Migration Generator

Latest Stable Version Total Downloads License

- generate migration files (not dumps!) with indexes, and foreign keys, for one table, comma separated list of tables, by part of table name, for all tables by - generate migrations based on table data - in two ways - as batchInsert Query or as insert via model - generate migrations based on PHPDOC and model properties



NOTE : Use 2.x versions for yii <=2.0.13

The preferred way to install this extension is through composer.

Either run

composer require --dev --prefer-dist insolita/yii2-migration-generator:~3.1

or add

"insolita/yii2-migration-generator": "~3.1"

to the require-dev section of your composer.json file.

Just install, go to gii and use (By default composer bootstrap hook)


In general the syntax of column definitions is based on style of yii-migration, only separated by "|" and provide a little more opportunities for reducing code - as you see in examples - empty brackets not necessary - also shortcut expr() will be replaced to defaultExpression() and default() to defaultValue

You can add annotations in your model(not necessary AR or yii\\base\\Model or Object or stdClass)

@db (db2) - specify connection id required for migration 'db' - by default"

@table ({{%my_table}})- specify table for migration"

__Supported column annotations:__ - As separate annotation above class or above current variable

 * @column (name) string|notNull|default('SomeValue')

- As addition to @property or @var definition

     * @var int $id @column pk()
    public $id;
     * @var string $route @column string(100)|notNull()
    public $route;

 * @property integer    $id         @column pk|comment("Id")
 * @property string     $username   @column string(100)|unique|notNull|default("Vasya")
 * @property string     $email      @column string(200)|unique()|defaultValue("")
 * @property string     $password   @column string(200)|notNull|expr(null)
 * @property string     $created_at @column string(200)|notNull|expr('CURRENT_TIMESTAMP')

Use Own templates

Copy default templates from folders

vendor/insolita/yii2-migration-generator/gii/default_structure //schema migrations

vendor/insolita/yii2-migration-generator/gii/default_data //data migrations

to some project directory, for example



Change gii configuration like this

$config['modules']['gii'] = [
    'class' => 'yii\gii\Module',
    'allowedIPs' => ['', 'localhost', '::1'],
    'generators' => [
        'migrik' => [
            'class' => \insolita\migrik\gii\StructureGenerator::class,
            'templates' => [
                'custom' => '@backend/gii/templates/migrator_schema',
        'migrikdata' => [
            'class' => \insolita\migrik\gii\DataGenerator::class,
            'templates' => [
                'custom' => '@backend/gii/templates/migrator_data',

Use own resolver for definition of columns

- create new class, inherited from \insolita\migrik\resolver\*ColumnResolver

- override required methods, or create methods for exclusive columns based on database types - see insolita\migrik\resolver\BaseColumnResolver resolveColumn() phpdoc and realization

Use own resolver for definition of indexes or relations

- create new class, inherited from \insolita\migrik\resolver\TableResolver - in bootsrap your apps add injection
