unable to delete relationship with datamapper using delete()

@johnmerlino,

The issue here is that Datamapper fails to automagically guess the relationship, because it's a self relationship. You have the same model on both sides of the relation, so it picks the first one it can find. Which in your case is the wrong one, and that's why your relations are the wrong way around.

You will have to specify on which relationship you want to operate:

Code:

// save an explicit relation
$parent = new Category(1);
$child = new Category(2);

// related them
$parent->save_related_category($child);

// and delete it
$parent->delete_related_category($child);
