Supporting Mobile Devices in Ruby on Rails

Question

What is the best way to develop a rails application that has special views for different mobile devices? Basically I'm looking for something like this ASP.NET MVC solution: http://www.hanselman.com/blog/MixMobileWebSitesWithASPNETMVCAndTheMobileBrowserDefinitionFile.aspx

Answer 1

Two articles that use the iPhone as an example of serving up a different view based on a mobile sub-domain or a by detecting the user-agent. Essentially you'll create a different view using something like viewname.iphone.erb or viewname.mobile.erb and set the request.format variable to iphone or mobile respectively.

Answer 2

You might be looking for mobile_fu. It's a plugin that automatically changes the Rails format from :html to :mobile for Nokia, Blackberry, iPhone and Palm users. You can then just provide an {action}.mobile.erb to complement {action}.html.erb and it will render the mobile view. If you need something more fine-grained, it allows you to do:

is_mobile_device?

and there's various other helper methods

Answer 3

I recently wrote an article about this which you might find useful:

Hope that helps
