[fw-db] How to i reference the database adapter in my controllers?

I have this function iside one of my controllers;

 

public function getAuthAdapter(array $params)

    {

       

      $authAdapter = new Zend_Auth_Adapter_DBTable(

            $db,

            'USERS',

            'USERNAME',

            'PASSWORD'

        );

       

        // Set the input credential values (e.g., from a login form)

            $authAdapter->setIdentity($params['username'])

                        ->setCredential($params['password']);

     

                       

        return $authAdapter;

       

    }

 

I assume I need to make $db refer to my database adapter? But I am unsure of how I do that.

My database connection is defined in my application.ini file, and I am using the autoloader (but I don’t really understand the inner workings of it all).

 

Sorry if this is not clear.
