i trying understand how encapsulation mechanism works in ruby : class def public_method_a; p private_method; end; private def private_method; 'a'; end; end class b < def public_method_b; p private_method; end; private def private_method; 'b'; end; end now when try run code, here : 1. > a.new.public_method_a => "a" 2. > b.new.public_method_b => "b" 3. > b.new.public_method_a => "b" basically, third call refers private method defined in b , not in a. java developer's point of view, encapsulation violation. call private_method should refer method defined in class call made. in ruby, seems more matter of context. right ? how can make sure private methods never called outside respective class ? doing wrong ? thank in advance help. nutshell: private means message can't have explicit receiver. that's all; nothing more. it removes message public api, nothing re

i trying multiple fields match ids(1, 2, 3) %% search. have tried make work 2 hours, hasn't worked though looks pretty simple. $ids = array ('1','2','3'); $result = $this -> model -> find ('all', array( 'conditions' => array( 'model.category like' => '%'.$ids.'%') )); i need somebody's help. i'd suggest build 'conditions' array separately. example: $ids = array ('1','2','3'); $conditions = array(); foreach($ids $id){ $conditions['or'][] = array( 'model.category like' => '%'.$id.'%') } $result = $this->model->find('all', array('conditions'=>$conditions));
