@blogica. Everyone who has made HABTM work is a guru as far as I'm concerned :)
To test what is being returned, I'm simply putting this in my controller view: $this->User->recursive = 1; debug($this->User->findAll()); the Group array is always empty. Do I need to put more stuff in the model? Can anyone share a working example? On Feb 23, 6:37 pm, "b logica" <[EMAIL PROTECTED]> wrote: > Oh, I'm by no stretch a Cake guru.
