ModelAdmin saves twice on adding?
25 January 2010 at 1:34pm Last edited: 25 January 2010 1:35pm
Hi,
I have a DataObject (A) in ModelAdmin that's supposed to save data to a record on another DataObject (B) in an onBeforWrite-method.
But if I'm adding a new DataObjectA, it doesn't save to one record, but to two records on DataObjectB...Does someone know what's happening here and how to solve this?
Below is the structure:class DataObjectA extends DataObject{
static $db = array(
"titleA" => "Varchar",
);static $has_many = array(
"DataObjectB" => "DataObjectB",
);public function onBeforeWrite() {
$myDataObjectB = new DataObjectB();
$myDataObjectB->titleB = "NewTitle";
$myDataObjectB->write();parent::onBeforeWrite();
}
class DataObjectB extends DataObject{
static $db = array(
"titleB" => "Varchar",
);static $has_one = array(
"DataObjectA" => "DataObjectA"
);}
BTW If DataObjectA exists and you click save, it will save just one new record on DataObjectB

For a new record there are two operations - a 'create' and an 'update'. That is, onBeforeWrite will be called twice. The first time, the ID will be 0, so you can use that to figure out what operation is happening.
Basically, if you wrap your code in "if($this->ID) { ... }" it should fix your problem.
