Re: Why only pass $data to view instead of model instance?

i agree that this would be handy at some point
but it helps to keep the layers separated
otherwise one would be tempted to read/write to the DB in the views

i usually use static model methods for this

/** static **/
function isRent($data) {
return !empty($data[$this->alias]['rent_user_id']);
}

you can now call it anywhere (model, controller, behavior, view)
be sure you pass the data, though

PS: actually it has another upside. you can use it inside iterations
as well - like in foreach() loops in the view
