Rails - Jul 2005 - Implementing a tree structure

I have a database layout, where one of the fields is reference to another
row in the same table.

create table rdf_classes (
	id		int		not null auto_increment,
	name		varchar(100)	not null,
	...
	parent_id	int		not null,
	primary	key (id)
);

So what do I need to add to ''RdfClass'' that
''instance.parent'' will return
the appropriate RdfClass instance?

Or is there an entirely different way of achieving that?

Thanks,

-max

Look in the docs for acts_as_tree
