+++ Refreshing records
Sometimes you may want to refresh your record with data from the database, use {{Doctrine_Record::refresh()}}.
<code type="php">
$user = $conn->getTable('User')->find(2);
$user->name = 'New name';
// oups, I want to refresh the name
$user->refresh();
</code>
++++ Refreshing relationships
The {{Doctrine_Record::refresh()}} method can also refresh record relationships, but you need to specify them on the query.
<code type="php">
$user = Doctrine_Query::create()->from('User')->leftJoin('Groups')->where('id = ?')->fetchOne(array(1));
$group = Doctrine_Query::create()->from('Group')->leftJoin('Users')->where('id = ?')->fetchOne(array(1));
$userGroup = new UserGroup();
$userGroup->user_id = $user->id;
$userGroup->group_id = $group->id;
$userGroup->save();
// get new group on user
$user->refresh(true);
// get new user on group
$group->refresh(true);
</code>
+++ Deleting records
Deleting records in Doctrine is handled by {{Doctrine_Record::delete()}}, {{Doctrine_Collection::delete()}} and {{Doctrine_Connection::delete()}} methods.
