++ The Query Registry
|
|
Doctrine_Query_Registry is a class for registering and naming queries. It helps with the organization of your applications queries and along with that it offers some very nice convenience stuff.
|
|
|
|
The queries are added using the add() method of the registry object. It takes two parameters, the query name and the actual DQL query.
|
|
|
|
<code type="php">
|
|
$r = Doctrine_Manager::getInstance()->getQueryRegistry();
|
|
|
|
$r->add('all-users', 'FROM User u');
|
|
</code>
|
|
|
|
+++ Namespaces
|
|
|
|
The Query registry supports namespaces. The namespace is separated from the actual name with / -mark. If the name of the namespace is a record name the given record has all the named queries availible in its local scope.
|
|
|
|
<code type="php">
|
|
$r = Doctrine_Manager::getInstance()->getQueryRegistry();
|
|
|
|
$r->add('User/all', 'FROM User u');
|
|
$r->add('User/byName', 'FROM User u WHERE u.name = ?');
|
|
|
|
$user = new User();
|
|
|
|
// find the user named Jack Daniels
|
|
$user = $user->findOne('byName', array('Jack Daniels'));
|
|
|
|
// find all users
|
|
$users = $user->find('all');
|
|
