cakephp checking for duplicate rows - php

Question

I have been at this for 5 days now. I read all the answers I could here, I have tried any options I could I cannot find how to fix this cache issue.
I am using cakephp 2.4.4 which could be upgraded but I did not see my issue in any of the change.log
Percona MYSQL 5.6 Innodb
We have a model that we call in a loop to insert rows
App::import('Model', 'TableA');
$TableA = new TableA();
foreach($rows as $row){
$TableA->InsertRow($row);
}
Then we have the Model for TableA
I added a Unique Index on TableA.Sku to avoid duplicate entry
class TableA extends AppModel {
var $name = 'TableA';
var $cacheQueries = false;
var $validate = array();
function InsertRow($data){
$this->clear();
try {
$result = $this->find('first', array(
'fields' => array(
'TableA.id',
),
'conditions' => array(
'TableA.Sku' => $data['Sku'],
),
));
pr($result);
if(!isset($result['TableA']['id'])){
$data['TimeStamp'] = strtotime("now");
$this->save($data);
}
return TRUE;
}
catch (Exception $e) {
pr($e);
$resultNow = $this->find('first', array(
'fields' => array(
'TableA.id',
),
'conditions' => array(
'TableA.Sku' => $data['Sku'],
),
));
pr($resultNow);
}
}
}
The first loop $Rows has multiple time the same sku following each other
the first loop insert the row
the 2nd loop gives:
array
(
)
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'tue026991015' for key 'Sku'
INSERT INTO `ki`.`TableA` (`Sku`, `TimeStamp`) VALUES ('tue026991015', 1453858976)
Array
(
[TableA] => Array
(
[id] => 31951
)
)
I am also running in Debug Mode 2
In the 2nd loop the query should return the id and the loop should not try to insert the row but it is not.
I added var $cacheQueries = false; on top of the Model to avoid cashing. I am at a loss as to why this behavior is happening and how to avoid any mysql cashing for this function.

It happens when the user clicks "refresh" data or happens when you fill out the form and add user data gives? Which method you use to collect the GET or POST data?
