Question

Ok I am having real difficulty solving this. I’m trying to connect to a mysql database from a zend application and i receive the following error:

Message: No database adapter present

I have checked and double checked the connection credentials and they should be fine. The code should be fine too as it works ok in the development environment. If I deliberately change the password to be incorrect in the development environment, I get exactly the same error, which leads me to believe that maybe this is the case, despite my checking!

Any thoughts would be very welcome. If there’s nothing obviously wrong here then maybe I need to look at the server/db/php settings?

Thanks!

Bootstrap code:

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initPlaceholders(){
    Zend_Session::start();

    $this->bootstrap('View');
    $view = $this->getResource('View');

    $view->doctype('XHTML1_STRICT');

    // Set the initial stylesheet:
    $view->headLink()->appendStylesheet('/css/global.css');

    $autoloader = Zend_Loader_Autoloader::getInstance();
    $autoloader->registerNamespace('Pog_');


    Zend_Controller_Action_HelperBroker::addPath(
    APPLICATION_PATH . '/controllers/helpers',
        'Application_Controller_Action_Helper_');

}


}

Config file:

[production]
phpSettings.display_startup_errors = 0
phpSettings.display_errors = 0
includePaths.library = APPLICATION_PATH "/../library"
bootstrap.path = APPLICATION_PATH "/Bootstrap.php"
bootstrap.class = "Bootstrap"
appnamespace = "Application"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.params.displayExceptions = 0
resources.view[] =

database.adapter         = pdo_mysql
database.params.host     = localhost
database.params.username = user
database.params.password = password
database.params.dbname   = test

DB connection helper:

/**
 * Constructor: initialize plugin loader
 *
 * @return void
 */
public function __construct()
{
    try{

        $config = new Zend_Config_Ini(APPLICATION_PATH . '/configs/application.ini', 'production');
        $dbAdapter = Zend_Db::factory($config->database);
        $dbAdapter->getConnection();
        $this->connection = $dbAdapter;
    } catch (Zend_Db_Adapter_Exception $e) {
        echo 'perhaps a failed login credential, or perhaps the RDBMS is not running';
    } catch (Zend_Exception $e) {
        echo 'perhaps factory() failed to load the specified Adapter class';
    }
}
public function getDbConnection(){
    return $this->connection;
}
}

Define your database as a resource

resources.db.adapter = pdo_mysql
resources.db.params.host = localhost
resources.db.params.username = user
resources.db.params.password = password
resources.db.params.dbname = test

In your main files you then need to do nothing but initiate a query without having to worry about assigning the database fvrom your config – its done in the inside, the DB resource is always chosen as the default adapter for your database transactions
