how best to use two databases in cakephp 2.3? - mongodb

Question

I am using two databases in an application that I am creating in cakephp 2.3. A mysql database, which typically configured, and another database nosql (MongoDB), I use this way for example:
$connection = new Mongo('localhost');
$db = $connection->compras;
return $db->anuncios->insert($dados);
can I use this way?
about security ..., what possible problems that you guys realize to use mongo database that way?

Answer 1

You've to setup environment in the app/Config/Core.php file which mean which database you want to use in which mode i.e. Production, Development, staging etc with below
if(env('HTTP_HOST')):
switch (env('HTTP_HOST')) {
case "example.com":
case "www.example.com":
define('DEVELOPMENT_MODE', false); // Suppose you're using production for Mysql databse
break;
case "development.example.com":
define('DEVELOPMENT_MODE', true); // Suppose you're using development for MongoDB
break;
default:
define('DEVELOPMENT_MODE', true);
break;
}
After that you've to use DEVELOPMENT_MODE variable in the app/Config/database.php file as below i.e.
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'db_username',
'password' => 'db_password',
'database' => 'db_name',
//'prefix' => '',
'encoding' => 'utf8',
);
var $mongo = array(
'datasource' => 'mongodb.mongodbSource',
'persistent' => false,
'host' => 'localhost',
'login' => 'db_username',
'password' => 'db_password',
'database' => 'db_name',
//'prefix' => '',
'encoding' => 'utf8',
);
public function __construct() {
if (DEVELOPMENT_MODE) {
$this->default = $this->mongo;
} else {
$this->default = $this->default;
}
}
}
All the above logic are use for Config settings to use through out application.
Now below code is connect Model to mongoDB.
class Test extends AppModel {
var $name = 'test';
var $primaryKey = 'id';
var $useDbConfig = 'mongo'; // setup the mongodb datasource
// Now is model is connected with mongoDB only....
}
