A way to accept the same XML input as model.to_xml generates as output (see http://stackoverflow.com/questions/4052677/rails-nested-resources-input-vs-output-format-inconsistency for details)
class ApplicationController < ActionController::Base
private
def fix_nested_attribute_structure(data = nil, model = nil)
unless data
# guess data based on current controller
data = params[self.class.to_s.sub('Controller', '').singularize.underscore.to_sym]
end
unless model

Using Sprockets 2 in Rails 3.0.x with CoffeeScript & SASS
UPDATE: Please see some of the forks for an updated version of this guide. I
myself have moved onto the Rails 3.1 betas to get the asset pipeline. But if
you want to stay on stable there are other folks who are keeping this guide
relevant despite the changes constantly occurring on Sprockets 2. The comments
on this gist will lead you to the right forks. :)
Some brief instructions on how to use Sprocket 2 in Rails to get CoffeeScript

Sprocket 2 in Rails 3.0.x ala Rails 3.1
Some brief instructions on how to use Sprocket 2 in Rails to get CoffeeScript
powered JS and SASS powered CSS with YUI compression all via the magic of rack.
This stuff will be native in Rails 3.1 and the layout of the files on the
filesystem will be different but this guide will get you working with it
while we wait for all that to finalize.
Ignore the number prefixes on each file. This is just to ensure proper order in the Gist.
It's based on eric1234 gist https://gist.github.com/911003. ijust made it 3.1 compliant in terms of convention
