Question

I have database relation as follows between question table and Hardware detail table.
Question and HardwareDetail has many to many relation. and tbl_quesionhardwaredetial table holds another new property called answer

I want to create active data provider (CActiveDataProvider) with list of questions and relevant answers for a given hardware detail.

I have pull relevant questions for a given hardware detail using following criteria.

$quesionsDataProvider=new CActiveDataProvider('Question', array(
            'criteria'=>array(
                'with'=>array('hardwaredetails'=>array( 
                        'on'=>'hardwaredetail_Id=' .$modelHD->Id, 
                        'together'=>true,
                        'joinType'=>'INNER JOIN', 
                )),
            ),
            'pagination'=>array(
                'pageSize'=>10,
            ),
        ));

But how can i attach the answer to the list of questions retrieved.

Thanks in advance for any help

Answer 1

Instead of creating CActiveDataProvider you can create CSqlDataProvider which is more flexible and you can write sql queries by hand

Example:

$dataProvider = new CSqlDataProvider($qry, array(
                'keyField' => 'id',
                'totalItemCount' => $count,
                'sort' => array(
                    'attributes' => array('field1','field2')
                ),
                'pagination' => array(
                    'pageSize' => 5
                )
                    )
    );

$qry = your sql query for selecting records

$count = no of records(you should modify above $qry to find record count)

‘keyField’= you should mention keyField, if you use different primary key field other than ‘id’
