Rails Code Snippets

Hi,

In my rails application I usually copy some usefull scripts from my previous project.
May be it's very interesting for you.

  def stylesheet(*args)
    content_for(:header) { stylesheet_link_tag(*args.map(&:to_s)) }
  end

  def javascript(*args)
    args = args.map { |arg| arg == :defaults ? arg : arg.to_s }
    content_for(:header) { javascript_include_tag(*args) }
  end

  def script(&block)
    content = capture(&block)
    concat("", block.binding)
  end

  def content_for_script(place = :header, &block)
    content = capture(&block)
    content_for place do
      script(&block)
    end
  end

  def google_analytics(code)
    %(
         script type='text/javascript'
          var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
          document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
          try {
          var pageTracker = _gat._getTracker("#{code}");
          pageTracker._trackPageview();
          } catch(err){}
        /script
      )
  end


 class String
   def self.random_alphanumeric(size=64)
     s = ""
     size.times { s << (i = Kernel.rand(62); i += ((i < 10) ? 48 : ((i < 36) ? 55 : 61 ))).chr }
     s
   end
 end

See you.
