Chapter 10: Component Overview 174 Listing 10-49 // test.php // ... $user->refresh(); Refreshing relationships The Doctrine_Record::refresh() method can also refresh the already loaded record relationships, but you need to specify them on the original query. First lets retrieve a User with its associated Groups: Listing 10-50 // test.php // ... $q = Doctrine_Query::create() ->from('User u') ->leftJoin('u.Groups') ->where('id = ?'); $user = $q->fetchOne(array(1)); Now lets retrieve a Group with its associated Users: Listing 10-51 // test.php // ... $q = Doctrine_Query::create() ->from('Group g') ->leftJoin('g.Users') ->where('id = ?'); $group = $q->fetchOne(array(1)); Now lets link the retrieved User and Group through a UserGroup instance: Listing 10-52 // test.php // ... $userGroup = new UserGroup(); $userGroup->user_id = $user->id; $userGroup->group_id = $group->id; $userGroup->save(); You can also link a User to a Group in a much simpler way, by simply adding the Group to the User. Doctrine will take care of creating the UserGroup instance for you automatically: Listing 10-53 // test.php // ... $user->Groups[] = $group; $user->save() Now if we call Doctrine_Record::refresh(true) it will refresh the record and its relationships loading the newly created reference we made above: Listing 10-54 // test.php ----------------- Brought to you by
Chapter 10: Component Overview 175 // ... $user->refresh(true); $group->refresh(true); You can also lazily refresh all defined relationships of a model using Doctrine_Record::refreshRelated(): // test.php Listing 10-55 // ... $user = Doctrine_Core::getTable('User')->findOneByName('jon'); $user->refreshRelated(); If you want to refresh an individual specified relationship just pass the name of a relationship to the refreshRelated() function and it will lazily load the relationship: // test.php Listing 10-56 // ... $user->refreshRelated('Phonenumber'); Deleting Records Deleting records in Doctrine is handled by Doctrine_Record::delete(), Doctrine_Collection::delete() and Doctrine_Connection::delete() methods. // test.php Listing 10-57 // ... $userTable = Doctrine_Core::getTable("User"); $user = $userTable->find(2); // deletes user and all related composite objects if($user !== false) { $user->delete(); } If you have a Doctrine_Collection of User records you can call delete() and it will loop over all records calling Doctrine_Record::delete() for you. // test.php Listing 10-58 // ... $users = $userTable->findAll(); Now you can delete all users and their related composite objects by calling Doctrine_Collection::delete(). It will loop over all Users in the collection calling delete one each one: // test.php Listing 10-59 // ... $users->delete(); ----------------- Brought to you by
