在迁移文件中使用 EntityManager

问题描述

限时删除！！

我有此代码但不起作用:

I have this code but does not work:

<?php

namespace ApplicationMigrations;

use DoctrineDBALMigrationsAbstractMigration,
    DoctrineDBALSchemaSchema;

/**
 * Auto-generated Migration: Please modify to your need!
 */
class Version20131021150555 extends AbstractMigration
{

    public function up(Schema $schema)
    {
        // this up() migration is auto-generated, please modify it to your needs
        $this->abortIf($this->connection->getDatabasePlatform()->getName() != "mysql", "Migration can only be executed safely on 'mysql'.");

        $this->addSql("ALTER TABLE person ADD tellphone LONGTEXT DEFAULT NULL");

        $em = $em = $this->getDoctrine()->getEntityManager();
        $persons = $em->getRepository('AutogestionBundle:Person')->fetchAll();

        foreach($persons as $person){
            $person->setTellPhone($person->getCellPhone());
            $em->persist($person);
        }
        $em->flush();
    }

    public function down(Schema $schema)
    {
        // this down() migration is auto-generated, please modify it to your needs
        $this->abortIf($this->connection->getDatabasePlatform()->getName() != "mysql", "Migration can only be executed safely on 'mysql'.");

        $this->addSql("ALTER TABLE person DROP tellphone");
    }
}

我在新的字段tellphone 中添加了手机中的信息.

I have add info in cellphone in a new field tellphone.

谢谢

推荐答案

这可能是一个较旧的帖子，但同时问题已经解决并且实际上是当前文档的一部分.

This may be an older post, but meanwhile the problem is solved and actually part of the current documentation.

参见 http://symfony.com/doc/current/bundles/DoctrineMigrationsBundle/index.html#container-aware-migrations

// ...
use SymfonyComponentDependencyInjectionContainerAwareInterface;
use SymfonyComponentDependencyInjectionContainerInterface;
use SymfonyComponentDependencyInjectionContainerAwareTrait;

class Version20130326212938 extends AbstractMigration implements ContainerAwareInterface
{
    use ContainerAwareTrait;

    public function up(Schema $schema)
    {
        // ... migration content
    }

    public function postUp(Schema $schema)
    {
        $em = $this->container->get('doctrine.orm.entity_manager');
        // ... update the entities
    }
}
