Question

I have a Zend_Framework application, which has a whole bunch of model classes.

I need these model classes to be able to access the application’s database (naturally).

Currently I’ve put this in my index.php:

Zend_Registry::set('db',
        $application->bootstrap()->getBootstrap()
        ->getPluginResource('db')->getDbAdapter());

And then $db = Zend_Registry::get('db'); in each of my model classes that require the database.

But this seems like a horrible horrible hack. Am I missing something basic here?

Example of setting up SQLITE in your application.ini. You can also setup for MySQL or others.

resources.db.adapter = "PDO_SQLITE"
resources.db.params.dbname = APPLICATION_PATH "/../data/db/guestbook.db"

Once the db is loaded into the application you may extend the Zend_Db_Table_Abstract

class Application_Model_DbTable_Guestbook extends Zend_Db_Table_Abstract
{
    /** Table name */ 
    protected $_name    = 'guestbook';

    public function init() {
        $db = $this->getAdapter();

    }
}

You can use the zend methods…

        $select = $db->select()
         ->from(array('p' => 'products'),
                array('product_id', 'product_name'))
         ->join(array('l' => 'line_items'),
                'p.product_id = l.product_id');

Or you can do straight sql…

$sql = 'SELECT * FROM table1 t1 JOIN table2 t2 ON (t1.id = t2.id) JOIN table3 t3 ON (t3.id = t2.id);
$db->query($sql)->fetchAll(); 

All of this can be done in any model class that extends the Zend_Db_Table_Abstract
