R – What are best practices for using frames (or iframes) with Rails

I've used the extremely popular Whenever on projects that rely heavily on scheduled tasks, and it's great. It gives you a nice DSL to define your scheduled tasks instead of having to deal with crontab format. From the README:

Whenever is a Ruby gem that provides a clear syntax for writing and deploying cron jobs.

Example from the README:

every 3.hours do
  runner "MyModel.some_process"       
  rake "my:rake:task"                 
  command "/usr/bin/my_great_command"
end

every 1.day, :at => '4:30 am' do 
  runner "MyModel.task_to_run_at_four_thirty_in_the_morning"
end

I'd stay away from framesets at all costs. They are valid in terms of the HTML 4 specification but they offer poor cross device support. Most mainstream browsers will display a frameset as intended, but more specialised browsers (like those found on mobile phones) tend to mess them up and a lot of cases make the site unusable.

I suspect there are also accessiblity concerns, but I imagine they would also exist for iframes as well.

Something else to consider is presentation. If you use framesets, you are effectively restricting the design of your website to the parameters of the frameset (this frame sits on the top, this frame sits on the bottom). Whereas, an iframe is just another element on the page and can be manipulated much as any other element with CSS, allowing you to radically redesign your site without touching the HTML.
