Yii CActiveDataProvider with（）和加入

Question

I want to have separate row for each related object in CGridView.

ModelB has modelAId, so it is HAS_MANY relationship.

The following query returns what I am trying to get:

select * from modelA a
join modelB b on b.modelAId = a.id

Here I am getting separate rows for each corresponding modelB row, records from modelA may be duplicated.

However, The following provider is not returning expected records, how can I make use of this in CActiveDataProvider

$provider = new CActiveDataProvider ("ModelA", array ("criteria" => array (
            "with" => array("ModelB")
            )
        ));

If I add join "join" => " join modelB b on b.modelAId = t.id", and remove with() it is giving correct records, but when I include with() it only gives modelA records.

What is the correct way of getting data from ModelA INCLUDING separate rows for ModelB relation?

Answer 1

You can use cDbCriteria to that in ultimate easy fashion

$criteria=new cDbCriteria();
$criteria->with=array('ToModelB'); //Here ToModelB is defined relation in ModelA to ModelB
$dataProvider=new CActiveDataProvider('ModelA',array('criteria'=>$criteria));

But before that make sure you have proper relations defined for these two models.
