Question

I have a complex data structure that means I have not been able to fully use relationships defined in schema.yml for my model.

Now I have some reporting queries which need to use tables from several databases.

Because of the complexity of the model these queries are written in raw sql. So I need to use the database names in the query in order to select the correct databases for various tables.

I am using symfony 1.4 and Doctrine 1.2

How can I extract the database names for my current environment (Prod, Dev, Test etc) from databases.yml in order to use them in the raw sql queries?

Im sure there must be a better way, but turns out you can get the DSN from sfDatabaseManager. So until I find a proper way, I’ve extended sfDatabaseManager to add the following getDsn method

class sfDatabaseManagerExt extends sfDatabaseManager
{
  public function getDsn($conn)
  {  
    $db = $this->getDatabase($conn);
    $dsn = $db->getParameter('dsn');
    return $dsn;
  }


}

Then in the model where I need to get the database name for a specific connection and environment:

$appConfig= ProjectConfiguration::getApplicationConfiguration(sfConfig::get('sf_app'),      sfConfig::get('sf_env'), false);     
$dbManager= new sfDatabaseManagerExt($appConfig);      
$dsn=$dbManager->getDsn('doctrine');

Just need to explode / regex on the dsn then to get the dbname.

I would LOVE it if someone would post to tell me how rubbish this is, but of course only if they have a better solution! I have looked, and looked and looked….
