An important tip when you are using CArrayDataProvider.

Updated 8 months ago by Maurizio Domba CerinTips0 comments – viewed 13,690 times – ( +8 / -2 ) – version 1.1
Yii's CArrayDataProvider is very helpful to display model relation data's directly on it.But it is truely a confusing one because by default it will assume a table field named “id” as primary key for its pagination purpose and what if you dont have field named “id” as primary key on your table? so its truely confusing and if you tried to display without an “id” field on ur table you will get an error like “yourmodel.id is not defined”.
