Using as Symfony Console Commands

Migrations come with predefined Symfony Console Commands. For integration to Nette DI use Kdyby/Console. Just register and configure MigrationsExtension in your config.neon:

    migrations: Nextras\Migrations\Bridges\NetteDI\MigrationsExtension

    dir: %appDir%/../migrations # migrations base directory
    driver: pgsql               # pgsql or mysql
    dbal: nextras               # nextras, nette, doctrine or dibi

Three basic commands are available:

  • Create new migrations with migrations:create command.
  • Run new migrations with migrations:continue command.
  • Drop database and run all migrations with migrations:reset command.

Dummy data

If you want the dummy-data folder to be executed as well, set the withDummyData value to TRUE in the extension's configuration. You typically want to set this in the local config of your development environment.

    withDummyData: TRUE

Low-level Usage

Create new PHP file (e.g. ./migrations/run.php) with the following content:

use Nextras\Migrations\Bridges;
use Nextras\Migrations\Controllers;
use Nextras\Migrations\Drivers;
use Nextras\Migrations\Extensions;

require __DIR__ . '/../vendor/autoload.php';

$conn = new Nextras\Dbal\Connection(...);
// or   new Nette\Database\Connection(...);
// or   new Doctrine\Dbal\Connection(...);
// or   new DibiConnection(...);

$dbal = new Bridges\NextrasDbal\NextrasAdapter($conn);
// or   new Bridges\NetteDatabase\NetteAdapter($conn);
// or   new Bridges\DoctrineDbal\DoctrineAdapter($conn);
// or   new Bridges\Dibi\DibiAdapter($conn);

$driver = new Drivers\PgSqlDriver($dbal);
// or     new Drivers\MySqlDriver($dbal);

$controller = new Controllers\HttpController($driver);
// or         new Controllers\ConsoleController($driver);

$baseDir = __DIR__;
$controller->addGroup('structures', "$baseDir/structures");
$controller->addGroup('basic-data', "$baseDir/basic-data", ['structures']);
$controller->addGroup('dummy-data', "$baseDir/dummy-data", ['basic-data']);
$controller->addExtension('sql', new Extensions\SqlHandler($driver));


Open the script in your browser (HttpController) or in a terminal (ConsoleController).

Organizing Migrations

The following structure is recommended and used by Symfony Console Commands by default:

├── basic-data                           # for both development and production
│   ├── 2015-03-16-170342-languages.sql  # YYYY-MM-DD-HHMMSS-label.extension
│   └── ...
├── dummy-data                           # for development on localhost
│   ├── 2015-03-17-104235-users.sql
│   └── ...
├── structures                           # create, alter tables...
│   ├── 2015-03-17-155419-users.sql
│   └── ...
└── run.php                              # start script if you don't
                                         # use Symfony Console Commands

Optionally you can use deep directory structure which is suitable if you have a lot of migrations:

├── basic-data/
│   └── 2015/
│       ├── 03/
│       │   ├── 2015-03-16-170342-languages.sql
│       │   └── ...
│       └── 04/
│           └── ...
└── ...

Extension Handlers


Most commonly used handler. Executes all SQL queries contained in a file.

// installation in migrations/run.php
$controller->addExtension('sql', new Extensions\SqlHandler($driver));


Used for complex migrations which can not be written in SQL.

// installation in migrations/run.php
$controller->addExtension('php', new Extensions\PhpHandler([
    // list of parameters passed to PHP script, e.g.
    'dibi' => $conn,
