/*
/www/yii_dev/yii/framework# php yiic migrate help
Error: Unknown action: help
USAGE
yiic migrate [action] [parameter]
DESCRIPTION
This command provides support for database migrations. The optional
'action' parameter specifies which specific migration task to perform.
It can take these values: up, down, to, create, history, new, mark.
If the 'action' parameter is not given, it defaults to 'up'.
Each action takes different parameters. Their usage can be found in
the following examples.
EXAMPLES
* yiic migrate
Applies ALL new migrations. This is equivalent to 'yiic migrate to'.
* yiic migrate create create_user_table
Creates a new migration named 'create_user_table'.
* yiic migrate up 3
Applies the next 3 new migrations.
* yiic migrate down
Reverts the last applied migration.
* yiic migrate down 3
Reverts the last 3 applied migrations.
* yiic migrate to 101129_185401
Migrates up or down to version 101129_185401.
* yiic migrate mark 101129_185401
Modifies the migration history up or down to version 101129_185401.
No actual migration will be performed.
* yiic migrate history
Shows all previously applied migration information.
* yiic migrate history 10
Shows the last 10 applied migrations.
* yiic migrate new
Shows all new migrations.
* yiic migrate new 10
Shows the next 10 migrations that have not been applied.

在我们开发程序的过程中，数据库的结构也是不断调整的。我们的开发中要保证代码和数据库库的同步。因为我们的应用离不开数据库。例如: 在开发过程中，我们经常需要增加一个新的表，或者我们后期投入运营的产品，可能需要为某一列添加索引。我们必须保持数据结构和代码的一致性。如果代码和数据库不同步，可能整个系统将无法正常运行。出于这个原因。yii提供了一个数据库迁移工具，可以保持代码和数据库是同步。方便数据库的回滚和更新。
功能正如描述。主要提供了数据库迁移功能。
命令格式
yiic migrate [action] [parameter]
action参数用来制定执行哪一个迁移任务。可以一使用
up, down, to, create, history, new, mark.这些命令
如果没有action参数，默认为up
parameter根据action的不同而有所变化。
上述例子中给出了说明。
官方也给出了详细的例子。
http://www.yiiframework.com/doc/guide/1.1/zh_cn/database.migration#creating-migrations
这里不再详细累述。用到的时候参考使用就可以了。
补充：yii2.0使用migrate创建后台登陆
重新创建一张数据表来完成后台登陆验证
为了大家看得明白，直接贴代码
一、使用Migration创建表admin
console\\migrations\\m130524_201442_init.php

}
public function safeDown()

}
}

使用命令行来创建admin数据库
1、win7下使用命令：
在项目根目下，右键选择User composer here(前提是安装了全局的composer)，
yii migrate
即创建数据表 admin成功
2、linux下命令一样（此处略）
二、使用gii创建模型
此处略，很简单的步聚。
注：把admin模型创在 backend/models下面 （放哪里看个人喜好）
代码如下

三、使用migrate 为后如初使化一个登陆帐号
1、console\\controllers创建InitController.php

/**
*
* @author chan <maclechan@qq.com>
*/
namespace console\\controllers;
use backend\\models\\Admin ;
class InitController extends \\yii\\console\\Controller
{
/**
* Create init user
*/
public function actionAdmin()
{
echo "创建一个新用户 ...\\n"; // 提示当前操作
$username = $this->prompt('User Name:'); // 接收用户名
$email = $this->prompt('Email:'); // 接收Email
$password = $this->prompt('Password:'); // 接收密码
$model = new AgAdmin(); // 创建一个新用户
$model->username = $username; // 完成赋值
$model->email = $email;
$model->password = $password;
if (!$model->save()) // 保存新的用户
{
foreach ($model->getErrors() as $error) // 如果保存失败，说明有错误，那就输出错误信息。
{
foreach ($error as $e)
{
echo "$e\\n";
}
}
return 1; // 命令行返回1表示有异常
}
return 0; // 返回0表示一切OK
}
}
|
2、使用命令：
在项目根目下，右键选择User composer here(前提是安装了全局的composer)，
yii init/admin
到此，打开数据表看下，己经有了数据。
四、后台登陆验证
1、backend\\controllers\\SiteController.php 里actionLogin方法不用变
2、把common\\models\\LoginForm.php复制到backend\\models只要把LoginForm.php里面的方法getUser()修改一个单词即可，如下
?

|
public function getUser()
{
if ($this->_user === false) {
$this->_user = Admin::findByUsername($this->username);
}
return $this->_user;
}
|
3、backend\\config\\main.php 只要修改
?
|
1

4
|
'user' => [
'identityClass' => 'backend\\models\\Admin',
'enableAutoLogin' => true,
],
