Validation rules ActiveRecord CModel

http://www.yiiframework.com/doc/guide/1.1/en/form.model#declaring-validation-rules

We specify the validation rules in the rules() method which should return an array of rule configurations.

   1  public function rules()
   2     {
   3         return array(
   4             array('username, password', 'required'),
   5             array('rememberMe', 'boolean'),
   6             array('password', 'authenticate'),
   7         );
   8     }

Relations ActiveRecord

http://www.yiiframework.com/doc/guide/1.1/en/database.arr#declaring-relationship

Override the relations() method of CActiveRecord.

Types relationship:

• self::BELONGS_TO
• self::HAS_MANY
• self::HAS_ONE
• self::MANY_MANY

   1 public function relations()
   2     {
   3         return array(
   4             'posts'=>array(self::HAS_MANY, 'Post', 'author_id'),
   5             'profile'=>array(self::HAS_ONE, 'Profile', 'owner_id'),
   6         );
   7     }
