Yii configuration: Dynamic & User dependent

Updated 5 months ago by le_topHow-tos0 comments – viewed 2,469 times – ( +1 ) – version 1.1
It is difficult to perform user dependent theming through a general configuration in 'main.php'. This article proposes a method to do so through a Factory that dynamically generates classes to allow delayed resolution of actual user values. This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded.

Getting to Understand Hierarchical RBAC Scheme

Updated 6 months ago by rAWTAZTutorials15 comments – viewed 79,607 times – ( +62 ) – version 1.1

I found how to define authorization hierarchy, how business rules are evaluated, how to configure authManager, but almost nothing about how I should build my hierarchy, in what sequence its nodes are checked, when the checking process stops and what would be the checking result.
