Mobu

Mobu provides a Rails controller concern called DetectMobile. Mobu does server-side User Agent detection to categorize requests as mobile, tablet, or default. Mobu modifies your rails view paths based on the request type.

Install

Add this line to your Gemfile:

gem 'mobu'

Include the module in your ApplicationController:

class ApplicationController
  include Mobu::DetectMobile

Create directories for views_mobile and views_tablet:

mkdir app/views_mobile
mkdir app/views_tablet

Usage

Put the view/partial files that you want to override in the appropriate directories.

To allow mobile users to switch to the full site view, add a link to a mobile view:

app/views_mobile/_footer.haml

= link_to("View Full Site", prefer_full_site_url)

To allow full site users to switch to the mobile view, add a link to a default view:

app/views_mobile/_footer.haml

- if mobile_browser?
  = link_to("View Mobile Site", prefer_mobile_site_url)
