modern browsers don't need javascript for tooltips. js for legacy is easy enough

Created August 22, 2008 23:57
Allows attributes to be declared as lazy, meaning that they won't be # computed until they are asked for
View lazily calculated mixin.rb
# pseudoforked from mojombo: http://rubyisawesome.com/2007/10/13/lazy-mixin
# Before you ask--yes, this has a very specific use case and is not
# generally applicable to the problem of fine-grained lazy evaluation.
# But it does *exactly* what I need it to do. =)
# Allows attributes to be declared as lazy, meaning that they won't be
# computed until they are asked for. Just mix this module in:
#
# class Foo
View gist:7383
# never render the full layout if it's an XmlHttpRequest
class ApplicationController < ActionController::Base
def render(*args)
args.first[:layout] = false if request.xhr? and args.first[:layout].nil?
super
end
