Custom Integration

For up to date code take a look at the doctrine migrations command line integration. None the less the main steps required to make a functional integration are presented below.

Installation

First you need to require Doctrine Migrations as a dependency of your code

composer require doctrine/migrations

Then you have to require the composer autoloader to use the classes from the `Doctrine\DBAL\Migrations` namespace in your project:

$autoloadFiles = array(
    __DIR__ . '/../vendor/autoload.php',
    __DIR__ . '/../../../autoload.php'
);

$autoloader = false;
foreach ($autoloadFiles as $autoloadFile) {
    if (file_exists($autoloadFile)) {
        require_once $autoloadFile;
        $autoloader = true;
    }
}

if (!$autoloader) {
    die('vendor/autoload.php could not be found. Did you run `php composer.phar install`?');
}

Now the above autoloader is able to load a class like the following:

/path/to/migrations/lib/Doctrine/DBAL/Migrations/Migrations/Migration.php

Register Console Commands

Now that we have setup the autoloaders we are ready to add the migration console commands to our Doctrine Command Line Interface:

// ...

$cli->addCommands(array(
    // Migrations Commands
    new \Doctrine\DBAL\Migrations\Tools\Console\Command\ExecuteCommand(),
    new \Doctrine\DBAL\Migrations\Tools\Console\Command\GenerateCommand(),
    new \Doctrine\DBAL\Migrations\Tools\Console\Command\LatestCommand(),
    new \Doctrine\DBAL\Migrations\Tools\Console\Command\MigrateCommand(),
    new \Doctrine\DBAL\Migrations\Tools\Console\Command\StatusCommand(),
    new \Doctrine\DBAL\Migrations\Tools\Console\Command\VersionCommand()
));

Register Console helpers

Additionally you have to make sure the 'db' and 'dialog' Helpers are added to your Symfony Console HelperSet in a cli-config.php file.

This file can be either in the directory you are calling the console tool from or in as config subfolder.

$db = \Doctrine\DBAL\DriverManager::getConnection($params);
// or
$em = \Doctrine\ORM\EntityManager::create($params);
$db = $em->getConnection();

$helperSet = new \Symfony\Component\Console\Helper\HelperSet(array(
    'db' => new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($db),
    'question' => new \Symfony\Component\Console\Helper\QuestionHelper(),
));

return $helperset;

Note that the db helper is not required as you might want to pass the connection information from the command line directly.

You will see that you have a few new commands when you execute the following command:

$ ./doctrine list migrations
Doctrine Command Line Interface version 1.2.1

Usage:
  [options] command [arguments]

Options:
  --help           -h Display this help message.
  --quiet          -q Do not output any message.
  --verbose        -v Increase verbosity of messages.
  --version        -V Display this program version.
  --color          -c Force ANSI color output.
  --no-interaction -n Do not ask any interactive question.

Available commands for the "migrations" namespace:
  :diff      Generate a migration by comparing your current database to your mapping information.
  :execute   Execute a single migration version up or down manually.
  :generate  Generate a blank migration class.
  :migrate   Execute a migration to a specified version or the latest available version.
  :status    View the status of a set of migrations.
  :version   Manually add and delete migration versions from the version table.
