Kohana ORM update column on save

Question

I'm fairly new to ORM, but what I am trying to do is insert a new comment in to the MySQL database and update users table.

So I have two tables, users and comments.

Now when i call save() method on comments object i would like to insert that comment in to comments table and also update user written_comments column in users table.

The part where I only need to insert comment is easy and I've already done it.

Problem comes with the update query where i need to update users table and set written_comments + 1 where id = $userId

I have found documentation about relations between objects, but i can't figure this out.

I am using Kohana 3.3 version.

My comments class right now is empty:

class Model_Comments extends ORM{

}

And I'm extending Auth user class

class Model_User extends Model_Auth_User  {

}

Any help at all would help a lot, thanks.

If you want use only ORM, try write something like this after saving a comment

$user = ORM::factory('User', $userId);
if($user->loaded()){
   $user->set('written_comments', $user->written_comments + 1)->update();
}

There are no way to bind callback on ORM::save(). You can only check saving a comment into database with ORM::loaded() method.
