当我在UserIdentity中使用此代码时
$users=array(
// username => password
'demo'=>'demo',
'admin'=>'admin',
);
$users = Pi::model()->findByAttributes(array('username'=>$this->username));
Fatal error: Call to undefined method Pi::model() in C:\xampp\htdocs\pro_c\protected\components\UserIdentity.php on line 47
请帮帮我，您有一个名为User的模型，属于CFormModel类型（它是一个表单模型）。但是您正在尝试访问用于CActiveModel类型的User:：model（）->FindByatAttributes（数据库模型）。您应该将类用户重命名为其他名称。例如，这里的用户类称为UserIdentity。
您必须对代码进行一些更改才能正常工作。只需查看Yii博客演示，就可以找到正确的方向。您的代码似乎在正确的路径上，但Yii似乎无法找到用户类 您可以手动导入该类，或者更好的是，使用protected/config/main文件中的“import”指令自动加载该类 这会告诉yii加载受保护的/models/目录中的所有模型，假设User.php类文件位于该目录中
