Okay, so I just couldn't leave this alone :)
I implemented the following, which works and even brings in the
'contain' info. However there is still a small problem...
// books_controller.php view()
$similar = $this->Book->similar_books($genre_id, $limit);
// model book.php
$similarBooks = $this
Thanks brian. I checked those out and after a few attempts I got it
workingthat is until I tried to add a 'contain'.
If I try to bring in some more data with the contain then the whole
thing returns nothing. If I comment out the 'group' then I get data
again, although this is the wrong data.
I didn't realise it was HABTM. That changes things. See these posts:

brian, when I try this though I get an " Unknown column
'Book.genre_id' in 'where clause' " error.
SELECT `Book`.`id`, `Book`.`title`, `Book`.`slug`, `Language`.`id`,
`Language`.`name` FROM `books` AS `Book` LEFT JOIN `languages` AS
`Language` ON (`Book`.`language_id` = `Language`.`id`) WHERE

I'd also call the function genre() in case I ever wanted to add a
broader similar() functionality.

Okay, so after more searching around I found a post by pkclarke who
makes use of a search on the join table, and then uses a find() with
those results.
I still have the feeling this is not the best way it should be done,
but I think this approach will allow me to move forwardand no

Hi Joe,
During my experimentations I did come up with something similar, but
one of the problems is how to set the conditions to work on the Genre
ID.
So, I have a book that has two genre, "Mystery" (id=5) and "Short
Story" (id=20) and if I only try to search with say, "Mystery";
$id = 5;
$this
You've currently got your similar() function in your
genres_controller, whereas the primary model for the query is the Book
model (as it's finding related *books*, not genres).
I believe the following would be a more scalable approach.
Place your similar() function into your Book model. (So it w
In my books view.ctp, I want to have a list of 5 books that are
related via the genres data, which has a HABTM relationship. Although
I can do this by placing a function similar() in the
genres_controller, I have to call it from the view with requestAction.
// genres_controller.php
function sim
