有没有办法在没有主键的表中保存值？在cakephp 3中

class YourModelTable extends Table
{
    public function initialize(array $config)
    {
        parent::initialize($config);
        $this->setPrimaryKey(false);
    }
}

$entity = $this->YourModel->newEntity();
$entity->column1 = 'Value 1';
$entity->column2 = 'Value 2';

$this->YourModel->save($entity);
