<?php
// MainModel hasMany SubModel

0 => array

//Query may product no SubModel records like below
1 => array

);
$combineResult = Set::combine($test['MainModel'], '/id', '/SubModel/id');
//returns array_combine warning because the found values are less then the
found keys
//how i got around this
$foundKeys = Set::extract('/id', $test['MainModel']);
$foundValues = Set::extract('/SubModel/id', $test['MainModel']);
if (count($foundKeys) == count($foundValues))
