README
Simple Migrations for Zend Framework 2. Project originally based on ZendDbMigrations but module author did not response for issues and pull-requests so fork became independent project.
Supported Drivers
The following DB adapter drivers are supported by this module.
- Pdo_Sqlite
- Pdo_Mysql
- Mysqli only if you configure the driver options with
'buffer_results' => true
Installation
Using composer
php composer.phar require vgarvardt/zf-simple-migrations:dev-master php composer.phar update
add ZfSimpleMigrations
to the modules
array in application.config.php
Usage
Available commands
migration version [<name>]
- show last applied migration (name
specifies a configured migration)migration list [<name>] [--all]
- list available migrations (all
includes applied migrations)migration apply [<name>] [<version>] [--force] [--down] [--fake]
- apply or rollback migrationmigration generate [<name>]
- generate migration skeleton class
Migration classes are stored in /path/to/project/migrations/
dir by default.
Generic migration class has name Version<YmdHis>
and implement ZfSimpleMigrations\Library\MigrationInterface
.
Migration class example
<?php namespace ZfSimpleMigrations\Migrations; use ZfSimpleMigrations\Library\AbstractMigration; use Zend\Db\Metadata\MetadataInterface; class Version20130403165433 extends AbstractMigration { public static $description = "Migration description"; public function up(MetadataInterface $schema) { //$this->addSql(/*Sql instruction*/); } public function down(MetadataInterface $schema) { //$this->addSql(/*Sql instruction*/); } }
Multi-statement sql
While this module supports execution of multiple SQL statements it does not have way to detect if any other statement than the first contained an error. It is highly recommended you only provide single SQL statements to addSql
at a time.
I.e instead of
$this->addSql('SELECT NOW(); SELECT NOW(); SELECT NOW();');
You should use
$this->addSql('SELECT NOW();');
$this->addSql('SELECT NOW();');
$this->addSql('SELECT NOW();');
Accessing ServiceLocator In Migration Class
By implementing the Zend\ServiceManager\ServiceLocatorAwareInterface
in your migration class you get access to the
ServiceLocator used in the application.
<?php namespace ZfSimpleMigrations\Migrations; use ZfSimpleMigrations\Library\AbstractMigration; use Zend\Db\Metadata\MetadataInterface; use Zend\ServiceManager\ServiceLocatorAwareInterface; use Zend\ServiceManager\ServiceLocatorAwareTrait; class Version20130403165433 extends AbstractMigration implements ServiceLocatorAwareInterface { use ServiceLocatorAwareTrait; public static $description = "Migration description"; public function up(MetadataInterface $schema) { //$this->getServiceLocator()->get(/*Get service by alias*/); //$this->addSql(/*Sql instruction*/); } public function down(MetadataInterface $schema) { //$this->getServiceLocator()->get(/*Get service by alias*/); //$this->addSql(/*Sql instruction*/); } }
Accessing Zend Db Adapter In Migration Class
By implementing the Zend\Db\Adapter\AdapterAwareInterface
in your migration class you get access to the
Db Adapter configured for the migration.
<?php namespace ZfSimpleMigrations\Migrations; use Zend\Db\Adapter\AdapterAwareInterface; use Zend\Db\Adapter\AdapterAwareTrait; use Zend\Db\Sql\Ddl\Column\Integer; use Zend\Db\Sql\Ddl\Column\Varchar; use Zend\Db\Sql\Ddl\Constraint\PrimaryKey; use Zend\Db\Sql\Ddl\CreateTable; use Zend\Db\Sql\Ddl\DropTable; use ZfSimpleMigrations\Library\AbstractMigration; use Zend\Db\Metadata\MetadataInterface; class Version20150524162247 extends AbstractMigration implements AdapterAwareInterface { use AdapterAwareTrait; public static $description = "Migration description"; public function up(MetadataInterface $schema) { $table = new CreateTable('my_table'); $table->addColumn(new Integer('id', false)); $table->addConstraint(new PrimaryKey('id')); $table->addColumn(new Varchar('my_column', 64)); $this->addSql($table->getSqlString($this->adapter->getPlatform())); } public function down(MetadataInterface $schema) { $drop = new DropTable('my_table'); $this->addSql($drop->getSqlString($this->adapter->getPlatform())); } }
Configuration
User Configuration
The top-level key used to configure this module is migrations
.
Migration Configurations: Migrations Name
Each key under migrations
is a migrations configuration, and the value is an array with one or more of
the following keys.
Sub-key: dir
The path to the directory where migration files are stored. Defaults to ./migrations
in the project root dir.
Sub-key: namespace
The class namespace that migration classes will be generated with. Defaults to ZfSimpleMigrations\Migrations
.
Sub-key: show_log
(optional)
Flag to log output of the migration. Defaults to true
.
Sub-key: adapter
(optional)
The service alias that will be used to fetch a Zend\Db\Adapter\Adapter
from the service manager.
User configuration example:
'migrations' => array( 'default' => array( 'dir' => dirname(__FILE__) . '/../../../../migrations-app', 'namespace' => 'App\Migrations', ), 'albums' => array( 'dir' => dirname(__FILE__) . '/../../../../migrations-albums', 'namespace' => 'Albums\Migrations', 'adapter' => 'AlbumDb' ), ),
