Rails - Aug 2009 - Using URL path in REST app as ID

I''m a Rails newbie, so please bear with me. I want to use the URL as
the
ID for a RESTful resource, but using the path after the controller. The
remaining portion of the URL would be the ID, rather than an integer.

So rather than just:

http://example.org/widgets/1

I want to use:

http://example.org/widgets/foo
http://example.org/widgets/foo/bar
http://example.org/widgets/foo/bar/baz

where foo, foo/bar and foo/bar/baz are all Widgets, not nested resources.

In the controller I''d like to do something like

@widget = Widget.find(params[:path])

where path is a string column defined as a primary key (or unique)
containing strings like ''foo'', ''foo/bar'' and
''foo/bar/baz''

Is this possible?
