Composite primary key can be used efficiently in association tables (tables that connect two components together). It is not recommended
|
|
to use composite primary keys in anywhere else as Doctrine does not support mapping relations on multiple columns.
|
|
|
|
|
|
|
|
Due to this fact your doctrine-based system will scale better if it has autoincremented primary key even for association tables.

<code type="php">
|
|
class Groupuser extends Doctrine_Record {
|
|
public function setTableDefinition() {
|
|
$this->hasColumn('user_id', 'integer', 20, 'primary');
|
|
$this->hasColumn('group_id', 'integer', 20, 'primary');
|
|
}
|
|
}
