MongoDB Migrations Bundle

This bundle integrates the MongoDB Migrations library into Symfony to get you set up more quickly.

It was moved to the doesntmattr organisation from antimattr/mongodb-migrations-bundle to continue maintenance (See issue 16).

The original authors are @rcatlin and @matthewfitz

PHP Version Support

If you require php 5.6 support use version ^1.0. Version ^3.0 requires at least php 7.1. The 1.x releases will only receive bug fixes.

Installation

Install with composer:

# For php 5.6
composer require "doesntmattr/mongodb-migrations-bundle=^1.0"

# For php 7.1
composer require "doesntmattr/mongodb-migrations-bundle=^3.0"

then enable the bundle in AppKernel.php by including the following:

// app/AppKernel.php
public function registerBundles()
{
    $bundles = [
        //...
        new AntiMattr\Bundle\MongoDBMigrationsBundle\MongoDBMigrationsBundle(),
    ];
}

Configuration

Add following configuration lines to config.yml file.

# app/config/config.yml
mongo_db_migrations:
    collection_name: "migration_versions"
    database_name: "opensky_devo"
    dir_name: "%kernel.project_dir%/src/OpenSky/Bundle/MainBundle/Migrations/MongoDB"
    script_dir_name: "%kernel.project_dir%/scripts"
    name: "OpenSky DEVO MongoDB Migrations"
    namespace: "OpenSky\\Bundle\\MainBundle\\MigrationsMongoDB"

Container Aware Migrations

In some cases you might want to access some services you have defined in the container. For example you may want to use a Factory to create new entities in the structure you need.

To get access to the container simply implement the ContainerAwareInterface including the required method setContainer():

// ...
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. If so, add the MongoDB option ['socketTimeoutMs' => -1] to your update method.

Features

For a full list of available features, see the README.md in the MongoDB Migrations library:

https://github.com/doesntmattr/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:

Generate a New Migration

> ./console mongodb:migrations:generate
Generated new migration class to "Example/Migrations/TestAntiMattr/MongoDB/Version20140822185742.php"

Status of Migrations

> ./console mongodb:migrations:status

Migrate all Migrations

This is what you will execute during your deployment process.

./console mongodb:migrations:migrate

Use --replay if you need to re-run an executed migration.

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
