How to create your own feature migration in yii2

Question

This is the default code for migration

<?php

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

class m150101_185401_create_news_table extends Migration
{
    public function up()
    {
        $this->createTable('news', [
            'id' => Schema::TYPE_PK,
            'title' => Schema::TYPE_STRING . ' NOT NULL',
            'content' => Schema::TYPE_TEXT,
        ]);
    }

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

here TYPE_TEXT is a predefined attribute, since I can create my own trait, for example int (11) Not NULL, unsigned unsignedInt, there is a way to create my own traits.

To do this, you can define your personal SchemaBuilderTraits in the correct namespace and remember this in your code

look at this yii2 document http://www.yiiframework.com/doc-2.0/yii-db-schemabuildertrait.html

https://github.com/yiisoft/yii2/blob/master/framework/db/Migration.php

In Migration.php, you can easily view the call to use in the first line.

yii\db\SchemaBuilderTrait . 2.0.6.
