以下型号:
class User extends Doctrine_Record {
public function setTableDefinition() {
$this->hasColumn ( 'iron', 'integer', 4 );
}
public function setUp() {
$this->hasMany ('Field as Fields', array(
'local' => 'id',
'foreign' => 'owner_id'
));
}
}
class Field extends Doctrine_Record {
public function setTableDefinition() {
$this->hasColumn('owner_id','integer',4);
$this->hasColumn('ressource_id','integer',4);
$this->hasColumn('ressource_amount','integer','2');
}
public function setUp() {
$this->hasOne('User as Owner',array(
'local' => 'owner_id',
'foreign' => 'id'
));
}
}
我尝试遵循 DQL:
$sqlRessourceUpdate = Doctrine_Query::create()
->update('Field f')
->set('f.Owner.iron','f.Owner.iron + f.ressource_amount')
->where('f.ressource_id = ?',1);
结果:
'Doctrine_Query_Exception' with message 'Unknown component alias f.Owner'
基本上我只想根据字段的值更新字段所有者的“铁”属性
