//     Backbone.Rails.js
//
//     Makes Backbone.js play nicely with the default Rails setup, i.e.,
//     no need to set
//       ActiveRecord::Base.include_root_in_json = false
//     and build all of your models directly from `params` rather than
//     `params[:model]`.
//
//     Load this file after backbone.js and before your application JS.

// First, let's define a widget/plugin called "foo"

// Either using jQuery's $.fn plugin namespace, for simple stateless plugins...
$.fn.foo = function(){

  // In this scope, this refers to the element on which the plugin foo() was called 
  // manipulate it and return this at the end, so it can be chainable

# MOTIVATION:  As rails apps are growing, people are noticing the drawbacks
# of the ActiveRecord pattern.  Several apps I have seen, and several
# developers I have spoken to are looking towards other patterns for object
# persistence.  The major drawback with ActiveRecord is that the notion
# of the domain object is conflated with what it means to store/retrieve
# it in any given format (like sql, json, key/value, etc).
#
# This is an attempt to codify the Repository pattern in a way that would
# feel comfortable to beginner and seasoned Ruby developers alike.
