Mysql 条令2@Gedmo\SoftDelete和unique字段

当我有唯一字段时，@Gedmo\SoftDeleteable有问题。 如果我从表中删除一些行并创建一个try-put新记录，并且通过使用该名称给出mi错误：

SQLSTATE[23000]：完整性约束冲突：密钥“UNIQ**************”的1062个重复条目“weqwewqe1”

如何在正确的位置将此消息更改为验证表单消息？

并且应该给我发送一个记录已经存在的消息表单

钢铁我还没有解决这个问题。我需要捕获此异常并发送到表单消息此名称已准备就绪。 请帮忙。

你知道“软删除”是什么意思吗？这意味着每个“删除”操作都将转换为SQL，只将一些

deleted

标记设置为

true

。若您将插入另一行，该行具有与已软删除行相同的唯一字段值，您将收到此消息

解决此问题有两种方法：

• 使用两列创建唯一索引：原始唯一字段和

  deleted

  标志。然后，只有当您尝试为“未软删除”添加具有现有唯一字段值的行时，才会出现此错误
• 避免发生这种冲突：您应该排除在唯一字段中添加与另一行重复的行的可能性

第二种方法是IMHO的最佳方法。

唯一约束！ 您必须使用

UniqueConstraints

，而不是

uniquentity

例如，对于

name

，在

name

和

deletedDate

之间创建一个

UniqueConstraint

use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;

/**
 * @ORM\Entity(repositoryClass="Eteam\PageBundle\Entity\Repository\PageRepository")
 * @ORM\Table(name="page",uniqueConstraints={@ORM\UniqueConstraint(name="name_unique", columns={"name", "deleted_date"})})
 * @Gedmo\SoftDeleteable(fieldName="deletedDate", timeAware=false)
 */
class Page
{
    //..
}

Mick的不错的解决方案：

/**
*@ORM\Table（name=“page”，uniqueConstraints={@ORM\UniqueConstraint（name=“name\u unique”，columns={“name”，“deleted\u date”}）
*/

可能适用于postgresql，但在mysql（）的某些版本中不起作用。 如何

发送到表单消息此名称已存在。

？ 例如，我们可以在控制器中更改操作newAction和editAction（当在控制台中创建CRUD时）：

编辑操作：

/**
 * Displays a form to edit an existing computer entity.
 *
 * @Route("/{id}/edit", name="computer_edit")
 * @Method({"GET", "POST"})
 */
public function editAction(Request $request, Computer $computer)
{
    $deleteForm = $this->createDeleteForm($computer);
    $editForm = $this->createForm('AppBundle\Form\ComputerType', $computer);
    $editForm->handleRequest($request);

    if ($editForm->isSubmitted() && $editForm->isValid()) {
        $warning = $this->uniqueInventoryNr($computer->getId(),$computer->getInventoryNr()); // added
        if ( $warning == '') { // added
            $this->getDoctrine()->getManager()->flush();

            return $this->redirectToRoute('computer_edit', array('id' => $computer->getId()));
        } else { // added
            $form_error = new \Symfony\Component\Form\FormError($warning); // added
            $editForm->addError($form_error); // added
        } // added
    }

    return $this->render('computer/edit.html.twig', array(
        'computer' => $computer,
        'edit_form' => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));
}

检查功能：

private function uniqueInventoryNr($computerId,$inventoryNr)
{
    $message = '';
    $em = $this->getDoctrine()->getManager();
    $computer_in = $em->getRepository('AppBundle\Entity\Computer')->findBy(array('inventoryNr' => $inventoryNr));
    if (count($computer_in) > 0) {
        if ($computer_in[0]->getId() != $computerId) // avoid when you edit
        { 
            $message =  'Inventory number is duplicated. '; 
        }
    }
    return $message;
}

---

好吧，一切都很好，但我仍然不知道如何在正确的位置显示异常，以给定名称的形式已经存在？

private function uniqueInventoryNr($computerId,$inventoryNr)
{
    $message = '';
    $em = $this->getDoctrine()->getManager();
    $computer_in = $em->getRepository('AppBundle\Entity\Computer')->findBy(array('inventoryNr' => $inventoryNr));
    if (count($computer_in) > 0) {
        if ($computer_in[0]->getId() != $computerId) // avoid when you edit
        { 
            $message =  'Inventory number is duplicated. '; 
        }
    }
    return $message;
}
