orm - 在 CakePHP 3 Controller 中保存相关数据

Question

在文档中确切地说关联数据可以像这样保存:

use App\Model\Entity\Article;
use App\Model\Entity\User;

$article = new Article(['title' => 'First post']);
$article->user = new User(['id' => 1, 'username' => 'mark']);

$articles = TableRegistry::get('Articles');
$articles->save($article);

我在我的代码中试过这个但是我得到错误:

fatal error 错误:找不到类“App\Controller\TableRegistry”
文件/Users/mtkocak/Sites/gscrm/src/Controller/BusinessesController.php行:62

这是我的 Controller 代码。我怀疑上面的代码对实体模型是否有效。

    public function add() {
    $business = $this->Businesses->newEntity($this->request->data);
    $record = new Record($this->request->data['Records']);

    $address = new Address($this->request->data['Addresses']);
    $telephone = new Telephone($this->request->data['Telephones']);
    $email = new Email($this->request->data['Emails']);

    $record->business = $business;
    $record->address = $address;
    $record->email = $email;

    if ($this->request->is('post')) {
        var_dump($this->request->data['Records']);
        $records = TableRegistry::get('Records');
        $records->save($record);
        // if ($this->Businesses->save($business)) {
        //     $this->Flash->success('The business has been saved.');
        //     return $this->redirect(['action' => 'index']);
        // } else {
        //     $this->Flash->error('The business could not be saved. Please, try again.');
        // }
    }
    $telephonetypes = $this->Businesses->Records->Telephones->Telephonetypes->find('list');
    $records = $this->Businesses->Records->find('list');
    $businesstypes = $this->Businesses->Businesstypes->find('list');
    $this->set(compact('telephonetypes','business', 'records', 'businesstypes'));
}

这是我的表的 sql 转储:

    CREATE TABLE IF NOT EXISTS `businesses` (
    `id` int(10) unsigned NOT NULL,
  `record_id` int(10) unsigned DEFAULT NULL,
  `businesstype_id` int(10) unsigned DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_turkish_ci AUTO_INCREMENT=1 ;

ALTER TABLE `businesses`
 ADD PRIMARY KEY (`id`), ADD KEY `FK_businesses_records` (`record_id`), ADD KEY `FK_businesses_businesstypes` (`businesstype_id`);

感谢任何帮助。

您缺少 use 语句。本书中的所有这些示例理所当然地认为您已经从头开始阅读表格部分并利用:

use Cake\ORM\TableRegistry;

附言。遵循命名约定时，您不必手动构建实体
