CakePHP 3.7。這是我的“用戶”表：<?phpnamespace App\Model\Table;use Cake\Datasource\EntityInterface;use Cake\ORM\Association\BelongsTo;use Cake\ORM\RulesChecker;use Cake\ORM\Table;use Cake\Validation\Validator;class UsersTable extends Table{    public function initialize(array $config)    {        parent::initialize($config);        $this->setTable('users');        $this->setDisplayField('id');        $this->setPrimaryKey('id');        $this->belongsTo('Customers', [            'foreignKey' => 'customer_id',            'joinType' => 'LEFT'        ]);    }    public function validationDefault(Validator $validator)    {        ...     }    public function buildRules(RulesChecker $rules)    {        $rules->add($rules->isUnique(['email']));        $rules->add($rules->existsIn(['customer_id'], 'Customers'));        return $rules;    }}和“客戶”表：<?phpnamespace App\Model\Table;use App\Model\Entity\Customer;use Cake\Datasource\EntityInterface;use Cake\ORM\Association\HasMany;use Cake\ORM\Table;use Cake\Validation\Validator;class CustomersTable extends Table{    public function initialize(array $config)    {        parent::initialize($config);        $this->setTable('customers');        $this->setDisplayField('company_name');        $this->setPrimaryKey('id');        $this->hasMany('Users', [            'foreignKey' => 'customer_id'        ]);    }    public function validationDefault(Validator $validator)    {        ...    }}好吧，現(xiàn)在我想通過 檢索控制器和模板中的關聯(lián)字段customer_id，例如：$this->Auth->user('customer_id')); // <--- WORKS$this->Auth->user('Customers.company_name')); // <--- ???我不明白必須使用什么語法通過外鍵 ( customer_id) “導航”才能讀取Customers表中的其他字段。當然，我可以使用一種解決方法：檢索“customer_id”值（如上）為該 ID 創(chuàng)建一個關于“客戶”過濾的查詢閱讀其他領域但我想這不是最好的方法。
