i have two tables in my webapplication one for authentication and other for information of user. and thier relative models are User_authen and User_suthen_info it looks like this… i have innodb as mysql engin


class User_authen extends CActiveRecord

{


...


	 

	public function relations()

	{

		// NOTE: you may need to adjust the relation name and the related

		// class name for the relations automatically generated below.

		return array(

			'userAuthenInfo' => array(self::HAS_ONE, 'UserAuthenInfo', 'user_authen_id'),

		);

	}

    

...


}    





class User_authen_info extends CActiveRecord

{


...


	 

	public function relations()

	{

		// NOTE: you may need to adjust the relation name and the related

		// class name for the relations automatically generated below.

		return array(

			'userAuthen' => array(self::BELONGS_TO, 'UserAuthen', 'user_authen_id'),

		);

} 




My query 


       $post=User_authen_info::model()->findByPk(151);       

       $author=$post->userAuthen;

									  

	   var_dump($author);

	   exit;				

now when i var_dump to see what is the response it says

include(UserAuthen.php): failed to open stream: No such file or directory

i cant figure it out what is the problem… i am new to yii so don’t know how relations works… i have visited here

but i am unable to figure it out what is problem…

sorry guys it was just file name problem… it was dynamically generated so there file name was dynamic. so i have to change there file name to respective model names …
