Doctrine does the proxy evaluation based on loaded field count. It does not evaluate which fields are loaded on field-by-field basis. The reason for this is simple: performance. Field lazy-loading is very rarely needed in PHP world, hence introducing some kind of variable to check which fields are loaded would introduce unnecessary overhead to basic fetching.

++ Overriding the constructor
Sometimes you want to do some operations at the creation time of your objects. Doctrine doesn't allow you to override the Doctrine_Record::__construct() method but provides an alternative:
<code type="php">
class User extends Doctrine_Record
{
public function construct()
{
$this->name = 'Test Name';
$this->do_something();
}
}
</code>
The only drawback is that it doesn't provide a way to pass parameters to the constructor.
