when flush() primary key does not get inserted

I am working on a PHP Project, utilizing Symfony 2, and Doctrine as ORM. When I persist and flush the object the primary key column is not even in the insert SQL DML Statement, and of course an error is thrown. The ID is a generated value, using PHP's uniqid. I will provide the Entity and a code snippet of the controller.

/**
* Metrics
*
* @ORM\Table(name="metrics", indexes={@ORM\Index(name="metrics_assignedTo_fk",     columns={"assignedTo"}), @ORM\Index(name="metrics_ui_fk", columns={"ui"})})
* @ORM\Entity
*/
class Metrics
{
/**
 * @var string
 *
 * @ORM\Column(name="baseline", type="string", length=15, nullable=true)
 */
private $baseline;

/**
 * @var string
 *
 * @ORM\Column(name="testEvent", type="string", length=40, nullable=true)
 */
private $testevent;

/**
 * @var string
 *
 * @ORM\Column(name="status", type="string", length=20, nullable=true)
 */
private $status;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="date", type="date", nullable=true)
 */
private $date;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="shotStart", type="datetime", nullable=true)
 */
private $shotstart;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="shotEnd", type="datetime", nullable=true)
 */
private $shotend;

/**
 * @var string
 *
 * @ORM\Column(name="c2p", type="string", length=10, nullable=true)
 */
private $c2p;

/**
 * @var string
 *
 * @ORM\Column(name="notes", type="string", length=200, nullable=true)
 */
private $notes;

/**
 * @var string
 *
 * @ORM\Column(name="uniqueid", type="string", length=100, nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="NONE")
 */
private $uniqueid;

/**
 * @var \fti\webBundle\Entity\Employees
 *
 * @ORM\ManyToOne(targetEntity="fti\webBundle\Entity\Employees")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="ui", referencedColumnName="empid")
 * })
 */
private $ui;
}

I left out the getters and setters for clarity.

$shotObj->setShotstart(date_create($postData['start']));
                $shotObj->setShotend(date_create($postData['end']));
                $shotObj->setC2p($postData['c2p']);
                $shotObj->setUniqueid((uniqid('', true)));


            $shotForm = $this->createFormBuilder($shotObj)

                        return $er->createQueryBuilder('e')
                            ->where('e.active = 1')
                            ->orderBy('e.lastname', 'ASC');
                    }
                ,
                    'multiple' => false,
                    'expanded' => false,
                    'placeholder' => '-',
                ))
                ->add('ui', 'entity', array(

                ->add('SubmitAndAlert', 'submit')
                ->getForm();

    $shotForm->handleRequest($request);
    if($shotForm->isValid()) {
        $formData = $request->request->get('form');
        if ($formData['test']) {
            $shotObj->setTestevent($formData['test']);
        }
        $em->persist($shotObj);
        $em->flush();
    }

The error that returns is: An exception occurred while executing 'INSERT INTO metrics (baseline, testEvent, status, shotStart, shotEnd, c2p, notes, date, ui, assignedTo) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params ["foo", "foo", null, "2015-03-03 00:30:00", "2015-03-03 02:30:00", "foo", "test", null, 18, 21]:

As you see, the primary key (uniqueId) is not in the columns to be inserted, which leads me to believe its mapping Any help would be greatly appreciated

回答1:

You should play with the @ORM\GeneratedValue(strategy="NONE"), you can choose from: AUTO, SEQUENCE, TABLE, IDENTITY, UUID, CUSTOM and NONE.

I use AUTO - Tells Doctrine to pick the strategy that is preferred by the used database platform. The preferred strategies are IDENTITY for MySQL, SQLite and MsSQL and SEQUENCE for Oracle and PostgreSQL. This strategy provides full portability.

If you are using PHP uniqueid generation use the next anotation:

/**
 * @ORM\Column(type="guid")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="UUID")
 */

Thanks for all the help guys. The answer ended up being, in the orm.xml files for doctrine, the generatedvalue would never change, I manually removed the generatedvalue, in the xml document. After this, the insert DML statement worked correctly, and I see the row in my DB. The orm.xml file is in the Bundle/Resources/config/doctrine directory.
