README

Yii2 Framework extension for simplification of code generation when creating some migrations. Code for up- and down-method in migration class may be generated based on the name of migration or additional command line parameters.

Install

Install via composer:

composer require "fornit1917/yii2-emigrate:dev-master"

Then add ExtendedMigrateController in your controllerMap for console applications (file config/console.php):

    'controllerMap' => [
        'emigrate' => 'fornit1917\yii2emigrate\ExtendedMigrateController'
    ],

Now you can create migration with new yii2-emigrate:

./yii emigrate/create create_table_table_name

Usage

For automatic code generation migration it is necessary to give a special name:

• create_table_table_name - for creation table with name "table_name"
• drop_table_table_name - for dropping table with name "table_name"
• add_column_column_name_in_table_name - for adding new column with name "column_name" in table "table_name"
• drop_column_column_name_in_table_name - for dropping column with name "column_name" in table "table_name"

Create migrations for create table or drop table

./yii emigrate/create drop_table_table_name

This command generate the next code:

<?php

use yii\db\Schema;
use yii\db\Migration;

class m150105_202502_create_table_table_name extends Migration
{
    public function up()
    {
        $this->createTable('table_name', [], 'ENGINE=InnoDB CHARSET=utf8');
    }

    public function down()
    {
        $this->dropTable('table_name');
    }
}

If you do not need the option "ENGINE=InnoDB CHARSET=utf8", you can specify its value on the command line option tableOptions:

./yii emigrate/create **create_table_**table_name --tableOptions="ENGINE=MyISAM"

or empty value:

./yii emigrate/create **create_table_**table_name --tableOptions=0

The migration for drop table is generated similarly:

./yii emigrate/create drop_table_table_name

Create migrations for add column and drop column

./yii emigrate/create add_column_column_name_in_table_name

This command generate the next code:

<?php

use yii\db\Schema;
use yii\db\Migration;

class m150106_102312_add_column_column_name_in_table_name extends Migration
{
    public function up()
    {
        $this->addColumn('table_name', 'column_name', '');
    }

    public function down()
    {
        $this->dropColumn('table_name', 'column_name');
    }
}

Type of column is empty. This parameter can be specified in the command line option columnType:

./yii emigrate/create add_column_column_name_in_table_name --columnType="int(11) not null default 0"

This command generate the next code:

<?php

use yii\db\Schema;
use yii\db\Migration;

class m150106_102312_add_column_column_name_in_table_name extends Migration
{
    public function up()
    {
        $this->addColumn('table_name', 'column_name', 'int(11) not null default 0');
    }

    public function down()
    {
        $this->dropColumn('table_name', 'column_name');
    }
}

It is completely finished migration that does not require manual rework!

The migration for drop column is generated similarly:

./yii emigrate/create drop_column_column_name_in_table_name --columnType="int(11) not null default 0"

Command line options

The following command line options can be used:

• command
  • create-table
  • drop-table
  • add-column
  • drop-column
• table - name of table in migration
• tableOptions - options for Migration::createTable (for commands create-table and drop-table)
• column - name of column in migration (for commands add-column and drop-column)
• columnType - type of column in migration (for commands add-column and drop-column)

With these options, you can generate the migration not respecting the naming conventions. For example:

./yii emigrate/create my_cool_migration --command=add-column --column=column_name --columnType=int
