README

This is a typical migration for yii2:

 public function safeUp()
 {
 $this->createTable('characteristics_units', [
 'id' => $this->primaryKey(),
 'name' => $this->string()->notNull(),
 'short_name' => $this->string()->notNull(),
 'created' => $this->dateTime()->notNull()->defaultExpression('now()'),
 'updated' => $this->dateTime(),
 ]);

 $this->createTable('characteristics', [
 'id' => $this->primaryKey(),
 'characteristics_unit_id' => $this->integer()->notNull(),
 'name' => $this->string()->notNull(),
 'created' => $this->dateTime()->notNull()->defaultExpression('now()'),
 'updated' => $this->dateTime(),
 ]);

 $this->addForeignKey('characteristics_unit_id_characteristics_fk', 'characteristics', 'characteristics_unit_id', 'characteristics_units', 'id');
 }

 public function safeDown()
 {
 $this->dropTable('characteristics');
 $this->dropTable('characteristics_units');
 }

Why write more? If you use execut yii2-migration helper, you can write it faster and more compact:

 public function initInverter(\execut\yii\migration\Inverter $i)
 {
 $i->table('characteristics')->create(array_merge($this->defaultColumns(), [
 'name' => $this->string()->notNull(),
 'short_name' => $this->string()->notNull(),
 ]));

 $i->table('characteristics_units')->create(array_merge($this->defaultColumns(), [
 'name' => $this->string()->notNull(),
 ]))->addForeignColumn('characteristics');
 }

Installation

The preferred way to install this extension is through composer.

Install

Either run

$ php composer.phar require execut/yii2-migration "dev-master"

or add

"execut/yii2-migration": "dev-master"

to the require section of your composer.json file.

Usage

To use yii2 migration, simply expand the migration class from the execut\yii\migration\Migration class and override the abstract method:

 public function initInverter(\execut\yii\migration\Inverter $i)
 {
 }

$i has all the methods that normal migration has, but allows you to write actions up and down at a time.

To permanently do not rewrite the migration, you can define a new template for the yii migrate\create command.

 'controllerMap' => [
 'migrate' => [
 'templateFile' => '@vendor/execut/yii2-migration/views/template.php',
 ],

Supported databases

Currently only supported PostgreSQL and MySQL. Also you can use BDR plugin for PostgreSQL.
