Question

CakePHP 3.7.7。这是我的用户表：

CREATE TABLE users (
 id int(11) NOT NULL AUTO_INCREMENT,
 user_level_id int(11) NOT NULL,
 email varchar(255) NOT NULL,
 password varchar(255) NOT NULL,
 PRIMARY KEY (id),
 UNIQUE KEY email (email),
 KEY user_level_id (user_level_id),
 CONSTRAINT users_ibfk_1 FOREIGN KEY (user_level_id) REFERENCES user_levels (id) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

和用户级别：

CREATE TABLE user_levels (
 id int(11) NOT NULL AUTO_INCREMENT,
 level varchar(255) DEFAULT NULL,
 PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

在我看来，我可以通过外键通过以下方式访问level值：

<td><?= $user->has('user_level') ? $this->Html->link($user->user_level->level, ['controller' => 'UserLevels', 'action' => 'view', $user->user_level->id]) : '' ?></td>

我需要做同样的事情（在sidebar-menu.ctp, that as no controller associated) with the current logged user retrieved by $ Auth-> user（）`中。在这种情况下，我不明白什么是正确的语法：

$Auth->user()['user_level']

导致：

未定义索引：user_level

但是：

$Auth->user()['user_level_id']

有效，即使这不是我想要的。

这是我在AppController.php中定义$Auth的方式：

公共函数initialize（） { parent :: initialize（）;

    $this->loadComponent('RequestHandler', [
        'enableBeforeRedirect' => false,
    ]);
    $this->loadComponent('Flash', ['clear' => true]);
    $this->loadComponent('Auth', [
        'authenticate' => [
            'Form' => [
                'fields' => [
                    'username' => 'email',
                    'password' => 'password'
                ]
            ]
        ],
        'loginAction' => [
            'controller' => 'Users',
            'action' => 'login'
        ],
        'unauthorizedRedirect' => $this->referer()
    ]);
}

public function beforeRender(Event $event)
{
    $this->viewBuilder()->setTheme('AdminLTE');
    $this->viewBuilder()->setClassName('AdminLTE.AdminLTE');
    $this->set('Auth', $this->Auth);
}

public function isAuthorized($user = null)
{
    return false;
}

以及在UsersController.php中：

public function initialize()
{
    parent::initialize();
    $this->Auth->allow(['login']);
}

public function login()
{
    if ($this->request->is('post')) {
        $user = $this->Auth->identify();
        if ($user) {
            $this->Auth->setUser($user);
            return $this->redirect($this->Auth->redirectUrl());
        }
        $this->Flash->error(__('Username or password is incorrect.'));
    }
}

默认情况下，Auth组件仅从单个模型中获取数据，在这种情况下为用户。

如果要通过关系在Auth会话中存储数据，请在UsersTable中使用自定义查找器。

身份验证设置示例：

'authenticate' => [
                'Form' => [
                    'finder' => 'emailOrNameAuth',
                    'fields' => ['username' => 'name', 'password' => 'password']
                ]
            ],

UsersTable：

public function findEmailOrNameAuth(\Cake\ORM\Query $query, array $options)
{
    $query
        ->where(
            [
                'OR' => [
                'email' => $options['username'],
                'name' => $options['username']
                ],
                'activated' => 1,
            ]
        )
        ->contain(['UserLevels']); // <---- 

    return $query;
}
