我正在尝试获取business表视图中的username，即userbusiness.php。Business表与user表没有关系，但与reviewbusiness表有一对多关系。此外，Reviewbusiness与用户表具有一对多关系。Review business具有以下属性：user_id、business_id、rating、review。我的问题是，如何在business视图（userbusiness.php）中获得与user表没有关系的username？
这是我的商业模式

我认为你可以通过这种方式简单地获得用户名
Yii::app()->user->name;
你也可以通过这种方式获得用户id
Yii::app()->user->getId();
查看此文档表单了解更多信息http://www.yiiframework.com/doc/api/1.1/CWebUser/
为了检索给定userId的用户名，你可以这样做
$theUsername = User::model()->find('id=:id',array(':id'=>$yourid))->username;
