Question

我有这个错误：

无法插入行，缺少部分主键值。拿到（， 16,19），期待（id，passenger_id，invoices_id

现在我无法插入字段，因为不要生成ID，在我的表格中我将其视为自动增量。

public function printInvoice($id = null)
{
  $this->layout = 'invoice';
  $this->loadModel('Travels');
  $invoices = $this->Tickets->getInvioce();
  if(!($this->Tickets->existPassengerTicket($id))){
    $ticket = $this->Tickets->newEntity();
    $ticket->passenger_id = $id;
    $ticket->invoices_id = $invoices->id;
    $ticket->date = date('Y-m-d H:i:s');
    $ticket = $this->Tickets->patchEntity($ticket, $this->request->data);
    $this->Tickets->save($ticket);
  }else{

  }
  //$passengers = $this->Tickets->getPassenger($id);
  //$invoices = $this->Tickets->getInvioce();
  //$idTravel=$passengers->travel_id;
  //$travels = $this->Travels->getTravel($idTravel);
  //$this->set(compact('ticket', 'passengers', 'invoices', 'travels'));
  //$this->set('_serialize', ['ticket']);
}

这里是SHOW CREATE TABLE门票：

| tickets | CREATE TABLE `tickets` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `passenger_id` int(11) NOT NULL,
  `invoice_id` int(11) NOT NULL,
  `date` datetime DEFAULT NULL,
  `update` datetime DEFAULT NULL,
  PRIMARY KEY (`id`,`passenger_id`,`invoice_id`),
  KEY `fk_tickets_passengers1_idx` (`passenger_id`),
  KEY `fk_tickets_invoices1_idx` (`invoice_id`),
  CONSTRAINT `fk_tickets_invoices1` FOREIGN KEY (`invoice_id`) REFERENCES `invoices` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION,
  CONSTRAINT `fk_tickets_passengers1` FOREIGN KEY (`passenger_id`) REFERENCES `passengers` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8 |

Answer 1

我认为你应该检查In Model / Entity / Tickets.php。当id，passenger_id，false时我得到了这个错误，我将其改为true就可以了。

protected $_accessible = [
        '*' => true,
        'id'=> false,
        'passenger_id' => false,
        'invoices_id' => false,
    ];

我认为当你将false改为true时你会好的。

protected $_accessible = [
        '*' => true,
        'id'=> true,
        'passenger_id' => true,
        'invoices_id' => true,
    ];

Answer 2

检查您的表类并查看validationDefault函数。

    $validator
        ->add('id', 'valid', ['rule' => 'numeric'])
        ->allowEmpty('id', 'create')
        // your other code here
    return $validator;

确保至少有两行代码引用了id的创建。我也会检查Entity对象，以防万一。

Answer 3

“无法插入行，缺少部分主键值。得到（1，），期待（id，something_id）”

通过编辑 ExampleTable.php ：

解决了这个错误

此代码导致错误：

$this->primaryKey(['id', 'something_id']);

这就是它的工作原理：

$this->primaryKey('id');

我使用mysql workbench创建了数据库，然后进行了蛋糕烘焙。所以，如果你喜欢我，我上面显示的解决方法也可能对你有用。

插入字段cakephp3时，它不会自动生成ID
