Migration module for MarekSkopalORM library.

Creates migrations from your Entity and database schema with simple API. Migrations are PHP files and that extends Migration class and may contain any of your custom logic.

Installation

Install via Composer:

composer require marekskopal/orm-migrations

Usage

Create Migrator instance

//Create DB connection
$database = new MysqlDatabase('localhost', 'root', 'password', 'database');

//Create schema
$schema = new SchemaBuilder()
    ->addEntityPath(__DIR__ . '/Entity')
    ->build();

//Create Migrator
$pathWithMigrations = __DIR__ . '/migrations/';
$migrator = new Migrator($pathWithMigrations, $database);

Create new migration

$migrator->generate(
    $schema,
    name: 'CreateUserTable',
);

This will create new migration PHP file in __DIR__ . '/migrations/' directory.

Example of generated migration file:

<?php

declare(strict_types=1);

namespace MarekSkopal\ORM\Migrations\Tests\Generator\Migrations;

use MarekSkopal\ORM\Enum\Type;
use MarekSkopal\ORM\Migrations\Migration\Migration;

final class CreateUserTable extends Migration
{
    public function up(): void
    {
        $this->table('table_a')
            ->addColumn('id', Type::Int, autoincrement: true, primary: true)
            ->addColumn('name', Type::String, nullable: true, size: 255)
            ->addColumn('address', Type::String, size: 50, default: 'New York')
            ->addColumn('score', Type::Int, size: 10)
            ->addColumn('price', Type::Decimal, precision: 10, scale: 2)
            ->addColumn('type', Type::Enum, enum: ['a', 'b', 'c'], default: 'a')
            ->create();
    }

    public function down(): void
    {
        $this->table('table_a')
            ->drop();
    }
}

Added, changed or removed tables, columns, indexes and keys are automatically detected from comparing Entity schema with your database.

Run migrations
