Multiple database in cakephp console app - php

Question

Following is my cake console code to generate database schema. I have to manage multiple database schema migration. When I am calling generateDb function it creates a master schema after that i am switching database connection to client database, but client schema is not generating. its again generating master schema.
class HelloShell extends AppShell {
public $uses = array('ClientDbdetail');
public function generateDb() {
$runCommand = shell_exec(APP.'Console/cake schema generate -f master');
if ($runCommand) {
$sessionArray = $this->ClientDbdetail->find('first', array('recursive' => -1));
$this->__switchDb($sessionArray['ClientDbdetail']);
shell_exec(APP.'Console/cake schema generate -f client');
$this->out('Schema generated');
} else {
$this->out('Schema not generated');
}
}
private function __switchDb(array $userDetail) {
$username = 'default';
$settings = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'port' => 3306,
'login' => $userDetail['user_dbuser'],
'password' => $userDetail['user_dbpwd'],
'database' => $userDetail['user_dbname'],
'prefix' => ''
);
ConnectionManager::drop($username);
ConnectionManager::create($username, $settings);
ConnectionManager::getDataSource($username);
}
}

From CakePHP book there is an example.
public $connection = 'default';
public function before($event = array()) {
$db = ConnectionManager::getDataSource($this->connection);
$db->cacheSources = false;
return true;
}
and after :
public function before($event = array()) {
$articles = ClassRegistry::init('Articles', array(
'ds' => $this->connection
));
// Do things with articles.
}
