A simple way to use has_many between form objects using Virtus.The problem I had was to get validations working with fields_for in the view, but still have the flexibility and full control using virtus instead of active record models.And I added a way of checking for sanitised args in rails 4.
# encoding: utf-8
class AlbumForm < BaseForm
has_many :songs, class_name: 'SongForm'
validates :songs, form_collection: true
end

Rake task to copy assets between S3 buckets. Requires the aws-s3 gem (http://amazon.rubyforge.org/)
# add a new "put_copy" method to the Amazon client's S3Object class
# to enable copying an object from 1 bucket to another
# http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html
class AWS::S3::S3Object
def self.put_copy(source_key, target_key, source_bucket, target_bucket, options = {})
original = open(url_for(source_key, source_bucket))
default_options = { :content_type => original.content_type }
store(target_key, original, target_bucket, default_options.merge(options))
acl(target_key, target_bucket, acl(source_key, source_bucket))
end

A nice delete confirmation modal in Rails courtesy of Bootstrap

Here's what you get.

Some JavaScript

// Delete confirmation modals
$('#delete-confirm').on('show', function() {
  var $submit = $(this).find('.btn-danger'),
      href = $submit.attr('href');
  $submit.attr('href', href.replace('pony', $(this).data('id')));
