Hi everyone,
I need know how i can validate an model on relating models. For example, in:

$comment = new Model_Comment();
$comment->post = new Model_Post();
$comment->save();

How can i validate if $comment->post have a Model_Post, equal for example:

$comment = new Model_Comment();
$comment->date = date('Y-m-d');
$comment->save();

On validation function

public static function validate($factory)   {
        $val = Validation::forge($factory);
        $val->add_field('date', 'Date', 'required|valid_date'); //I wish know this, but for validating relatin models.

        return $val;

}

That is not going to be easy, since you can't validate the underlying key because it is only assigned a value when Model_Post is saved (assuming you have cascade_save on the relation).

Personally I would consider this a developer error, and not an input error, so I would not validate it, define the foreign key as NOT NULL, and capture the exception on save().
