Symfony2，Doctrine，@UniqueEntity句柄异常

问题描述

ENTITY

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

/**
 * @ORM\Table(name="_apiKey")
 * @ORM\Entity(repositoryClass="Eve\ProfileBundle\Entity\Repository\apiKeyRepository")
 * @UniqueEntity(fields={"keyID", "vCode", "accountID"},
 * message="you already own this api")
 */
class apiKey
{

public function __construct()
{
    // empty
}

// relations start
// relations end

/**
 * @ORM\Column(name="entryID", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $entryID;

/**
 * @ORM\Column(name="accountID", type="integer", nullable=false, unique=true)
 */
private $accountID;

/**
 * @ORM\Column(name="keyID", type="integer", nullable=false, unique=true)
 * @Assert\NotBlank(message="keyID cannot be blank")
 */
private $keyID;

/**
 * @ORM\Column(name="vCode", type="string", nullable=false, unique=true)
 * @Assert\NotBlank(message="vCode cannot be blank")
 */
private $vCode;

在db

CREATE TABLE IF NOT EXISTS `_apiKey` (
  `entryID` int(11) NOT NULL AUTO_INCREMENT,
  `accountID` int(11) NOT NULL,
  `keyID` int(11) NOT NULL,
  `vCode` varchar(255) NOT NULL,
  PRIMARY KEY (`entryID`),
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=18 ;

当我尝试添加dublicate我有错误

When i try to add dublicate i have an error

An exception occurred while executing 'INSERT INTO _apiKey (accountID, keyID, vCode) VALUES (?, ?, ?)' with params {"1":38,"2":"1233","3":"123"}:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '38-1233-123' for key 'accountID'

没关系，但我该怎么处理？ 消息选项在 @UniqueEntity（）中不起作用，如何在表单错误中显示此错误（无一例外）

and it's fine, but how can i handle it? "message option" is not working in @UniqueEntity() how can i show this error in form errors (without exception)

我想要什么（不含entryID的db的简单示例）

what i want (simple example for db without entryID)

123 123 123 - add
123 123 1234 - add
123 125 123 - add
123 123 1234 - form-error on inserting
123 123 123 - form-error on inserting
234 123 123 - add
234 123 123 - form-error on inserting

推荐答案

如果要检查唯一性的accountId单独添加到您的课堂：

If you want to check the uniqueness of accountId alone, add this to your class:

@UniqueEntity(fields={"accountID"}, message="This account is already taken")

这里是完整的代码，检查组合keyID， vCode，accountID，还有accountID的唯一性：

Here the full code that check the uniqueness of the combinaison "keyID", "vCode", "accountID" and also the uniqueness of "accountID" alone:

<?php

// ...

/**
 * @ORM\Table(name="_apiKey")
 * @ORM\Entity(repositoryClass="Eve\ProfileBundle\Entity\Repository\apiKeyRepository")
 * @UniqueEntity(fields={"keyID", "vCode", "accountID"}, message="you already own this api")
 * @UniqueEntity(fields={"accountID"}, message="This account ID is already taken")
 */
class apiKey
{

我不知道你是否看到错误只影响域accountID，如果你不希望这个行为只是从你的属性$ accountID中删除unique = true。

I don't know if you saw that the error only affect the field accountID, if you don't want this behavior just remove "unique=true" from your property $accountID.

如果你只想说cominaisonkeyID，vCode，accountID在数据库中必须是唯一的，请像下面那样执行：

If you just want to say that the cominaison "keyID", "vCode", "accountID" must be unique in the database, proceed like that:

/**
 * @ORM\Table(name="_apiKey",
 *      uniqueConstraints = {
 *          @ORM\UniqueConstraint(name="_api_key_key_id_v_code_account_id", columns={"keyID", "vCode", "accountID})
 *      }
 * )
 *
 * ...
 * etc, ...
 */
class apiKey
