥有这个之前：

//ArticlesController::index
$articles = $this->Articles->find('all', [
  'contain' => ['Comments']
]);

所以我设置 fields key:

//ArticlesController::index
$articles = $this->Articles->find('all', [
  'fields' => ['title', 'text],
  'contain' => ['Comments']
]);

由于我设置了 fields key，find 的结果不再带来 comments。

Answer 1

$articles = $this->Articles->find('all')
        ->select(['fields_you_want_from_Articles'])
        ->contain(['Comments'  => function($q) {
            return $q
                ->select(['fields_you_want_from_Comments']);
        }]);
