CakePHP 2.6.7 hasMany 数据未保存

CakePHP是一个流行的PHP开发框架，其版本2.6.7中存在一个问题，即在使用hasMany关联关系时，数据未能正确保存的问题。本文将介绍这个问题，并提供解决方案。

php
class Author extends AppModel {
    public $hasMany = array(
        'Article' => array(
            'className' => 'Article',
            'foreignKey' => 'author_id'
        )
    );
}

php
class AuthorsController extends AppController {
    public function add() {
        if ($this->request->is('post')) {
            $this->Author->create();
            if ($this->Author->save($this->request->data)) {
                $this->Session->setFlash('Author saved successfully.');
                $this->redirect(array('action' => 'index'));
            } else {
                $this->Session->setFlash('Unable to save author.');
            }
        }
    }
}

php
class AuthorsController extends AppController {
    public function add() {
        if ($this->request->is('post')) {
            $this->Author->create();
            $this->Author->begin(); // 开始事务
            if ($this->Author->saveAssociated($this->request->data)) {
                $this->Author->commit(); // 提交事务
                $this->Session->setFlash('Author saved successfully.');
                $this->redirect(array('action' => 'index'));
            } else {
                $this->Author->rollback(); // 回滚事务
                $this->Session->setFlash('Unable to save author.');
            }
        }
    }
}
