Larry, on page 150 of the YiiBook2 (latest version), you write that the following code is "verbose, redundant, and illogical": $model = new Page(); $model = $model->findOne($id); Instead of creating an instance of the Page class, as shown above, you say we should use a static class instance (or static method?), like this: if (($model = Page::findOne($id)) !== null) { return $model; etc. I don't understand why the first example is "verbose, redundant, and illogical", and why the second example is preferred. Can you please explain this? Thanks. -
Hi, I started reading the chapter about Document Object Model, and I have a few beginner questions: 1. Quote from book: Isn't HTML element the root node? 2.

I guess that's a mistake. Thank you in advance!

Version 0.5 Loading a Single Model The following two examples work together. The second calls the first. I believe the purpose is to retrieve a record from a table. And I believe each occurrence of $id represents the primary key value of the particular record we want. My question is, how do these functions know which table to search in? page 136: public function loadModel($id) { $model = Page::model()->findByPk($id); if ($model===null) { throw new CHttpException(404, 'The requested page does not exist.'); } Page 139: public function actionView($id){ $this->render('

Hi, I need to use a model with dynamic table name in my application. I have found a piece of code to use like that: $model = new DynamicModel($tableName); The code is as follows: class DynamicModel extends CActiveRecord { private static $_tableName; public function __construct($tableName) { if(strlen($tableName) == 0) { return false; } if(strlen($tableName)>0){ self::$_tableName = $tableName; } self::setIsNewRecord(true); } public static function model($tableName) { if(strlen($tableName) == 0) { return false; } $className=__CLASS__; if(strlen($tableName)>0){ se

Hi, I was hoping someone might have some experience using model inheritance in Yii. So far, I've only seen single table inheritance solutions (a la http://www.yiiframework.com/forum/index.php/topic/12775-unified-relational-model-into-one/page__p__63052#entry63052 and http://www.yiiframework.com/forum/index.php/topic/12978-class-table-inheritance/page__p__135262#entry135262). In practice, my requirements are only for a single level of inheritance. But in principle, the method prompts reservations. Before deciding on Yii as the framework, I spent a significant amount of time deciding
