Registering Zend Database Adapter in Registry

Question

I am looking to register a reference to the main Database Adapter in the Registry during Bootstrapping so it can be used elsewhere in my site (specifically the Authorisation

Answer 1

Check the zend-documentation at : 15.5.3.3. Storing a Database Adapter in the Registry

http://framework.zend.com/manual/en/zend.db.table.html

$db = Zend_Db::factory('PDO_MYSQL', $options);
Zend_Registry::set('my_db', $db);

// Later...

$table = new Bugs(array('db' => 'my_db'));

something like that you're looking for?

Edit:
to load your configuration from an ini-file, use:
parse_ini_file($inifile)

;configuration.ini
host = 127.0.0.1
user = username
password = blabla

;yourfile.php
$options = parse_ini_file('configuration.ini');

$db = Zend_Db::factory('PDO_MYSQL', $options);

Thanks for the replies. Ive decided to change the accepted answer and post the solution I finally used - which is insanely simple in the end!!

This is basically based on Dcaunt's comment...

In the bootstrap class..

protected function _initDb()
{
    $resource = $bootstrap->getPluginResource('db');

    $db = $resource->getDbAdapter();

    Zend_Registry::set("db", $db);
}

Then access that elsewhere with...

$dbAdapter = Zend_Registry::get("db");

Thanks for the help and hopefully this helps someone else.

I didn't want to use the registry to store an object that I should be able to access, so I did a little digging. It turns out that the bootstrap is registered as the front controller parameter "bootstrap", which is accessible from any of your controllers as explained in this manual page for Zend_Application.

So in your controller classes you can get the db adapter that has been defined in your ini file like this:

$bootstrap = $this->getInvokeArg('bootstrap');
$resource = $bootstrap->getPluginResource('db');
$db = $resource->getDbAdapter();

If you are using Zend Framework 1.8 just do something like this in your controller/action:

class CreateorderController extends Zend_Controller_Action
{
    public function testAction()
    {
        //more code
        $users_obj = new Default_Model_Users(); //this would load the model using the Default namespace
        //more code
    }
}

My Defaul_Model_Users class would look something like this:

<?php
/**
 * application/models/Users.php
 */
class Default_Model_Users extends Zend_Db_Table
{
    protected $_table;

    public function getTable()
    {
        if(null === $this->_table) {
            $this->_table = new Default_Model_DbTable_Users();
        }
        return $this->_table;
    }

    public function fetchAll()
    {
        $result = $this->getTable()->fetchAll();

        return $result;
    }
}

And the part of the model which "interacts" directly with the database tables is found inside DbTable directory will look like this:

<?php
/**
 * application/models/DbTable/Users.php
 */
class Default_Model_DbTable_Users extends Zend_Db_Table_Abstract
{
    /** Table name */
    protected $_name = 'users';

    public function init()
    {
        $this->_db->setFetchMode(Zend_Db::FETCH_OBJ);
    }
}

Then I would have the same application.ini generated by Zend Framework with this small addition:

resources.db.adapter               = "PDO_MYSQL"
resources.db.params.host           = "localhost"
resources.db.params.dbname         = "mydb"
resources.db.params.username       = "root"
resources.db.params.password       = "password"

That is how I did without without having to change the bootstrap files.

Answer 5

If you're using Zend Framework 1.8+, and created your project with the command line tool, then it's as simple as registering your database settings in your application.ini config file.

resources.db.adapter = "PDO_MYSQL"
resources.db.params.host = "your.database.host"
resources.db.params.dbname = "database_name"
resources.db.params.username = "username"
resources.db.params.password = "password"
resources.db.isDefaultTableAdapter = true

If your database settings are preceded by resources.db you won't even need to do anything in your Bootstrap.php file because it will do it for you. Also, by setting the isDefaultTableAdapter setting to true, you can get an instance of your database adapter anywhere in your application.

$dbAdapter = Zend_Db_Table::getDefaultAdapter();
$authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter);

Answer 6

I have a method in my bootstrap to add the adapter to the registry. I'd prefer a cleaner solution, but it works:

protected function _initRegistry(){

    $this->bootstrap('db');
    $db = $this->getResource('db');

    $db->setFetchMode(Zend_Db::FETCH_OBJ);

    Zend_Registry::set('db', $db);
}
