I have CustomersController and i have in it
var $uses = array('Customer','CreditPackage');
so that it uses CreditPackage Model too.
I have the following function
function giveCredits($customer_id,$credit_package_id)
{
$credits=$this->CreditPackage->find("id=".$credit_package_id,array('credits'));
$credits=$credits['CreditPackage']['credits'];
$customer=$this->Customer->find("id=".$customer_id,array('credits','firm'));
$firm=$customer['Customer']['firm'];
$credits_left=$customer['Customer']['credits'];
$new_credits=$credits_left+$credits;
echo "Package_credits: ".$credits."<br>";
echo "Old_credits: ".$credits_left."<br>";
echo "New_credits: ".$new_credits."<br>";
$data=array('Customer'=>array('id'=>$customer_id,"credits"=>$new_credits));
$this->Customer->save($data);
//some rendering calls follow
}
credit_package_id regards The CreditPackage Model and i give to the
customer i want
the credits the according package has. The problem is the following
If the customer eg. has 0 credits and i give him a package with 1
credit I should get
printed.
Package_credits: 1
Old_credits: 0
New_credits: 1
But i get
Package_credits: 1
Old_credits: 1
New_credits: 2.
It seems as if the Customer->save function is first executed then the
Customer->find,and then
save again.
I have the same problem in other cases when for example i want to see
that the name i try to
insert in a table doesn't already exist. I put some code in the
beforesave function and i always
get the error that it already exists, because it first inserts it in
the table and then checks to see
if it exists.
Can anyone please help me?
