There is a Yii error I come across every now and again, and each time it stumps me.
If you ever get SomeModel.id not defined error when trying to put your dataprovider results into a cgridview or similar then it’s likely because
1) Your model doesn’t have an id column, it might use file_id or user_id etc instead and
2) You haven’t defined which other column should be used.
We do this using what’s known as keyField:
new CArrayDataProvider($users, array('keyField' => 'user_id')); new CSqlDataProvider($users, array('keyField' => 'user_id'));
