Hmmmph, I was wondering that myself. The easy way is to do what's suggested above, but duplicate and entry for each relationship:
Eg. When Bob becomes Tim's friend (in the before/afterSave) force and entry that makes Tim Bob's friend. Of you could have one relationship and simply check the "other direction" logically in your controllers. But I don't think there are any easy Cake answers. -- Baz L Web Development 2.0: Web Design, CakePHP, Javascript http://www.WebDevelopment2.com/ On Nov 12, 2007 9:14 PM, mbavio <[EMAIL PROTECTED]> wrote: > > Christopher: > > I understand the basics behind Cake´s HATBM, but I do not understand > how to implement here...
