Every controller is a subclass of <code>ApplicationController</code>. Any methods or data in <code>ApplicationController</code> are therefore available to all other controllers.

			=== Flash Hash ===
			Useful for sending messages from controller to view. Use this in controller:
			<source lang="ruby">
			flash[:rubber_ducky] = "You're the one!"
			</source>
			and make it visible in the view with
			<source lang="ruby">
			<%= flash[:rubber_ducky] %>
			</source>

			Two special shorthand cases: <code>notice</code> and <code>alert</code>:
			This code in controller:
			<source lang="ruby">
			format.html { redirect_to(@article, :notice => 'Article was successfully created.') }
			</source>
			and this in view:
			<source lang="ruby">
			<p class="notice"><%= notice %></p>
			</source>

			=== Redirecting ===
			Use an object as shorthand for redirection:
			<source lang="ruby">
			redirect_to(@article)
			</source>
			is a shortcut equivalent to
			<source lang="ruby">
			redirect_to(article_path(:id => @article.id))
			</source>
