modify database.php like this

Code:
$active_group = 'default';

$active_record = TRUE;

$db['default']['hostname'] = 'localhost';

$db['default']['username'] = 'username';

$db['default']['password'] = 'password';

$db['default']['database'] = 'dbname';

$db['default']['dbdriver'] = 'mysql';

$db['default']['dbprefix'] = '';

$db['default']['pconnect'] = FALSE;

$db['default']['db_debug'] = FALSE;

$db['default']['cache_on'] = FALSE;

$db['default']['cachedir'] = '';

$db['default']['char_set'] = 'utf8';

$db['default']['dbcollat'] = 'utf8_general_ci';

$db['default']['swap_pre'] = '';

$db['default']['autoinit'] = TRUE;

$db['default']['stricton'] = FALSE;

$db['test']['hostname'] = 'localhost';

$db['test']['username'] = 'username';

$db['test']['password'] = 'password';

$db['test']['database'] = 'dbname';

$db['test']['dbdriver'] = 'mysql';

$db['test']['dbprefix'] = '';

$db['test']['pconnect'] = FALSE;

$db['test']['db_debug'] = FALSE;

$db['test']['cache_on'] = FALSE;

$db['test']['cachedir'] = '';

$db['test']['char_set'] = 'utf8';

$db['test']['dbcollat'] = 'utf8_general_ci';

$db['test']['swap_pre'] = '';

$db['test']['autoinit'] = TRUE;

$db['test']['stricton'] = FALSE;

modify your model like this

Code:
class Testmodel extends Model {

 public $DB2;

 function Testmodel(){

  parent::Model();

  $this->DB2 = $this->load->database('test', TRUE); 

 }

 function get_cities()

    {

  $this->DB2->order_by('id');

  $this->DB2->select('id, name');

  $result_areas = $this->DB2->get('cities');

  return $result_areas->result();

    }

Here's one I did for changing the database config for local and live server!

Code:
if (defined('ENVIRONMENT'))

{

 switch (ENVIRONMENT)

 {

  case 'development':

   $active_group  = 'default';

  break;

  case 'testing':

  case 'production':

   $active_group = 'live';

  break;

  default:

   $active_group  = 'default';

  break;

 }

}

else

{

 $active_group  = 'default';

}

$active_record = TRUE;

// Local Server.

$db['default']['hostname'] = 'localhost';

$db['default']['username'] = 'username';

$db['default']['password'] = 'password';

$db['default']['database'] = '';

$db['default']['dbdriver'] = 'mysql';

$db['default']['dbprefix'] = '';

$db['default']['pconnect'] = FALSE;

$db['default']['db_debug'] = TRUE;

$db['default']['cache_on'] = FALSE;

$db['default']['cachedir'] = '';

$db['default']['char_set'] = 'utf8';

$db['default']['dbcollat'] = 'utf8_general_ci';

$db['default']['swap_pre'] = '';

$db['default']['autoinit'] = TRUE;

$db['default']['stricton'] = FALSE;

// Live Server.

$db['live']['hostname'] = 'localhost';

$db['live']['username'] = 'username';

$db['live']['password'] = 'password';

$db['live']['database'] = '';

$db['live']['dbdriver'] = 'mysql';

$db['live']['dbprefix'] = '';

$db['live']['pconnect'] = FALSE;

$db['live']['db_debug'] = TRUE;

$db['live']['cache_on'] = FALSE;

$db['live']['cachedir'] = '';

$db['live']['char_set'] = 'utf8';

$db['live']['dbcollat'] = 'utf8_general_ci';

$db['live']['swap_pre'] = '';

$db['live']['autoinit'] = TRUE;

$db['live']['stricton'] = FALSE;

If you are creating production and development databases then just make a folder for each environment and drop in a database.php file into each one and make the changes to that. CI already has that functionality.
