MVC model default values

There is support for @Column(..., default=value) and this is stored in the model meta data. This value is never used as a default value when creating objects with fields that have no value set.

I noticed that if the DBMS has a default column value, DEFAULT is used in the INSERT INTO table (...) VALUES (...) query. I would expect the annotated default value to be used, for the two reasons that a MVC model should hide DBMS logic and that the DBMS table can be out of sync with the MVC model. After all, the annotated default is stored in the model's meta data.

How can I construct a new object, using annotated defaults?

An example:

class User extends Model
{
    /**
     * @Identity
     * @Primary
     * @Column(type="integer", nullable=false)
     */
    private $ID;

    /**
     * @Column(type="string", length=32, default="John Doe")
     */
    private $name;
}

$user = new User();
$user->save(); // I expect $user to have $user->name set to 'John Doe', at least in the DBMS.
               // Instead it uses the default from the DMBS.
