About error messages and locales

Localization
1. create file for localization
/protected/messages/
/en/default.php
/cn/default.php
/jp/default.php

2. specific a lang
Yii::app()->language = "en"
: this means your en folder under /protected/messages.

3. in your default.php, write things as follows,

return array(
'name' => 'xing ming',
'required' => 'bu neng wei kong',
);
?>

4. anywhere you want to use the localized name, write,

Yii::t('default', 'name');

custum error message.
1. in your model/Model.php, find function rules.
return array(
array('name, mail', 'required', 'message' => Yii::t('default', 'required'); ),
);

2. This tag will show all the form errors in a block.
The second param is the title of the block.
Here I leave it blank.
errorSummary($model, ""); ?>

Yii - default timezone

1.set default timezone
Encountered an error which was described here:
http://php.net/manual/en/function.date-default-timezone-set.php
I added the following line to the index.php
date_default_timezone_set("Asia/Tokyo");

2.Gii

'modules'=>array(
'gii'=>array(
'class'=>'system.gii.GiiModule',
'password'=>'123456',
'ipFilters'=> array('localhost', '127.0.0.1', '192.168.2.249'),
),
),

3. Gii
"CDbConnection failed to open the DB connection: could not find driver"
I didn't get the proper pdo_php support.
I re-configured php using the following command:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-pdo-mysql

...fixed now
