Question

How to make two or more database connections in Yii mongodbsuite?

I added 2 DB components in main.php:

'components' => array(

    'mongodb' => array(
        'class'             => 'common\extensions\MongoDB',
        'connectionString'  => 'mongodb://localhost:27017/table1',
        'dbName'            => 'table1',
        'fsyncFlag'         => false,
        'persistentConnection' => 'x',
        'replicaSet'        => false,
        'safeFlag'          => true,
        'useCursor'         => false,
    ),

    'mongodb2' => array(
        'class'             => 'common\extensions\MongoDB',
        'connectionString'  => 'mongodb://localhost:27017/table2',
        'dbName'            => 'table2',
        'fsyncFlag'         => false,
        'persistentConnection' => 'x',
        'replicaSet'        => false,
        'safeFlag'          => true,
        'useCursor'         => false,
    ),

)

But how to use mongodb2 in query (ex: ->findByAttributes()) i don’t know.
Please provide some example queries using the mongodb2 connection above.

Answer 1

I just add ‘mongodb2’ => array to ‘components’ => array and add to models (ex: User) who extends EMongoDocument:

public function getMongoDBComponent() {return Yii::app()->mongodb2;}

And it is work!
