How to set condition in creating relation
  • IshworIshwor
    Hi there,
    I've two modals "Model_User" & "Model_Packagecart",
    User has many packages
    but I need only last package that is not expired.

    so I wrote this relation in Model_User :

    protected static $_has_many = array(
            'package' => array(
                'key_from' => 'id',
                'model_to' => 'Model_Packagecart',
                'key_to' => 'user_id',
                'conditions' => array(
                   'where'=>array(array('expired_at','>',time())),
                   'order_by' => array(
                        'id' => 'DESC'
                    ),
                   'limit'=>1,
                ),
            ),
        );

    But this shows error in Where condition, Also limit doesnot work but if i place 
    where=>array('id'=>1),
    it works.
    Can Anyone say what should I do?
    to get the last unexpired row??

    Thanks,
    Ishwor

    The problem here seems to be your lack of PHP knowledge. ;)

    You are using the function time() in a variable definition, and you are not allowed to, so that is the PHP syntax error you are getting.

    If you want define conditions based on runtime information, you need to use the init class method: 

        /**
         * filter packages on expiration timestamp
         */
        public static function _init()
        {
            parent::_init();

            // add a where clause, we need DB::expr here, we're injecting a literal
            static::$_has_many['package']['conditions']['where'] = array(array(['expired_at', '>', \DB::expr(time())));
        }
