In Doctrine all record relations are being set with {{hasMany}}, {{hasOne}}, {{ownsMany}} and {{ownsOne}} methods. Doctrine supports almost any kind of database relation from simple one-to-one foreign key relations to join table self-referencing relations.
+++ Relation aliases
Doctrine supports relation aliases through {{as}} keyword.
<code type="php">
class Forum_Board extends Doctrine_Record {
public function setTableDefinition() {
$this->hasColumn('name', 'string', 100);
$this->hasColumn('description', 'string', 5000);
}
public function setUp() {
// notice the 'as' keyword here
$this->ownsMany('Forum_Thread as Threads', 'Forum_Thread.board_id');
}
}
class Forum_Thread extends Doctrine_Record {
public function setTableDefinition() {
$this->hasColumn('board_id', 'integer', 10);
$this->hasColumn('updated', 'integer', 10);
$this->hasColumn('closed', 'integer', 1);
}
public function setUp() {
// notice the 'as' keyword here
$this->hasOne('Forum_Board as Board', 'Forum_Thread.board_id');
