Last year I started playing around with using memoized private helper methods in my controllers instead of the traditional instance variable assigns we see in RoR controllers. Here's an example:

class PostsController < ApplicationController
  helper_method :new_post, :post, :posts
  
  def new; end
  def show; end
  def edit; end
 def index; end

Fix for strong_parameters when using accepts_nested_attributes_for

The following before filter looks for any Hash parameters where all the keys are integers and turns them into Arrays. It searches recursively to allow the used of nested attributes within nested attributes. This is necessary to circumvent a bug in the strong_parameters gem which was reported in April 2012. Given params like:

{
  "person" => {
    "dogs_attributes" => {
      "0" => {
 "name" => "Fido"
