Create temporary table in CakePHP and load it as a Model

问题

My plan is to create a temporary table using the $this->Model->query(); method then load it as a Model but I'm getting an error staying "Missing Database Table". Turning on debug to level two shows that the temporary table is success fully created but for some reason, when I try and load it as a model it doesn't work. It looks like cake doesn't even try to see if the table exists as there is no "SHOW FULL COLUMNS FROM ...' query being displayed. Not sure how to force cake to check for its existence.

$tmpModel = 'tempModel';
$tmpTable = 'temp_models';

$this->Model->query('CREATE TEMPORARY TABLE `'.$tmpTable ... );
$this->loadModel($tmpModel);

Thanks in advance.

$tmpModel = 'TempModel'; // CamelCase

also try, ClassRegisty::init($tmpModel);

final issue may be cache. but dont think so

Ok, after looking around a bit I have found a solution that works. The problem was that Cake had already loaded the models caches at page load so used them as reference to the existence of a table. To resolve this problem I used "App::import('Model', $tmpModel);" which created the new modelCache allowing the loadModel script to run successfully.

$tmpModel = 'tempModel';
$tmpTable = 'temp_models';

$this->Model->query('CREATE TEMPORARY TABLE `'.$tmpTable ... );
App::import('Model', $tmpModel);
$this->loadModel($tmpModel);

Thanks anyway
