Model objects linked directly to db tables?

[eluser]coldscooter[/eluser]
I would like to treat my models as objects that are directly linked to database.

So I could something like this in my controllers:

//To save a new password
$this->load->model('user');
$this->user->password = 'new_password';
$this->user->save();


Is there a library out there that would do something like this for me?
