Cakephp查询关联表的方法总结

SELECT * FROM Users AS User
LEFT JOIN Notes AS Note ON User.id = Note.user_id
WHERE
User.id = {$user_id}
AND
Note.subject LIKE '%{keyword}%'

$data = $this->User->query($sql);

//重新绑定关联指定查询条件
 
$this->User->unbindModel('Note');
$this->User->bindModel(
    'hasMany' => array(
        'Note' => array(
            'conditions' => array(
                'Note.subject LIKE' => '%'.$keyword.'%'
            )
        )
    )
);
 
//指定主表条件获取数据
$data = $this->User->find('all',array(
    'conditions' => array(
        'User.id' => $user_id
    )
));
 
//或者
 
$data = $this->User->read(null,$user_id);

class AppModel extends Model {
 
    //加载核心行为
    var $actsAs = array('Containable');
 
}

$this->User->contain('Note.subject LIKE' => '%'.$keyword.'%');
 
$data = $this->User->find('all',array(
    'conditions' => array(
        'User.id' => $user_id
    )
));

$data = $this->User->find('all',array(
    'conditions' => array(
        'User.id' => $user_id
    ),
    'contain' => array(
        'Note' => array(
            'conditions' => array(
                'Note.subject LIKE' => '%'.$keyword.'%'
            )
        )
    )
));

SELECT *
FROM users AS User
LEFT JOIN notes AS Note ON User.id = Note.user_id
WHERE
User.name LIKE '%keyword%'
OR
Note.subject LIKE '%keyword%'
