This article is for those who have dealt with the complexity of Elasticsearch or any other indexing machines and are looking for an easier way to index the existing database without additional effort.

Please consider the following Dear software engineers imagine I have a simple ISA hierarchy: parent A with children B and C. So let's say we have the corresponding tables named "a", "b", "c" and (created with the help of the gii model creator) the classes A, B, C The following is a screenshot from MySQL workbench: ![MySQL workbench screenshot](http://s4.postimage.org/4tuwkm43d/Screenshot.pn...

CMenu comes with a lot of great customization options built in. One of the most used is the class 'active' being added to menu item. But, what if you want to add your own class or id to a menu item ?

In order to get your Yii logs into Heroku's logs, you have to work a little bit of magic.

This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded. The values will be fetched...
