Using cache in CActiveDataProvider

Updated 3 years ago by StammTips7 comments – viewed 14,548 times – ( +20 ) – version 1.1
First param in CActiveDataProvider could be a string with model name or instance of class. So, you may use CActiveRecord::cache() for cache, but you need set third param to 2, because you should cache 2 queries: counting and get data.

Customizing Yii's formatting rules (extending CFormatter)

Updated 3 years ago by HaenselTips0 comments – viewed 12,907 times – ( +14 ) – version 1.1

More or less I use auto-complete field for a form. CJuiAutoComplete is a yii widget for this purposes. The common use case is to make an ajax request and retrieve a list from the database.

Sometimes it would be nice if we could run yiic from an action, for example a migrate database button in our admin panel. Or because you are on a host which doesn't have shell access. Or maybe you are not allowed run popen or exec.
