README
This bundle integrates the AntiMattr MongoDB Migrations library. into Symfony so that you can safely and quickly manage MongoDB migrations.
Installation
Add the following to your composer.json file:
{ "require": { "antimattr/mongodb-migrations": "~1.0@stable", "antimattr/mongodb-migrations-bundle": "~1.0@stable" } }
Install the libraries by running:
composer install
If everything worked, the MonogDBMigrationsBundle can now be found at vendor/antimattr/mongodb-migrations-bundle.
Finally, be sure to enable the bundle in AppKernel.php by including the following:
// app/AppKernel.php public function registerBundles() { $bundles = array( //... new AntiMattr\Bundle\MongoDBMigrationsBundle\MongoDBMigrationsBundle(), ); }
Configuration
mongo_db_migrations: collection_name: "migration_versions" database_name: "opensky_devo" dir_name: "%kernel.root_dir%/../src/OpenSky/Bundle/MainBundle/Migrations/MongoDB" script_dir_name: "%kernel.root_dir%/scripts" name: "OpenSky DEVO MongoDB Migrations" namespace: "OpenSky\Bundle\MainBundle\Migrations\MongoDB"
Container Aware Migrations
In some cases you might need access to the container to ensure the proper update of your data structure. This could be necessary to update relations with some specific logic or to create new entities.
Therefore you can just implement the ContainerAwareInterface with its needed methods to get full access to the container.
// ... use Symfony\Component\DependencyInjection\ContainerAwareInterface; use Symfony\Component\DependencyInjection\ContainerInterface; class Version20130326212938 extends AbstractMigration implements ContainerAwareInterface { private $container; public function setContainer(ContainerInterface $container = null) { $this->container = $container; } public function up(Database $db) { // ... migration content } public function postUp(Database $db) { $dm = $this->container->get('doctrine.odm.default_document_manager'); // ... update the entities } }
MongoDB Cursor Timeouts
In some cases you may need the Cursor timeout to be extended. You can of course do this on a per migration basis, or you can do this for all migrations by extending the base migration and adding to the constructor.
// ... use AntiMattr\MongoDB\Migrations\AbstractMigration as BaseMigration; use AntiMattr\MongoDB\Migrations\Version; use MongoCursor; abstract class AbstractMigration extends BaseMigration { /** * @var AntiMattr\MongoDB\Migrations\Version */ public function __construct(Version $version) { parent::__construct($version); MongoCursor::$timeout = -1; } }
Features
For a full list of available features, see the README.md in the underlying library
https://github.com/antimattr/mongodb-migrations/blob/master/README.md
Differences from the underlying library are limited to the Console commands, namely database configurations are handled by Symfony's Dependency injection container, so you don't pass them as command line args.
Examples of the Command Line args with the difference below:
Features - Generate a New Migration
> ./console mongodb:migrations:generate Generated new migration class to "Example/Migrations/TestAntiMattr/MongoDB/Version20140822185742.php"
Features - Status of Migrations
> ./console mongodb:migrations:status == Configuration >> Name: AntiMattr Example Migrations >> Database Driver: MongoDB >> Database Name: test_antimattr_migrations >> Configuration Source: demo/ConsoleApplication/config/test_antimattr_mongodb.yml >> Version Collection Name: migration_versions >> Migrations Namespace: Example\Migrations\TestAntiMattr\MongoDB >> Migrations Directory: Example/Migrations/TestAntiMattr/MongoDB >> Current Version: 0 >> Latest Version: 2014-08-22 18:57:44 (20140822185744) >> Executed Migrations: 0 >> Executed Unavailable Migrations: 0 >> Available Migrations: 3 >> New Migrations: 3
Features - Migrate all Migrations
This is what you will execute during your deployment process.

Features - Version Up or Down
Is your migration history out of sync for some reason? You can manually add or remove a record from the history without running the underlying migration.
You can delete
./console mongodb:migrations:version --delete 20140822185744
You can add
./console mongodb:migrations:version --add 20140822185744
