database migration in Yii

Question

In order to doing migration in Yii I used this lines

<?php

class m110714_122129_users extends CDbMigration
{
  public function up()
  {
        $this-> createTable('{{users}}',array(
   'id' => 'pk',
   'username' => 'VARCHAR (80) NOT NULL',
   'password' => 'VARCHAR (80) NOT NULL',
   'email' => 'VARCHAR (128) NOT NULL',
   'activekey' => 'VARCHAR (128) NOT NULL DEFAULT \'\'',
   'createtime' => 'INTEGER (10) NOT NULL DEFAULT \'0\' ',
   'lastvisit' => 'INTEGER (10) NOT NULL DEFAULT \'0\' ',
   'superuser' => 'INTEGER (1) NOT NULL DEFAULT \'0\' ',
    'status'=> 'INTEGER (1) NOT NULL DEFAULT \'0\' ',
));

  }

  public function down()
  {
    echo "m110714_122129_users does not support migration down.\n";
    return false;
  }

  /*
  // Use safeUp/safeDown to do migration with transaction
  public function safeUp()
  {
  }

  public function safeDown()
  {
  }
  */
}

To get

 CREATE TABLE IF NOT EXISTS `nt_users` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `username` varchar(20) NOT NULL,
      `password` varchar(128) NOT NULL,
      `email` varchar(128) NOT NULL,
      `activkey` varchar(128) NOT NULL DEFAULT '',
      `createtime` int(10) NOT NULL DEFAULT '0',
      `lastvisit` int(10) NOT NULL DEFAULT '0',
      `superuser` int(1) NOT NULL DEFAULT '0',
      `status` int(1) NOT NULL DEFAULT '0',
    );

But now I want to make some changes like doing unique key

UNIQUE KEY `username` (`username`),
  UNIQUE KEY `email` (`email`),
  KEY `status` (`status`),
  KEY `superuser` (`superuser`)

so how to make that? I searched Yii documentation but not found any thing. So any help will be highly appreciated..

Answer 1

Just supply them as non-associative values in the array like this:

$this-> createTable('{{users}}',array(
   'id' => 'pk',
   'username' => 'VARCHAR (80) NOT NULL',
   'password' => 'VARCHAR (80) NOT NULL',
   'email' => 'VARCHAR (128) NOT NULL',
   'activekey' => 'VARCHAR (128) NOT NULL DEFAULT \'\'',
   'createtime' => 'INTEGER (10) NOT NULL DEFAULT \'0\' ',
   'lastvisit' => 'INTEGER (10) NOT NULL DEFAULT \'0\' ',
   'superuser' => 'INTEGER (1) NOT NULL DEFAULT \'0\' ',
   'status'=> 'INTEGER (1) NOT NULL DEFAULT \'0\' ',
   'UNIQUE KEY `username` (`username`)',
   'UNIQUE KEY `email` (`email`)',
   'KEY `status` (`status`)',
   'KEY `superuser` (`superuser`)',
));

This way they will be added to the end of the create statement without any change.
