Symfony2，Doctrine，@UniqueEntity 处理异常 [英] Symfony2, Doctrine, @UniqueEntity handle exception

问题描述

实体

use DoctrineORMMapping as ORM;
use SymfonyComponentValidatorConstraints as Assert;
use SymfonyBridgeDoctrineValidatorConstraintsUniqueEntity;

/**
 * @ORMTable(name="_apiKey")
 * @ORMEntity(repositoryClass="EveProfileBundleEntityRepositoryapiKeyRepository")
 * @UniqueEntity(fields={"keyID", "vCode", "accountID"}, 
 * message="you already own this api")
 */
class apiKey
{

public function __construct()
{
    // empty
}

// relations start
// relations end

/**
 * @ORMColumn(name="entryID", type="integer")
 * @ORMId
 * @ORMGeneratedValue(strategy="AUTO")
 */
private $entryID;

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

/**
 * @ORMColumn(name="keyID", type="integer", nullable=false, unique=true)
 * @AssertNotBlank(message="keyID cannot be blank")
 */
private $keyID;

/**
 * @ORMColumn(name="vCode", type="string", nullable=false, unique=true)
 * @AssertNotBlank(message="vCode cannot be blank")
 */
private $vCode;

在数据库中

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 ;

当我尝试添加重复时出现错误

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' 

这很好，但我该如何处理呢?消息选项"在 @UniqueEntity() 中不起作用我如何在表单错误中显示此错误(无异常)

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(没有 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

key 'accountID'

如果您想单独检查 accountId 的唯一性，请将其添加到您的类中:

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

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

这里是检查组合keyID"、vCode"、accountID"的唯一性以及单独accountID"的唯一性的完整代码:

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

<?php

// ...

/**
 * @ORMTable(name="_apiKey")
 * @ORMEntity(repositoryClass="EveProfileBundleEntityRepositoryapiKeyRepository")
 * @UniqueEntity(fields={"keyID", "vCode", "accountID"}, message="you already own this api")
 * @UniqueEntity(fields={"accountID"}, message="This account ID is already taken")
 */
class apiKey
{

我不知道您是否看到该错误仅影响字段 accountID，如果您不希望出现这种行为，只需从您的属性 $accountID 中删除unique=true"即可.

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，可以这样操作:

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

/**
 * @ORMTable(name="_apiKey",
 *      uniqueConstraints = {
 *          @ORMUniqueConstraint(name="_api_key_key_id_v_code_account_id", columns={"keyID", "vCode", "accountID})
 *      }
 * )
 *
 * ...
 * etc, ...
 */
class apiKey
