Zend Framework using regular mysql select call - zend-db

Question

Is there a way to use a regular mysql select statement with Zend Framework without having to use Zend_Db::factory
Code below is in my Model classes which extends Zend_Db_Table_Abstract
I can currently do this (which works):
$db = Zend_Db::factory('Pdo_Mysql', array(
'host' => 'localhost',
'username' => 'dbuser',
'password' => 'dbuserpass',
'dbname' => "somedbname"
));
$select = "SELECT iv.*
FROM image_variations AS iv
LEFT JOIN images AS i ON (i.image_id = iv.image_id)
LEFT JOIN product_images AS pi ON (pi.image_id = iv.image_id)
WHERE pi.pid = '$pid'
&& iv.image_type_id = '$image_type_id' ";
$stmt = $db->query($select);
$rows = $stmt->fetchAll();
return $rows;
I would like to do this:
$select = "SELECT iv.*
FROM image_variations AS iv
LEFT JOIN images AS i ON (i.image_id = iv.image_id)
LEFT JOIN product_images AS pi ON (pi.image_id = iv.image_id)
WHERE pi.pid = '$pid'
&& iv.image_type_id = '$image_type_id' ";
$stmt = $this->query($select);
$rows = $stmt->fetchAll();
return $rows;
So I dont always have to define db variables in each method and have mysql passwords all over the place. Is there a way to use $this instead of having to instantiate a new $db Zend_DB Factory??

Answer 1

Ok figured it out. The solution is not very elegant buts works and is portable.
My setup consists of multiple DBs, so in Bootstrap.php I have:
protected function _initDatabase() {
$resource = $this->getPluginResource('multidb');
$resource->init();
Zend_Registry::set('db', $resource->getDb('db'));
Zend_Registry::set('shopdb', $resource->getDb('shopdb'));
}
In Application.ini
resources.multidb.db.adapter = PDO_MYSQL
resources.multidb.db.host = 127.0.0.1
resources.multidb.db.username = user
resources.multidb.db.password = userpassword
resources.multidb.db.dbname = dbone
resources.multidb.db.isDefaultTableAdapter = true
resources.multidb.db.default = true
resources.multidb.shopdb.adapter = PDO_MYSQL
resources.multidb.shopdb.host = 127.0.0.1
resources.multidb.shopdb.username = user
resources.multidb.shopdb.password = userpassword
resources.multidb.shopdb.dbname = dbtwo
resources.multidb.shopdb.isDefaultTableAdapter = false
in index.php
$config = new Zend_Config_Ini(APPLICATION_PATH . "/configs/application.ini");
Zend_Registry::set('settings', $config);
Then (the not very elegant bit) in Models add an init() method
protected $db;
public function init() {
$settings = Zend_Registry::get('settings');
$adapter = $settings->production->resources->multidb->shopdb->adapter;
$params = array(
'host' => $settings->production->resources->multidb->shopdb->host,
'username' => $settings->production->resources->multidb->shopdb->username,
'password' => $settings->production->resources->multidb->shopdb->password,
'dbname' => $settings->production->resources->multidb->shopdb->dbname,
);
$this->db = Zend_Db::factory("$adapter", $params);
}
And then you can use $this->db in other methods in the Model class, eg:
public function getProductImages($pid, $image_type_id) {
$select = "SELECT iv.*
FROM image_variations AS iv
LEFT JOIN images AS i ON (i.image_id = iv.image_id)
LEFT JOIN product_images AS pi ON (pi.image_id = iv.image_id)
WHERE pi.pid = '$pid'
&& iv.image_type_id = '$image_type_id' ";
$stmt = $this->db->query($select);
$rows = $stmt->fetchAll();
return $rows;
}
It works but it still seems like there should be an easier way...
