1、文件路径：advanced/console/migrations/m130524_201442_init.php
2、补充点：增加约束“username”“email”验证的唯一性：
原代码：
<?php
use yii\db\Schema;
use yii\db\Migration;
class m130524_201442_init extends Migration
{
public function up()
{
$tableOptions = null;
if ($this->db->driverName === ‘mysql‘) {
// http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci
$tableOptions = ‘CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB‘;
}
$this->createTable(‘{{%user}}‘, [
‘id‘ => Schema::TYPE_PK,
‘username‘ => Schema::TYPE_STRING . ‘ NOT NULL‘,
‘auth_key‘ => Schema::TYPE_STRING . ‘(32) NOT NULL‘,
‘password_hash‘ => Schema::TYPE_STRING . ‘ NOT NULL‘,
‘password_reset_token‘ => Schema::TYPE_STRING,
‘email‘ => Schema::TYPE_STRING . ‘ NOT NULL‘,
‘status‘ => Schema::TYPE_SMALLINT . ‘ NOT NULL DEFAULT 10‘,
‘created_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘,
‘updated_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘,
], $tableOptions);
}
public function down()
{
$this->dropTable(‘{{%user}}‘);
}
}
补充后的代码：
<?php
use yii\db\Schema;
use yii\db\Migration;
class m130524_201442_init extends Migration
{
public function safeUp()
{
$tableOptions = null;
if ($this->db->driverName === ‘mysql‘) {
// http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci
$tableOptions = ‘CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB‘;
}
$this->createTable(‘{{%user}}‘, [
‘id‘ => Schema::TYPE_PK,
‘username‘ => Schema::TYPE_STRING . ‘ NOT NULL‘,
‘auth_key‘ => Schema::TYPE_STRING . ‘(32) NOT NULL‘,
‘password_hash‘ => Schema::TYPE_STRING . ‘ NOT NULL‘,
‘password_reset_token‘ => Schema::TYPE_STRING,
‘email‘ => Schema::TYPE_STRING . ‘ NOT NULL‘,
‘status‘ => Schema::TYPE_SMALLINT . ‘ NOT NULL DEFAULT 10‘,
‘created_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘,
‘updated_at‘ => Schema::TYPE_INTEGER . ‘ NOT NULL‘,
], $tableOptions);
$this->createIndex(‘username‘, ‘{{%user}}‘, ‘username‘, true);
$this->createIndex(‘email‘, ‘{{%user}}‘, ‘email‘, true);
}
public function safeDown()
{
$this->dropTable(‘{{%user}}‘);
}
}
