Yii2 Tips and Tricks

  • [Ok, I have an error `"unexpected '[', expecting ')' in ../vendor/yiisoft/yii2/yii/Yii.php on line 25"`](https://github.com/yiisoft/yii2/issues/2582) > Hey man just use PHP 5.4 :)

  • Url Rule To Catch All > '<action:\w+><data:(.*)?>' => 'site/<action>'

  • Confused with "use Yii;" in view file > cebe : use Yii; is to import Yii class into the current namespace. As the view file is already in the root namespace where also the Yii class lives there is not sense of importing it. Thus the error.

  • How can I add relationships on fly in Yii2 ? > qiang : I see. So your relation name is dynamic based on the configuration, right? You need to do some trick with your behavior to support such "dynamic method". override Behavior::hasMethod() to return true for getRelationName. override Behavior::__call() to implement getRelationName.

  • Adding default scope to AR > Yes in Yii2 is dropped, because this method make many problems. You can simple add default scope, e.q ~~~{.php} class Post extends ActiveRecord { public static function createQuery($config = []) { $config['modelClass'] = get_called_class(); return (new PostQuery($config))->active(); } }

class PostQuery extends ActiveQuery { public function active() { $this->andWhere(['status' => Post::STATUS_PUBLISHED]); return $this; } } ~~~
