So, this helps a lot when testing applications using RSPEC that use the authlogic gem for authentication. 
Just require and include the following module in your rspec file. Then you can simply write things like:

  before(:each) do
    login_as_user
  end

at the top of your specs, and you should be good to go...

module ControllerHelpers

class Book < ActiveRecord::Base
  has_one :author
  has_many :pages

  accepts_nested_attributes_for :author, :pages
end

accepts_nested_attributes_for :author, 
  :reject_if => proc { |attributes| attributes['name'].blank? }

Just discovered this: an easy way to humanize the attributes of a model. Allows you to rename the database column name to something more reasonable. Makes for nicer, more understandable error messages back to the user.

class User < ActiveRecord::Base

  HUMANIZED_ATTRIBUTES = {
    :user_email => "E-mail address"
  }

  def self.human_attribute_name(attr)
    HUMANIZED_ATTRIBUTES[attr.to_sym] || super

document.observe("widget:frobbed", function(event) {
  console.log("Element with ID (" + event.target.id +
   ") frobbed widget #" + event.memo.widgetNumber + ".");
});

var someNode = $('foo');
someNode.fire("widget:frobbed", { widgetNumber: 19 });

//-> "Element with ID (foo) frobbed widget #19."
