def aws_image_tag(image,options={})
	#	in console @controller is nil
	protocol = @controller.try(:request).try(:protocol) || 'http://'
	host = 's3.amazonaws.com/'
	bucket = ( defined?(RAILS_APP_NAME) && RAILS_APP_NAME ) || 'ccls'
	src = "#{protocol}#{host}#{bucket}/images/#{image}"
	alt = options.delete(:alt) || options.delete('alt') || image
	tag('img',options.merge({:src => src, :alt => alt}))
end

#button_link_to(title, url, options = {}) ⇒ Object

This style somehow for some reason actually submits the request TWICE? In many cases, this is no big deal, but when using it to send emails or something, the controller/action is called twice resulting in 2 emails (if that’s what your action does) I’d really like to understand why.

#old_button_link_to(title, url, options = {}) ⇒ Object

This creates a button that looks like a submit button but is just a javascript controlled link. I don’t like it.
