Hello,

I would like to know if it's possible to check if a writing action is the first in onAfterWrite method ? I know it's possible in onBeforeWrite method with a test on the existance of the ID :

function onBeforeWrite() {
parent::onBeforeWrite();

if (!$this->ID) {
// first write
}
else {
// next write when updates
}
}

But, in onAfterWrite ?

Thanks.

salut

so you trying to find if the DataObject you just wrote is the first in the DB?

function onAfterWrite(){
parent::onAfterWrite();
$list = DataObject::get($this->ClassName);
return $list->Count();
}


this will return number of DataObject

anyway, you don't need to check if you writing a new DataObject or just updating, th framework does it for you.

Hi - the first thing that comes into my mind, without delving into any code, is - if you've check it in onBeforeWrite, you can easily save the result in a property, and check the value of that property in onAfterWrite..
