Question

i have two values. one represents a number of objects

$a = $product->count_all();

$first = Model::factory('product')->sale($sale_id)->find();

i need the sum between the two. the second returns the first id that satsfies the query conditions. how can i convert the $first variable to int in kohana or how can i make this sum?? thank you!

1. Use $_ignored_columns for it:

   protected $_ignored_columns = array('count');
   

   So, you can initialize it
   ($first->count = $a;) and get as a
   model column ($count =
$first->count;).

2. Create special method get_count() in your
   model:

   protected $_row_count;
   
   public function get_count()
   {
       if ( $this->_row_count === NULL)
       {
            $this->_row_count = ORM::factory($this->_object_name)->count_all();
       }
   
       return $this->_row_count;
   }
