Hi folks

I have just been trying to get onBeforeWrite to perform some actions based on writing to a DataObjectDecorator, which in this case extends the Member DataObject.

I had hoped this would work right off the bat, but it doesn't seem to.

My onBeforeWrite function seems to be called ok within the DataObjectDecorator, but the objects do not seem to available to it, so no $this->ID, $this->changed etc....

Anyone any ideas?

Cheers

Use $this->owner->ID instead, that's how you access the decorated object.

Hey mat

Yep, but the changed + original objects do not seem to be available....

Show the code?

Inside the DataObjectDecorator I've created a new function which uses:

$this->owner->ID

Same way. Everything you add with extraStatics will become part of the decorated class:

<?php

class MyDataObjectDecorator extends DataObjectDecorator {
	
	function extraStatics() {
		return array(
			'db' => array(
				'MyField' => 'Varchar(255)'
			),
			'has_one' => array(
				'SomeImage' => 'Image'
			);
	}
	
	function getLowerCasedMyField(){
		return strtolower($this->owner->MyField);	
	}
	
	function getSomeImageTitle(){
		if($this->owner->SomeImage()){
			return $this->owner->SomeImage()->Title;
		}
	}
}

rbquirke, you wont be able to access changed and original as they are private/protected respectively. However, you can use $this->owner->getChangedFields() and $this->owner->isChanged()
