RE: [Rails] REST and habtm relationship

I've got a habtm relationship that I'd really like to control

RESTfully

but I'm not sure how best to handle it.

REST hasn't changed the way habtm relationships work. You can implement
the habtm models as before. Then create the routes like so:

map.resources :genres do |genre|
  genre.resources :films
end

If you scaffold the resources, they'll need a little tweaking to get the
paths right but there's plenty of information on how to proceed out
there. (There's a fine example in AWDWR 2nd.)
