Rails - Aug 2006 - Polymorphic Not Updating after deleting join

Using the example in the docs if I say

@folder.items

and I list the items, everything lists fine. If I delete a
''linking'', I
still get the same list. Shouldn''t I get one less item even though the 
other two db''s haven''t been updated?

If you delete a join model record, you have to reset or reload the 
:items" has_many :through association for it to notice the change.  You 
can say @folder.items(true) to return the reloaded list, or 
@folder.items.reset to just clear the in-memory cache of items.
