推荐答案
包含绝对是用于过滤相关记录的方法。确保在模型或app_model中添加$ actsAs = array('Containable')。
Containable is definitely the way to go for filtering related records. Make sure to add $actsAs = array('Containable') into your model or app_model.
然后您可以执行以下操作:
Then you can do things like:
$this->Product->find('all', array(
'contain' => array(
'Artist' => array(
'Person' => array(
'id',
'first_name'
)
)
)
));
