yii新手在实例化models(controller调用models实化化)php warning错误

新手在执照yii教程来的时候，config/main.php文件是全新写的，post提交的时候，会出错

include(LoginForm.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory

需要在config/main.php文件里设置，增加：

'import'=>array(
        'application.models.*',
        'application.components.*',
    ),
