Kohana 3 ORM: How to perform query with 2 many to many relationships

Question

I have a products model with 2 many to many relationships defined.

protected $_has_many = array
(
\'foodcats\' => array(\'model\' => \'foodcat\',   \'         


        

Answer 1

Simply; you don't. What you need is INNER JOIN, like;

ORM::factory('product')
->join('foodcats','INNER')
->on('foodcats.id','=',$foodcats_id)
->join('foodgroups','INNER')
->on('foodgroups.name','=',$foodgroups_name)
->find_all();

Answer 2

in Kohana 3.1 without using DB::expr, will give unknown column error.

ORM::factory('product')
->join('foodcats','INNER')
->on('foodcats.id','=', DB::expr($foodcats_id))
->join('foodgroups','INNER')
->on('foodgroups.name','=', DB::expr($foodgroups_name))
->find_all();
