I am wondering how I could use data from a Model B while I am validating Model A, here to check if an entered Banknumber is a correct one:
My Users specify their bankaccount during the registration. E.g. the "banknumber". I am validating this the normal way in my user.php model
var $validate = array(
'banknumber' => array(
'minLength' => array(
'rule' => array('minLength', 8),
'message' => '...',
'required' => true,
),
Now I want to know if the entered Banknumber is a real one, so I got a table "Banks" in my DB with all real Banknumbers, and I am using some own validation functions which I specify in app_model.php.
function checkBankExists($data) {
if (!$this->Bank->findByBanknumber($data)) {
return false;
} else {
return true;
}
}
But this is never working, because while I am validating the User-Model, I can only use this one in an app_model - function, accessing it with $this->name or so... a $this->Bank is NOT possible, I get:
Undefined property: User::$Bank [APP\app_model.php
Call to a member function findByBanknumber() on a non-object
Is there ANY way to import/access other models in a function in app_model.php?
Thank you!
ClassRegistry should generally be used instead of AppImport as AppImport only loads the file, rather than registering it properly, cake style.
Using the example above.
$bnk = ClassRegistry::init('Bank');
$bnk->findByBanknumber($data);
