Laravel - change the default database connection globally

Question

In my database.php, I have TWO databases configured.

\'db1\' => array(
  \'driver\'   => \'pgsql\',
  \'host\'     => \'localhost\',
           


        

Answer 1

Config::set is only going to work on a per-request basis, so you're probably going to want to set your database in the Session and grab it on subsequent requests.

You have some options on where to do that. /app/start/global would be one option. In the controller constructor would be another. You could register a service provider to do it, too.

Below is an example of what the code might look like [warning: untested code!] in the controller constructor:

   public function __construct() {
     if(Session::has('selected_database'){
        Config::set('database.default',Session::get('selected_database'));
     } else {
        return Redirect::to('database_choosing_page');
     }
   }

and an update to your database setting function:

public function postChangeDb()  {
    $db = Input::get('db');
    Session::put('selected_database',$db);
    Config::set('database.default', $db);
}

Answer 2

Have you tried simply to change the default connection in app/config/database.php?

'default' => 'db2'

If it's not the case then please provide more information on the problem.

Edit: So it seems you have all connections hardcoded in the models. Try updating the models like that:

    protected $connection = 'db2';
