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

i need to correct myself

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

and you simply use it this way:

//in views
if (Model::isRent($book['Book'])) {...}

this way it it can be used in any iteration as well
