[Deprecated] DMZ 1.5.3 (DataMapper OverZealous Edition)

[eluser]OverZealous[/eluser]
You almost had it:

Code:

if($r->product->get_by_id($p->id)->exists()) {
...

The exists() function — which just checks to see if $object->id is not empty() — was designed for that purpose. It is part of the core DataMapper.

But im not sure if there is a way to get a true false response without having to access the attributes and just use the objects themselves..

Also, I'm not sure what you meant by that.

Otherwise, there is no method within DM that is specifically designed to see if two objects are related.
