The Development Requires
by Carles Climent
Provides an initial scaffolding for building migrations
Provides a little scaffolding for migrations., (*2)
1.- Add the bundle to your composer.json file and execute composer update
., (*3)
{ "require": { "aureka/migrate-bundle": "*" } }
2.- Modify your AppKernel.php
, (*4)
class AppKernel extends Kernel { public function registerBundles() { $bundles = array( // ... new Aureka\MigrateBundle\AurekaMigrateBundle(), ); // ... } }
3.- Configure your legacy database in config.yml
, (*5)
aureka_migrate: database: connector: 'mysqli' host: 'localhost' user: 'root' password: '123' database: 'my_database', (*6)
It is time for you to add your custom migrators. Declare each migrator as a service tagged by aureka_migrate.migrator
., (*7)
services: your_migration_bundle.users_migrator: class: Your\MigrationBundle\Migrator\UsersMigrator arguments: ['@aureka_migrate.legacy_connection', '@doctrine.orm.entity_manager'] tags: - { name: aureka_migrate.migrator }
A migrator could be something like this:, (*8)
use Doctrine\Common\Persistence\ObjectManager; use Aureka\MigrateBundle\Migrator\Migrator, Aureka\MigrateBundle\Service\Database\Connection; class UsersMigrator implements Migrator { private $legacyConnection; private $om; public function __construct(Connection $legacyConnection, ObjectManager $om) { $this->legacyConnection = $legacyConnection; $this->om = $om; } public function prepare() { // Do whatever you need to prepare the migration, like cleaning the destination tables return $this; } public function migrate() { $users = $this->legacyConnection->fetchAll('SELECT * FROM users'); foreach ($users as $legacy_user) { $user = new User; $user->name = $legacy_user['username']; // ... $this->om->persist($user); } $this->om->flush(); return $this; }
Now you can execute the following command:, (*9)
php app/console aureka_migrate:migrate
