为了做migration in Yii,我使用了这一行
<?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()
{
}
*/
}
获得
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',
);
但现在我想做一些改变,比如做独特的密钥
UNIQUE KEY `username` (`username`),
UNIQUE KEY `email` (`email`),
KEY `status` (`status`),
KEY `superuser` (`superuser`)
那怎么做呢?我搜索了Yii文档,但没有找到任何东西。所以任何帮助都将受到高度赞赏..

只需在数组中将它们作为非关联值提供,如下所示:
$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`)',
));
这样它们将被添加到create语句的末尾而不做任何更改。

$this->createTable('{{users}}',
array(
'id' => 'pk',
'username' => 'varchar(80) NOT NULL',
'password' => 'varchar(80) NOT NULL',
'email' => 'varchar(128) NOT NULL',
'activkey' => '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\'',
),
);
$this->createIndex('username', '{{user}}', 'username', true);
$this->createIndex('email', '{{user}}', 'email', true);
$this->createIndex('superuser', '{{user}}', 'superuser', false);
$this->createIndex('status', '{{user}}', 'status', false);
