Cassandra connection in Yii

[Neerja Negi]

Hi All,

 I was trying to connect my cassandra db connection in Yii.

I edited my main.php file and added the lines given below:

'cassandra' => array

  (

  'class' => 'ext.yii-cassandra-cql3.ACassandraConnection',

  'connectionString'=>'cassandra:host=xxx.xxx.xxx.xxy;port=8080,

                host=xxx.xxx.xxx.xxq;port=9160,

                host=xxx.xxx.xxx.xxw;port=9160,

                host=xxx.xxx.xxx.xxe;port=9160,

                host=xxx.xxx.xxx.xxr;port=9160:dbname=nn_db',

  'username' => 'username',

  'password' => 'password', 

  ),

TempController.php

public function actiontestpages()

{

 //echo "zeroo";die;

 $query_result = Yii::app()->cassandra->cql3_query("Select emop_name from emp_table where emp_id =:emp_id;");

 echo "first";

 $query_result->bindParam(':emp_id',$this->emp_id,PDO::PARAM_INT);

 echo "second";

 $rows = Yii::app()->cassandra->cql_get_rows($query_result);

 echo "third";

 print_r($rows);

 die;

}

When i uncommented the first line i.e.  //echo "zeroo";die; i got an 500 error given below:

Array ( [code] => 500 [type] => CException [errorCode] => 0 [message] => Property "ACassandraConnection.connectionString" is not defined.  [file] => /wservce/framework/YiiBase.php [line] => 220

Please help me out.
