class User extends CActiveRecord { public function __construct($scenario='insert') { parent::__construct($scenario); $this->status = 'active'; } // ... }
class Post extends CActiveRecord { public function __construct($modelClass=null) { if ($modelClass === null) { $modelClass = 'Post'; } parent::__construct($modelClass); } // ... }In this example, we override the __construct method to allow the Post model to be instantiated with a different model class name. This can be useful in certain scenarios, such as when creating a base model class that other models can inherit from. Package/Library determination: The CActiveRecord class is part of the Yii framework's database library. It is used to provide an Object Relational Mapping (ORM) layer between PHP and a database.
