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:
