Question
Following Models:
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'
));
}
}
And I try following DQL:
$sqlRessourceUpdate = Doctrine_Query::create()
->update('Field f')
->set('f.Owner.iron','f.Owner.iron + f.ressource_amount')
->where('f.ressource_id = ?',1);
Result:
'Doctrine_Query_Exception' with message 'Unknown component alias f.Owner'
Basicly I just want to update the "iron" attribute from the Field-Owner according to the fields' value
Solution
I am guessing you can't reference other tables like that in your query.
This may not be the best way but, here is what I do
$q = Doctrine_Query::create()
->select('*')
->from('Field')
->where('ressource_id = ?',1); //btw resource has one 's'
$field = $q->fetchone();
$field->Owner['Iron'] += $field->ressource_amount;
$field->save();
EDIT: Actually I don't know if that will work... this is more like what I do
$q = Doctrine_Query::create()
->select('*')
->from('Field')
->where('ressource_id = ?',1); //btw resource has one 's'
$field = $q->fetchone();
$user = $field->Owner;
$user['Iron'] += $field->ressource_amount; // I have never used a += like this, but in theory it will work.
$user->save();
